Mass–energy equivalence

Image

In physics, mass–energy equivalence is the concept that the mass of a body is a measure of its energy content. In this concept the total internal energy E of a body at rest is equal to the product of its rest mass m and a suitable conversion factor to transform from units of mass to units of energy. If the body is not stationary relative to the observer then account must be made for relativistic effects where m is given by the relativistic mass and E the relativistic energy of the body. Albert Einstein proposed mass–energy equivalence in 1905 in one of his Annus Mirabilis papers entitled "Does the inertia of a body depend upon its energy-content?"

The equivalence is described by the famous equation:

Image

where E is energy, m is mass, and c is the speed of light in a vacuum. The formula is dimensionally consistent and does not depend on any specific system of measurement units. For example, in many systems of natural units, the speed (scalar) of light is set equal to 1, and the formula becomes the identity E = m; hence the term "mass–energy equivalence". Albert Einstein created E=Mc^2. The equation E = mc^2 indicates that energy always exhibits relativistic mass in whatever form the energy takes. Additionally, in systems which have no momentum (or are viewed in their center of momentum frame), then the equation E = mc^2 also continues to be correct. Mass–energy equivalence in either of these conditions means that mass conservation becomes a restatement, or requirement, of the law of energy conservation, which is the first law of thermodynamics. Mass–energy equivalence does not imply that mass may be "converted" to energy, and indeed implies the opposite. Modern theory holds that neither mass nor energy may be destroyed, but only moved from one location to another. Mass and energy are both conserved separately in special relativity, and neither may be created nor destroyed. In physics, mass must be differentiated from matter, a more poorly defined idea in the physical sciences. Matter, when seen as certain types of particles, can be created and destroyed (as in particle annihilation or creation), but the precursors and products of such reactions retain both the original mass and energy, each of which remains unchanged (conserved) throughout the process. Letting the m in E = mc^2 stand for a quantity of "matter" (rather than mass) may lead to incorrect results, depending on which of several varying definitions of "matter" are chosen.

E = mc^2 has sometimes been used as an explanation for the origin of energy in nuclear processes, but mass–energy equivalence does not explain the origin of such energies. Instead, this relationship merely indicates that the large amounts of energy released in such reactions may exhibit enough mass that the mass-loss may be measured, when the released energy (and its mass) have been removed from the system.

Einstein was not the first to propose a mass–energy relationship (see the History section). However, Einstein was the first scientist to propose the E = mc^2 formula and the first to interpret mass–energy equivalence as a fundamental principle that follows from the relativistic symmetries of space and time.

Eleusinian Mysteries

The Eleusinian Mysteries (Greek: Ἐλευσίνια Μυστήρια) were initiation ceremonies held every year for the cult of Demeter and Persephone based at Eleusis in ancient Greece. Of all the mysteries celebrated in ancient times, these were held to be the ones of greatest importance. It is acknowledged that their basis was an old agrarian cult which probably goes back to the Mycenean period (c.1600-1100 BC) and it is believed that the cult of Demeter was established in 1500 BC. The idea of immortality which appears in syncretistic religions of antiquity was introduced in late antiquity. The mysteries represented the myth of the abduction of Persephone from her mother Demeter by the king of the underworld Hades, in a cycle with three phases, the "descent" (loss), the "search" and the "ascent", with main theme the "ascent" of Persephone and the reunion with her mother. It was a major festival during the Hellenic era, and later spread to Rome. The name of the town, Eleusís seems to be Pre-Greek and it is probably a counterpart with Elysion and the goddess Eileithyia.

The rites, ceremonies, and beliefs were kept secret and consistently preserved from a hoary antiquity. The initiated believed that they would have a reward in the afterlife. There are many paintings and pieces of pottery that depict various aspects of the Mysteries. Since the Mysteries involved visions and conjuring of an afterlife, some scholars believe that the power and longevity of the Eleusinian Mysteries came from psychedelic agents.

(...)

Some scholars have proposed that the power of the Eleusinian Mysteries came from the kykeon's functioning as a psychedelic agent. Barley may be parasitized by the fungus ergot, which contains the psychoactive alkaloids lysergic acid amide (LSA), a precursor to LSD and ergonovine. It is possible that a psychoactive potion was created using known methods of the day. The initiates, sensitized by their fast and prepared by preceding ceremonies (see set and setting), may have been propelled by the effects of a powerful psychoactive potion into revelatory mind states with profound spiritual and intellectual ramifications. It is probable that the goddess Demeter brought the poppy with her from Creta to Eleusis and it is certain that opium was produced from poppies in Creta.

While modern scholars have presented evidence supporting their view that a potion was drunk as part of the ceremony, the exact composition of that agent remains controversial. Modern preparations of kykeon using ergot-parasitized barley have yielded inconclusive results, although Alexander Shulgin and Ann Shulgin describe both ergonovine and LSA to be known to produce LSD-like effects. Terence McKenna speculated that the mysteries were focused around a variety of Psilocybe mushrooms. Various other entheogenic plants, such as Amanita muscaria mushrooms, have also been suggested, but at present no consensus has been reached.[36] The size of the event may rule out Amanita or Psilocybe mushrooms as active ingredient, since it is unlikely that there would have been enough wild mushrooms for all participants. However a recent hypothesis suggests that Psilocybe cultivation technology was known in ancient Egypt, from which it could easily have spread to Greece.

Another theory is that the kykeon was an Ayahuasca analog involving Syrian Rue (Peganum harmala), a shrub which grows throughout the Mediterranean and also functions as a monoamine oxidase inhibitor. The most likely candidate for the DMT containing plant, of which there are many in nature, would be species of Phalaris and/or Acacia. Other scholars however, noting the lack of any solid evidence and stressing the collective rather than individual character of initiation into the Mysteries, regard entheogenic theories with pointed skepticism. There is little beyond tenuous circumstantial evidence to support the theory; indeed, the few facts that led to the theory's formation in the first place are then invoked as supporting evidence, a form of circular reasoning; the scientific method requires that confirming evidence, beyond the observations used to form the hypothesis, be supplied before granting its veracity. While this may be true, the Mysteries are generally accepted to be associated with the consumption of some substance(s), possibly as a beverage, that induced visions and a feeling of oneness with at least mankind, if not the universe. This made the event particularly reliable, necessarily secret, in addition to special and certainly subject to strict sanctions if the secrecy were violated.

Use of potions or philtres for magical or religious purposes was relatively common in Greece and the ancient world. This would seem to argue against an entheogenic ceremony at Eleusis being so closely guarded a secret.

Indirect evidence in support of the entheogenic theory is that in 415 BC Athenian aristocrat Alcibiades was condemned partly because he took part in an "Eleusinian mystery" in a private house.

The range of what we think and do is limited by what we fail to notice. And because we fail to notice that we fail to notice, there is little we can do to change; until we notice how failing to notice shapes our thoughts and deeds.

DAEDALUS

or

Science and the Future

A paper read to the Heretics, Cambridge, on February 4th, 1923

by

J. B. S. Haldane


INTRODUCTION
I have slightly expanded certain parts of this paper since reading it. It has therefore probably lost any unity which it may once have possessed. It will be criticized for its undue emphasis on certain unpleasant topics. This is necessary if people are to be induced to think about them, and it is the whole business of a university teacher to induce people to think.

DAEDALUS, or, SCIENCE AND THE FUTURE
As I sit down to write these pages I can see before me two scenes from my experience of the late war. The first is a glimpse of a forgotten battle of 1915. It has a curious suggestion of a rather bad cinema film. Through a blur of dust and fumes there appear, quite suddenly, great black and yellow masses of smoke which seem to be tearing up the surface of the earth and disintegrating the works of man with an almost visible hatred. These form the chief part of the picture, but some where in the middle distance one can see a few irrelevant looking human figures, and soon there are fewer. It is hard to believe that these are the protagonists in the battle. One would rather choose those huge substantive oily black masses which are so much more conspicuous, and suppose that the men are in reality their servants, and playing an inglorious, subordinate, and fatal part in the combat. It is possible, after all, that this view is correct.

Had I been privileged to watch a battle three years later, the general aspect would have been very similar, but there would have been fewer men and more shell-bursts. There would probably, however, have been one very significant addition. Then men would have been running, with mad terror in their eyes, from gigantic steel slugs, which were deliberately, relentlessly and successfully pursuing them.

The other picture is of three Europeans in India looking at a great new star in the milky way. These were apparently all of the guests at a large dance who were interested in such matters. Amongst those who were at all competent to form views as to the origin of this cosmoclastic explosion, the most popular theory attributed it to a collision between two stars, or a star and a nebula. There seem, however, to be at least two possible alternatives to this hypothesis. Perhaps it was the last judgement of some inhabited world, perhaps a too successful experiment in induced radioactivity the part of some of the dwellers there. And perhaps also these two hypotheses are identical, and what we were watching that evening was the detonation of a world on which too many men came out to look at the stars when they should have been dancing.

These two scenes suggest, very briefly, a part of the case against science. Has mankind released from the womb of matter a Demogorgon which is already beginning to turn against him, and may at any moment hurl him into the bottomless void? Or is Samuel Butler's even more horrible vision correct, in which man becomes a mere parasite of machinery, an appendage of the reproductive system of huge and complicated engines which will successively usurp his activities, and end by ousting him from the mastery of this planet? Is the machine-minder engaged on repetition-work the goal and ideal to which humanity is tending? Perhaps a survey of the present trend of science may throw some light on these questions.

