“Whether the theory ultimately proves to be correct or not, it claims attention as being one of the most beautiful examples of the power of general mathematical reasoning,” he wrote in his account of general relativity, the first book on the subject to appear in English. With Eddington acting as Einstein's translator and champion, the two were often linked in people's minds. An accomplished popularizer of science, Eddington said that Einstein had taken “Newton's plant, which had outgrown its pot, and transplanted it to a more open field.” Eddington was becoming so proficient at explaining relativity that “people seem to forget that I am an astronomer and that relativity is only a side issue,” he lamented after one wearying interview with reporters. Arthur Eddington (AIP Emilio Segrè Visual Archives) For Eddington to serve as a spokesman for a radical new theory was somewhat out of character for him.

Because of various technical problems with the Sobral scope, including a blurring of its images, the British team decided to downplay that instrument's results. Eddington admitted he was unscientifically rooting for Einstein, but his instincts to reject the astrographic telescope results turned out to be good in the end. Campbell headed up another solar-eclipse expedition in 1922, which arrived at similar results and further confirmed Einstein's theory. When asked what he had been expecting, Campbell replied in all seriousness, “I hoped it would not be true.” Relativity's thoroughly new vision of space and time, coupled with its complexity, made even several leading scientists reluctant to accept its predictions.

The armistice opened up a grand opportunity for Eddington to help test Einstein’s theory and thus rekindle the trust between scientists of their respective nations. Eddington and Frank Watson Dyson, Astronomer Royal of Britain, realized that an ideal opportunity to measure gravitational light bending would arise on May 29, 1919. On that day, a solar eclipse would occur over part of the Southern Hemisphere just when the Sun was passing in front of the Hyades star cluster, a particularly bright formation. Dyson appointed Eddington to be the organizer of a project to 66 The Crucible of Gravity observe the eclipse, a move that helped save the latter from internment as a conscientious objector.15 In January 1919, to set a baseline for the observation, Eddington carefully measured the unaltered positions of the Hyades stars.

It was forced to cede some of its territory, limit the size of its army, and pay extensive reparations—leading to much resentment and economic depression that would contribute to the rise of the Nazis. During the war, Einstein had little chance to test his hypothesis about the gravitational bending of starlight by the Sun. Finlay-Freundlich’s inability to complete his expedition was a great disappointment to him. Einstein quietly began to correspond with a British astronomer, Arthur Eddington, who was keenly interested in verifying Einstein’s theory. According to several widely reported stories, Eddington was known at the time as one of the few people who truly understood general relativity.14 A Quaker and a pacifist, Eddington, like Einstein, was opposed to the war and in favor of international scientific cooperation.

Again, scientists are readily observed following this advice—but again, it is not always feasible. Solar eclipses are rare enough; what made Eddington’s 1919 eclipse rarer still was the sun’s position, at the time of totality, in the center of a field of relatively bright stars. As Eddington pointed out when touting the experiment, this happy alignment “would not occur again for many years.” He might have wanted to go back for another round of stellar photography, but he could not—so he found other ways to press his case against the Brazilian astrographic and in favor of Einstein. Eddington’s course of action was unconstrained not because he disdained the rules of scientific thought but because the complexities and difficulties of empirical investigation—of making precise measurements of small or barely accessible quantities—meant that he had no rule capable of telling him how to interpret his photographic plates.

To better understand scientific objectivity and its self-imposed limits, let’s go back to a quintessential case of subjectivity, embarking one last time with Eddington on his expedition to test Einstein’s theory of general relativity by observing the 1919 total eclipse of the sun. THREE TELESCOPES, you will recall, were trained on the eclipse. The instrument on the African island of Príncipe barely saw the sun through the clouds. The two telescopes in Brazil gave conflicting testimony: one, the 4-inch telescope, saw light bent roughly as Einstein predicted, but the other—the Brazilian astrographic telescope—saw the bending predicted by Newtonian physics. Eddington discounted the results from the Brazilian astrographic on the grounds that its photographs were out of focus, while lavishing great care on his own equally obscure Príncipe photographs, teasing a pro-Einstein result out of the murk.

CHAPTER 2: HUMAN FRAILTY 42 by a young Karl Popper: As related in the previous chapter, the eclipse experiment and other tests of relativity directly inspired Popper’s idea of falsification. Thus, not only was the experiment in the Popperian mold; it molded Popper himself. 45 “the logic of the situation does not seem entirely clear”: Campbell is quoted on p. 78 of Earman and Glymour, “Relativity and Eclipses,” my principal source on criticisms of the eclipse experiment. A defense of Eddington’s neglect of the Brazilian astrographic plates is mounted by the physicist Daniel Kennefick in “Testing Relativity from the 1919 Eclipse.” Kennefick clearly explains how a “change of scale” would create a systematic error, but he does not address the curious fact that Eddington and his coauthors make no attempt to convince their readers that such a change had occurred, rather than there having been a simple loss of focus that would not create any systematic bias in the astrographic measurements.

On May 29 of each year the sun is positioned in front of an exceptionally dense group of bright stars—the Hyades cluster. That wouldn’t usually help anyone, for without a solar eclipse occurring on that particular 209 till the end of time date, there would be no chance to see how that rich field of stars gets their light bent around the sun. The glare from the daytime sun would overwhelm that small effect. But in 1919 there was going to be an eclipse, precisely on May 29. As Eddington innocently noted: “Attention was called to this remarkable opportunity by the Astronomer Royal [Frank Dyson] in March 1917; and preparations were begun. . . .” What Eddington neglected to mention was that he would have been thrown into prison if he didn’t go.

Freundlich was hopeful again. A great new eclipse expedition was being planned, for 1919. If conditions allowed international travel, he’d finally be able to prove what he could do. In November 1918 World War I ended. There were no obstacles to a German national traveling now! It’s not recorded what Freundlich felt as the great expedition set out, but we know exactly where he was when the results came through. He read it in the newspaper, back in Berlin. He hadn’t been invited along. In fact, it was a cool Englishman we’ve already met who led the team. Arthur Eddington wore small metalrimmed glasses, was medium height and barely medium weight, and spoke in sentences that tapered off whenever he had to pause for thought, which was fairly often.

In a wonderful demonstration of mock hubris, Einstein answered: ‘Then I would feel sorry for the Good Lord. The theory is correct anyway.’ Figure 28 Albert Einstein, who developed the theoretical framework of general relativity, and Sir Arthur Eddington, who proved it by observing the 1919 eclipse. This photograph was taken in 1930, when Einstein visited Cambridge to collect an honorary degree. Einstein’s Universe Newton’s theory of gravity is still widely used today to calculate everything from the flight of a tennis ball to the forces on a suspension bridge, from the swinging of a pendulum to the trajectory of a missile.

The Glass Universe: How the Ladies of the Harvard Observatory Took the Measure of the Stars by Dava Sobel

The idea of relativity put forth by Albert Einstein in 1915 was changing the nature of space from a passive container of the stars to a fabric warped by the stars’ presence. Einstein’s German roots and the course of the Great War at first slowed the theory’s acceptance, but the English pacifist Arthur Stanley Eddington tested its validity during the May 29, 1919, total solar eclipse, which he observed from the African island of Príncipe. It was an eclipse expedition even Pickering would have approved. The stunning results, announced in November 1919, demonstrated that light waves indeed felt the effect of gravity—and by the amount Einstein had predicted. The erudite Eddington expressed the findings in poetry as well as prose, borrowing the rhythm of the Rubaiyat of Omar Khayyam: “Oh leave the Wise our measures to collate / One thing at least is certain, light has weight / One thing is certain and the rest debate / Light rays, when near the Sun, do not go straight.”

He was the first, in 1872, to capture the spectrum of a star on film, and followed that feat by imaging the faint stars in the Orion Nebula in 1882. Sir Arthur Stanley Eddington (December 28, 1882–November 22, 1944), one of the first to appreciate Einstein’s theories, traveled to Príncipe Island, off the west coast of Africa, for the 1919 total solar eclipse, and returned with proof of general relativity. The leader in efforts to describe the internal constitution of the stars, Eddington was knighted in 1930. Priscilla Fairfield (later Bok) (April 14, 1896–November 19, 1975) taught astronomy at Smith College while measuring the widths of spectral lines on plates at Harvard.

