"100 years ago, a deceptively simple formula was written." "It held the key to how our world began and why it works as it does." "It led to the creation of the atom bomb and it uncovered the darkest secrets of the universe." "Its author was a youthful Albert Einstein." "It's one of the most important and certainly the most famous equation in the world." "E equals mc squared." "All aboard." "When we think of E = mc2 we have this vision of Einstein as an old wrinkly man with white hair." "E = mc2 is not about an old Einstein." "It's actually about a young, energetic, dynamic, even a sexy Einstein." "But while we've all heard of young Einstein's equation very few of us know what it means." "In fact, E=mc2 is so remarkable that even Einstein wasn't sure if it was really true." "Albert, darling, you're later then I expected tonight." "We've only got sausage and cheese tonight." "Which is it?" "We need to talk!" "Has something happened?" "Oh, no, nothing, sorry." "No." "I spend most of the day staring at the window at work looking at trains." "And I started to think about an object and how much energy it had." " Can I explain it to you?" " Of course you can." "But first, dinner!" "Food, then talk." "I think the gods are laughing at me." "But the gods were not laughing at Einstein." "What he'd done has combined in one stunning insight, the work of many great visionaries." "This is the story of Einstein and all the scientists who went before." "Who'd fought and even died to create each part of the equation." "It's a tale of ambition, betrayal, heartache and deceit." "And the story of E=mc2 starts long before the birth of its creator, Einstein, with the discovery of E, for energy." "In the early 19th century, scientists didn't think in terms of energy." "They thought in terms of individual powers or forces." "These were all disconnected, unrelated things:" "the power of the wind, the force of a door closing, the crack of lightning." "The idea that there might be some sort of overarching, unifying energy which lay behind all these forces had yet to be revealed." "One poor, hungry man's drive to understand the hidden mysteries of nature would begin to change all that." "Young Michael Faraday hated his job." "He was uneducated;" "the son of a blacksmith, he'd been lucky to become a bookbinder's apprentice." "But Faraday craved one thing, he craved knowledge." "He read every book that passed through his hands." "He developed a passion for science." "All of his free time and his meager wages were poured into his self-education." "He was on the threshold of an incredible journey into the invisible world of energy." "Faraday had impressed one of his master's customers and was rewarded with a ticket that would change his life." "Can I pass, please?" "Can I pass?" "Some of us are trying to improve ourselves, if people will let us." "Of course, of course." "Pass, pass." "This way to a better life." "In the early 1800s, science was the pursuit of gentlemen something Faraday was clearly not." "He had a rudimentary education, he'd read widely he'd gone to public lectures, but in 1812, he was given tickets to hear Sir Humphry Davy, the most prominent chemist of the age." "Nineteenth century scientists were the pop stars of their day." "Their lectures were hugely popular, tickets were hard to come by, and Davy reveled in his status." " They're waiting." " I know." "He was also a keen follower of the latest fashion:" "nitrous oxide, or "laughing gas"." "He said it had all the benefits of alcohol without the hangover." "Electricity, ladies and gentlemen, a mysterious force that can unravel the confusing mixture of intermingled substances that surround us and produce pure, pure elements." "How do we do this?" "Davy was an absolutely first-rate scientist however, many will come to say that his greatest discovery is Michael Faraday." "...unknown metals." "Unknown that is until I," "I isolated potassium from molten potash and sodium, as I showed you last time, from common salt." "That same metal..." "Faraday may not have been born a gentleman, but he wasn't going to let class barriers stop him from pursuing a career in science." "He worked for nights on end to bind his lecture notes into a book for his new hero." "Lord, help me to think only of others, to be of use to mankind." "Help me be part of the Great Circle that is your work and love." "Lord, I am your servant." "This is excellent work, Faraday." "So, what is it you aim to do with your life?" "My desire, sir, is to escape from trade which I find vicious and selfish and to become a servant of science, which I imagine makes its pursuers amiable and liberal." "Really?" "Well, I shall leave it to the experience of a few years to set you right on that score." "Look, I haven't anything at the moment." "I'll send a note if anything comes up." "Despite this humiliating setback," "Faraday was determined to break free from his daily toil." "His patience was rewarded." "Newman, meet Mr. Michael Faraday, he's going to be my helper while I recover." "He assures me he is a Christian fellow." "Perhaps with God and Faraday in charge of the chemicals you and I will be safe in our place of work." "Thank you, Professor Davy." "Welcome Faraday." "Oh, no, thank you." "And thank you, Sir Humphry." "Just stick to your job and do as you're told, and you'll be fine, Faraday." "Faraday became the laboratory assistant, eagerly absorbing every scrap of knowledge that Davy deigned to impart." "But in time the pupil would surpass the master." "The big excitement of the day was electricity." "Another charge, Newman." "The battery had just been invented and all manner of experiments were being performed." "But no one really understood what this strange force of electricity was." "The academic establishment, at the time, thought that electricity was you know, like a fluid flowing through a pipe, pushing its way along." "But, in 1821, a Danish researcher showed that when you pass an electric current through a wire and place a compass near it, it deflected the needle at right angles." "This was the first time researchers had seen electricity affect a magnet:" "the first glimpse of two forces, which had previously been seen as entirely separate, now unified in some inexplicable way." "Faraday, come look at this." "You're the bright spark around here, perhaps you can work it out." "Oersted's reported an amazing finding." "We're just replicating it here." "Let's try the compass on the other side." "Now, that is remarkable." "But if the electrical force is flowing through the wire, why does the needle not move in the same direction, parallel to the wire?" "Quite." "Let's try turning the whole apparatus round." "Again, Newman." "So, the electrical force goes this way, the compass points that way." "How can one affect the other?" "Perhaps the electricity is throwing out some invisible force as it moves along?" "What?" "Perhaps some sort of electrical force is emanating outwards from the wire." "Oh, my dear boy, let me tell you that at the University of Cambridge, electricity flows through a wire, not sideways to it." "Well, that may be what they teach at Cambridge, but it doesn't explain what's happening before our eyes." "Now, now." "Let's just get on." "Let's swap the compass to below the wire." "Why the compass was deflected at right angles, why the electricity was affecting the compass at all, dumbfounded Davy and many others." "As we celebrate the marriage of Michael and Sarah..." "For Faraday, however, the problem became an obsession." "It was a fascination inspired by his religion." "For him this was a way to understand God's hidden mysteries." "There is a small, almost persecuted group in London called the Sandemanians." "They were religious..." "not really a sect, they were just a small sub-sect, sort of like Quakers." "Faraday was a member of that group." "It was a very