But first we may consider for a moment, the question of whether there is any hope of stopping the progress of scientific research. It is after all a very recent form of human activity, and a sufficiently universal protest of mankind would be able to arrest it even now. In the middle ages public opinion made it so dangerous as to be practically impossible, and I am inclined to suspect that Mr. Chesterton, for example, would not be averse to a repetition of this state of things. The late M. Joseph Reinach, an able and not wholly illiberal thinker, publicly advocated it.

I think, however, that so long as our present economic and national systems continue, scientific research has little to fear. Capitalism, though it may not always give the scientific worker a living wage, will always protect him, as being one of the geese which produce golden eggs for its table. And competitive nationalism, even if war is wholly or largely prevented, will hardly forego the national advantages accruing from scientific research.

If we look at the other most probable alternative the prospect is little more hopeful. In this country the labour party alone among political organizations includes the fostering of research in its official programme. Indeed as far as biological research is concerned labour may prove a better master than capitalism, and there can be little doubt that it would be equally friendly to physical and chemical research if these came to lead immediately to shortened hours rather than to unemployment. In particular there is perhaps reason to think that that form of sentimentalism which hampers medical research in this country by legislation would be less likely to flourish in a robust and selfish labour party of the Australian type than in parties whose members enjoy the leisure which seems necessary to the development of such emotional luxuries.

It is of course possible that civilisation may collapse throughout the world as it has done in parts of Russia, and science with it, but such an event would, in all probability, only postpone the problem for a few thousand years. And even in Russia we must not forget that first-rate scientific research is still being carried on.

The possibility has been suggested --- I do not know how seriously --- that the progress of science may cease through lack of new problems for investigation. Mr. Chesterton in The Napoleon of Notting Hill, a book written fifteen years or so ago, prophesied that hansom-cabs would still be in existence a hundred years hence owing to a cessation of invention. Within six years there was a hansom-cab in a museum, and now that romantic but tardy vehicle is a memory like the trireme, the velocipede, and the 1907 Voisin biplane. I do not suggest that Mr. Chesterton be dragged --- a heavier Hector --- behind the last hansom cab, but I do contend that, in so far as he claims to be a prophet rather than the voice of one crying in the wilderness, he may be regarded as negligible for the purposes of our discussion. I shall try shortly to show how far from complete are any branches of science at the present time.

But first a word on Mr. H. G. Wells might not be out of place. The very mention of the future suggests him. There are two points I wish to make about Mr. Wells. In the first place, considered as a serious prophet, as opposed to a fantastic romancer, he is singularly modest. In 1902, for example, in a book called ``Anticipations,'' he gave it as his personal opinion that by 1950 there would be heavier than air flying machines capable of practical use in war. That, he said, was his own view, though he was well aware that it would excite considerable ridicule. I propose in this paper to make no prophecies rasher than the above.

The second and more important point is that he is a generation behind the time. When his scientific ideas were formed, flying and radio-telegraphy, for example, were scientific problems, and the centre of scientific interest still lay in physics and chemistry. Now these are commercial problems, and I believe that the centre of scientific interest lies in biology. A generation hence it may be elsewhere, and the views expressed in this paper will appear as modest, conservative, and unimaginative as do many of those of Mr. Wells to-day.

I will only touch very briefly on the future of physics, as the subject is inevitably technical. At present physical theory is in a state of profound suspense. This is primarily due to Einstein --- the greatest Jew since Jesus. I have no doubt that Einstein's name will still be remembered and revered when Lloyd George, Foch, and William Hohenzollern share with Charlie Chaplin that ineluctable oblivion which awaits the uncreative mind. I trust that I may be excused if I trespass from the strict subject of my theme to add my quota to the rather numerous misstatements of Einstein's views which have appeared during the last few years.

Ever since the time of Berkeley it has been customary for the majority of metaphysicians to proclaim the ideality of Time, of Space, or of both. But they soon made it clear that in spite of this, time would continue to wait for no man, and space to separate lovers. The only practical consequences that they generally drew was that their own ethical and political views were somehow inherent in the structure of the universe. The experimental proof or disproof of such deductions is difficult, and --- if the late war may be regarded as an experimental disproof of certain of Hegel's political tenets --- costly and unsatisfactory.

Einstein, so far from deducing an new decalogue, has contented himself with deducing the consequences to space and time themselves of their ideality. These are mostly too small to be measurable, but some, such as the deflection of light but the sun's gravitational field, are susceptible of verification, and have been verified. The majority of scientific men are now being constrained by the evidence of these experiments to adopt a very extreme form of Kantian idealism. The Kantian Ding-an-sich is an eternal four-dimensional manifold, which we perceive as space and time, but what we regard as space and what as time is more or less fortuitous.

It is perhaps interesting to speculate on the practical consequences of Einstein's discovery. I do not doubt that he will be believed. A prophet who can give signs in the heavens is always believed. No one ever seriously questioned Newton's theory after the return of Halley's comet. Einstein has told us that space, time and matter are shadows of the fifth dimension, and the heavens have declared his glory. In consequence Kantian idealism will become the basal working hypothesis of the physicist and finally of all educated men, just as materialism did after Newton's day. We may not call ourselves materialists, but we do interpret the activities of the moon, the Thames, influenza, and aeroplanes in terms of matter. Our ancestors did not, nor, in all probability, will our descendants. The materialism (whether conscious or sub-conscious does not matter very much) of the last few generations has led to various results of practical importance, such as sanitation, Marxian socialism, and the right of an accused person to give evidence on his or her own behalf. The reign of Kantian idealism as the basal working hypothesis, first of physics, and then of every-day life, will in all probability last for some centuries. At the end of that time a similar step in advance will be taken. Einstein showed that experience cannot be interpreted in terms of space and time. This was a well-known fact, but so long as space and time down not break down in their own special sphere, that of explaining the facts of motion, physicists continued to believe in them, or at any rate, what was much more important, to think in terms of them for practical purposes.

A time will however come (as I believe) when physiology will invade and destroy mathematical physics, as the latter have destroyed geometry. The basic metaphysical working hypothesis of science and practical life will then, I think, be something like Bergsonian activism. I do not for one moment suggest that this or any other metaphysical system has any claims whatever to finality.

Meanwhile we are in for a few centuries during which many practical activities will probably be conducted on a basis, not of materialism, but of Kantian idealism. How will this affect our manners, morals and politics? Frankly I do not know, though I think the effect will be as great as that of Newton's work, which created most of the intellectual forces of the 18th century. The Condorcets, Benthams, and Marxs of the future will I think be as ruthlessly critical of the metaphysics and ethics of their times as were their predecessors, but not quite so sure of their own; they will lack a certain heaviness of touch which we may note in Utilitarianism and Socialism. They will recognise that perhaps in ethics as in physics, there are so to speak fourth and fifth dimensions that show themselves by effects which, like the perturbations of the planet Mercury, are hard to detect even in one generation, but yet perhaps in the course of ages are quite as important as the three- dimensional phenomena.

If the quantum hypothesis is generally adopted even more radical alterations in our thinking will be necessary. But I feel it premature even to suggest their direction in the present unsatisfactory state of quantum mechanics. It may be that as Poincare (the other Poincare) suggested we shall be forced to conceive of all changes as occurring in a series of clicks, and all space as consisting of discrete points. However this may be it is safe to say that a better knowledge of radiation will permit us to produce it in a more satisfactory manner than is at present possible. Almost all our present sources of light are hot bodies, 95% of whose radiation is invisible. To light a lamp as a source of light is about as wasteful of energy as to burn down one's house to roast one's pork. It is a fairly safe prophecy that in 50 years light will cost about a fiftieth of its present price, and there will be no more night in our cities. The alternation of day and night is a check on the freedom of human activity which must go the way of other spatial and temporal checks. In the long run I think that all that applied physics can do for us is abolish these checks. It enables us to possess more, travel more, and communicate more. I shall not attempt to predict in detail the future developments of transport and communication. They are only limited by the velocity of light. We are working towards a condition when any two persons on earth will be able to be completely present to one another in not more than 1/24 of a second. We shall never reach it, but that is the limit which we shall approach indefinitely. {2}

Developments in this direction are tending to bring mankind more and more together, to render life more and more complex, artificial, and rich in possibilities --- to increase indefinitely man's powers for good and evil.

But there are two prerequisites for all progress of this kind, namely continuous supplies of human and mechanical power. As industries become more and more closely interwoven, so that a dislocation of any one will paralyse a dozen others (and that is the position towards which we are rapidly moving), the ideal of the leaders of industry, under no matter what economic system, will be directed less and less to the indefinite increase of production in the intervals between such dislocations, and more and more to stable and regular production, even at the cost of reduction of profits and output while the industry is proceeding normally. {3} It is quite possible that capitalism itself may demand that the control of certain key industries be handed over completely to the workers in those industries, simply in order to reduce the number of sporadic strikes in them. And as industrial progress continues an ever larger number --- perhaps the majority --- of industries will become key industries. The solution may be entirely different --- we may well see a return to feudalism. But the probability is that the problem will be solved. This view may seem optimistic, but it is more likely than the alternative thesis which may be briefly stated as follows: "No human society will ever succeed in producing a stable organization in which the majority of the population is employed otherwise than in agriculture, animal-rearing, hunting or fishing." It took some thousands of years to produce the stable agricultural society which forms the basis of European life and whose morals we are too apt to regards as eternal truths. It should take a shorter time to evolve a stable industrial society. The people that do so will inherit the earth. In sum, I believe that the progress of science will ultimately make industrial injustice as self- destructive as it is now making international injustice.

As for the supplies of mechanical power, it is axiomatic that the exhaustion of our coal and oil-fields is a matter of centuries only. As it has often been assumed that their exhaustion would lead to the collapse of industrial civilization, I may perhaps be pardoned if I give some of the reasons which lead me to doubt this proposition.