He was one of the few scientists who could work on the experiments because, as a Quaker, he was registered as a conscientious objector. Unknown to most of his colleagues, Eddington had used his reputation to contrive the media hullabaloo that followed the announcement in November 1919 that the solar eclipse results supported the prediction of Einstein’s theory rather than Newton’s.16 Dirac attended his lectures and, like most people who first encountered him through his dazzling prose, was disappointed to find that he was an incoherent public speaker who had the habit of abandoning a sentence, as if losing interest, before moving on to the next one.17 But Dirac admired Eddington’s mathematical approach to science, which would become one of the most powerful influences on him.

But then, moments after the moon’s shadow came speeding across the landscape and totality began, a hole opened up in the clouds around the sun, and the camera shutters were triggered. The results of Eddington’s expedition, and of a second eclipse observation conducted at Sobral, Brazil on the same day, were presented by the Astronomer Royal at a meeting of the Royal Society in London on November 6, 1919, with Newton’s portrait looking on. They were positive: The light rays coming from the stars of the Hyades were found to be offset to just the degree predicted in the theory. When Einstein received a telegram from Lorentz announcing the outcome of the Eddington expedition, he showed it to a student, Ilse Rosenthal-Schneider, who asked, “What would you have said if there had been no confirmation?”

The theory was beautiful, but was it true? Einstein, having been to the mountaintop, felt supremely confident on this score. General relativity explained a precession in the orbit of the planet Mercury that had been left unaccounted for in Newtonian mechanics, and he did not doubt it would survive further tests as well. As he wrote his friend Besso, “I am fully satisfied, and I do not doubt any more the correctness of the whole system…. The sense of the thing is too evident.”41 The wider scientific community, however, awaited the verdict of experiment. There would be a total solar eclipse on May 29, 1919, at which time the sun would stand against the bright stars of the Hyades cluster.

Conservation of mass was a central tenet of physics. Eddington wondered whether a theory published by a brilliant physicist he greatly admired could shed light on the puzzle. It said that mass and energy were different sides of the same coin. Mass could become energy, and energy could become mass. It was a wild idea. Impressively, the physicist in question had published this theory along with three others that challenged fundamental concepts in physics in 1905. His name was Albert Einstein.11 The Secrets of Atomic Energy The theory of Einstein’s that Eddington had in mind to explain the minute differences in mass of atoms said that the relationship between an object’s mass, when it is not moving, and its energy is E=mc2 where E is energy, c is the speed of light (a gut-wrenching 300 million meters, almost a billion feet, per second), and m is the mass difference that Aston found.

If it happened in any other way we’d immediately know there was something wrong. * * * This phrase was first used by the British physicist Sir Arthur Eddington in the early twentieth century to describe this deceptively simple and yet profound quality of our universe: it always seems to run in a particular direction. Eddington was instrumental in bringing Einstein’s theory of relativity to the English-speaking world during the First World War, and also one of the first scientists to directly confirm the findings of relativity when he led an expedition to observe the total solar eclipse on 29 May 1919. In 1928 he published The Nature of the Physical World, in which he introduced two great ideas that have endured in popular scientific culture to this day.

Vulcan was supposedly first sighted by amateur astronomer Lescarbault on 26 March 1859, but further observations were inconclusive and Vulcan was later proved to be a ghost planet. SCIENCE PHOTO LIBRARY EINSTEIN’S THEORY OF GENERAL RELATIVITY German-born physicist Albert Einstein (left) created the famous Theory of General Relativity. British astrophysicist Sir Arthur Eddington (right), later put this theory to the test and confirmed its accuracy. ROYAL ASTRONOMICAL SOCIETY / SCIENCE PHOTO LIBRARY Einstein would have loved the Vomit Comet. The fact that the effects of gravity can be completely removed by falling freely in a gravitational field was, for him, the thought experiment that led to his theory of General Relativity. How wonderful it would have been for him to experience it as I did!

His English teacher urged him to read about science outside the classroom, especially the popular books by the Cambridge physicist Arthur Eddington, the cosmologist James Jeans, and Albert Einstein. One of Eddington’s tales had unfolded on May 29, 1919, ten years to the day before Higgs was born.19 Eddington had cooked up a brilliant plan. He realized that nature provided a way of testing Einstein’s theory of general relativity, which said massive objects created gravity by curving space around them. Eddington promptly set sail for the tiny island of Principe off the west coast of Africa and arrived in time to witness a total eclipse of the sun. The sun has more mass than anything else in the solar system. If it didn’t, the planets would orbit some other celestial body.

Later that year, before LEP switched on, the British prime minister, Margaret Thatcher, gave a speech at the Royal Society in London, the most prestigious scientific organization in the country. She spoke wistfully of Arthur Eddington, whose stories Peter Higgs had read as a schoolboy. Eddington had chosen the Royal Society as the venue in which to describe his 1919 expedition to the west coast of Africa to prove Einstein right by watching starlight bend around the sun. “When Arthur Eddington presented his results to this society in 1919 . . . it made headlines,” Thatcher said. “Many people could not get into the meeting, so anxious were the crowds to find out whether the intellectual paradox of curved space had really been demonstrated.

If it didn’t, the planets would orbit some other celestial body. Eddington’s idea was that if the sun really curved space, the effect should reveal itself as a shift in the usual positions of the stars that became visible when the moon briefly blotted out the sun during an eclipse. The stars hadn’t moved, of course, but the light coming from them would follow the curvature of space around the sun, making them look as though they had. Eddington’s observations were published a year later and made headlines around the world as the first compelling evidence for Einstein’s theory. Higgs read voraciously. The stories Einstein, Eddington, and the others told gripped his imagination, though he was later dubious of some of Eddington’s work.

Several twentieth-century thinkers sacrificed their reputations on that altar, most notoriously Arthur Eddington. In spirit Eddington was a Pythagorean, a man who preferred to believe the world sings the unheard music of whole numbers. Eddington claimed that the fine-structure constant was exactly 1/136. He supplied an elaborate rationale that mystified all who read it. Unfortunately for Eddington, the constant is much closer to 1/137. When better measurements established this beyond dispute, Eddington admitted his mistake. The fine-structure constant, he said, is exactly 1/137. Still better measurements showed that the constant was 1/137.0359991… and definitely not the inverse of any whole number.

But there are many ways for polls to be skewed and for observations to be distorted by selection effects. British physicist Arthur Eddington gave a classic example in his 1939 book, The Philosophy of Physical Science. Wanting to know the size of the smallest fish in a pond, you get a net and scoop up a hundred random fish, measuring each carefully. The smallest fish of the hundred is six inches long. It is easy to jump to the conclusion that fish smaller than six inches are rare or nonexistent. Nope, runs Eddington’s punch line. It turns out the net can collect fish six inches or longer only. All smaller fish slip through the mesh.

Schrödinger’s research in Graz was also the kind of thing that Grand Old Men with established reputations, tenured posts, and guaranteed pensions indulge in. He became fascinated by the cosmological ideas of Arthur Eddington (1882–1944), a British Grand Old Man whose illustrious career had included explaining the general theory of relativity to the English-speaking world and testing Einstein’s theory by making observations of the stars during a solar eclipse in 1919. He was a great popularizer of science, and intrigued by the puzzle of how to reconcile the general theory with quantum mechanics. But by the 1930s he was in his scientific dotage.