gentle, decent group." "They believed that underneath the whole surface of reality, everything was created by God in a unified way that if you opened up one little part of it you could see how everything was connected." "Michael Faraday was someone who, like Einstein, thought in terms of pictures." "Faraday was different from anybody else." "He had a flair for understanding his experiments, for understanding what was really going on inside them." "By methodically placing a compass all around an electrified wire," "Faraday started to notice a pattern." "What everyone else at the time had been taught was that forces travel in straight lines." "Faraday was different." "Faraday imagined that invisible lines of force flowed around an electric wire." "And then he imagined that a magnet had similar lines emerging from it and that those lines would get caught up in this flow." "It was a bit like a flag in a wind." "But Faraday's great leap of the imagination was to turn this experiment on its head." "Instead of an electrified wire moving a compass, he wondered if he could get a static magnet to move a dangling wire." "I've never seen you like this, Faraday." "You look like a happy child." "I'm shaking, Newman." "Underneath I'm shaking." "You see, John, you see?" "Yes." "This is the experiment of the century." "It's the invention of the electric motor." "Scale up the magnets and the wires;" "make them really big." "Attach heavy weights to them and they'll be dragged along." "But almost more importantly, he's inventing a new kind of physics here." "Although he didn't realize it at the time," "Faraday had also just demonstrated the overarching principle of energy." "The chemicals in the battery had been transformed into electricity in the wire, which had combined with the magnet to produce motion" "Behind all these various forces there was a common energy." "A couple of months earlier," "Davy had been elected President of the Royal Society, which was the elite body of English science." "But then he saw this great discovery published in the Quarterly Journal of Science." "I don't know if he was envious, but he certainly saw that this young man who had been his assistant, this mere blacksmith's son, had come up with one of the greatest discoveries of the Victorian era." "Davy accuses Faraday of plagiarizing similar work from another eminent British scientist, William Wollaston." "So Faraday, what does Wollaston make of all this?" "He's written to me and assures me that he's taken no offense, and he acknowledges that what I published was entirely my own work." "Quite, quite." "Davy is just being an ass." "But will Davy now retract his allegation?" "Sadly, no." "In fact, he is still vehemently opposed to you being elected a member of the Society." "Really?" "And what do you think?" " Faraday, my dear boy, you have my vote." " And mine." " And I believe you even have Wollaston's." " Oh, what a mess." "Well, no matter, no matter." "It's the science that counts." "So, tell me, how does this wire of yours spin round its magnet?" "What mysterious forces are at play?" "There seems to be an electro-magnetic interaction." "In my mind, I see a swirling array of lines of force spinning out of the electrified wire, like a spiraling web." "But invisible lines of force?" "It's all a bit vague, isn't it?" "Faraday, might I have a word in private?" "Certainly." "Listen, Faraday, let's stop this nonsense." "I want you to take down your ballot paper from the notice board." "Sir Humphry, I see no reason to take it down." "My friends have proposed me." "It is they who put the paper up." "I will not take it down." "Good day." "Faraday was elected to the Royal Society." "Davy died five years later, a victim of his puncheon for laughing gas." "In time, Faraday's world of invisible forces would lead to a whole new understanding of energy." "He'd started what Einstein would like to call "The Great Revolution"." "Albert Einstein grew up in an industrial society obsessed with energy." "All the forces of nature had been unified and man taught he was the master of this new power." "Young Einstein was going to pull this cosy world view apart." "My father and uncle wanted to make their fortune by bringing electric light to the streets of Germany." "From an early age I loved to look at machines, understand how things work." "He's going to kill himself." "Albert, stay there." "I experienced a miracle when my father showed me a compass." "I trembled and grew cold." "There had to be something behind objects that lay deeply hidden." "At high school, they had their ideas about what I should learn," "I had my own." "I was merely interested in physics, maths, philosophy and playing the violin." "Everything else was a bore." "Einstein, on your feet." "As you obviously know everything about geology, tell me how do the rock strata run here?" "It's pretty much the same to me whichever way they run, Herr Professor." "Einstein's teachers tried to drum into him, as Faraday had shown, that energy could be converted from one form into another." "They also believed that all forms of energy had already been discovered." "Einstein was going to prove them wrong." "He would discover a new, vast reservoir of energy, hidden where no other scientist had ever thought of looking, deep in the heart of matter." "A hundred years before Einstein's birth," "King Louis the XV was on the throne of France, but the ancient, absolute power of the monarchy over the people was starting to be challenged." "Jacques, leave the windows, forget the rain, we need air." "The French Revolution was just around the corner." "This was the era of the Enlightenment, when intellectuals believed very firmly that the way forward lay in science." "And they felt that one of the first tasks that lay ahead of them was to rationalize and to classify every single kind of matter so they could see how it all interacted together." "Antoine Lavoisier, a wealthy, aristocratic young man decided to take up this task to see if there was some basic connection between all the stuff of everyday life, all the different substances in the world." "But what worked for Lavoisier as a scientist,his meticulous, even obsessive attention to detail, was also to be his downfall." "Monsieur Lavoisier, you are, if my eyes do not deceive me, consuming only milk this evening." "First you had a glass of milk, now you are "eating" a bowl of milk." "Will you move on to a plate of milk?" "Your precise observations commend you as a lady of scientific curiosity," "Mademoiselle, most unusual." "As you seek knowledge, so I shall dispense it." "For the last five weeks I have taken nothing but milk." "Good god, man, I would rather die than fast on milk for five weeks." "Are you in the grip of some horrendous ailment?" "On the contrary." "I am investigating the effects of diet on health." "Monsieur, with the greatest of respect to a member of the Royal Academy of Sciences, your gut must think your throat has been slit." "Whereas your gut, Count, is, no doubt, petitioning the Academy for a widening of your throat." "Marie Anne, how dare you insult the Count?" "Don't forget what the Count offers." "Not just marriage, but think of how you will be introduced to all the Salons." "You will be the toast of Paris." "Would it not be a shame, Madame, to burden you with the duties of matrimony before you have had a chance to experience your curiosity for nature?" "Shall we all go through?" "It's getting rather hot in here." "Do you really plan to marry de Amerval?" " There is a plan, but it is not mine." " Then I must contrive to save you." "Lavoisier wasn't a scientist by profession." "He was the head of tax enforcement in Paris." "His great idea was to build a huge wall around the city and to tax everything that came and went." "But his taxes on the simple things in life-bread, wine and cheese did not endear him to the average