Water-power is not, I think, a probable substitute, on account of its small quantity, seasonal fluctuation, and sporadic distribution. It may perhaps, however, shift the centre of industrial gravity to well-watered mountainous tracts such as the Himalayan foothills, British Columbia, and Armenia. Ultimately we shall have to tap those intermittent but inexhaustible sources of power, the wind and the sunlight. The problem is simply one of storing their energy in a form as convenient as coal or petrol. If a windmill in one's back garden could produce a hundredweight of coal daily (and it can produce its equivalent in energy), our coalmines would be shut down to-morrow. Even to-morrow a cheap, foolproof, and durable storage battery may be invented, which will enable us to transform the intermittent energy of the wind into continuous electric power.

Personally, I think that four hundred years hence the power question in England may be solved somewhat as follows: The country will be covered with rows of metallic windmills working electric motors which in their turn supply current at a very high voltage to great electric mains. At suitable distances, there will be great power stations where during windy weather the surplus power will be used for the electrolytic decomposition of water into oxygen and hydrogen. These gasses will be liquefied, and stored in vast vacuum jacketed reservoirs, probably sunk in the ground. If these reservoirs are sufficiently large, the loss of liquid due to leakage inwards of heat will not be great; thus the proportion evaporating daily from a reservoir 100 yards square by 60 feet deep would not be 1/1000 of that lost from a tank measuring two feet each way. In times of calm, the gasses will be recombined in explosion motors working dynamos which produce electrical energy once more, or more probably in oxidation cells. Liquid hydrogen is weight for weight the most efficient known method of storing energy, as it gives about three times as much heat per pound as petrol. On the other hand it is very light, and bulk for bulk has only one third of the efficiency of petrol. This will not, however, detract from its use in aeroplanes, where weight is more important than bulk. These huge reservoirs of liquified gasses will enable wind energy to be stored, so that it can be expended for industry, transportation, heating and lighting, as desired. The initial costs will be very considerable, but the running expenses less than those of our present system. Among its more obvious advantages will be the fact that energy will be as cheap in one part of the country as another, so that industry will be greatly decentralized; and that no smoke or ash will be produced.

It is on some such lines as these, I think, that the problem will be solved. It is essentially a practical problem, and the exhaustion of our coal- fields will furnish the necessary stimulus for its solution. Even now perhaps Italy might achieve economic independence by the expenditure of a few million pounds upon research on the lines indicated. I may add in parenthesis that, on thermodynamical grounds which I can hardly summarize shortly, I do not much believe in the commercial possibility of induced radio-activity.

Before I turn to the principal part of my subject I should like to consider very briefly the influence on art and literature of our gradual conquest of space and time. I think that the blame for the decay of certain arts rests primarily on the defective education of the artists. An artist must understand his subject matter. At present not a single competent poet and very few painters and etchers outside the Glasgow School understand industrial life, and I believe that there is only one architect of any real originality who understands the possibilities of ferro-concrete. I do not know his name, but he produced in Soissons before the war a market-place with the dignity and daring of an ancient Egyptian temple. If I knew that he had been entrusted with the rebuilding of Soissons, I could not regret its destruction.

Now if we want poets to interpret physical science as Milton and Shelley did (Shelley and Keats were the last English poets who were at all up- to-date in their chemical knowledge), we must see that our possible poets are instructed, as their masters were, in science and economics. I am absolutely convinced that science is vastly more stimulating to the imagination than are the classics {4} , but the products of this stimulus do not normally see the light because scientific men as a class are devoid of any perception of literary form. When they can express themselves we get a Butler or a Norman Douglas. Not until our poets are once more drawn from the educated classes (I speak as a scientist), will they appeal to the average man by showing him the beauty in his own life as Homer and Virgil appealed to the street urchins who scrawled their verses on the walls of Pompeii.

And if we must educate our poets and artists in science, we must educate our masters, labour and capital, in art. Personally I believe that we may have good hopes of both. The capitalist's idea of art in industry at present tends to limit itself to painting green and white stripes on the front of his factories in certain cases. This is a primitive type of decoration, but it has, I think, the root of the matter in it. Before long someone may discover that frescoes inside a factory increase the average efficiency of the worker 1.03% and art will become a commercial proposition once more. Even now it is being discovered that artistic advertising often pays. Similarly I do not doubt that labour will come to find that it cannot live by bread (or shall we say bread and beer) alone. But it can hardly be expected to make this discovery until it is assured of its supply of bread and beer.

Applied chemistry has introduced into human life no radical novelty of the importance of the heat-engine or the telegraph. It has vastly increased the production of various types of substance the most important being metals. But there were explosives, dyes and drugs before chemistry was a science, and its progress along present lines will mainly alter life in a quantitative manner. Perhaps the biggest problems before it in metallurgy are the utilization of low-grade iron ores, and the production of aluminium from clay, which contains up to 24% of that metal. I do not think that even when this is accomplished aluminium will oust iron and steel as they ousted bronze and flint, but it and its alloys will certainly take the second, and possibly the first place as industrial metals. There is just a hope, though I fear little more, that a large-scale production of perfume may form the basis of a re-education of our rather rudimentary sense of smell, but the most interesting possibilities of chemical invention are very clearly in biological chemistry, and for the following reasons.

Desirable substances fall on the whole into two classes. The first are desirable on account of their physical or chemical properties, for example iron, wood or glass, which we use as a part of systems such as fires, houses or razors, which procure us certain benefits. The second are desirable on account of their physiological properties. Such substances include foods, drinks, tobacco and drugs. Colours and scents occupy an intermediate position. The value of this second class of substances rests on a quite special relationship to the human organism which depends in the most intimate way on the constitution of the latter, and has not in general been at all fully explained in terms of physics and chemistry. For example fires can be made of coal or peat instead of wood, but no other chemical substance has the same effect as water or alcohol. So unless a chemical substance has new physiological properties its production will merely serve to improve or make possible some appliance whose use lies within the sphere of applied physics. Within historical time two and only two substances of the second class have come into universal use in Europe, namely caffeine and nicotine, which were introduced into this country in the sixteenth and seventeenth centuries. There are others of immense importance, such as chloroform and quinine, but their use is not universal. But coffee, tea, and tobacco, with alcohol, are as much a part of normal life as food and water. There is no reason to suppose that the list of such substances is exhausted. During the war Embden {5} the professor of physiology in Frankfurt University discovered that a dose of about 7 grams of acid sodium phosphate increased a man's capacity for prolonged muscular work by about 20% and probably aids in prolonged mental work. It can be taken over very lengthy periods. A group of coal-miners took it for nine months on end with very great effects on their output. It has no after-effects like those of alcohol, and one cannot take a serious overdose as it merely acts as a purgative. (they gave certain Stosstruppen too much!) Thousands of people in Germany take it habitually. It is possible that it may become as normal a beverage as coffee or tea. It costs 1/9 per pound, or 1/3d. per dose.

The vast majority of chemical substances with physiological properties are unsuited for daily use like castor oil, or dangerous like morphine; probably none are without bad effects in certain cases. Those which are susceptible of daily use are of the utmost social importance. Tobacco has slight but definite effects on the character. Coffee-houses in London in the seventeenth and eighteenth centuries and cafes in modern Europe were and are civilizing influences of incalculable value. But these substances are profoundly obnoxious to a certain type of mind. It would perhaps be fantastic to suggest that Sir Walter Raleigh owed his death in part to his sovereign's objection to tobacco. But if he is not its proto-martyr it is at least probable that more have died for tobacco smoking at the hands of Sikhs, Senussis, and Wahabis, whose religions forbid this practice, than died under the Roman empire for professing Christianity. Should it ever be generally realised that temperance is a mean we may expect that mankind will ultimately have at its disposal a vast array of substances like wine, coffee and tobacco, whose intelligent use can add to the amenity of life and promote the expression of man's higher faculties.

But before that day comes chemistry will be applied to the production of a still more important group of physiologically active substances, namely foods. The facts about food are rather curious. Everyone knows that food is ultimately produced by plants, though we may get it at second or third hand if we eat animals or their products. But the average plant turns most of its sugar not into starch which is digestible, but into cellulose which is not, but forms its woody skeleton. The hoofed animals have dealt with this problem in their own way, by turning their bellies into vast hives of bacteria that attack cellulose, and on whose by-products they live. We have got to do the same, but outside our bodies. It may be done on chemical lines. Irvine has obtained a 95% yield of sugar from cellulose, but at a prohibitive cost. Or we may use micro-organisms, but in any case within the next century sugar and starch will be about as cheap as sawdust. Many of our foodstuffs, including the proteins, we shall probably build up from simpler sources such as coal and atmospheric nitrogen. I should be inclined to allow 120 years, but not much more, before a completely satisfactory diet can be produced in this way on a commercial scale.

This will mean that agriculture will become a luxury, and that mankind will be completely urbanized. Personally I do not regret the probable disappearance of the agricultural labourer in favour of the factory worker, who seems to me a higher type of person from most points of view. Human progress in historical time has been the progress of cities dragging a reluctant countryside in their wake. Synthetic food will substitute the flower garden and the factory for the dunghill and the slaughterhouse, and make the city at last self-sufficient.

There's many a strong farmer whose heart would break in two
If he could see the townland that we are riding to.
Boughs have their fruit and blossom at all times of the year,
Rivers are running over with red beer and brown beer,
An old man plays the bagpipes in a golden and silver wood,
Queens, their eyes blue like the ice, are dancing in a crowd.