The Last Stargazers by Emily Levesque

• • • The phrase scientific expedition tends to conjure up mental images of turn-of-the-century explorers doggedly trekking through the unexplored wilderness with only a team of horses, a shotgun, and their wits. It’s true that eclipse observations have included some famous historical adventures, but it’s also equally true that these types of adventures persist even today. Eclipse expeditions from previous centuries have filled entire books, including David Baron’s American Eclipse, recounting a worldwide Gilded Age scramble to study the solar eclipse that crossed North America in 1878. The most scientifically famous eclipse observation is undoubtedly Arthur Eddington’s expedition in 1919 to test Albert Einstein’s theory of general relativity. According to Einstein, the sun should “lens” background stars as it passes in front of them, bending their light thanks to the effects of the sun’s gravity on space-time and causing them to appear at a slightly different place in the sky.

The problem with testing this theory is that normally, the sun is so bright, it outshines the light of all the other stars in the sky. An eclipse would solve this, handily blocking the sun and allowing Arthur Eddington to measure the position of nearby stars. He just needed to pack up the cutting-edge astronomical equipment of 1919 and get into the path of the eclipse. In 2017, many normally quiet corners of the United States found themselves overrun with astronomy enthusiasts as they crammed themselves, their cars, and their cameras into the path of the solar eclipse. Still, a traffic jam in Wyoming isn’t quite as rough as what Eddington’s 1919 trip entailed. More than two months before the May 29 eclipse, he sailed from England to Príncipe Island off the coast of western Africa, toting a huge telescope borrowed from an observatory in Oxford and a slew of fragile glass photographic plates.

In some distant future, if we wind up in some sort of interstellar travel network with communities of intelligent friendly aliens, Earth’s solar eclipses would probably function as a planetary tourism draw in the same way that the Grand Canyon draws people to Arizona. There was also another layer of incredible serendipity thrumming under the surface on that August day during the eclipse, although only a relatively small handful of people knew about it at the time. It was the reason I’d pulled out my phone and started poking at the internet shortly after the eclipse had completed, admiring heaps of totality photos on social media from astronomer friends scattered around the country but also keeping one eyeball on my email.

What might happen to it then was first understood only at the end of the 1920s. In 1928 an Indian graduate student, Subrahmanyan Chandrasekhar, set sail for England to study at Cambridge with the British astronomer Sir Arthur Eddington, an expert on general relativity. (According to some accounts, a journalist told Eddington in the early 1920s that he had heard there were only three people in the world who understood general relativity. Eddington paused, then replied, “I am trying to think who the third person is.”) During his voyage from India, Chandrasekhar worked out how big a star could be and still support itself against its own gravity after it had used up all its fuel.

They therefore change their apparent position relative to other stars. FIGURE 2.9 It is normally very difficult to see this effect, because the light from the sun makes it impossible to observe stars that appear near to the sun in the sky. However, it is possible to do so during an eclipse of the sun, when the sun’s light is blocked out by the moon. Einstein’s prediction of light deflection could not be tested immediately in 1915, because the First World War was in progress, and it was not until 1919 that a British expedition, observing an eclipse from West Africa, showed that light was indeed deflected by the sun, just as predicted by the theory.

And even if every star managed to lose enough mass to avoid collapse, what would happen if you added more mass to a white dwarf or neutron star to take it over the limit? Would it collapse to infinite density? Eddington was shocked by that implication, and he refused to believe Chandrasekhar’s result. Eddington thought it was simply not possible that a star could collapse to a point. This was the view of most scientists: Einstein himself wrote a paper in which he claimed that stars would not shrink to zero size. The hostility of other scientists, particularly Eddington, his former teacher and the leading authority on the structure of stars, persuaded Chandrasekhar to abandon this line of work and turn instead to other problems in astronomy, such as the motion of star clusters.

Davis was aware that neutrinos should be an essential byproduct of how the Sun generates energy, thanks to astrophysicists who had figured out the Sun’s inner workings in the preceding decades. The first crucial insight on solar energy production came in 1920 from the British astronomer Arthur Eddington, who suggested that nuclear reactions are responsible. One of Eddington’s Cambridge colleagues had found that a helium atom is slightly less massive than four hydrogen atoms combined. Eddington proposed that as four hydrogen nuclei fuse to make one helium nucleus in the Sun’s core, the small mass difference would be converted into energy, according to Einstein’s equation E=mc2. It was a stroke of brilliance on Eddington’s part, but he didn’t work out the details of the mechanism.

Sometimes experiments provided dramatic confirmation of a theoretical prediction, as when astronomers observed during a solar eclipse in 1919 that the Sun’s gravity could bend the light from a distant star, just as Einstein’s general theory of relativity had anticipated. On other occasions, the application of a new theory led to a satisfactory explanation of experimental data. For example, Bohr used the concept of quantized energy to account for the spectral lines produced by hydrogen atoms absorbing light: he suggested that the lines resulted from electrons jumping between fixed orbits around the atomic nucleus. Einstein himself had used the quantum hypothesis to explain how shining light on certain materials would release electrons from that material.

He was favorably inclined toward neutrinos at first, and praised Fermi’s theory of beta decay in a letter to a colleague in 1934, in which he noted that “neutrinos seem to provide the only escape from nonconservation of energy and until something else turns up one should not be unsympathetic to them.” Barely two years later, he seemed to have had a change of heart, dismissing the neutrino as an “unobservable particle.” By the end of the 1930s, other scientists shared Dirac’s doubts about Pauli’s neutrino hypothesis. The British astrophysicist, expositor of relativity theory, and science popularizer Arthur Eddington reflected the skepticism of the time when he noted in his book The Philosophy of Physical Science: “Just now nuclear physicists are writing a great deal about hypothetical particles called neutrinos supposed to account for certain peculiar facts observed in beta-ray disintegration … I am not much impressed by the neutrino theory.

A total solar eclipse was to take place on May 29, 1919. Conveniently, it would occur in front of a rich cluster of stars known as the Hyades, offering an excellent opportunity to measure any defection of starlight by the Sun’s gravity. Less conveniently, the total eclipse could only be seen from the tropics. So the English astrophysicist Arthur Eddington mounted an expedition to the island of Principe, off the west coast of Africa, while another group set sail for Brazil. The idea was to compare photographs of the Hyades stars during the totality with those taken a few months earlier at night and measure any shifts in the stars’ positions relative to each other.

The idea was to compare photographs of the Hyades stars during the totality with those taken a few months earlier at night and measure any shifts in the stars’ positions relative to each other. Most of Eddington’s photographs during the eclipse turned out to be useless, because wispy clouds obscured the stars. But one good photograph allowed him to discern a tiny defection: his measurement and Einstein’s prediction were in good agreement. “Through clouds, hopeful,” he telegraphed home. The team in Brazil had better luck with weather, but its photographs could not be examined until the members returned to Europe. On November 6, the offcial results of the expeditions were presented at a joint meeting of the Royal Society and the Royal Astronomical Society in London.

Little did McCormick know that she, a Kiwi mother with no formal scientifc training, was treading on the legacy of Albert Einstein, possibly the most celebrated scientist of all time. In his general theory of relativity, completed in 1915, Einstein proposed a whole new theory of gravity. Instead of the Newtonian idea of gravity as an attractive force, he conceptualized gravity as geometry: a massive object warps the fabric of space-time around it. That means light, instead of traveling in a straight line, takes a curved path in its vicinity. Einstein’s equations predicted by just how much the light’s path would bend. The stunning confrmation came four years later. A total solar eclipse was to take place on May 29, 1919.

Pull against gravity and you are accelerating and thus slowing your clock down. So Einstein’s theory predicted that light would be bent by the presence of a large mass. It was a highly unexpected prediction of the theory, but one that could be tested: a perfect scenario for a scientific theory. Convincing evidence for this picture of a curved space-time was provided by the British astronomer Arthur Eddington’s observations of light from distant stars recorded during the solar eclipse of 1919. The theory predicted that the light from distant stars would be bent by the gravitational effect of the Sun. Eddington needed the eclipse to block out the glare of the Sun so that he could see the stars in the sky.