Parisian." "However, this scrupulous, fastidious young man did still allow himself the occasional act of passion." "In 1771, Lavoisier married Marie Anne Paulze, the daughter of his colleague in the tax office." "Thus he saved her, as he had promised, from an arranged marriage to a count 40 years her elder." "Allow me to show you something." "Lavoisier, I think, found his job as a tax collector really rather tedious, and the times he looked forward to were the evenings and the weekends when he could indulge his passion for chemical experimentation." "And he called those times his "jours de bonheur", his "days of happiness"." "Madame." "What will happen if I take a bar of copper or iron and leave it outside in the rain for months on end," "Madame Lavoisier?" "Mmmm, Monsieur Lavoisier?" "The metals what will become of them?" "Is this a verbal examination prior to an examination proper, sir?" "I merely seek the truth." "Then you toy with me, Monsieur, for you know the truth." "The copper will become covered in a green verdigris and the iron will rust." "I believe the term is "calcined"." "Most impressive, my charming wife." "But let me press you further." "Mmmm." "When the metal rusts, does it get heavier or lighter?" "Why, sir, I think you mean to trap me." "Ooooohhh..." "Then perhaps this little butterfly should land and allow me take a closer look." "Every last citizen in France of sensible age knows that when a metal rusts it wastes away, it gets lighter and eventually disappears." " Ah, but..." " Huh?" "Stop." "I have not finished." "Contain yourself, sir." "There is more." "In a recently published pamphlet by a brilliant young chemist," "Antoine Lavoisier demonstrates that the iron combines with the air." "It, in fact, becomes heavier." "Most impressive." "I intend..." "Now whatever you intend, Monsieur, I intend to be by your side." "I will learn all I can about your science and become your worthy colleague." "Then let me show you how the iron combines with the air to form such a delicate union." "Tomorrow, Monsieur, tomorrow." "Marie Anne learned chemistry at her husband's side, but soon sought other ways to contribute to his work." "She learned English so that she could translate contemporary scientific works." "She took drawing lessons so that she could record in forensic detail the minutiae of their work together." "She ran their laboratory and was the public face of "Lavoisier Enterprise"." "She was central to the whole research effort." "Monsieur, that is a terrible thing to say." "You are a cheeky man." "This way please, gentlemen." "Messieurs, it is my great ambition to demonstrate that nature is a closed system, that in any transformation, no amount of matter, no mass, is ever lost, and none is gained." "Over here, please." "This precise amount of water is heated to steam." "This steam is brought into contact with a red hot iron barrel embedded in the coals." "From this end, we cool the steam, but, interestingly, we collect less water than we started with." "So clearly we lose a certain amount of water." "However, we also collect a gas, and the weight of the iron barrel increases." "Now, when we combine these two increases, the new weight of the iron barrel and the gas we have collected, they are exactly equal to the weight of the lost water." "Aha!" "But is it atmospheric air, Monsieur Lavoisier?" "No, no because I am measuring it, to the very last grain," "I can see that it is lighter than the air around us, and moreover, it is flammable." "Voila." "Water is made out of hydrogen and oxygen." "So what he had done is get the oxygen to stick to the inside of a red hot iron rifle barrel." "He was basically just making rust, which is oxygen iron, but he was making the rust really quickly." "Now that left the hydrogen-what he called combustible "air"" "and that was just floating around as a gas." "No mass had been lost, it had merely been transformed, and now he wanted to transform it all back into water." "This is only the beginning." "In the next few months, I hope to demonstrate that I can recombine this combustible air with vital air and transform them both back into water." "I will recreate exactly the same amount of water that was lost here in this process." "It is my hope to complete the cycle, water into gas into water," "and not a drop lost." "For a long time, Lavoisier had suspected that the exact amount of matter, the mass, involved in any transformation was always conserved." "But to prove this he had to perform thousands of experiments, and he had to do the measurements with incredible accuracy." "That's where his great wealth from being a tax collector came in." "He could afford to commission the most sensitive instruments ever built." "He became obsessed with accuracy." "But Lavoisier's exacting methods were also starting to anger the growing mob of hungry, disenchanted Parisians." "Antoine, Antoine." "Oh, wake up, Antoine." "I'm sorry." "What time is it?" "It is almost time to receive Monsieur Marat." "The Academy asked you to assess his designs." "He claims to have made a great discovery." "Oh Antoine, have you forgotten?" "My god, another charletan with an idea to peddle!" "God give me patience." "Well, Monsieur Marat." "Monsieur, I have invented a device which projects an image of the substance of fire onto a screen." "You see, when a lantern is shone through a flame we see a shimmering pattern above the flame." "My device renders the substance of fire visible." "Have you collected it, this substance of fire?" "Have you trapped it and measured it?" "Well, no, but, but one can see it." "I'm sorry, in the absence of exact measurements, of precise observations, without rigorous reasoning, one can only be engaging in conjecture." "So this is not science." "I am not given to conjecture, Monsieur." "No." "If you will you excuse me, I am extremely busy today" "Thank you." "Thank you." "So that is all?" "Then, good day, Monsieur." "Let me guess, Marat." "The King's scientific despot has decreed that your invention does not conform to the version of the truth as laid down by the Academy." "Lavoisier, he talks about facts;" "he worships the truth." "Listen to me, my friend." "They are all the same, the Royal Academies." "They insult the liberty of the mind." "They think they are the sole arbiters of genius." "They are rotten to the core, just like every other tentacle of the King." "The people, it is they who will determine right and wrong." "Don't worry." "In my next pamphlet," "I will expose this persecutor of yours." "For years the Lavoisier's burned, chopped, melted and boiled every conceivable substance." "They'd shown that as long as one is scrupulous about collecting all the vapors, liquids and powders created in a transformation then mass is not lost." "Liquids might become gases, metals may rust, wood may become ash and smoke, but matter, the tiny atoms that make up all substances, none of it is ever lost." "The crowning glory of this opus was their remarkable use of static electricity to cause oxygen and hydrogen to recombine back into water." "What is happening?" "As the French Revolution exploded, the royal family and whole swathes of aristocrats lost their heads on the guillotine." "To the French revolutionaries of 1790," "Lavoisier meant one thing and one thing only:" "he was the despised tax collector who'd built the wall around Paris." "Lavoisier's job as a tax collector brought him under suspicion." "He was denounced by a failed scientist turned radical journalist, Jean-Paul Marat." " Ou est Lavoisier?" " Je ne sais pas!" "Lavoisier?" "Lavoisier?" "Lavoisier?" "What Lavoisier did was absolutely central to science and especially to E = mc2, because what he said is if you take a bunch of matter, you can break it apart, you can recombine it, you can do anything to it," "and the stuff of the matter won't go away." "If the mob burned Paris