I should have like had time allowed to have added my quota to the speculations which have been made with regard to inter-planetary communication. Whether this is possible I can form no conjecture; that it will be attempted I have no doubt whatever.

With regard to the application of biology to human life, the average prophet appears to content himself with considerable if rather rudimentary progress in medicine and surgery, some improvements in domestic plants and animals, and possibly the introduction of a little eugenics. The eugenic official, a compound, it would appear, of the policeman, the priest and the procurer, is to hale us off at suitable intervals to the local temple of Venus Genetrix with a partner chosen, one gathers, by something of a glorified medical board. To this prophecy I should reply that it proceeds from a type of mind as lacking in originality as in knowledge of human nature. Marriage "by numbers", so to speak, was a comparatively novel idea when proposed by Plato 2,300 years ago, but it has already actually been practised in various places, notably among the subject of the Jesuits in Paraguay. It is moreover likely, as we shall see, that the ends proposed by the eugenist will be attained in a very different manner.

But before we proceed to prophecy I should like to turn back to the past and examine very briefly the half dozen or so important biological inventions which have already been made. By a biological invention I mean the establishment of a new relationship between man and other animals or plants, or between different human beings, provided that such relationship is one which comes primarily under the domain of biology rather than physics, psychology or ethics. Of the biological inventions of the past, four were made before the dawn of history. I refer to the domestication of animals, the domestication of plants, the domestication of fungi for the production of alcohol, and to a fourth invention, which I believe was of more ultimate and far-reaching importance than any of these, since it altered the path of sexual selection, focussed the attention of man as a lover upon woman's face and breasts, and changed our idea of beauty from the steatapygous Hottentot to the modern European, from the Venus of Brassempouy to the Venus of Milo. There are certain races which have not yet made this last invention. And in our own day two more have been made, namely bactericide and the artificial control of conception.

The first point that we may notice about these inventions is that they have all had a profound emotional and ethical effect. Of the four earlier there is not one which has not formed the basis of a religion. I do not know what strange god will have the hardihood to adopt Charles Bradlaugh and Annie Besant in the place of Triptolemus and Noah, but one may remark that it is impossible to keep religion out of any discussion of the practices which they popularized.

The second point is perhaps harder to express. The chemical or physical inventor is always a Prometheus. There is no great invention, from fire to flying, which has not been hailed as an insult to some god. But if every physical and chemical invention is a blasphemy, every biological invention is a perversion. There is hardly one which, on first being brought to the notice of an observer from any nation which has not previously heard of their existence, would not appear to him as indecent and unnatural.

Consider so simple and time-honored a process as the milking of a cow. The milk which should have been an intimate and almost sacramental bond between mother and child is elicited by the deft fingers of a milk-maid, and drunk, cooked, or even allowed to rot into cheese. We have only to imagine ourselves as drinking any of its other secretions, in order to realise the radical indecency of our relation to the cow. {6}

No less disgusting a priori is the process of corruption which yields our wine and beer. But in actual fact the process of milking and of the making and drinking of beer appear to us profoundly natural; they have even tended to develop a ritual of their own whose infraction nowadays has a certain air of impropriety. There is something slightly disgusting in the idea of milking a cow electrically or drinking beer out of tea-cups. And all this of course applies much more strongly to the sexual act.

I fancy that the sentimental interest attaching to Prometheus has unduly distracted our attention from the far more interesting figure of Daedalus. It is with infinite relief that amidst a welter of heroes armed with gorgon's heads or protected by Stygian baptisms the student of Greek mythology comes across the first modern man. Beginning as a realistic sculptor (he was the first to produce statues whose feet were separated) it was natural that he should proceed to the construction of an image of Aphrodite whose limbs were activated by quicksilver. After this his interest inevitably turned to biological problems, and it is safe to say that posterity has never equaled is only recorded success in experimental genetics. Had the housing and feeding of the Minotaur been less expensive it is probable that Daedalus would have anticipated Mendel. But Minos held that a labyrinth and an annual provision of 50 youths and 50 virgins were excessive as an endowment for research, and in order to escape from his ruthless economies Daedalus was forced to invent the art of flying. Minos pursued him to Sicily and was slain there. Save for his valuable invention of glue, little else is known of Daedalus. But it is most significant that, although he was responsible for the death of Zeus' son Minos he was neither smitten by a thunderbolt, chained to a rock, nor pursued by furies. Still less did any of the rather numerous visitors to Hades discover him either in Elysium or Tartarus. We can hardly imagine him as a member of the throng of shades who besieged Charon's ferry like sheep at a gap. He was the first to demonstrate that the scientific worker is not concerned with gods.

The unconscious mind of the early Greeks, who focussed in this amazing figure the dim traditions of Minoan science, was presumably aware of this fact. The most monstrous and unnatural action in all human legend was unpunished in this world or the next. Even the death of Icarus must have weighed lightly with a man who had already been banished from Athens for the murder of his nephew. But if he escaped the vengeance of the gods he has been exposed to the universal and agelong reprobation of a humanity to whom biological inventions are abhorrent, with one very significant exception. Socrates was proud to claim him as an ancestor.

The biological invention then tends to begin as a perversion and end as a ritual supported by unquestioned beliefs and prejudices. Even now surgical cleanliness is developing its rites and its dogmas, which, it may be remarked, are accepted most religiously by women. With the above facts in your minds I would ask you to excuse what at first sight might appear improbable or indecent in any speculations which appear below, and to dismiss from your minds the belief that biology will consist merely and physical and chemical discoveries as applied to men, animals and plants.

I say advisedly "will consist", for we are at present almost completely ignorant of biology, a fact which often escapes the notice of biologists, and renders them to presumptuous in their estimates of the present position of their science, too modest in their claims for its future. If for example we take a typical case of applied biology such as the detection and destruction of the cholera bacillus, we find a great deal of science involved, but the only purely biological principle s the very important but not very profound one that some bacteria kill some men. The really scientific parts of the process are the optical and chemical methods involved in the magnification, staining and killing of the bacilli. When on the other hand we come to immunization to typhoid we find certain purely biological principles involved which are neither simple nor at all completely understood.

Actually biological theory consists of some ancient but not very easily stated truths about organisms in general, due largely to Aristotle, Hippocrates and Harvey, a few great principles such as those formulated by Darwin, Mayer, Claude Bernard, and Mendel, and a vast mass of facts about individual organisms and their parts which are still awaiting adequate generalization.

Darwin's results are beginning to be appreciated, with alarming effects on certain types of religion, those of Weismann and Mendel will be digested in the course of the present century, and are going to affect political and philosophical theories almost equally profoundly. I need hardly say that these latter results deal with the question of reproduction and heredity. We may expect, moreover, as time goes on, that a series of shocks of the type of Darwinism will be given to established opinions on all sorts of subjects. One cannot suggest in detail what these shocks will be, but since the opinions on which they will impinge are deep-seated and irrational, they will come upon us and our descendants with the same air of presumption and indecency with which the view that we are descended from monkeys came to our grandfathers. But owing to man's fortunate capacity for thinking in watertight (or rather idea-tight) compartments, they will probably not have immediate and disruptive effects upon society any more than Darwinism had.

Far more profound will be the effect of the practical applications of biology. I believe that the progress of medicine has had almost, if not quite, as deep an effect on society in Western Europe as the industrial revolution. Apart from the important social consequences which have flowed from the partial substitution of the doctor for the priest, its net result has been that whereas four hundred years ago most people died in childhood, they now live on an average, (apart from the late war), until forty-five. Bad as our urban conditions are, there is not a slum in the country which has a third of the infantile death-rates of the royal family in the middle ages. Largely as a result of this religion has come to lay less and less stress on a good death, and more and more on a good life, and its whole outlook has gradually changed in consequence. Death has receded so far into the background of our normal thoughts that when we came into somewhat close contact with it during the war most of us failed to take it seriously.

Similarly institutions which were based on short lives have almost wholly collapsed. For example the English land system postulated that the land- owner should die aged about forty, and be succeeded by his eldest son, aged about twenty. The son had spent most of his life on the estate, and had few interests outside it. He managed it at least as well as anyone else could have done. Nowadays the father dodders on till about eighty, and is generally incompetent for ten years before his death. His son succeeds him at the age of fifty or so, by which time he may be a fairly competent colonel or stockbroker, but cannot hope to learn the art of managing an estate. In consequence he either hands it over to an agent who is often corrupt, or runs it unscientifically, gets a low return, and ascribes to Bolshevism what he should really lay at the door of vaccination.

But to return, if I may use the expression, to the future, I am going to suggest a few obvious developments which seem probable in the present state of biological science, without assuming any great new generalizations of the type of Darwinism. I have the very best precedents for introducing a myth at this point, so perhaps I may be excused if I reproduce some extracts from an essay on the influence of biology on history during the 20th century which will (it is hoped) be read by a rather stupid undergraduate member of this university to his supervisor during his first term 150 years hence.

``As early as the first decade of the twentieth century we find a conscious attempt at the application of biology to politics in the so-called eugenic movement. A number of earnest persons, having discovered the existence of biology, attempted to apply it in its then very crude condition to the production of a race of super-men, and in certain countries managed to carry a good deal of legislation. They appear to have managed to prevent the transmission of a good deal of syphilis, insanity, and the like, and they certainly succeeded in producing the most violent opposition and hatred amongst the classes whom they somewhat gratuitously regarded as undesirable parents. (There was even a rebellion in Nebraska). However, they undoubtably prepared public opinion for what was to come, and so far served a useful purpose. Far more important was the progress in medicine which practically abolished infectious diseases in those countries which were prepared to tolerate the requisite amount of state interference in private life, and finally, after the league's {7} ordinance of 1958, all over the world; though owing to Hindu opposition, parts of India were still quite unhealthy up to 1980 or so.