An aeroplane flying from London to New York takes a curved path passing over Greenland rather than the straight line we’d expect by looking at a map of the Earth. This curved line is the shortest path between the two points on the Earth. Light too found the shortest path from the star to Eddington’s telescope on Earth. Eddington announced his experimental evidence confirming Einstein’s ideas on 6 November 1919. Within days, newspaper headlines across the world trumpeted the great achievement: ‘EINSTEIN THEORY TRIUMPHS: Stars Not Where They Seemed To Be, but Nobody Need Worry’ announced the New York Times; ‘Revolution in Science’ declared the London Times. Although we’re quite used to Higgs bosons or gravitational waves hitting the headlines, this was probably the first time in history that a scientific achievement was given such public exposure.

Heralded by journalists as the new Newton, the obscure 40-year-old Einstein shot to international fame. If you are finding all this warping of space and time bending your brain, don’t despair. You are in good company. After Eddington announced his discovery that light bends, a colleague came up to congratulate him: ‘You must be one of only three people in the world to understand Einstein’s theory.’ When Eddington failed to respond, the colleague prompted: ‘Come, come, there is no need to be modest.’ ‘On the contrary,’ replied Eddington, ‘I was trying to think who was the third.’ But trying to say what happens to time as we head back towards the Big Bang would test even Eddington’s understanding of Einstein’s theory. 10 There is a place where time stands still.

That provides an easy test of the theory—except for the fact that the sun is so bright that we cannot see stars near it. But in 1919 the British astronomer Arthur Eddington came up with a clever solution, very much in the spirit of Einstein’s aphorism: by looking at the stars near the sun during a solar eclipse, Eddington realized, he could measure whether they had shifted by the amount Einstein predicted. Eddington set off to the South Pacific, made his observations, and pronounced Einstein correct. Acrimonious arguments ensued, because the difference between results that supported Einstein and results that disproved him was tiny, and Eddington was pushing the instruments available in 1919 to their very limits; yet despite the theory of relativity’s complexity,* astronomers could agree on what they needed to measure and how to measure it.

It was then just a matter of whether Eddington had got the measurements right. Coming down from the sublime movement of the stars to the brutal bombardment of Tinghai, though, we immediately see that things are much messier when we are dealing with human societies. Just what should we be measuring to assign scores to social development? If Einstein provides our theoretical lead, we might take a practical lead from the United Nations Human Development Index, not least because it has a lot in common with the kind of index that will help answer our question.

Research into radioactivity—the natural transmutation of elements—led to strong suspicions that some kind of natural nuclear process lurked behind it all, perhaps the same nuclear process that liberated sufficient energy to keep the stars shining. In 1920, with the carnage of the Great War freshly ended, the English astrophysicist Sir Arthur Eddington offered prescient reflections on the source of stellar energy at a meeting of the British Association for the Advancement of Science: A star is drawing on some vast reservoir of energy by means unknown to us. This reservoir can scarcely be other than the subatomic energy which, it is known, exists abundantly in all matter; we sometimes dream that man will one day learn how to release it and use it for his service.

Our big moon also pulls large tides, which twice a day leave large tracts of the ocean margins high and dry. Long ago, stranded fish evolved lungs. Ultimately, this drove the colonization of the land. Our big moon has even driven science. Total eclipses blot out the sun and make stars visible close to the solar disk. In 1919, this permitted the observation of the bending of starlight by the gravity of the sun, a key prediction of Einstein’s theory of gravity. Isaac Asimov, in his 1972 essay “The Tragedy of the Moon,” even claimed that had the moon belonged to Venus, rather than to the earth, science would have arisen 1,000 years earlier.

Afterwards, it was realized that violent convulsions on the solar surface, or photosphere, could fire magnetic missiles at our planet with devastating effects. In the 1920s, the British astrophysicist Sir Arthur Eddington deduced the internal structure of the sun and its central temperature of more than ten million degrees merely by assuming that it is a giant ball of gas. The key to this was his recognition that, because the sun is not noticeably expanding or contracting, every portion of its interior must be in perfect balance. In such a state of “hydrostatic equilibrium,” the force of gravity pulling inward on every chunk of solar matter must be perfectly countered by the force of the hot gas pushing outwards.

In such a state of “hydrostatic equilibrium,” the force of gravity pulling inward on every chunk of solar matter must be perfectly countered by the force of the hot gas pushing outwards. Although we now know that the sun’s heat comes from the nuclear fusion of hydrogen to helium, the by-product of which is sunlight, remarkably Eddington’s conclusions did not require him to know anything about the source of solar heat. As pointed out in Chapter 15, the sun’s central temperature depends essentially only on its mass and would be the same for a similar mass of bananas, rusty bicycles, or discarded TV sets. Eddington’s sun was a predictable and somewhat dull ball of hot gas. However, the fact that it has a magnetic field changes everything. It makes the nearest star an unpredictable, seething, explosive, infinitely surprising laboratory for extreme physics.

This analogy explains the orbits of the planets; Earth is simply rolling around in the dimple that the sun makes in the rubber sheet. Light doesn’t go in a straight line, but in a curved path around stars—an effect that the British astronomer Sir Arthur Eddington went on an expedition in 1919 to observe. Eddington measured the position of a star during a solar eclipse and spotted the curvature that Einstein had predicted (Figure 51). Einstein’s equations also predicted something much more sinister: the black hole, a star so dense that nothing can escape its grasp, not even light. Figure 51: Gravity bends light around the sun. A black hole begins, like all stars, as a big ball of hot gas—mostly hydrogen.

There were a few problems. Mercury’s orbit, for instance, wobbled in a way that disagreed with what Newton predicted, but on the whole, Newton’s theories were tested again and again, and they usually passed. Einstein’s theories corrected Newton’s errors; they explained Mercury’s wobble, for instance. These theories also made testable predictions about the way gravity works. Eddington observed the bending of starlight during a solar eclipse, confirming one of those predictions. String theory, on the other hand, ties together a number of existing theories in a very pretty way, and makes a number of predictions about the way black holes and particles behave, but none of those predictions are testable or observable.

He also realized that according to his theories light should be deflected by the sun. Einstein realized that the sun’s gravity would be powerful enough to bend the starlight of nearby stars. Since these stars could only be seen during a solar eclipse, Einstein proposed that an expedition be sent to witness the solar eclipse of 1919 to test his theory. (Astronomers would have to take two pictures of the night sky, one where the sun was absent and another during a solar eclipse. By comparing these two photographs, the position of the stars during the eclipse would have to move due to the sun’s gravity.) He was certain his theory would be shown to be correct.

He was convinced he was correct, he wrote to his colleagues, because it had superb mathematical beauty and symmetry. When this epic experiment was finally performed by astronomer Arthur Eddington, there was remarkable agreement between Einstein’s prediction and the actual result. (Today, the bending of starlight due to gravity is routinely used by astronomers. When starlight passes near a distant galaxy, light is bent, giving the appearance of a lens bending the light. These are called gravity lenses or Einstein lenses.) Einstein would go on to win the Nobel Prize in 1921. Soon, he became one of the most recognized figures on the planet, even more than most movie stars and politicians.

This concept was so bizarre that, for many decades, it was considered science fiction, a strange by-product of Einstein’s equations that didn’t exist in the real world. Astronomer Arthur Eddington once wrote that “there should be a law of Nature to prevent a star from behaving in this absurd way!” Einstein even wrote a paper arguing that, under normal conditions, black holes could never form. In 1939, he showed that a whirling ball of gas could never be compressed by gravity to within the event horizon. Ironically, that very same year, Robert Oppenheimer and his student Hartland Snyder showed that black holes could indeed form from natural processes that Einstein did not foresee.

Voltaire wrote one of the most successful, Elements of Newton’s Philosophy, much as Bertrand Russell would later write ABC of Relativity. An Italian writer produced Newtonianism for Ladies, and an English author using the pen name Tom Telescope wrote a hit children’s book. But in physics a mystique of impenetrability only adds to a theory’s allure. In 1919, when the New York Times ran a story on Einstein and relativity, a subheadline declared, “A Book for 12 Wise Men.” A smaller headline added, “No More in All the World Could Comprehend It.” A few years later a journalist asked the astronomer Arthur Eddington if it was true that only three people in the world understood general relativity. Eddington thought a moment and then replied, “I’m trying to think who the third person is.”