to the ground, utterly raised it, shattered the bricks into rubble and dust, and burned the buildings into ashes and smoke, it turns out if you put a huge dome over Paris" "and weighed all the smoke and all the ashes and all the rubble," "it would add up to the exact same weight as the original city and the air around it before." "Nothing disappears." "By the time Einstein enrolled as a physics student the first two parts of the equation" "E and m, energy and mass, were in place." "They were reveiled as the two great domains of nature." "Everything that existed fell into one of these classifications." "The laws that governed one, did not apply to the other." "But, of course, young Albert didn't care much for laws." "Good grief, Einstein, what happened to you?" "It is more than a little ironic, having been reprimanded yesterday by that idiot Professor Pernet for poor attendance, that I should, in fact, attend a practical lesson which was as long as it was boring," "and utterly pointless by the way, only to be the victim of an explosion of my own apparatus." " And so it was your own fault then?" " Thank you." "And how are you today, Fraulein Maric?" "Extremely well, Herr Einstein." "All the better for seeing you have escaped the physics laboratory with your life." "Well, in order not to alarm you any further, I pledge to forever continue my studies here at the Cafe Bahnhof, reading only the great masters of theoretical physics and eschewing the babbling nonsense of the polytechnicians." "Hah." "That's about all you ever do." "It's getting a little stuffy in here, Fraulein Maric." "Would you care to take a walk with me?" "There's something I'd like to discuss with you." "Why, Herr Einstein?" "... of course perhaps, you'd like me to tell you what you have missed in lectures this week?" "Einstein wasn't exactly a model student." "He excelled in certain subjects, especially physics and math, but he wasn't very diligent in a lot of his other classes." "He was undoubtedly very questioning, which seems to have annoyed most of his professors throughout his life." "He would pursue his fascinations with just incredible determination." "We know from his letters that Einstein, even from the age of 16, was literally obsessed with the nature of light." "Everyone he could speak to, his friends, his colleagues, even his then girlfriend, Mileva Maric, who would become his wife everyone he badgered with the question, "What is light?"" "What would I see if I rode on a beam of light?" "What?" "A beam of light?" "By what method do you propose to ride on this beam of light?" "The method is not important." "Let us just imagine we two are young, radical, bohemian experimenters, hand in hand, on a journey to the outer reaches of the universe, and we are riding on the front of a wave of light." "I really don't know what you are suggesting, Herr Einstein." "Do you wish to hold my hand or ridicule me?" "Ridicule you?" "No, never." "I merely want you to help me to understand." "What would we see, do you think, if we were together, and we sped up and up until we caught up to the front of a beam of light?" "It was Einstein's relentless pursuit of light, which would bring about a revolution in science." "With light he would reinvent the universe and find a hidden pathway that would unite energy and mass." "The term "c" in E=mc2 stands for "celeritas"." "It's Latin for "swiftness"." "It's a recognition of light's incredible speed, faster then any other known substance, 670 million mph." "Long before the 19th century, scientists had computed the speed of light, but no one knew what light actually was." "Back in England, a man we've already met was willing to make an educated guess." "After Sir Humphry Davy's death, Michael Faraday became Professor Faraday, one of the most important experimenters in the world." "The scientific establishment still found it hard to accept that electricity and magnetism were just two aspects of the same phenomenon, which Faraday called "electromagnetism"." "But now he has an even more outrageous proposal for his audience." "...invisible lines that can emanate from electricity in a wire, from a magnet, or even from the sun." "For it is my contention that light itself is just one form of these vibrating lines of electromagnetism." "For 15 years, Faraday struggled to convince the skeptics that Light was an electromagnetic wave, but he lacked the advanced mathematics to back up his idea." "Eventually, someone came to his rescue." "Professor James Clark Maxwell believed in Faraday's farsighted vision, and he had all the mathematical skill to prove it." "Maxwell and the aging Faraday became close friends." "James, James, forgive me." "A word of advice: don't get old." "Michael, how are you?" "Oh, I'm fine." "Memory isn't too good though." "Well, I thought you might like to see what I've just published." "Oh, yes, yes, splendid." "So your results show that when electricity flows along a wire what it actually does is create a little bit of magnetism." "As that magnetic charge moves it creates a little piece of electricity." "Electricity?" "Electricity and magnetism are interwoven, like a never-ending braid, so it is always pulsing forward." "That's wonderful." "Michael, Michael." "There's something very crucial in the math." "This electricity producing magnetism and magnetism producing electricity, it can only ever happen at a very particular speed." "The equations are very clear about it." "They come up with just one number, 670 million miles per hour." "I'm not sure I..." "It's the speed of light." "That is the speed of light." "You were right all along, light is an electromagnetic wave." "Maxwell had proven Faraday right." "Electricity and magnetism are just two aspects of a deeper unity, a force, now called electromagnetism, which travels at 670 million miles per hour." "In its visible form it is nothing other than light itself." "And nothing fascinated the young Einstein more than light." "We have lectures in half an hour." "Oh, let me think:" "Professor Weber and his life-draining monologue or you, Mozart and James Clark Maxwell?" "We can't." "We'll get a warning." "Our project is too precious to waste time listening to those dullards." "Come with me." "We'll read Maxwell and think about the electromagnetic theory of light." "Oh, why, my dear little Johnnie, how you enchant a lady." "She's very pretty." "Yes, but can she soar and dance like our dark souls do?" "Maxwell's equations contained an incredible prediction." "They said you could never catch up to a beam of light." "Even if you were traveling at 670 million miles an hour, you would still see light squiggle away from you at 670 million miles an hour." "Do you see how she stares at that wave?" "Yes." " You see how, for her, it is static?" " Yes." "She and the wave are traveling at the same speed." "We see the moving through the water." "But relative to her it just sits there." "So is light like that?" "Common sense would say that if you caught up to a light beam, there would be a wave of light, just sitting there." "Maybe it would be shimmering, a bit of electricity and a bit of magnetism." "So, if she was traveling alongside the light wave it wouldn't be moving." "It would be static." "But Maxwell says you can't have static light." "Maybe Maxwell is wrong." "Maybe if you catch up to light it is static," "Albert, like a wave next to a boat." "Imagine if I were sitting still and holding a mirror to my face." "And the light travels from my face to the mirror, and I see my face." "Yes." "However, if I and the mirror were traveling at the speed of light?" "You're going at the same speed as the light leaving your face?" "Exactly." "The light never reaches the mirror?" "So would I be invisible?" "That doesn't make sense." "Young Einstein was starting to realize that light was unlike any other kind of wave." "Einstein was about