But from a wider point of view the most important biological work in the first third of the century was in experimental zoology and botany. When we consider that in 1912 Morgan had located several Mendelian factors in the nucleus of Drosophila, and modified its sex-ratio, while Marmorek had taught a harmless bacillus to kill guinea-pigs, and finally in 1913 Brachet had grown rabbit embryos in serum for some days, it is remarkable how little the scientific workers of that time, and a fortiori the general public, seem to have foreseen the practical bearing of such results.

As a matter of fact it was not until 1940 that Selkovski invented the purple alga Porphyrococcus fixator which was to have so great an effect on the world's history. In the 50 years before this date the world's average wheat yield per hectare had been approximately doubled, partly by the application of various chemical manures, but most of all by the results of systematic crossing work with different races; there was however little prospect of further advance on any of these lines. Porphyrococcus is an enormously efficient nitrogen-fixer and will grow in almost any climate where there are water and traces of potash and phosphates in the soil, obtaining its nitrogen from the air. It has about the effect in four days that a crop of vetches would have had in a year. It could not, of course, have been produced in the course of nature, as its immediate ancestors would only grow in artificial media and could not have survived outside a laboratory. Wherever nitrogen was the principal limiting factor to plant growth it doubled the yield of wheat, and quadrupled the value of grass land for grazing purposes. The enormous fall in food prices and the ruin of purely agricultural states was of course one of the chief causes of the disastrous events of 1943 and 1944. The food glut was also greatly accentuated when in 1942 the Q strain of Porphyrococcus escaped into the sea and multiplied with enormous rapidity. Indeed for two months the surface of the tropical Atlantic set to a jelly, with disastrous results to the weather of Europe. When certain of the plankton organisms developed ferments capable of digesting it the increase of the fish population of the seas was so great as to make fish the universal food that it is now, and to render even England self-supporting in respect of food. So great was the prosperity in England that in that year the coal-miner's union entered its first horse for the Derby (a horse-race which still took place annually at that time).

It was of course as a result of its invasion by Porphyrococcus that the sea assumed the intense purple colour which seems so natural to us, but which so distressed the more aesthetically minded of our great grand- parents who witnessed the change. It is certainly curious to us to read of the sea as having been green or blue. I need not detail the work of Ferguson and Rahmatullah who in 1957 produced the lichen which has bound the drifting sand of the world's deserts (for it was merely a continuation of that of Selkovski), nor yet the story of how the agricultural countries dealt with their unemployment by huge socialistic windpower schemes.

It was in 1951 that Dupont and Schwarz produced the first ectogenetic child. As early as 1901 Heape had transferred embryo rabbits from one female to another, in 1925 Haldane had grown embryonic rats in serum for ten days, but had failed to carry the process to its conclusion, and it was not till 1946 that Clark succeeded with the pig, using Kehlmann's solution as medium. Dupont and Schwarz obtained a fresh ovary from a woman who was the victim of an aeroplane accident, and kept it living in their medium for five years. They obtained several eggs from it and fertilized them successfully, but the problem of nutrition and support of the embryo was more difficult, and was only solved in the fourth year. Now that the technique is fully developed, we can take an ovary from a woman, and keep it growing in a suitable fluid for as long as twenty years, producing a fresh ovum each month, of which 90 per cent can be fertilized, and the embryos grown successfully for nine months, and then brought out into the air. Schwarz never got such good results, but the news of his first success caused an unprecedented sensation throughout the entire world, for the birthrate was already less than the death rate in most civilised countries. France was the first country to adopt ectogenesis officially, and by 1968 was producing 60,000 children annually by this method. In most countries the opposition was far stronger, and was intensified by the Papal Bull ``Nunquam prius audito'', and by the similar fetwa of the Khalif, both of which appeared in 1960.

As we know ectogenesis is now universal, and in this country less than 30 per cent of children are now born of woman. The effect on human psychology and social life of the separation of sexual love and reproduction which was begun in the 19th century and completed in the 20th is by no means wholly satisfactory. The old family life had certainly a good deal to commend it, and although nowadays we bring on lactation in women by injection of placentin as a routine, and thus conserve much of what was best in the former instinctive cycle, we must admit that in certain respects our great grandparents had the advantage of us. On the other hand it is generally admitted that the effects of selection have more than counterbalanced these evils. The small proportion of men and women who are selected as ancestors for the next generation are so undoubtedly superior to the average that the advance in each generation in any single respect, from the increased output of first-class music to the decreased convictions for theft, is very startling. {8} Had it not been for ectogenesis there can be little doubt that civilisation would have collapsed within a measurable time owing to the greater fertility of the less desirable members of the population in almost all countries.

It is perhaps fortunate that the process of becoming an ectogenetic mother of the next generation involves an operation which is somewhat unpleasant, though now no longer disfiguring or dangerous, and never physiologically injurious, and is therefore an honour but by no means a pleasure. Had this not been the case, it is perfectly possible that popular opposition would have proved too strong for the selectionist movement. As it was the opposition was very fierce, and characteristically enough this country only adopted its present rather stringent standard of selection a generation late than Germany, though it is now perhaps more advanced than any other country in this respect. The advantages of thorough-going selection, have, however, proved to be enormous. The question of the ideal sex ratio is still a matter of violent discussion, but the modern reaction towards equality is certainly strong.''

Our essayist would then perhaps go on to discuss some far more radical advances made about 1990, but I have only quoted his account of the earlier applications of biology. The second appears to me to be neither impossible nor improbable, but it has those features which we saw above to be characteristic of biological inventions. If reproduction is once completely separated from sexual love mankind will be free in an altogether new sense. At present the national character is changing slowly according to quite unknown laws. The problem of politics is to find institutions suitable to it. In the future perhaps it may be possible by selective breeding to change character as quickly as institutions. I can foresee the election placards of 300 years hence, if such quaint political methods survive, which is perhaps improbable, ``Vote for Smith and more musicians'', ``Vote for O'Leary and more girls'', or perhaps finally ``Vote for Macpherson and a prehensile tail for your great-grandchildren''. We can already alter animal species to an enormous extent, and it seems only a question of time before we shall be able to apply the same principles to our own.

I suggest then that biology will probably be applied on lines roughly resembling the above. There are perhaps equally great possibilities in the way of direct improvement of the individual, as we come to know more of the physiological obstacles to the development of different faculties. But at present we can only guess at the nature of these obstacles, and the line of attack suggested in the myth is the one which seems most obvious to a Darwinian. We already know however that many of our spiritual faculties can only be manifested if certain glands, notably the thyroid and sex-glands, are functioning properly, and that very minute changes in such glands affect the character greatly. As our knowledge of this subject increases we may be able, for example, to control our passions by some more direct method than fasting and flagellation, to stimulate our imagination by some reagent with less after- effects than alcohol, to deal with perverted instincts by physiology rather than prison. Conversely there will inevitably arise possibilities of new vices similar to but even more profound than those opened up by the *SPAM* discoveries of the 19th century.

The recent history of medicine is as follows. Until about 1870 medicine was largely founded on physiology, or, as the Scotch called it ``Institutes of medicine''. Disease was looked at from the point of view of the patient, as injuries still are. Pasteur's discovery of the nature of infectious disease transformed the whole outlook, and made it possible to abolish one group of diseases. But it also diverted scientific medicine from its former path, and it is probable that, were bacteria unknown, though many more people would die of sepsis and typhoid, we should be better able to cope with kidney disease and cancer. Certain diseases such as cancer are probably not due to specific organisms, whilst others such as phthisis are due to forms which are fairly harmless to the average person, but attack others for unknown reasons. We are not likely to deal with them effectually on Pasteur's lines, we must divert our view from the micro-organism to the patient. Where the doctor cannot deal with the former he can often keep the patient alive long enough to be able to do so himself. And here he has to rely largely on a knowledge of physiology. I do not say that a physiologist will discover how to prevent cancer. Pasteur started life as a crystallographer. But whoever does so is likely at least to make use of physiological data on a large scale.

The abolition of disease will make death a physiological event like sleep. A generation that has lived together will die together. I suspect that man's desire for a future life is largely due to two causes, a feeling that most lives are incomplete, and a desire to meet friends from whom we have parted prematurely. A gentle decline into the grave at the end of a completed life's work will largely do away with the first, and our contemporaries will rarely leave us sorrowing for long.

Old age is perhaps harder on women than on men. They live longer, but their life is too often marred by the sudden change which generally overtakes them between forty and fifty, and sometimes leaves them a prey to disease, though it may improve their health. This change seems to be due to a sudden failure of a definite chemical substance produced by the ovary. When we can isolate and synthesize this body we shall be able to prolong a woman's youth, and allow her to age as gradually as the average man.

Psychology is hardly a science yet. Like biology it has arrived at certain generalizations of a rather abstract and philosophic character, but these are still to some extent matters of controversy. And though a vast number of most important empirical facts are known, only a few great generalizations from them --- such as the existence of the subconscious mind --- have yet been made. But anyone who has seen even a single example of the power of hypnotism and suggestion must realise that the face of the world and the possibilities of existence will be totally altered when we can control their effects and standardize their application, as has been possible, for example, with drugs which were once regarded as equally magical. Infinitely greater, of course, would be the results of the opening up of systematic communication with spiritual beings in another world, which is claimed as a scientific possibility. Spiritualism is already Christianity's most formidable enemy, and we have no data which allow us to estimate the probable effect on man of a religion whose dogmas are matters of experiment, whose mysteries are prosaic as electric lighting, whose ethics are based on the observed results in the next world of a good or bad life in this. Yet that is the prospect before us if spiritualism obtains the scientific verification which it is now demanding, not perhaps with great success.