— THERE’S A CATCHPHRASE, the arrow of time, familiarly used by scientists and philosophers in many languages (la flèche du temps, Zeitpfeil, zamanın oku, ось времени) as shorthand for a complex fact that everyone knows: time has a direction. The phrase spread widely in the 1940s and 1950s. It came from the pen of Arthur Eddington, the British astrophysicist who first championed Einstein. In a series of lectures at the University of Edinburgh in the winter of 1927 Eddington was attempting to comprehend the great changes under way in the nature of scientific thought. The next year he published his lectures as a popular book, The Nature of the Physical World. It struck him that all previous physics was now seen to be classical physics, another new expression.

SIX * * * Arrow of Time The great thing about time is that it goes on. But this is an aspect of it which the physicist sometimes seems inclined to neglect. —Arthur Eddington (1927) WE ARE FREE to leap about in time—all this hard-won expertise must be good for something—but let’s just set the clock to 1941 again. Two young Princeton physicists make an appointment to call at the white clapboard house at 112 Mercer Street, where they are led into Professor Einstein’s study. The great man is wearing a sweater but no shirt, shoes but no socks. He listens politely as they describe a theory they are cooking up to describe particle interactions.

Historians of science have determined, for example, that in one of the most famous experiments in the history of science, the confirmation bias was hard at work. In 1919, the British astronomer Arthur Stanley Eddington tested Einstein's prediction for how much the sun would deflect light coming from a background star during an eclipse (the only time you can see stars behind the sun). It turns out that Eddington's measurement error was as great as the effect he was measuring. As Stephen Hawking (1988) described it, "The British team's measurement had been sheer luck, or a case of knowing the result they wanted to get, not an uncommon occurrence in science." In going through Eddington's original data, historians S. Collins and J.

Collins and J. Pinch (1993) found that "Eddington could only claim to have confirmed Einstein because he used Einstein's derivations in deciding what his observations really were, while Einstein's derivations only became accepted because Eddington's observation seemed to confirm them. Observation and prediction were linked in a circle of mutual confirmation rather than being independent of each other as we would expect according to the conventional idea of an experiment test." In other words, Eddington found what he was looking for. Of course, science contains a special self-correcting mechanism to get around the confirmation bias: other people will check your results or rerun the experiment.

Reprinted in the January/February 1996 issue of the Journal of Historical Review, the organ of Holocaust denial, is a famous quote from the nineteenth-century German philosopher Arthur Schopenhauer, which is quoted often by those on the margins: "All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as self-evident." But "all truth" does not pass through these stages. Lots of true ideas are accepted without ridicule or opposition, violent or otherwise. Einstein's theory of relativity was largely ignored until 1919, when experimental evidence proved him right. He was not ridiculed, and no one violently opposed his ideas.

“Time’s arrow” was already the catchphrase for this directionality, so evident to common experience, yet so invisible in the equations of physicists. There, in the equations, the road from past to future looked identical to the road from future to past. “There is no signboard to indicate that it is a one-way street,” complained Arthur Eddington. The paradox had been there all along, since Newton at least, but relativity had highlighted it. The mathematician Hermann Minkowski, by visualizing time as a fourth dimension, had begun to reduce past-future to the status of any pair of directions: left-right, up-down, back-front. The physicist drawing his diagrams obtains a God’s-eye view.

If Science Is the Modern Deity, Then the Public Is on the Verge of Deicide The epochal moment for the prestige of modern science among the public came on November 6, 1919, when the Royal Society, meeting in Piccadilly, London, announced the findings of Arthur Eddington’s expedition to the island of Principe and the city of Sobral in northern Brazil. At stake was the very shape of the universe. Eddington, head of the Cambridge Observatory, had measured the gravitational curvature of light during the solar eclipse of May 29. The Newtonian universe, with its notions of absolute space, predicted a curvature of 0.87 arc-seconds. Albert Einstein’s general theory of relativity, however, had done away with absolute space.

Because a thesis must rely on abstractions like “the public” and “authority” – or, for that matter, “gravity” and “relativity” – it is to the effects that we must look for both support and falsification. Eddington’s findings in Brazil and Principe, for example, were in line with the predictable effects of Einstein’s general theory of relativity. Identifying effects in human affairs is beyond tricky, because the instances are so few and the causes interact rather bafflingly with each other. The analyst must live with a higher degree of uncertainty and imprecision than a physical scientist would tolerate. I wish I could offer you a number, like Einstein’s curvature of light, to prove or disprove my story: but I can’t.

In general, the prestige of the scientist derived from the belief that he journeyed to realms of mystery and brought back material benefits for the human race. But certain conditions particular to the event helped amplify the resonance of Einstein’s achievement. 6.1 Albert Einstein (1947)[90] It was the first major scientific breakthrough in the age of mass media – and it occurred in a field that was impenetrable to all but a handful of brilliant specialists. When told that people believed only three scientists in the world could understand general relativity, Eddington grew quiet. “I’m just wondering who the third might be,” he explained. The public was told by the news media that the structure of the universe had been changed in incomprehensible ways by men of superhuman intellect.

Unweaving the Rainbow by Richard Dawkins

Any sufficiently advanced technology is indistinguishable from magic, Arthur Eddington, Boeing 747, complexity theory, correlation coefficient, David Attenborough, discovery of DNA, double helix, Douglas Engelbart, Douglas Engelbart, Eddington experiment, I think there is a world market for maybe five computers, Isaac Newton, Jaron Lanier, Mahatma Gandhi, music of the spheres, Necker cube, p-value, phenotype, Ralph Waldo Emerson, Richard Feynman, Ronald Reagan, Skinner box, Steven Pinker, Stuart Kauffman, world market for maybe five computers, Zipf's Law

from 'Remembering Richard Feynman', The Skeptical Inquirer (1988) Newton's dissection of the rainbow into light of different wavelengths led on to Maxwell's theory of electromagnetism and thence to Einstein's theory of special relativity. If you think the rainbow has poetic mystery, you should try relativity. Einstein himself openly made aesthetic judgements in science, and perhaps went too far. 'The most beautiful thing we can experience,' he said, 'is the mysterious. It is the source of all true art and science.' Sir Arthur Eddington, whose own scientific writings were noted for poetic flair, used the solar eclipse of 1919 to test General Relativity and returned from Principe Island to announce, in Banesh Hoffmann's phrase, that Germany was host to the greatest scientist of the age.

This is because any perpetual motion machine would violate the laws of thermodynamics. Sir Arthur Eddington wrote: If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations—then so much the worse for Maxwell's equations. If it is found to be contradicted by observation—well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation. The Nature of the Physical World (1928) Eddington is cleverly bending over backwards to make overwhelming concessions in the first part of the passage, so that his confidence in the second part has the more impact.

Nevertheless, a few decades later Einstein's general theory of relativity gave us a fundamentally different explanation of gravity, in terms of curved space and time, and thereby predicted slightly different motions again. For instance, it correctly predicted that every year the planet Mercury would drift by about one ten-thousandth of a degree away from where Newton's theory said it should be. It also implied that starlight passing close to the Sun would be deflected twice as much by gravity as Newton's theory would predict. The observation of this deflection by Arthur Eddington in 1919 is often deemed to mark the moment at which the Newtonian world-view ceased to be rationally tenable.

The observation of this deflection by Arthur Eddington in 1919 is often deemed to mark the moment at which the Newtonian world-view ceased to be rationally tenable. (Ironically, modern reappraisals of the accuracy of Eddington's experiment suggest that this may have been premature.) The experiment, which has since been repeated with great accuracy, involved measuring the positions of spots (the images of stars close to the limb of the Sun during an eclipse) on a photographic plate. As astronomical predictions became more accurate, the differences between what successive theories predicted about the appearance of the night sky diminished. Ever more powerful telescopes and measuring instruments have had to be constructed to detect the {56} differences.