to enter a surreal universe where energy, mass and the speed of light intermingled in a way no one had ever suspected." "But there was one last mathematical ingredient that Einstein would need, the everyday process of squaring." "Long before the French Revolution, scientists were not sure how to quantify motion." "Equations that explained how objects moved and collided were in their infancy." "A crucial contribution to this subject would come from an unusual source." "Meet the aristocratic, 16-year old daughter of one of King Louis the XIV courtiers, Emilie Du Châtelet." "Quickly, father's coming." "Emilie du Châtelet would have a huge effect on physics in her tragically short lifetime." "Unheard of, for a woman in the eighteenth century, she would publish many scientific works, including a translation of Sir Isaac Newton's Principia, the greatest treatise on motion ever written." "Du Châtelet's translation is still the standard text in France today." "Musa, mihi causas memora?" "Muse, my memory causes...?" ""O Muse." "The causes and the crimes relate;" "what goddess was provok'd, and whence her hate;" "For what offence the Queen of Heav'n began to persecute so brave, so just a man"." "Do not be cross with your sister because she persecutes many a just man." "Only the other night Emilie silenced the Duc du Luynes when she divided a ridiculously long number in her head in a matter of seconds." "You should have seen the incredulity on their faces when they realized Emilie was correct." "Was it my sister's astounding intelligence or her boundless beauty that made their mouths gape, I wonder?" "Ah well, yes, you have a point, Monsieur." "Messieurs, I thank you for your kindness." "I fear, however, that my wit is only a curiosity to others." "If only my mind was permitted opportunity." "My dearest, Emilie." "You are blessed with intellect and courage." "Use them both and the world will fall at your feet." "In one sense, she is a woman utterly out of her true time and place." "She is a philosopher, a scientist, a mathematician, a linguist." "She demands a freedom that women didn't begin to enjoy until over 150 years later, a freedom to study science, to write about it and to be published." "Du Châtelet married a general in the French army at age nineteen and had three children." "She ran a busy household, all the while pursuing her passion for science." "She was 23 when she discovered advanced mathematics." "She enthusiastically took lessons from one of the greatest mathematicians of the day," "Pierre de Maupertuis." "He was an expert on Newton, and she was his eager young student." "It seems they had a brief affair." "But then he set off on a Polar Expedition." "Du Châtelet then fell passionately in love with Voltaire," "France's greatest poet." "A fierce critic of the King and the Catholic Church," "Voltaire had been in prison twice and exiled to England, where he became enthralled by the ideas of Newton." "Back in France, it wasn't long before he again insulted the King." "Du Châtelet hid him in her country home." "The poor little creature is devoted to him." "Isolated far from Paris, Du Châtelet and Voltaire turned her chateau into a palace of learning and culture complete with its own tiny theatre and all with the apparent blessing of her husband." "There is a great deal of myth surrounding Du Châtelet and her love life." "And most of it is very exaggerated." "But her husband did accept Voltaire into his household, and he often went to Paris on behalf of Voltaire." "He went to his publisher to plead Voltaires' case, to keep Voltaire out of jail." "And it is also true that Emilie Du Châtelet did have several affairs of a fleeting nature." "She created an institution to rival that of France's Royal Academy of Sciences." "Many of the great philosophers, poets and scientists of the day visited." "Ah, Monsieur you are young." "I hope that soon you will judge me for my own merits or lack of them, but do not look upon me as an appendage to this great general or that renowned scholar." "I am, in my own right, a whole person, responsible to myself alone for all that I am, all that I say, all that I do." "Du Châtelet learned from the brilliant men around her, but she quickly developed ideas of her own." "Much to the horror of her mentors, she even dared to suspect that there was a error in the great Sir Isaac Newton's thinking." "Newton stated that the energy of an object, the force with which it collided with another object, could very simply be accounted for by its mass times its velocity." "In correspondence with scientists in Germany," "Du Châtelet learned of another view, that of Gottfried Leibniz." "He proposed that moving objects had a kind of inner spirit." "He called it "vis viva", Latin for "living force"." "Many discounted his ideas, but Leibniz was convinced that the energy of an object was made up of its mass times its speed, squared." "Taking the square of something is an ancient procedure." "If you say a garden is "four square,"" "you mean that it might be built up by four slabs along one edge and four along the other so the total number of paving slabs is four times four, is 16." "If the garden is eight square, eight by eight, well eight squared is 64, it'll have 64 slabs in it." "This huge multiplication, this building up by squares is something you'd find in nature all the time." "Emilie, Emilie, you are being absurd." "Why ascribe to an object a vague and immeasurable force like vis viva?" "It is a return to the old ways." "It is the occult." "When movement commences, you say it is true that a force is produced which did not exist until now." "Think of our bodies, to have free will we must be free to initiate motion." "So, all Leibniz is asking is, "Where does all this force come from"?" "In your case, my dear, the force, I'm sure, is primeval." "Aaah, you're infuriating." "You hide behind wit and sarcasm." "You only think you understand Newton." "You are incapable of understanding Leibniz." "You are a provocateur." "Everything you do is about something else and makes trouble for you." "Criticize this, denounce that." "Are you capable of discovering something of your own?" "I discovered you." "Despite the overwhelming support for Newton," "Du Châtelet did not waver in her belief." "Eventually, she came across an experiment performed by a Dutch scientist," "Willem 'sGravesande that would prove her point." "'sGravesande, in Leiden, has been dropping lead balls into a pan of clay." "Dropping lead balls into clay?" "How very imaginative." "Using Newton's formulas, Monsieur Voltaire he then drops a second ball from a higher height, calculated to exactly double the speed of the first ball on impact." "So, Messieurs, care for a little wager?" "Newton tells us that by doubling the speed of the ball, we will double the distance it travels into the clay." "Leibniz asks us to square that speed." "If he is correct the ball will travel not two, but four times as far." "So who is correct?" "Messieurs, I feel Mister Newton's reputation dwindling, ever so slightly." "Oh, Maupertuis, do not succumb to her." "There is no earthly reason to ascribe hidden forces to this Dutchman's lead balls." "Well, the ball travels four times further." "Turns out Leibniz is the one who is right." "It's the best way to express the energy of a moving object." "If you drive a car at twenty miles an hour, it takes a certain distance to stop if you slam on the breaks." "If you're going three times as fast, your going sixty miles an hour, it won't take you three times as long to stop, it'll take you nine times as long to stop." "Oh." "Well, it does seem worth consideration." "Perhaps we might look over his calculations?" "I have already checked his figures." "I am sure Leibniz is correct on this point." "I intend to include a section on this matter in my book." "Really?" "Do be careful, Madame." "Do you