I have only been able, in the time at my disposal, to traverse a very few of the possible fields of scientific advance. If I have convinced anyone present that science has still a good deal up her sleeve, and that of sufficiently startling character, I shall be amply repaid. If anything I have said appears to be of a gratuitously disgusting nature, I would reply that certain phenomena of normal life do seem to many to be of that nature, and that these phenomena are of the utmost scientific and practical importance.

I have tried to show why I believe that the biologist is the most romantic figure on earth at the present day. At first sight he seems to be just a poor little scrubby underpaid man, groping blindly amid the mazes of the ultra-microscopic, engaging in bitter and lifelong quarrels over the nephridia of flatworms, waking perhaps one morning to find that someone whose name he has never heard has demolished by a few crucial experiments the work which he had hoped would render him immortal. There is real tragedy in his life, but he knows that he has a responsibility which he dare not disclaim, and he is urged on, apart from all utilitarian considerations, by something or someone which he feels to be higher than himself.

The conservative has but little to fear from the man whose reason is the servant of his passions, but let him beware of him in whom reason has become the greatest and most terrible of the passions. These are the wreckers of outworn empires and civilisations, doubters, disintegrators, deicides {9} . In the past they have been, in general, men like Voltaire, Bentham, Thales, Marx, and very possibly the divine Julius {10} , but I think that Darwin furnishes an example of the same relentlessness of reason in the field of science. I suspect that as it becomes clear that at present reason not only has a freer play in science than elsewhere, but can produce as great effects on the world through science as through politics, philosophy, or literature, there will be more Darwins. Such men are interested primarily in truth as such, but they can hardly be quite uninterested in what will happen when they throw down their dragon's teeth into the world.

I do not say that biologists as a general rule try to imagine in any detail the future applications of their science. The central problems of life for them may be the relationship between the echinoderms and the brachiopods, and the attempt to live on their salaries. They do not see themselves as sinister and revolutionary figures. They have no time to dream. But I suspect that more of them dream than would care to confess it.

I have given above a very small selection from my dreams. Perhaps they are bad dreams. It is of course almost hopeless to attempt any very exact prophecies as to how in detail scientific knowledge is going to revolutionize human life, but I believe that it will continue to do so, and even more profoundly than I have suggested. And though personally I am Victorian enough in my sympathies to hope that after all family life, for example, may be spared, I can only reiterate that not one of the practical advances which I have predicted is not already foreshadowed by recent scientific work. If a chemist or physicist living at the end of the seventeenth century had been asked to predict the future application of his science he would doubtless have made many laughable errors in the best Laputan style, but he would have been certain that it would somehow be applied, and his faith would have been justified.

We must regard science then from three points of view. First it is the free activity of man's divine faculties of reason and imagination. Secondly it is the answer of the few to the demands of the many for wealth, comfort and victory, for {Here Haldane quots a Greek phrase I cannot reproduce in ASCII}, gifts which it will grant only in exchange for peace, security and stagnation. Finally it is man's gradual conquest, first of space and time, then of matter as such, then of his own body and those of other living beings, and finally the subjugation of the dark and evil elements in his own soul.

None of these conquests will ever be complete but all, I believe will be progressive. The question of what he will do with these powers is essentially a question for religion and aesthetic. It may be urged that they are only fit to be placed in the hands of a being who has learned to control himself, and that man armed with science is like a baby armed with a box of matches.

The answer to this contention may, I think, be found in the daily papers. For scores of centuries idealists had urged that wars must cease and all the earth be united under one rule. As long as any other alternative was possible it was persisted in. The events of the last nine years constituted a reductio ad absurdum of war, but when we ask who responsible for this we shall find that it was not the visionaries but men like Black, Kekule, and Langley, who enlarged man's power over nature until he was forced by the inexorable logic of facts to form the nucleus of an international government.

We have already reacted against the frame of mind that engendered the league of nations, but we have not reacted at all completely. The league exists and is working, and in every country on earth there are many people, and ordinary normal people, who favor the idea in one form or another of a world state. I do not suggest that a world-state will arise from the present league --- or for the matter of that from the third international. I merely observe that there is a widespread and organized desire for such an institution, and several possible nuclei for it. It may take another world-war or two to convert the majority. The prospect of the next world-war has at least this satisfactory element. In the late war the most rabid nationalists were to be found well behind the front line. In the next war no one will be behind the front line. It will be brought home to all whom it may concern that war is a very dirty business.

No doubt there is a fair chance that the possibility of human organization on a planetary scale may be rendered impossible by such a war. If so mankind will probably have to wait for a couple of thousand years for another opportunity. But to the student of geology such a period is negligible. It took man 250,000 years to transcend the hunting pack. It will not take him so long to transcend the nation.

I think then that the tendency of applied science is to magnify injustices until they become too intolerable to be borne, and the average man whom all the prophets and poets could not move, turns at least and extinguishes the evil at its source. Marx' theory of industrial evolution is a particular example of this tendency, though it does not in the least follow that his somewhat artificial solution of the problem will be adopted.

It is probable that biological progress will prove to be as incompatible with certain of our social evils as industrial progress has proved to be with war or certain systems of private ownership. To take a concrete example it is clear that the second biological invention considered by my future essayist would be intolerable in conjunction with our present system of relations between classes and sexes. Moral progress is so difficult that I think any developments are to be welcomed which present it as the naked alternative to destruction, no matter how horrible may be the stimulus which is necessary before man will take the moral step in question.

To sum up, then, science is as yet in its infancy, and we can foretell little of the future save that the thing that has not been is the thing that shall be; that no beliefs, no values, no institutions are safe. So far from being an isolated phenomenon the late war is only an example of the disruptive result that we may constantly expect from the progress of science. The future will be no primrose path. It will have its own problems. Some will be the secular problems of the past, giant flowers of evil blossoming at last to their own destruction. Others will be wholly new. Whether in the end man will survive his ascensions of power we cannot tell. But the problem is no new one. It is the old paradox of freedom re-enacted with mankind for actor and the earth for stage. To those who believe in the divinity of that part of man which aspires after knowledge for its own sake, who are, in the words of Boethius:

te cernere finis
Principum, vector, dux, semita, terminus idem

the prospect will appear most hopeful. But it is only hopeful if mankind can adjust its morality to its powers. If we can succeed in this, then science holds in her hands one at least of the keys to the thorny and arduous path of moral progress, then:

Per cruciamina leti
Via panditur ardua justis,
Et ad astra doloribus itur.

That is possibly a correct large-scale view, but it is only for short periods that one can take views of history sufficiently broad to render the fate of one's own generation irrelevant. The scientific worker is brought up with the moral values of his neighbors. He is perhaps fortunate if he does not realize that it is his destiny to turn good into evil. The moral and physical (though not the intellectual) virtues are means between two extremes. They are essentially quantitative. It follows that an alteration in the scale of human power will render actions bad which were formerly good. Our increased knowledge of hygiene has transformed resignation and inaction in face of epidemic disease from a religious virtue to a justly punishable offence. We have improved our armaments, and patriotism, which was once a flame upon the altar, has become a world-devouring conflagration.

The time has gone by when a Huxley could believe that while science might indeed remould traditional mythology, traditional morals were impregnable and sacrosanct to it. We must learn not to take traditional morals too seriously. And it is just because even the least dogmatic of religions tends to associate itself with some kind of unalterable moral tradition, that there can be no truce between science and religion.

There does not seem to be any particular reason why a religion should not arise with an ethic as fluid as Hindu mythology, but it has not yet arisen. Christianity has probably the most flexible morals of any religion, because Jesus left no code of law behind him like Moses or Muhammad, and his moral precepts are so different from those of ordinary life that no society has ever made any serious attempt to carry them out, such as was possible in the case of Israel and Islam. But every Christian church has tried to impose a code of morals of some kind for which it has claimed divine sanction. As these codes have always been opposed to those of the gospels a loophole has been left for moral progress such as hardly exists in other religions. This is no doubt an argument for Christianity as against other religions, but not as against none at all, or as against a religion which will frankly admit that its mythology and morals are provisional. That is the only sort of religion that would satisfy the scientific mind, and it is very doubtful whether it could properly be called a religion at all.

No doubt many people hope that such a religion may develop from Christianity. The human intellect is feeble, and there are times when it does not assert the infinity of its claims. But even then:

Though in black jest it bows and nods
* * * *
I know it is roaring at the gods
Waiting for the last eclipse.

The scientific worker of the future will more and more resemble the lonely figure of Daedalus as he becomes conscious of his ghastly mission, and proud of it.

Black is his robe from top to toe,
His flesh is white and warm below,
All through his silent veins flow free
Hunger and thirst and venery,
But in his eyes a still small flame
Like the first cell from which he came
Burns round and luminous, as he rides
Singing my song of deicides.

6: The Hindus have recognized the special and physiological relation of man to the cow by making the latter animal holy. A good Hindu would no more kill a cow than his foster-mother. But the holiness of the cow has unfortunately extend to all its products, and the extensive use of cow dung in Indian religious ceremonies is disgusting to the average European. The latter, however, is insensitive to the equally loathsome injunctions of the Catholic Church with regard to human marriage. It would perhaps be better if both marriage and milking could be secularized. [Haldane's note.]