Any mechanism that could be devised to provide it was all too apt to give them enough speed to cause them to escape from the Solar system altogether. Then, in the 1920s, the English astronomer Arthur Stanley Eddington (1882–1944) worked out the internal temperature of the Sun (and of stars generally). The Sun’s enormous gravitational field tends to compress its matter and pull it inward, yet the Sun is gaseous throughout and has a density only about a quarter that of the Earth. Why does it not condense to much greater densities under the inexorable inward pull of gravity? To Eddington, it seemed that the only thing that could counteract the inward pull of gravity would be the outward expansive force of internal heat.

It involves details concerning the hydrogen atom, and that information is expressed in binary numbers. It locates the Earth relative to nearby pulsars, giving the periods of the pulsars in binary numbers. Since pulsars are in a particular place only at particular times, and since their rate of rotation slows so that they will have the given rate for only a period of time, this information tells exactly where the Earth has been relative to the rest of the Galaxy at a particular time in cosmic history. There is also a small diagram of the planets of the Solar system and an indication of Pioneer 10 itself and the path it took in going through the Solar system. The most noticeable item on the plaque, though, is a diagrammatic representation of Pioneer 10 and in front of it, to scale, an unclothed man and woman (drawn by Linda Salzman Sagan, Carl’s wife).

This might seem irrelevant to the problem of getting to the stars. If light takes 4.40 years to reach Alpha Centauri, need we not merely build up our speed to where it is faster than light and thus outrace the signal and get there in less time than light does? However, as Albert Einstein (1879–1955) first pointed out in his Special Theory of Relativity in 1905, it is impossible for any object with mass to exceed the speed of light. Einstein set this limit from purely theoretical considerations and it seemed, when it was first suggested, to go against the dictates of “common sense” (and it seems so to many people even today)—but it is true just the same. The speed-of-light limit has been verified in innumerable experiments and observations, and there is no even remotely reasonable ground for doubting it where the matter and the Universe we know are involved.

Drake had found a way to transform the Sun itself into the ultimate telescope. A consequence of the Sun’s immense mass is that it acts as a star-size “gravitational lens,” bending and amplifying light that grazes its surface. This effect, first measured during a solar eclipse in 1919 by the astronomer Arthur Eddington, was one of the key pieces of evidence that validated Einstein’s theory of general relativity. Simple math and physics, judiciously applied, show that our star bends light into a narrow beam aligned with the center of the Sun and the center of any far-distant light source. As first calculated by the Stanford radio astronomer Von Eshleman in 1979, the beam comes into focus at a point beginning some 82 billion kilometers (51 billion miles) away from the Sun, nearly fourteen times farther out than the orbit of Pluto, and extends outward into infinity.

I looked down and saw the eclipse’s shadow sweeping across the ocean toward me at breathtaking speed. Then the Moon slid into place, and sunlight shining through its mountains and valleys drew a diamond ring in the sky. The Sun’s corona popped out, white and glowing and wavering. I could see the planets all stretched out along the ecliptic—Mercury, Venus, Mars, Jupiter. The whole solar system was right in front of my eyes. Orion was directly overhead. Everyone was hooting and hollering and yelling. It was pure primal joy, like that feeling right after a big football touchdown. The eclipse itself lasted something like seven minutes, but it went by in a flash.

In this two-dimensional geometry there are no parallel lines of longitude since they all meet at the poles. No one had contemplated the idea that three-dimensional space might also bend. We realise now that Gauss was working on too small a scale to observe any significant bending of space to counter the view of a Euclidean world. Arthur Eddington’s confirmation of the bending of light from stars during the solar eclipse of 1919 supported Gauss’s hunch. Gauss never went public with his ideas, perhaps because his new geometries seemed to be at variance with the task of mathematics, which was to represent physical reality. The friends he did mention his idea to, Gauss pledged to secrecy.

Also at Trinity, working alongside Hardy and Littlewood, were the two most eminent philosophers active in England: Bertrand Russell and Ludwig Wittgenstein. Both were wrestling with the same foundational problems of mathematics that had so concerned Hilbert. And Cambridge was buzzing with new breakthroughs in physics made by the likes of J. J. Thomson, who was awarded a Nobel prize for his discovery of the electron, and Arthur Eddington, who had confirmed Gauss and Einstein’s belief that space was indeed curved and non-Euclidean. The great collaboration between Hardy and Littlewood was fuelled by the timely arrival from Göttingen of a book by Landau about prime numbers. The publication in 1909 of his two-volume work Handbuch der Lehre von der Verteilung der Primzahlen (‘Handbook of the Theory of the Distribution of Prime Numbers’) proselytised the wonders of the connections between primes and the Riemann zeta function.

In fact it turned out to be necessary to wait twelve years longer, until 1919, for the confirmation of this prediction during a total eclipse observed by an English team led by the physicist Arthur Eddington from two islands in the south Atlantic Ocean. The global effect of Eddington’s team’s confirmation was phenomenal. Not only did Einstein’s prediction hit the bull’s-eye, but the world, just emerging from under the dark pall cast by the “Great War”, was thrilled that an English team had confirmed a fantastic prediction made by an “enemy” scientist (even if Einstein had renounced his German citizenship and become Swiss in order to distance himself from German militarism); indeed, many people saw Eddington’s confirmation of Einstein’s prediction as a moment of great glory for humanity as a whole.

Not only did Einstein’s prediction hit the bull’s-eye, but the world, just emerging from under the dark pall cast by the “Great War”, was thrilled that an English team had confirmed a fantastic prediction made by an “enemy” scientist (even if Einstein had renounced his German citizenship and become Swiss in order to distance himself from German militarism); indeed, many people saw Eddington’s confirmation of Einstein’s prediction as a moment of great glory for humanity as a whole. Soon Einstein would watch helplessly as he was transformed overnight into a world-famous celebrity. The Noneuclidean Merry-go-round To conclude this tour of some of the many analogies that undergird general relativity, we will give a capsule description of the key breakthrough that brought to light the appropriate branch of mathematics for Einstein’s conception of gravitation. As we have just seen, all of Einstein’s first thought experiments about how gravity and acceleration are related had to do with linear acceleration — scenarios in which a reference frame is moving in a fixed direction but with a speed that is changing.

Friedman’s article appeared in a brief period of intellectual history in which a version of Popperian falsificationism – the idea that a hypothesis acquires scientific status only if there is a possibility that it might be refuted – was in fashion. Falsificationism enjoyed its moment in (or rather out of) the sun in May 1919, when an experiment devised by Frank Dyson was conducted by fellow British astronomer Arthur Eddington on the island of Príncipe off West Africa during a total solar eclipse. Eddington established that Einstein’s theory of relativity correctly predicted the path of light and Newton’s view of gravitational fields did not.

His prediction of the solar eclipse in 585 BC was described by Isaac Asimov as ‘the birth of science’. 2 Thales also used his scientific knowledge to anticipate an especially plentiful olive harvest. He bought options on all the olive presses in Miletus, and when demand soared he rented them out at a substantial profit. According to Aristotle, Thales’ motive was not primarily pecuniary; he aimed to provide an answer to the question so often thrown at philosophers and economists: ‘If you’re so smart, why aren’t you rich?’