think the Academy is ready for such an opinion?" "Quite, quite." "We really should be careful..." ""We?" I see no reason to delay." "There is no right time for the truth." "Emilie du Châtelet published her Institutions of Physics in 1740, and it provoked great controversy." "Voltaire wrote that "she was a great man whose only fault was being a woman"." "In her day that was a great compliment." "I am with child." "You are sure?" "Undoubtedly." "Two to three months." " I'm afraid..." " You are afraid?" "Well you should have..." "Oh, well, this child is obviously not mine, nor is it your husband's." "Oh, Emilie, Emilie." "Emilie Du Châtelet knew that in the 18th century, for a woman to become pregnant at the age of forty-three was really very dangerous, and all the while she was pregnant she had terrible premonitions about what was going to happen." "All her life Du Châtelet had tried to rise above the limitations placed on her gender." "In the end it was an affair with a young soldier that led to her demise." "Six days after giving birth to her fourth child she suffered an embolism and died." "Emilie du Châtelet's unwavering belief, that the energy of an object is a function of the square of its speed, sparked a debate that was as long as it was fierce." "After her death it took a hundred years for the idea to be accepted just in time for Einstein to use this brilliant insight to finally bring energy and mass together with light." "After the University Einstein had all the parts of E=mc2." "Energy, mass, the speed of light and squared were now the staples of modern physics." "But Einstein now longer had an academic position." "He'd upset so many professors that no one would write him a reference." "He accepted a low paying job in the Swiss patent office." "He and Mileva married and had a child." "The young family struggled, but none of it seems to bother Albert." "Einstein, I see you are busy as usual." "Look, Einstein, you have shown some quite good achievements." "But listen, about your promotion," "I really think it would be better to wait until you have become more fully familiar with mechanical engineering." "I'm sorry, perhaps next time." "But I wanted to hire a maid so I can get back and finish my degree." "Now I'll never pass my dissertation." "Oh, come, come, my pretty little duck." "All will be fine, you'll see." "But how will it be fine Albert?" "Do I have to just wait another year, until you are promoted?" "All will be fine." "All will be fine." "You'll see." "There really is a very charming, but kind of a self-centered streak to Einstein." "He focuses only on his particular obsessions." "If the rest of the world fits in around him, that's fine, if they can't, it doesn't bother him." "Albert, Albert, Albert." "A pretty neck and your head spins." "Besso, we must behold and comprehend the mysterious." "Well, that kind of mysterious is going to get you into trouble." "I'll tell you what is truly mysterious, the secret of a long and happy marriage." "The mathematics are fine, if a little unconventional." "But this only works for big systems." "It'll fall down when you apply it to small systems." "I disagree." "Oh, no, here we go: another grand theory by Herr Albert Einstein," "Patent Clerk, Third Class." "What would happen if one applied those formulae to electromagnetic radiation?" "Albert, you can't just borrow one bit of physics and apply it, without proper regard, to a completely different area." "Why not?" "Albert, I know you like the grand linkages, the big theories, but wouldn't things be better all'round if you just got going in some small area, got a university post." "Get a decent wage, for God's sake." "At least Mileva could study again." "Then she'd be happy and you'd be happy." "Ah, the vulgar struggle for survival, food and sex: spoken like a true bourgeois." "Besso." "I want to know how God created this world." "I am not interested in this or that phenomenon, in the spectrum of this or that element." "I want to know his thoughts." "The rest are details." "Yes, but you can't feed your children on his thoughts, Bertie." "So it turns out Einstein was going for walk with his very close friend Michele Besso." "They'd studied physics together and talked about physics and philosophy for years and years." "They were very close." "They had cornered the question of light from every possible angle." "As Einstein was ruminating on how long it would take light to reach him from clocks at different distances, he had a monumental insight." "Thank you, thank you!" "I have completely solved the problem." "Albert?" "What Einstein did was completely turn the problem on its head." "Other scientists had found it impossible to accept Maxwell's idea that light would always move away from you at 670 million miles an hour, even if you, too, were traveling really fast." "But Einstein just accepted that as a fact:" "light's speed never ever changes." "Then what he did was bend everything we know about the universe to fit light's fixed speed." "What he discovered was that to do that you have to slow down time." "His extraordinary insight is that time... as you approach the speed of light, time itself will slow down." "It's a monumental shift in how we see the world." "The instant, the very instant when Einstein had this brilliant insight that time could slow down,well the floodgates began to open." "You see, before then people had assumed that time was like a wristwatch on God's hand, that it beat at a steady rate throughout the universe no matter where you were." "Einstein said no, that the tick, tick, tick of this wristwatch was actually the click, click, click of electricity turning into magnetism turning into electricity in other words, the steady pace of light itself." "1905 was a miraculous year for Einstein and for physics." "He had an unbelievable outpouring of creativity." "It starts with his publication of a paper on how to work out the true size of atoms." "Two months later is the publication of his paper on the nature of light." "That's what will earn him the Nobel Prize." "The third paper, only a month later is on how molecules move when heated, and that finally ends the debate on whether atoms really exist." "The fourth paper is published at the end of this half-year period." "In it Einstein sets out his theory of light, time and space." "It was the "Theory of Special Relativity" that changed the way we see the world." "In Einstein's new world, the one true constant was not time or even space, but light." "But Einstein's miracle year was not over;" "in one last great 1905 paper, he would propose an even deeper unity." "As he computed all the implications of his new theory he noticed another strange connection, energy and mass were being forced together by light's incredible but fixed speed." "Einstein realizes that the speed of light is kind of like a cosmic speed limit, nothing can go faster." "So imagine we have a train charging along." "And let's say it's getting up to the speed of light, and we're stuffing more and more energy in trying to get it to go faster and faster," "but it's still bumping up against the speed of light." "So all this energy, where does it go?" "It has to go somewhere." "Amazingly it goes into the object's mass." "From our point of view, the train actually gets heavier." "The energy becomes mass." "It's an incredible idea." "Even Einstein is amazed by it." "Look." "I think I have found a connection between energy and mass." "If I am right then energy and mass are not absolute." "They are not distinct." "They can be converted into one another." "Energy can become mass, and mass can become energy, and not just energy equaling mass." "Energy equals mass times the square of the speed of light." "Would you like me to check your mathematics?" "Einstein sent his fifth great 1905 paper for publication." "In three pages he simply stated that energy