LITTLE DOTS

A STUDY OF THE MELODIES OF THE GUITARIST/COMPOSER FRANK ZAPPA

By

Brett Clement


A thesis submitted to the School of Music In partial fulfillment of the Requirements for the degree of Master of Music

Degree Awarded: Spring Semester, 2004


(...)

ABSTRACT

This study explores the pitch and rhythmic content of the melodies
of Frank Zappa. It also describes the relationship between Zappa’s
melodies and their harmonic climates. Three pieces are analyzed in detail.
The analysis of the guitar solo “Pink Napkins” serves to introduce Zappa’s
theory of harmonic climates. A system is devised to explore consonance
and dissonance relationships in the solo. The analysis of “The Black Page”
explicates Zappa’s use of “rhythmic dissonance” by means of the
relationship between a melody and its “factory-cycle” pulse. Comparisons
are made between “Pink Napkins” and “The Black Page” in order to
describe the free exchange between Zappa’s improvisations and his
composed melodies. Finally, the analysis of “Be-Bop Tango” engages
Zappa’s atonal process and describes the structural importance of long-held
notes in the piece. Other aesthetic concerns in the music of Frank Zappa
are addressed.

Why we ALL have psychic powers: How thought premonitions and telepathy are more common than we think

By Dr Rupert Sheldrake


Like many mothers who feared for their family’s safety during World War II, Mona Miller was evacuated from London to the peaceful seaside town of Babbacombe in Devon.

It seemed like a wise precaution but, shortly after her arrival there with her young children, Mrs Miller became increasingly uneasy.

‘I had a feeling that I must leave Devon and return home,’ she told me.

‘At first I dismissed the idea; why leave when I was so happy and contented despite the war going on around me?

‘But the feeling increased. The walls of my room seemed to speak to me: “Go home to London.” I resisted the call for about four months then, one day, like a flash of light, I knew we must leave.

‘On a Saturday in late 1942, we travelled back to London and a few days later I received a letter from a friend in Devon.

‘“Thank God you took the children on Saturday,” she wrote. “Early Sunday morning, Jerry dropped three bombs and one fell on the house where you were living, demolishing it, and killing all the neighbours on either side.”’

Mrs Miller was far from the only person to experience such forebodings during the war.
Three years later, in the spring of 1945, U.S. serviceman Charles Bernuth took part in the invasion of Germany and, shortly after crossing the Rhine, found himself driving along the autobahn one night with two officers.

He described how a ‘still, small voice’ within him told him there was something wrong with the road ahead.

‘I stopped, amid the groans and jeers of the other two. I started walking along the road.

‘About 50 yards from where I had left the jeep, I found out what was wrong.

'We were about to go over a bridge — only the bridge wasn’t there. It had been blown up and there was a sheer drop of about 75ft.’

Both Mrs Miller and Charles Bernuth had experienced presentiments — feelings that something was going to happen without knowing what it would be.

These differ from premonitions, where the person involved has an insight into what lies ahead, as when 16-year-old Carole Davies visited a London amusement arcade during the Seventies.

‘While standing looking out into the night, I had a sense of danger,’ she recalled.

‘Then I saw what looked like a picture in front of me showing people on the floor with tiles and metal girders on them. I realised that this was to happen here. I began to shout at people to get out. No one listened.’

Together with her friends, Carole hurried out and went to a nearby cafe.

As they sat inside, they heard sirens in the street outside. A weakness in the arcade building’s structure had brought its roof and walls crashing down on those within.

‘We all ran down the road to see what had happened,’ Carole remembered.

‘It was just as I had seen. A man I had shouted at was being pulled from under the debris.’
Like Mona Miller and Charles Bernuth before her, Carole was convinced she owed her life to her mysterious sixth sense, a notion which you might expect a scientist of my background to dismiss out of hand.

I am a biologist who has studied, researched and taught at both Cambridge and Harvard, and held senior academic posts on both sides of the Atlantic.

Yet I’ve long believed that presentiments, premonitions and other psychic phenomena such as telepathy should be taken more seriously by my scientific colleagues.

My fascination with this subject began during the Sixties when I was a graduate student in the biochemistry department at Cambridge University.

This was not long after the South African writer Laurens van der Post had published his accounts of life with the Bushmen of the Kalahari desert.

Like most traditional societies, theirs was one in which telepathy was not only taken for granted, but put to practical use, as van der Post saw when his hosts hunted down and killed an eland antelope many miles from camp.

As they were driving back in a Land Rover laden with meat, he asked one of the Bushmen how those back at camp would react when they learned of this success.

‘They already know — we Bushmen have a wire here,’ he replied, tapping his chest. ‘It brings us news.’

He was comparing their method of communication with the white man’s telegram or ‘wire’.

Sure enough, when they approached the camp, the people were singing the ‘Eland Song’ and preparing to give the hunters the greatest of welcomes.

Many other travellers in Africa have reported that people seemed to know when loved ones were coming home.

The same would occur in rural Norway, where the inhabitants developed a special word — vardoger — for the anticipation of arrivals.

Similarly, accounts I read of the ‘second sight’ of some inhabitants of the Scottish Highlands included visions of arrivals before the person in question appeared.

But none of this convinced me, converted as I was to the dogma of ‘materialism’ which has dominated scientific thought since the late 19th century, and still does so today.

According to materialists, science will eventually explain everything in terms of physics and chemistry.

And anything that cannot be thus explained can be dismissed as illusory.

Educated in this tradition, I adopted the standard dismissive attitude when the subject of telepathy came up in the laboratory tearoom one day.

I was gently taken to task by Sir Rudolph Peters, one of the doyens of British biochemistry. He was a kindly man with twinkly eyes and more curiosity than most people half his age.

He told me of an ophthalmologist friend who had a severely disabled and mentally retarded young boy as a patient.

Although he was almost blind, he seemed able to read the letters on the optician’s chart very well, but only when his mother was looking at them.

The only explanation appeared to be some form of telepathic communication between the two, and in 1968 Sir Rudolph conducted an experiment in which the boy correctly guessed many of the written numbers or words shown to his mother, even though they were sitting on either side of a screen which prevented him from picking up any visual or auditory cues.

Sir Rudolph concluded that this telepathy had developed to an unusual degree because of the boy’s extreme needs and his mother’s desire to help him.

But, as I discovered, even laboratory experiments involving strangers had produced results which, if less marked, were still compelling.

For example, the years between 1880 and 1939 saw something of a boom in early psychical research, with the publication of more than 186 studies involving trials in which subjects guessed which randomly selected cards a ‘sender’ was looking at.

When the four million individual results were combined in a statistical procedure called meta-analysis, the overall results were hugely significant because they were considerably more accurate than would have been expected from random chance.

Later experiments during the Seventies involved subjects sleeping in a soundproofed laboratory while a ‘sender’ in another room, and in some cases another building, opened a sealed package containing a randomly selected picture and concentrated on it, trying to influence the subject’s dream.

Sometimes the thought transference was very clear: one subject described having dreamed about buying tickets for a prize fight while the sender was looking at a picture of a boxing match.

Occasionally, it was more symbolic, as when the subject dreamed of a dead rat in a cigar box while the sender was looking at a picture of a dead gangster in a coffin. But in 450 such trials the overall results were very significantly above the chance level.

My research has included more than 4,000 cases of psychic phenomena. Many, like Mona Miller’s near-miss in the Blitz, involve mothers.

Hundreds told me that during the months they were breastfeeding, they’d know when their baby needed them, even from miles away, because they began secreting breast milk.

With the help of a midwife, I studied nine nursing mothers in North London during a two-month period, and found that their unexpected ‘let-downs’ of milk when they were separated from their babies very often coincided with their infants experiencing distress.

The odds against this occurring by chance as often as it did were a billion to one, and this telepathic connection makes good evolutionary sense.

Mothers who could tell at a distance when their babies were unhappy would tend to have babies that survived better than those of insensitive mothers.

Such connections often seem to continue even when the children have grown up, with many stories on my database concerning mothers who had an urge to get in touch with their children when they could not have known by any conventional means that they were in trouble.

Many would do so by telephone, the method of communication most commonly mentioned in reports of telepathic experiences in general.

Many people told me they had thought of someone for no apparent reason, and then that person rang in a way that seemed uncanny. Or they knew who was calling when the phone rang, even before they picked up the receiver.

I designed an experiment to test this, a simplified version of which you can try through my website.

This involved asking subjects for the names and phone numbers of four friends or family members before placing them alone in a room with a landline telephone with no caller ID.

I then selected one of the four callers at random and asked them to phone the subject, who had to say who was on the line before answering.

By guessing at random, subjects would have been right about one time in four, or 25 per cent.

In fact, the average hit rate was 45 per cent, very significantly above the level of chance, and these results have been replicated independently at universities in Germany and Holland.

In attempting to explain such phenomena, we need to look far beyond the traditional scientific view that everything is essentially material or physical, including the human mind.

That materialist approach was summed up by Francis Crick, who in 1962 shared a Nobel Prize for the discovery of the structure of DNA.

‘You, your joys and your sorrows, your memories and your ambitions, your sense of personal identity and free will, are in fact no more than the behaviour of a vast assembly of nerve cells and their associated molecules,’ he wrote.

Crick spoke for the scientific mainstream, as did influential neuroscientist Susan Greenfield when she described seeing an exposed brain in an operating theatre.

‘This is all there was to (the patient) Sarah, or indeed to any of us,’ she reflected in a paper published in 2000.

‘We are but sludgy brains and somehow a character and mind are generated in this soupy mess.’

Yet this idea that our minds are fixed physically inside our heads, and that consciousness is nothing but a by-product of the activity of the brain, runs contrary to our everyday experience.