A Short History of Nearly Everything by Bill Bryson

Albert Einstein, Albert Michelson, Alfred Russel Wallace, All science is either physics or stamp collecting, Apollo 11, Arthur Eddington, Barry Marshall: ulcers, Brownian motion, California gold rush, Cepheid variable, clean water, Copley Medal, cosmological constant, dark matter, Dava Sobel, David Attenborough, double helix, Drosophila, Eddington experiment, Edmond Halley, Ernest Rutherford, Fellow of the Royal Society, flying shuttle, Gregor Mendel, Harvard Computers: women astronomers, Helicobacter pylori, Higgs boson, Isaac Newton, it's over 9,000, James Watt: steam engine, John Harrison: Longitude, Kevin Kelly, Kuiper Belt, Large Hadron Collider, Louis Pasteur, luminiferous ether, Magellanic Cloud, Menlo Park, Murray Gell-Mann, out of africa, Richard Feynman, Stephen Hawking, supervolcano, Thomas Malthus, Wilhelm Olbers

There was no such book, no such publisher, no such circle of learned men, but the notion stuck anyway. Soon the number of people who could grasp relativity had been reduced even further in the popular imagination—and the scientific establishment, it must be said, did little to disturb the myth. When a journalist asked the British astronomer Sir Arthur Eddington if it was true that he was one of only three people in the world who could understand Einstein's relativity theories, Eddington considered deeply for a moment and replied: “I am trying to think who the third person is.” In fact, the problem with relativity wasn't that it involved a lot of differential equations, Lorentz transformations, and other complicated mathematics (though it did—even Einstein needed help with some of it), but that it was just so thoroughly nonintuitive.

It was a question that would occupy his thoughts for most of the next decade and lead to the publication in early 1917 of a paper entitled “Cosmological Considerations on the General Theory of Relativity.” The special theory of relativity of 1905 was a profound and important piece of work, of course, but as C. P. Snow once observed, if Einstein hadn't thought of it when he did someone else would have, probably within five years; it was an idea waiting to happen. But the general theory was something else altogether. “Without it,” wrote Snow in 1979, “it is likely that we should still be waiting for the theory today.” With his pipe, genially self-effacing manner, and electrified hair, Einstein was too splendid a figure to remain permanently obscure, and in 1919, the war over, the world suddenly discovered him.

Instead, you would come back to where you began (at which point, presumably, you would rather lose heart in the exercise and give up). The reason for this is that the universe bends, in a way we can't adequately imagine, in conformance with Einstein's theory of relativity (which we will get to in due course). For the moment it is enough to know that we are not adrift in some large, ever-expanding bubble. Rather, space curves, in a way that allows it to be boundless but finite. Space cannot even properly be said to be expanding because, as the physicist and Nobel laureate Steven Weinberg notes, “solar systems and galaxies are not expanding, and space itself is not expanding.” Rather, the galaxies are rushing apart. It is all something of a challenge to intuition.

The Law of Entropy is widely acknowledged in everyday life in sayings such as “Things fall apart,” “Rust never sleeps,” “Shit happens,” “Whatever can go wrong will go wrong,” and (from the Texas lawmaker Sam Rayburn) “Any jackass can kick down a barn, but it takes a carpenter to build one.” Scientists appreciate that the Second Law is far more than an explanation of everyday nuisances. It is a foundation of our understanding of the universe and our place in it. In 1928 the physicist Arthur Eddington wrote: The law that entropy always increases . . . holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell’s equations—then so much the worse for Maxwell’s equations. If it is found to be contradicted by observation—well, these experimentalists do bungle things sometimes.

The sociologist Robert Scott notes that in the Middle Ages “the belief that an external force controlled daily life contributed to a kind of collective paranoia”: Rainstorms, thunder, lightning, wind gusts, solar or lunar eclipses, cold snaps, heat waves, dry spells, and earthquakes alike were considered signs and signals of God’s displeasure. As a result, the “hobgoblins of fear” inhabited every realm of life. The sea became a satanic realm, and forests were populated with beasts of prey, ogres, witches, demons, and very real thieves and cutthroats. . . . After dark, too, the world was filled with omens portending dangers of every sort: comets, meteors, shooting stars, lunar eclipses, the howls of wild animals.8 To the Enlightenment thinkers the escape from ignorance and superstition showed how mistaken our conventional wisdom could be, and how the methods of science—skepticism, fallibilism, open debate, and empirical testing—are a paradigm of how to achieve reliable knowledge.

It’s hard to maintain hydrostatic equilibrium in anything heavier than 200 solar masses. That might seem counterintuitive to you, that gravity should lose out as a star gets more massive. Gravity is the weakest of the fundamental forces, remember? Radiation pressure, mostly from electromagnetic radiation in the form of photons, gets too strong at high masses. One of your human scientists figured this out without the help of hands-on experiments nearly a century ago, though he was more focused on the upper limit of a star’s luminosity, or brightness, rather than mass, but the two are closely related. His name was Arthur Eddington, dubbed “Sir” even though he never fought in any battle on principle.

It features Natalia Reagan, a primatologist, anthropologist, and, apparently, butt expert. 2Saturn’s rings are the most famous in our solar system, but the other gas giants also have their own, less spectacular rings. Despite the rings’ abundance in our solar system, astronomers don’t know how common rings are around other planets, because it’s so hard to find them! There’s no reason to think our solar system is special, however, so it is likely giant exoplanets are sporting some mighty fine rings of their own. 3After observing S2 for more than twenty years, astronomers used its orbit to confirm one of Einstein’s predictions called Schwarzschild precession. GRAVITY Collaboration: R.

An Israeli physicist named Mordehai Milgrom conceived the idea in 1983, when he called for a theory of modified Newtonian dynamics, or MOND. MOND advocates believe that Newtonian gravity works only in high-acceleration environments, like Earth and your solar system. Low-acceleration environments like the outer edges of galaxies operate under different gravitational rules. As much as I respect the desire to continuously prove Einstein wrong, MOND doesn’t hold up against observations of galaxies without dark matter. If it’s just a matter of gravity behaving differently at larger scales, then its effects should be observed everywhere. Your astronomers have found a couple of galaxies confirmed to be abnormally devoid of dark matter.

Like Wells, he was a man who peered constantly into the future and relayed his visions of what the world looked like. But unlike Wells, he did so as a professional scientist with a loud political voice. In the business of explaining science, Haldane had peers: the physicist James Jeans wrote popular books on cosmology, and the astronomer Arthur Eddington lectured on relativity and its bearing on religious faith. But no one ventured to tie together the ongoing developments in both science and politics the way Haldane did. No one laid out quite as clearly or prolifically how science could solve the immediate problems that people faced. The letters poured in—hundreds a week, his secretary reckoned.

The stringency of statistics delighted Haldane. Everyone should know more mathematics, he always thought. Numbers were so satisfyingly precise, equations so universal. How well they ministered to the scientific method! Had Haldane done just this and little else, he would have been an important scientist—not as revolutionary as Einstein, perhaps, and not associated for perpetuity like Watson and Crick with a single, shining discovery, but certainly among the few who altered their field beyond recognition, pushing it forward paper by paper. This is how science progresses most of the time, after all: through the accretive power of daily work, through meat-and-potatoes research.

It also returns in a new way to Davy’s early Cornish beliefs about starlight as the source of all energy in the universe: Nothing is lost; the ethereal fire, Which from the farthest star descends, Through the immensity of space Its course by worlds attracted bends, To reach the earth; the eternal laws Preserve one glorious wise design; Order amidst confusion flows And all the system is divine. If matter cannot be destroyed, Then living mind can never die; If e’en creative when alloy’d, How sure is immortality!70 Intriguingly, the first stanza appears to anticipate Einstein’s General Theory of Relativity (1915), in which light is ‘bent’ by gravity; and then Eddington’s observations of a solar eclipse in 1919, when he recorded starlight actually being bent by the sun. But apparent anticipations of this kind can be deceptive in science, often hiding a more significant contemporary meaning. Here Davy was really expressing a more traditional belief: the sudden confidence that ‘eternal laws’ govern the universe in a benign and ordered way.

(The John Dolland achromatic telescope, which corrected some prismatic distortion, was only invented in 1758, and did not come into general use-as improved by his son Peter Dolland-until the turn of the century.65) The newly appointed Astronomer Royal, Nevil Maskelyne, based at the Greenwich Observatory, was largely concerned at this time with observing lunar eclipses, planetary transits and passing comets. His special interests lay in establishing tables for use at sea as a mariner’s almanac, and in the calculation of longitude. He noted that since his seventeenth-century predecessor at Greenwich, John Flamsteed, had thoroughly mapped the heavens, he himself kept only thirty-one stars under regular observation.66 Since his long nights of riding over the moors, Herschel’s interests had roamed far beyond the safe family of the solar system, with its restricted circuit of sun, moon and six known planets.