and mass were connected by the square of the speed of light:" "E=mc2." "With four familiar notes in the scale of nature, this patent officer had composed a totally fresh melody, the culmination of his 10 year journey into light." "Here we are, for thousands of years, thinking that over here is a world of objects, of matter, and over there is an entirely separate world of movement, of forces, of energy." "And Einstein says "No." "They are not separate." "Energy can become mass." "And crucially, mass can also become energy"." "There is a deep unity between energy, matter and light." ""E = mc2."" "That equation shows that every piece of matter in our universe has stored within it a fantastic amount of energy." "The speed of light for example is about 300 million meters per second," "You multiply that by itself and you get 90 quadrillion." "So, in other words, what is matter?" "In some sense, matter is nothing but the condensation of vast amounts of energy." "So, in other words, if you could unlock, somehow unlock, all the energy stored within my pen, that would erupt with a force comparable to an atomic bomb." "After Einstein's fifth great 1905 paper, physicists no longer spoke of mass or energy." "They are now the same thing to us." "Probably the most miraculous year in human science ends in silence." "The articles are published to resounding... nothing." "I think the Gods are laughing at me." "Then slowly it starts:" "a letter here, a letter there." "For four years Einstein answered each inquiry dutifully, trying to explain his difficult, complex ideas to a confused physics community." "I love the idea that life just went on as normal." "Here are these universe-changing papers circling around, and the world is struggling to come to terms with them." "Einstein had a fan club of just one." "Luckily, it happened to be the most important living physicist." "Einstein, Einstein." "Max Planck has sent someone to see you." " Max Planck?" " Yes, he has sent his assistant." "He's here to see you." "Max Planck encourages the world's most eminent physicists to take Einstein seriously." "After four years of waiting he was appointed Professor of Physics at Zurich University." "From there his career was meteoric." "He was made Professor of Physics in Berlin, achieved world renown and became a household name." "He was the undisputed father of modern physics." "But Einstein's success was the downfall of his marriage." "In 1919, he divorced Mileva and married his cousin." "His fame led to numerous affairs." "E = mc2 became the Holy Grail of science." "It held out the promise of vast reserves of energy locked deep inside the atom." "Einstein suspected that it would take a hundred years of research to unlock it." "But he hadn't banked on the Second World War and the genius of a Jewish woman in Hitler's Germany." "Einstein had astounded the world with E=mc2." "It said that every single object in the Universe is just a piece of immensely compressed energy." "The ammount of energy in an object is equal to its mass times c, the speed of light, squared." "In other words, its energy is equal to its mass times 90 billion billion." "But it would not be Einstein who would unlock this vast energy." "Twenty-eight year old Austrian Lise Meitner was painfully shy." "Despite her anxiety, the young Doctor of Physics arrived in Berlin determined to pursue a career in the exciting, new field of radioactivity." "Unfortunately, in 1907, German universities did not employ women graduates." "Luckily, one man came to her aid." " Fraulein Meitner?" " Yes." "Otto Hahn." "I'm a researcher in the Chemistry Institute." "Professor Planck suggested I..." "Ah yes, Herr Hahn." "I have read both your papers on Thorium and on Mesothorium." "Dr. Planck suggested that I..." "Yes, he suggested that" "I speak to you." "I need someone to collaborate with." "I think I could really help with the physical analysis." "And the mathematics?" "Yes, yes, and the mathematics." "Studying radioactive atoms has become so much a collaboration between chemistry and physics these days." " Yes, yes." " I'll ask Fischer for a laboratory then." " Excellent." " I'll speak to you soon." "Lise Meitner had just taken the first step on a journey that would irrevocably change world history." "For her, it would be a road marked with success and renown, but also terror and betrayal." "At this time, not a lot was known about the atom." "At first people thought it was like a miniature cellular system, there's a solid nucleus of the center and electrons would spin around it, sort of like planets around our sun." "A little later, some researchers proposed that the nucleus itself wasn't a solid chunk but was made up of separate particles, of protons and neutrons." "But then, in what are called radioactive metals, things like radium and uranium, the nucleus itself seemed to be unstable, leaking out energy and particles." "Perhaps this was an example of E = mc2, the mass of a nucleus turning into energy?" "Meitner and Hahn's collaboration to unlock the secrets of the atom, started out on an extremely unequal footing." "He was given a laboratory." "She was forced to work in a woodshop." "I see you haven't set your hair on fire?" " Herr Hahn?" " The boss." "He thinks that if he lets women into the Chemistry Institute they'll set their hair on fire." "Ah, so his beard must be fireproof." "Good day, Herr Hahn." "Good day." "You see." "I am nonexistent to this place." "At least physicists recognize me for my abilities." "Ah, yes, where would we chemists be without the steadying hand of the physicist?" "It took years, but Lise lost her shyness eventually." "In 1912, she and Hahn moved to the brand new Kaiser Wilhelm Institute for Chemistry where their status was really that of equals." "Lise became the first woman in Germany to have the title of Professor." "Lise, I have news." "You remember the art student I told you of?" "Yes." "Edith." "Yes, well, I have asked her to marry me, and she has accepted." "Ah." "Doctor Hahn, congratulations." "Yes, well, I wanted you to be the first to know." "I'm very pleased for you, very pleased." "Lise Meitner was warm hearted by nature, she had many friends, and she may have wanted to have a closer relationship with Otto." "But it really does seem that physics was Lise's first love, maybe even her passion." "The 1920s and '30s were the golden age of nuclear research." "The largest known nucleus at the time was that of the Uranium atom containing 238 protons and neutrons." "Meitner and Hahn were leading the race to see if even bigger nuclei could be created by adding more neutrons." "The nucleus is our focus." "The nucleus, made up of protons and neutrons." "Now, the largest nucleus that we know is that of the Uranium atom." "Its nucleus is a tightly packed structure of 238 protons and neutrons." "The thrust of our work is to try to fire neutrons into this huge structure, and if we can get a neutron to stick in here, it will be a breakthrough." "Meitner may have been on the brink of a major discovery, but Germany in the 1930s was a dangerous place to be, even for a world-class scientist." "The Jewess endangers our Institute." "Unlike many other jewish scientists, Meitner refused to leave her work." "By 1938, her situation had become untenable." "The pressure on them all was unbearable." "Hahn, who was known for its anti-nazi views, did his best to protect her." "At least, initially." "I need to talk to you about Lise." "Ah, not now, I'm too busy." "We have to protect her." "Oh..." "How?" "What can we do?" "The situation is the way it is." "Who knows what could happen next?" "She can't stay." "Its just not tenable." "But she hasn't got a visa or even a valid passport." "And she may soon be forbidden to leave Germany." "We can't harbor a Jew." "If she stays, the regime will shut us all down." "Lise!" "Horlein demands that you leave." "You