When we look around us, the images of the things we see are outside us, not in our heads. The feelings in my fingers are in my fingers, not in my head.

The human intuitions I have described fit better with the ‘field theory’ of minds.

We are used to the fact that fields exist both within and outside material objects such as magnets and mobile phones, and there is reason to believe that our minds have similar fields which have their roots within our brains, but also extend beyond them.

Extraordinary though this sounds, it’s supported by studies of another remarkable psychic phenomenon — the sense of being stared at.

Most people have felt someone looking at them from behind, turned around and met the person’s eyes.

And most people have experienced the converse: making someone turn around by staring at them.

In extensive surveys in Europe and North America, between 70 and 97 per cent of adults and children reported such experiences.

In a series of interviews with police officers, surveillance personnel and soldiers, I discovered most felt that some people seemed to know they were being observed, even though the watchers were well hidden.

‘A lot of times the crook will just get a feeling that things aren’t right,’ I was told by one narcotics officer.

‘We often have someone look right in our direction even though he can’t see us. A lot of times we’re inside a vehicle.’

Surprisingly, laboratory tests have shown that the sense of being stared at works even when people are looked at on screens, rather than directly.

Our emotional response can be measured by the activity of our sweat glands and this increases in many subjects being watched on CCTV, even though they are unaware of their response.

All this suggests that, whether through direct staring or CCTV, we are capable of ‘touching’ each other with our sight — further evidence that our minds are not confined to the inside of our brains.

With telepathic communication, it seems that these fields somehow interact at a distance, picking up feelings, needs or thoughts across space.

As for presentiments and premonitions, these imply links across time, as we tune into our future mental states.

That such links are real was suggested by a series of experiments in the U.S. and Holland over the past 20 years.

These measured responses to a series of noxious smells, mild electric shocks, emotive words and provocative photographs, interspersed with calming stimuli which had no physiological effect on subjects at all.

No one, not even the experimenters, knew what kind of stimuli the computer involved would produce next, but in a significant number of cases the subjects reacted to the unpleasant stimuli some three or four seconds in advance, somehow connecting with their future selves who would be experiencing the stimuli for real.

These findings are fascinating in themselves but, as I will explain in Monday’s Mail, psychic phenomena are not restricted to human beings.

There are amazing stories of telepathy and premonitions of disaster in many other species, including pet dogs.

As for exactly how such phenomena operate, it may be years before we understand them, but an important first step is for scientists to acknowledge that they exist, and that the minds of both animals and humans interact in as yet unexplained ways.

According to Kurzweil [yes, the same guy who builds synths], his logarithmic graph of 15 lists of paradigm shifts for key historic events shows an exponential trend. he lists' compilers include Carl Sagan, Paul D. Boyer, Encyclopædia Britannica, American Museum of Natural History, and University of Arizona.

Infinity

Infinity (symbol: ∞) refers to something without any limit, and is a concept relevant in a number of fields, predominantly mathematics and physics. Having a recognizable history in these disciplines reaching back into the time of ancient Greek civilization, the term in the English language derives from Latin infinitas, which is translated as "unboundedness".

In mathematics, "infinity" is often treated as if it were a number (i.e., it counts or measures things: "an infinite number of terms") but it is not the same sort of number as the real numbers. In number systems incorporating infinitesimals, the reciprocal of an infinitesimal is an infinite number, i.e. a number greater than any real number. Georg Cantor formalized many ideas related to infinity and infinite sets during the late 19th and early 20th centuries. In the theory he developed, there are infinite sets of different sizes (called cardinalities). For example, the set of integers is countably infinite, while the set of real numbers is uncountably infinite.

Bioluminescence

Bioluminescence is the production and emission of light by a living organism. Its name is a hybrid word, originating from the Greek bios for "living" and the Latin lumen "light". Bioluminescence is a naturally occurring form of chemiluminescence where energy is released by a chemical reaction in the form of light emission. Fireflies, anglerfish, and other creatures produce the chemicals luciferin (a pigment) and luciferase (an enzyme). The luciferin reacts with oxygen to create light. The luciferase acts as a catalyst to speed up the reaction, which is sometimes mediated by cofactors such as calcium ions or ATP. The chemical reaction can occur either inside or outside the cell. In bacteria, the expression of genes related to bioluminescence is controlled by an operon called the Lux operon.

Bioluminescence occurs in marine vertebrates and invertebrates, as well as microorganisms and terrestrial animals. Symbiotic organisms carried within larger organisms are also known to bioluminesce.

Alan Turing: Separating the man and the myth

Image

Acclaimed code-breaker Alan Turing was undoubtedly one of the greatest minds of the last century but we should always remember his achievements were not a one man show, says Quentin Cooper.

It’s exactly 100 years since the birth of Alan Turing. And just over 58 years since his death. An event which left scarcely a ripple in the media of the time, and which might have left none at all had it not been for the manner in which it happened.

Under the headline “Death Apple By His Bed”, the Daily Mail of 11 June 1954 covered the coroner’s findings that this “bachelor” who “lived alone” committed suicide by means of a cyanide soaked apple while the balance of his mind was disturbed. Although he is described as “one of Britain’s most brilliant mathematicians”, Turing’s name was not remotely well enough known to make it into the headline, and the piece takes up barely a couple of column inches, one of dozens of stories on that page alone. Brief as the Mail’s account was, they did more than most other national papers in at least reporting that Turing had died.

Fast forward to now, and Turing has gone from being a man whose life was seen as less interesting than his death, to one requiring 12 months to celebrate his achievements and influence. 2012 has been declared “Alan Turing Year” with an official organising committee and events across some 50 countries and organisations. There are exhibitions, conferences, TV and radio programmes, even a special UK postage stamp. That apple by his deathbed has become the most famous in science since Isaac Newton’s windfall, with claims that Turing poisoned it so he could mimic the one in his favourite fairy-tale, Disney’s Snow White, and – repeatedly – that it inspired Apple’s famous once-bitten logo. Although writer/actor/presenter/technophile Stephen Fry says that when he asked Apple founder Steve Jobs if the story is true, Jobs replied “It isn’t true but God, we wish it were”.

‘Modern hero’

There are many reasonable reasons why Turing is now so highly regarded. It helps he was a leading figure in the World War II code-breaking work at Bletchley Park: he developed the electromechanical “Bombe” which deciphered messages sent using the fiendishly complex German Enigma machines, work which ultimately led to the first computers. It also helps that over the years the layers of secrecy which surrounded much of what he did have steadily been stripped away, only belatedly allowing the full magnitude of his accomplishments to be appreciated. And it perhaps helps, although it certainly did not during his lifetime, that after the war this “bachelor” who “lived alone” – which many Daily Mail readers of the time would have correctly taken to imply he was homosexual – was subjected to persecution, prosecution and ultimately chemical castration, which may have led him to take his own life while still only 41. Such was the widespread anger at this injustice that 30,000 people signed a petition calling for a government apology, and in 2009 then Prime Minister Gordon Brown issued an unequivocal one, saying that it was horrifying Turing had been treated “so inhumanely”.

All of this goes a long way to explaining why we find ourselves in the middle of Alan Turing Year. But not quite all the way. Having been propelled from unfair obscurity to unlimited acclaim, Turing has now reached that most attractive and semi-mythic status of a modern science hero. Attractive as in desirable, but also attractive as in things keep being drawn towards him.

Besides various plays and TV dramas based on his life, a fictionalised version of Turing turns up as a character in Neal Stephenson’s classic geek novel Cryptonomicon; he’s clearly a major inspiration for the character of the - resolutely heterosexual - cryptographer Tom Jericho in the film of Robert Harris’ Enigma (the two are more distinct in the book), and he even managed a cameo cartoon strip appearance in inventively sweary British adult comic, Viz.

Which would all be fine and even largely good in terms of depicting scientists positively, if it weren’t that this is a two-way process and we’ve begun to accept fantasy elements as being facts about Turing’s life.

Turing is now regularly described as being the “father” of computing. Or of computing science. Or artificial intelligence. Sometimes all three. As the only name most of us are familiar with among the code-breakers at Bletchley Park, he is often depicted as if he unraveled the secrets of the Enigma machine entirely unaided. And it’s often said that without him, what I’m writing this on (and in all likelihood you’re reading it on) would not exist.

None of that is entirely a lie. None of it is really true . Which may sound like an attempt at an enigma, but it’s not. As I have written before, we are fond of the myth of the lone genius. Turing may have “lived alone” but he didn’t work alone. His famous code-breaking Bombe, for instance, benefitted from tweaking by mathematician Gordon Welchman and engineer Harold Keen. And it got its name because it was itself based on an earlier device to crack the Enigma ciphers called the Bomba developed by Polish cryptologists.

Unquestionably he played the leading role – but it was not a one man show. And the claims about Turing being the big daddy of computing and artificial intelligence are even more questionable: both have many fathers (and a few mothers) and even without his considerable input does anyone really think we would not have computers very similar to the ones we now use?

So perhaps we need a different kind of Turing test – not one that can aid us in telling machine from human, but one which enable us to discriminate between the facts and fictions as our desire to have science heroes risks us forgetting the collective, collaborative nature of most scientific advances. Turing was undoubtedly one of the greatest minds of the last century, but shedding light on his achievements shouldn’t involve plunging all those he worked with into the shadows.

Acclaimed code-breaker Alan Turing was undoubtedly one of the greatest minds of the last century but we should always remember his achievements were not a one man show, says Quentin Cooper.

A little known fact: lan Turing was also a Kazoo virtuoso

Wait a minute, he didn't live long enough to use Kazaa.

Oh..... Never mind.
