Melvyn Bragg and guests discuss the origin of the concept and historical role of the scientist. The word "science" first appeared in the English language in 1340 and ever since its meaning has been in a state of flux. The notion of "the scientist" has had a similarly evolving history. For some, "the scientist" does not truly appear until after the Renaissance, others put its emergence much later than that. When did the words and concepts we recognise today take on their contemporary meaning? How...
Oct 24, 2002•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss the impact of politics on psychoanalysis. The 20th century saw the birth and rise of psychoanalysis. Sigmund Freud led people to think about how the mind functioned and how our behaviour might be understood through the process of working with a psychoanalyst, either one-to-one or in a group. Freud thought a lot about this process and in 1922 he published Group Psychology and the Analysis of the Ego, in which he pronounced that the group "wants to be ruled and oppr...
Jul 11, 2002•29 min•Transcript available on Metacast Melvyn Bragg and guests discuss the history of drugs. Throughout history people have taken them to alter their perceptions and change their moods. The attractions lie in the promise of instant pleasure and the possibility of heightened perceptions. Nietzsche said that no art could exist without intoxication and believed that a dream-like state was an essential precondition to superior vision and understanding. But artists and writers from De Quincey to Coleridge to Huxley have found drugs to be ...
May 23, 2002•28 min•Transcript available on Metacast Melvyn Bragg examines whether world is a fundamentally chaotic or orderly place. When Newton published his Principia Mathematica in 1687 his work was founded on one simple message: Nature has laws and we can find them. His explanation of the movements of the planets, and of gravity, was rooted in the principle that the universe functions like a machine and its patterns are predictable. Newton’s equations not only explained why night follows day but, importantly, predicted that night would contin...
May 16, 2002•42 min•Transcript available on Metacast Melvyn Bragg examines the physics of reality. When Quantum Mechanics was developed in the early 20th century reality changed forever. In the quantum world particles could be in two places at once, they disappeared for no reason and reappeared in unpredictable locations, they even acted differently according to whether we were watching them. It was so shocking that Erwin Schrodinger, one of the founders of Quantum Theory, said "I don’t like it and I'm sorry I ever had anything to do with it." He ...
May 02, 2002•28 min•Transcript available on Metacast Melvyn Bragg examines Extra Terrestrials. New planets have been observed far beyond our solar system and telescopes are being built that will enable us to look for water and oxygen on these distant planets. If water and oxygen are present, there is every reason to suppose that some form of life might also exist there. It has even been suggested that we might find life within our own solar system. One of Jupiter’s moons, Europa, appears to be covered in an ice-crusted ocean and there is evidence ...
Apr 04, 2002•28 min•Transcript available on Metacast Melvyn Bragg examines the history of mankind's quest to understand the human body. The Greeks thought we were built like pigs, and when Renaissance man first cut his sacred flesh it was an act of heresey. We trace the noble ambitions of medical science to the murky underworld of Victorian grave robbing, we trace 2000 years of anatomical study. From the great showman Vesalius, enthralling the Renaissance Artists in the operating theatres of Italy to the sad and gruesome pursuits of Burke and Hare...
Feb 14, 2002•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss the shape of the universe. In the Beginning, runs one account, was the Big Bang. All matter in existence today originated around 13 billion years ago in a phenomenally hot, extraordinarily condensed primordial atom that exploded with incredible force. Hydrogen and helium were shot across the firmament, gravity caused the gases to condense into clouds and in these clouds the first stars were formed, then galaxies came and more galaxies in clusters, onwards and outw...
Feb 07, 2002•28 min•Transcript available on Metacast Melvyn Bragg examines one of the greatest scientific breakthroughs of the 20th century, and certainly the most controversial; the development of nuclear physics. Harnessing the enigmatic qualities of the atom’s tiny core brought us nuclear power and gave us The Bomb, a breakthrough with such far-reaching consequences that it moved the physicist Albert Einstein to say, “Had I known, I should have become a watch maker”.How can such outlandish power be released from such infinitesimal amounts of ma...
Jan 10, 2002•28 min•Transcript available on Metacast Melvyn Bragg looks at the development of the science of genetics. In the 1850s and 60s, in a monastery garden in Burno in Moravia, a Franciscan monk was cultivating peas. He began separating the wrinkly peas from the shiny peas and studying which characteristics were passed on when the next crop of peas were grown. In this slow and systematic way Gregor Mendel worked out the basic law of heredity and stumbled upon what was later to be described as the fundamental unit of life itself…the gene.But...