can't throw her out." "Horlein says you should not come into the Institute any more." "When it became clear that Meitner would be dismissed and probably arrested, physicists all around Europe desperately wrote letters inviting her to conferences, to give her an excuse to leave Germany." "The Nazis refused her permission." "In July of 1938, a friend, a Dutch colleague traveled to Berlin and illegally took Lise back with him on a train to Holland." "The trip was so frightening that at one point she begged to go back." "Despite the great danger, she got through." "She had lost everything: her home, her position, her books, her salary, her pension, even her native language." "She had been cut off from her work just at the time when she was leading the field and was on the brink of a major scientific discovery." "No matter the privations she suffered," "Lise was still thinking of physics." "Amazingly she and Hahn were able to collaborate by letter." "I hope, my dear Otto, that after 30 years of work together and friendship in the institute, that at least the possibility remains that you tell me as much as you can about what is happening back there." "Lise was invited by an old student friend to spend Christmas on the west coast of Sweden." "Her nephew, Otto Robert Frisch, who was also a physicist, came to join her there." "Aunt?" "Aunt?" "Aunt?" "Lise?" "How are you, my dear?" "Merry Christmas?" "Aunt?" "I need your help, come on let's go out." "But, I was hoping you'd help me." "Back in Berlin, Hahn was getting strange results." "He found no evidence to suggest that bombarding the uranium nucleus with neutrons had caused it to increase in size." "In fact, his experiments seemed to be contaminated with radium, a smaller atom." "He desperately needed Meitner's expert analysis." "From afar, she was starting to suspect that something very different was happening in their experiment." "Hahn and Strassman are getting some strange results with the uranium work." "Really?" "A couple of months ago Hahn told me that they were finding radium amongst the uranium products." "We are looking for a much bigger element, and here we are finding something much smaller." "I urged Hahn to check again, it couldn't be radium." "And now he writes to me and tells me that it's not radium, it's barium." "But that's even smaller." "Exactly." "Hahn is sure that it's another error, but I don't know any more." "It is at least possible that barium is being produced." "So Hahn still needs you to interpret the data." "It is my work too, you know." "Exactly." "Well, I can't be there, can I?" "Come on, let's walk." "Surely, he's made a mistake, hasn't he?" "He hasn't done what you told him to." "My darling, Robert, he may not be a brilliant theorist, but he's too good a chemist to get this wrong." "If you imagine a drop of water, a big drop, it's unstable, on the verge of breaking apart." "It turns out that a big nucleus like uranium is just like that." "Now for four years Meitner and Hahn and all other physicists had thought that if you pump more neutrons into this nucleus, it'll just get bigger and heavier." "But suddenly Meitner and Frisch, out in the midday snow, realized that this nucleus might just get so big that it would split in two." "If the nucleus is so big that it has trouble staying together, then couldn't just a little tiny jog from a neutron and..." "Yes, but if the nucleus did split, the two halves would fly apart with a huge amount of energy." "Where's that energy going to come from?" "How much energy?" "Well, we worked out that the mutual repulsion between two nuclei would generate about 200 million electron volts." "But something has to supply that energy." "Wait, let me do a packing fraction calculation." "The two nuclei are lighter than the original nucleus of the uranium by about one-fifth of a proton in mass." "What?" "So some mass has been lost?" "Einstein's E = mc2?" "If we multiply the lost mass by the speed of light squared we get... 200 million electron volts." "He's split the atom." "No, no, no." "You've split the atom." "It was an amazing discovery." "Of course in the laboratory we are talking about tiny amounts of uranium and correspondingly tiny amounts of energy." "But the point is that the amount of energy released was relatively large and that came from the mass of the uranium itself." "The energy released was entirely consistent with Einstein's equation," "E=mc2." "Meitner and Frisch published the discovery of what they called nuclear fission to great acclaim." "But betrayal awaited them." "Otto Hahn was under pressure from the Nazi regime to write his Jewish colleague out of the story." "He alone was awarded the 1944 Nobel Prize for the discovery." "In his speech he barely mentioned the leading role of Meitner." "Bizarrely even after the war," "Hahn maintained it was he and not Meitner who had discovered nuclear fission." "Lise Meitner was betrayed, refused a Nobel prize she deserved, but her work was to have a far greater legacy." "With E=mc2 she may have only broken apart only a handful of atoms, but the genie was out of the bottle." "Lise Meitner had shown that Einstein's E=mc2 was true, energy could be released from matter." "But neighter of this pure scientists had foreseen the consequences of their discoveries." "In 1942, an intense effort to build an atom bomb was begun." "All over America, secret installations sprang up under the code name" ""The Manhattan Project"." "Meitner was asked to join the Manhattan project, and she refused." "She refused to have anything to do with the atomicic bomb." "But Robert Frisch was different." "He was an important member of the team, because he was convinced of the need to beat the Nazis in a nuclear arms race." "The atomic bombs dropped on Hiroshima and Nagasaki demonstrated the terrible destructive power of E = mc2." "A few pounds of uranium and plutonium were detonated, splitting apart their atoms and releasing vast amounts of energy." "While the pure inquisitiveness of the world's most gifted scientists ironically had brought humanity a weapon of mass destruction, the equation is now used to ask the biggest question of all:" "Where did we come from?" "Today's generation of physicists see E=mc2 in action every day." "In huge accelerators like this atomic particles are fired at almost the speed of light." "As they travel more and more energy is pumped into them." "Just as Einstein predicted, they grow in mass." "These are the exact conditions that existed just after the Big Bang." "E = mc2 actually tells us how the Big Bang itself happened." "In the first moments of creation, the universe was this immensely dense, immensely concentrated eruption of energy." "As it rushed apart and expanded, huge amounts of energy or "E"" "were converted into mass or "M"." "Pure energy became matter, it became the particles and atoms, and it eventually formed the first stars." "Our sun is a huge furnace, floating in space, and it's powered by E = mc2." "Now it turns out, every second, four million tons of solid mass of the sun, disappears." "It comes out as energy." "Not just a little bit of energy, it's enough to light up our entire solar system, make the solar system glow with heat and light." "And not only do stars emit energy, in accordance with E = mc2, the whole process actually creates life itself." "Eventually, a massive star dies, the debris floats around, clusters together, gets pulled into the orbits of another star and becomes a planet." "We humans and the earth we stand on are made of stardust;" "we are a direct product of E = mc2." "Einstein built on the work of those who went before him." "Now others have taken his equation on further." "E=mc2 is being used to delve back into time, to figure out exactly how our universe started and, if in fact, it will one day end." "Somewhere out there is yet another genius with the answer."