Virtual eternity, gateways to Nowhen, the unreality of time … Do any of these lotus-eater ideas really hit us where we live, in the lifeworld? Probably not. Like Einstein himself, we are stubbornly in thrall to our temporal illusions. We cannot help feeling ourselves to be slaves to one part of the timescape (the past) and hostages to another part (the future). Nor can we help feeling that we are quite literally running out of time. Arthur Eddington, one of the first physicists to grasp Einstein’s relativity theory, declared that our intuitive sense of time’s passage is so powerful that it must correspond to something in the objective world.

Constitution contained a loophole that would allow a dictatorship to come into existence.1 Around the same time that Gödel was studying the Constitution, he was also taking a close look at Einstein’s relativity theory. The key principle of relativity is that the laws of physics should be the same for all observers. When Einstein first formulated the principle in his revolutionary 1905 paper, he restricted “all observers” to those who were moving uniformly relative to one another—that is, in a straight line and at a constant speed. But he soon realized that this restriction was arbitrary. If the laws of physics were to provide a truly objective description of nature, they ought to be valid for observers moving in any way relative to one another—spinning, accelerating, spiraling, whatever.

But to really arrive at accurate beliefs requires evidence-fuel, and the further you want to go, the more fuel you need. * 24 Einstein’s Arrogance In 1919, Sir Arthur Eddington led expeditions to Brazil and to the island of Principe, aiming to observe solar eclipses and thereby test an experimental prediction of Einstein’s novel theory of General Relativity. A journalist asked Einstein what he would do if Eddington’s observations failed to match his theory. Einstein famously replied: “Then I would feel sorry for the good Lord. The theory is correct.” It seems like a rather foolhardy statement, defying the trope of Traditional Rationality that experiment above all is sovereign. Einstein seems possessed of an arrogance so great that he would refuse to bend his neck and submit to Nature’s answer, as scientists must do.

So from a probability-theoretic standpoint, Einstein was still data-driven—he just used the data he already had, more effectively. Compared to any alternate Earths that demanded huge quantities of additional data from astronomical observations and clocks on airplanes to hit them over the head with General Relativity. There are numerous lessons we can derive from this. I use Einstein as my example, even though it’s cliché, because Einstein was also unusual in that he openly admitted to knowing things that Science hadn’t confirmed. Asked what he would have done if Eddington’s solar eclipse observation had failed to confirm General Relativity, Einstein replied: “Then I would feel sorry for the good Lord.

Popper was profoundly impressed by the differences between the allegedly “scientific” theories of Freud and Adler and the revolution effected by Einstein’s theory of relativity in physics in the first two decades of this century. The main difference between them, as Popper saw it, was that while Einstein’s theory was highly “risky,” in the sense that it was possible to deduce consequences from it which were, in the light of the then dominant Newtonian physics, highly improbable (e.g., that light is deflected towards solid bodies—confirmed by Eddington’s experiments in 1919), and which would, if they turned out to be false, falsify the whole theory, nothing could, even in principle, falsify psychoanalytic theories.

It explained mysterious anomalies in the orbit of Mercury—that confirmed prediction was the one which left Einstein feeling something had snapped in him. The general theory also predicted that starlight would be deflected, when it passed a massive body like the sun, through an angle equal to twice the value Newtonian theory predicts. The Great War delayed measurement of the Einstein value. A total eclipse of the sun (which would block the sun’s glare and make the stars beyond it visible) due on May 29, 1919, offered the first postwar occasion. The British, not the Germans, followed through. Cambridge astronomer Arthur Stanley Eddington led an expedition to Principe Island, off the West African coast; the Greenwich Observatory sent another expedition to Sobral, inland from the coast of northern Brazil.

He had been nominated for the Nobel Prize in all but two years since 1910, the secondings increasing in number after 1917; Max Planck, who was not given to exaggeration, wrote the Nobel Committee in 1919 that Einstein “made the first step beyond Newton.”610, 611 The award might have come sooner than in 1922 (belatedly for 1921: the 1922 prize was Bohr’s) had relativity been less paradoxical a revelation. Physically Einstein was not yet the amused, grandfatherly notable of his later American years. His mustache was still dark and his thick black hair had only begun to gray. C. P. Snow would observe “a massive body, very heavily muscled.”612 The Swabian-born physicist’s friends thought his loud laugh boyish; his enemies thought it rude.

When Einstein redid the standard orbital calculations with his new equations, he derived the observed perihelion precession precisely, a result he found so thrilling that it gave him heart palpitations.3 Einstein also applied general relativity to the question of how sharply the path of light emitted by a distant star would be bent by spacetime’s curvature as it passed by the sun on its way to earth. In 1919, two teams of astronomers—one camped out on the island of Principe off the west coast of Africa, the other in Brazil— tested this prediction during a solar eclipse by comparing observations of starlight that just grazed the sun’s surface (these are the light rays most affected by the sun’s presence, and only during an eclipse are they visible) with photographs taken when the earth’s orbit had placed it between these same stars and the sun, virtually eliminating the sun’s gravitational impact on the starlight’s trajectory.

As described more fully in note 2 of Chapter 6, this is an overstatement because there are examples, involving relatively esoteric particles (such as K-mesons and B-mesons), which show that the so-called weak nuclear force does not treat past and future fully symmetrically.

If correct, this would mean that there is another independent direction in which things can move, and therefore that we need to give four pieces of information to specify a precise location in space, and a total of five pieces of information if we also specify a time. Okay; that’s what the paper Einstein received in April 1919 proposed. The question is, Why didn’t Einstein throw it away? We don’t see another space dimension—we never find ourselves wandering aimlessly because a street, a cross street, and a floor number are somehow insufficient to specify an address—so why contemplate such a bizarre idea? Well, here’s why. Kaluza realized that the equations of Einstein’s general theory of relativity could fairly easily be extended mathematically to a universe that had one more space dimension.

When Frank was only thirteen, and clearly set on following in his brother’s footsteps, Robert wrote: “I don’t think you would enjoy reading about relativity very much until you have studied a little geometry, a little mechanics, a little electrodynamics. But if you want to try, Eddington’s book is the best to start on. . . . And now a final word of advice: try to understand really, to your own satisfaction, thoroughly and honestly, the few things in which you are most interested; because it is only when you have learnt to do that, when you realize how hard and how very satisfying it is, that you will appreciate fully the more spectacular things like relativity and mechanistic biology. If you think I’m wrong please don’t hesitate to tell me so.

They began their paper by asking what would happen to a massive star that has begun to burn itself out, having exhausted its fuel. Their calculations suggested that instead of collapsing into a white dwarf star, a star with a core beyond a certain mass—now believed to be two to three solar masses—would continue to contract indefinitely under the force of its own gravity. Relying on Einstein’s theory of general relativity, they argued that such a star would be crushed with such “singularity” that not even light waves would be able to escape the pull of its all-encompassing gravity. Seen from afar, such a star would literally disappear, closing itself off from the rest of the universe.

“No one could have been more ingenious,” Oppenheimer wrote, “in thinking up unexpected and clever examples; but it turned out that the inconsistencies were not there; and often their resolution could be found in earlier work of Einstein himself.” What distressed Einstein about quantum theory was the notion of indeterminacy. And yet it had been his own work on relativity that had inspired some of Bohr’s insights. Oppenheimer saw this as highly ironic: “He fought with Bohr in a noble and furious way, and he fought with the theory which he had fathered but which he hated. It was not the first time that this had happened in science.” These disputes did not prevent Oppenheimer from enjoying Einstein’s company. One evening early in 1948, he entertained David Lilienthal and Einstein at Olden Manor. Lilienthal sat next to Einstein and “watched him as he listened (gravely and intently, and at times with a chuckle and wrinkles about his eyes) to Robert Oppenheimer describing neutrinos as ‘those creatures,’ and the beauties of physics.”