Dec 13, 2001•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss the science of Oceanography. In 1870 Jules Verne described the deep ocean in 2,000 Leagues Under the Sea. He wrote: “The sea is an immense desert where man is never alone for he feels life, quivering around him on every side.” This was actually closer to the truth than the science of the time, when ‘Azoic Theory’ held sway and it was believed that nothing could exist below 600 metres. Now we estimate that there are more species in the deep ocean than in the rest o...
Nov 22, 2001•28 min•Transcript available on Metacast Melvyn Bragg discusses the origin of the Earth. Ideas used to be very clear about its origins. Bishop Ussher, in 1654 arrived at an exact figure and specified it in his work Annalis Veteris et Novi Testamenti: He deduced that work on Planet Earth began at exactly 9am, on Monday 23rd October 4004 BC. The date was then printed in the margin of The Bible and preached from the pulpit, and right up to the nineteenth century to the left of ‘In The Beginning…’ was specified ‘Before Christ 4004’.Christi...
Jul 05, 2001•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss Black Holes. They are the dead collapsed ghosts of massive stars and they have an irresistible pull: their dark swirling, whirling, ever-hungry mass has fascinated thinkers as diverse as Edgar Allen Poe, Stephen Hawking and countless science fiction writers. When their ominous existence was first predicted by the Reverend John Mitchell in a paper to the Royal Society in 1783, nobody really knew what to make of the idea - they couldn’t be seen by any telescope. Alt...
Apr 12, 2001•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss the significance of fossils. In the middle of the nineteenth century the discoveries of the fossil hunters used to worry poor Ruskin to death, he wrote in a letter in 1851, “my faith, which was never strong, is being beaten to gold leaf…If only those Geologists would let me alone I could do very well, but those dreadful Hammers! I hear the clink of them at the end of every cadence of the Bible verses.”The testimony of fossils over the ages has been remarkably eloq...
Mar 22, 2001•42 min•Transcript available on Metacast Melvyn Bragg examines Quantum Gravity. Early in the 20th century physicists were startled by the realisation that the smallest things in the universe do not obey Newton’s laws of gravity. Ripe apples fall from trees, billiard balls roll mostly on the table and the moon orbits the Earth in thrall to its gravitational pull, but there is no such force of gravity at work in the world of very small things. It seems there is one set of rules for the realm of every day objects, and a very different set...
Feb 22, 2001•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss what drove the British Empire, especially in Victoria’s century. Was it science, more specifically, the science of plants, of agriculture, a scientific notion of nature and the improvement of nature? Was this seemingly rather adjacent notion - that the source of Empire can be found in Kew Gardens, Royal, Botanical, rather than in the muzzle of a gun or in the purse of a plunderer or in the consciousness of a conqueror - was science “the force that was with us?” Fr...
Feb 01, 2001•28 min•Transcript available on Metacast Melvyn Bragg looks at the deep claims made for mathematics, the discipline some believe to be the soul and true key to the understanding of all life, from the petals on the sunflower to the pulse in our wrists. The notion that mathematics is akin to theology might take some taking in at first. But from the first, in the West, they were. To Pythagoras, numbers were mystical and “prove” God. To Plato, who, it is claimed, has driven mathematics for over two thousand years, the ideals beyond the rea...
Jan 11, 2001•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss role of Freudian analysis in understanding the great works of literature. Freud said, “The poets and philosophers before me discovered the unconscious. What I discovered was the scientific method by which the unconscious can be studied”. Psychoanalysis has always been more than a ‘talking cure’ and it has strong ties to literature, but one hundred years after the publication of the first great work of psychoanalysis, The Interpretation of Dreams, critics are putti...
Nov 09, 2000•42 min•Transcript available on Metacast Melvyn Bragg and guests discuss Evolutionary Psychology. Richard Dawkins redefined human nature in 1976, when he wrote in The Selfish Gene: “They swarm in huge colonies, safe inside giant lumbering robots, sealed off from the outside world, communicating with it by tortuous indirect routes, manipulating it by remote control. They are in you and me; they created us body and mind; and their preservation is the ultimate rational of our existence…they go by the name of genes and we are their surviva...
Nov 02, 2000•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss the Laws of Nature. Since ancient times philosophers and physicists have tried to discover simple underlying principles that control the Universe: In the 6th Century BC Thales declared “Everything is water”, centuries later Aristotle claimed that all of creation was forged from four elements, Newton more successfully laid down the Law of Universal Gravitation and as we speak, contemporary scientists are struggling to complete the task of ‘String Theory’ - the ques...
Oct 19, 2000•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss the question of consciousness, our sense of self, and how we are able to imagine things when they are not there, which are problems that have troubled the great minds of philosophy for thousands of years. Consciousness has been linked to language, has been married to the mind and divorced from the body; it has been denied to animals, opposed to the subconscious and declared irreducible, but still it defies definition, and the debate rages on as to why we evolved i...
Jun 29, 2000•43 min•Transcript available on Metacast Melvyn Bragg and guests discuss the chemical elements. The aim and challenge in chemistry, according to the Encyclopaedia Britannica, is the understanding of the complex materials which constitute everything in existence since the Big Bang, when the whole universe emerged out of the two elements of hydrogen and helium. For Aristotle there were four elements: Earth, Air, Fire and Water. Now there are one hundred and eight, sixteen of which are produced artificially, and none of which figure in Ar...
May 25, 2000•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss the evolution of the human species. Where did we come from - we being Homo Sapiens? Let’s not go back to the Big Bang or in search of Genesis, but sift through the evidence from biology, palaeontology, climatology and anthropology.The story of human evolution is one that stretches back over five million years, and during that time there are reckoned to have been between fifteen and twenty species of hominid to have walked this planet. From the earliest (Genus) Aus...
Apr 27, 2000•28 min•Transcript available on Metacast Melvyn Bragg examines the science of taxonomy. The Argentinean author Jose Luis Borges illustrated the problematic nature of scientific classification when he quoted from an ancient Chinese Encyclopaedia, the Celestial Emporium of Benevolent Knowledge. On these remote pages, in a complete absence of Phylum, Genus and Species, animals are divided into: (a) those that belong to the Emperor, (b) embalmed ones, (c) those that are trained, (d) suckling pigs and those that tremble as if they were m...
Apr 06, 2000•28 min•Transcript available on Metacast Melvyn Bragg examines 20th century physics’ quest for the ultimate theory of everything. Einstein left us with his theory of General Relativity, which explained how gravity works on the scale of stars, galaxies, and the universe itself and Schroedinger left us with the equation that explained the mechanics of the tiny quantum realm. Both theories work to wonderful effect in their own worlds, but (and this is the sticking point) gravity is strangely absent from the quantum realm and planets behav...
Feb 24, 2000•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss Johann Wolfgang von Goethe, the great poet and dramatist, famous for Faust, for The Sorrows of Young Werther, for Storm und Drang and for being a colossus in German literature. Born in the middle of the eighteenth century he lived through the first third of the nineteenth. He wrote lyric and epic verse, literary criticism, prose fiction, translations from 28 languages, he was a politician as well and was hailed by Napoleon as the boundless measure of man; but for ...
Feb 10, 2000•28 min•Transcript available on Metacast Melvyn Bragg discusses the social and economic consequences of the information revolution. There are now more than 200 million people connected to the internet world-wide. The world’s biggest ever merger has just seen Time Warner united with the internet service provider America Online, and in the United States alone it is predicted that transactions conducted in cyberspace will account for 327 billion dollars worth of business by 2002. Should we be pleased? Is it the ‘third wave’ as Dr Toffler ...
Jan 13, 2000•28 min•Transcript available on Metacast Melvyn Bragg discusses climate change. In 1999 the weather gave the planets occupants a terrible beating: 16,000 people lost their lives as a result of storms. Some 15 million people were left homeless and 10,000 died when the worlds worst cyclone swept across eastern India. Hurricane Floyd wreaked 4.3 billion pounds worth of damage in the United States, Typhoon Bart hit Japan and Typhoon York hit Hong Kong and Macau. Western Europe is unused to hurricane force winds, but since Christmas 80 pe...
Jan 06, 2000•28 min•Transcript available on Metacast Melvyn Bragg and guests discuss the history of mankind’s attempt to understand the nature of time. At the end of the 19th century, H.G.Wells imagined travelling through time in The Time Machine; “The palpitation of night and day merged into one continuous greyness; the sky took on a wonderful deepness of blue, a splendid luminous colour like that of early twilight; the jerking sun became a streak of fire, a brilliant arch in space”. When he was writing we thought time was unbending and universal...
Dec 30, 1999•28 min•Transcript available on Metacast Melvyn Bragg examines the technological advances and ethics of modern medicine. On an average working day about three quarters of a million of us go to the doctors. About a hundred thousand are visited by nurses and other health professionals. Then there are the three hundred thousand that go to the dentist. Health is a central preoccupation. It is also big business, saving life, lengthening life and even promising a stab at eternal life. Yet while some technology is Space Age, the morality is ...
