The accuracy of the measurement, however, meant that Aristarchus was out by a factor of 20 in the relative distance. He’d estimated the angle to be 87 degrees, while the true value is 89.853, almost a right angle. Small differences in angles of this size result in quite large differences in the relative size of the lengths of the sides of the triangle. It would need the invention of the telescope and some more clever mathematics to truly determine the size of the solar system. The right-angled triangle made by the Earth, Moon and Sun when the Moon is half full. Even without the invention of the telescope, astronomers could see that the Moon and Sun weren’t the only bodies processing through the sky. Ancient cultures picked up several tiny pricks of light in the night sky that behaved very differently from the plethora of other stars. They were wandering beacons of light: Mercury, Venus, Mars, Jupiter and Saturn – luminous bodies that can’t be marked on my cut-out sphere because the next night they will be located at a different point.

Although we don’t have a ship in which we can sail to the edges of the universe, scientists in the seventeenth century did come up with a cunning way to explore space: the telescope. HOW FAR CAN YOU SEE? It was Galileo’s generation that discovered you could enhance how far you can see by placing carved glass lenses in a tube. Indeed, for years Galileo himself seemed to get the credit for the invention of the telescope, but that accolade should go to the Dutch spectacle-maker Hans Lippershey, who filed a patent for an instrument ‘for seeing things far away as if they were nearby’. The Dutch instrument was able to magnify things by a factor of 3. Galileo heard about the instrument on a trip to Venice. That same night he figured out the principle on which it worked and was soon constructing instruments that could achieve a magnification of 33 times.

THE STARS IN OUR NEIGHBOURHOOD Looking at the celestial sphere on my desk, I find it laughable that the ancient Greeks thought the stars were painted on a huge celestial ball enclosing the universe with the void beyond. But they didn’t have much to go on. Given the distance of the stars from the Earth, to the naked eye they all look to be a long way away. It was impossible for the ancient astronomers to detect any depth. But the invention of the telescope brought those stars a little closer, close enough that modern astronomers could see that they were not all the same distance from the Earth. If one star is nearer to us than another, then there is a way to tell that it’s closer. Although we are stuck on the surface of the Earth, at least the Earth is moving relative to the stars, which means we get different viewpoints on the cosmos.

The chapter goes on to reappraise what Thomas Kuhn called the Copernican revolution. As we will see, the Copernican revolution was delayed until the seventeenth century: very few sixteenth-century astronomers accepted Copernicus’s claim that the Earth revolves around the sun instead of standing still at the centre of the cosmos. The real revolution in astronomy came with Tycho Brahe’s nova, with the abandonment of belief in the crystalline spheres, and with the invention of the telescope. The key date is not 1543 but 1611. The title page of Johannes Stradanus’s New Discoveries (Nova reperta, c.1591) summarizes the knowledge that marks off the modern world from the ancient. Pride of place is given to the discovery of America and the invention of the compass, with, between them, the printing press. Also present are gunpowder, the clock, silk weaving, distillation and the saddle with stirrups. 3 Inventing Discovery Discovery is what science is all about – N.

But Gilbert understood that, seen from the moon, the Earth would shine like a vast moon; and that, seen from further away, it would shine like a star (here, he directly argued against Benedetti). The moon, he thought, had continents and oceans, just like the Earth. Like Bruno, he thought the oceans would be brighter than the land. He saw no reason why the other planets should not be just like the Earth.94 Gilbert drew, before the invention of the telescope, the first map of the moon, and as a result discovered its libration, the fact that it appears to turn slightly, up and down and from side to side, as it faces the Earth. This confirmed his conviction that the planets float freely in space. Moreover, Gilbert was the first to break completely with the notion that movement in the heavens must be circular: his planets trace complicated paths through the void; such a path could explain why the moon appears to wobble in the sky.

Only where weight was concerned was man not the measure. Man ceased to be the measure of all else only with the adoption of the metric system in France in 1799.46 The basic unit of measurement (from which volumes and weights were derived) became the metre, originally defined as one ten millionth of the distance from the equator to the North Pole. The metric system merely completed a process that had begun with the invention of the telescope, which definitively destroyed the idea that the universe was made on the same scale as man. § 5 According to orthodox Christian thinking (at least until Pascal), the universe had been made to provide a home for humankind. The sun was there to provide light and heat by day, the moon and stars light by night. There was a perfect correspondence between the macrocosm (the universe as a whole) and the microcosm (the little world of the human body).

When I saw that she took my words to heart, I would rather have bitten my own finger than to give her further offense.” But Kepler remained preoccupied with his work. He envisioned Tycho’s domain as a refuge from the evils of the time, as the place where his Cosmic Mystery would be confirmed. He aspired to become a colleague of the great Tycho Brahe, who for thirty-five years had devoted himself, before the invention of the telescope, to the measurement of a clockwork universe, ordered and precise. Kepler’s expectations were to be unfulfilled. Tycho himself was a flamboyant figure, festooned with a golden nose, the original having been lost in a student duel fought over who was the superior mathematician. Around him was a raucous entourage of assistants, sycophants, distant relatives and assorted hangers-on. Their endless revelry, their innuendoes and intrigues, their cruel mockery of the pious and scholarly country bumpkin depressed and saddened Kepler: “Tycho … is superlatively rich but knows not how to make use of it.

In the Somnium he tried to make the rotation of the Earth plausible, dramatic, comprehensible: “As long as the multitude does not err,… I want to be on the side of the many. Therefore, I take great pains to explain to as many people as possible.” (On another occasion he wrote in a letter, “Do not sentence me completely to the treadmill of mathematical calculations—leave me time for philosophical speculations, my sole delight.”*) With the invention of the telescope, what Kepler called “lunar geography” was becoming possible. In the Somnium, he described the Moon as filled with mountains and valleys and as “porous, as though dug through with hollows and continuous caves,” a reference to the lunar craters Galileo had recently discovered with the first astronomical telescope. He also imagined that the Moon had its inhabitants, well adapted to the inclemencies of the local environment.

Against the view that such great construction projects were unlikely, Kepler offered as counterexamples the pyramids of Egypt and the Great Wall of China, which can, in fact, be seen today from Earth orbit. The idea that geometrical order reveals an underlying intelligence was central to Kepler’s life. His argument on the lunar craters is a clear foreshadowing of the Martian canal controversy (Chapter 5). It is striking that the observational search for extraterrestrial life began in the same generation as the invention of the telescope, and with the greatest theoretician of the age. Parts of the Somnium were clearly autobiographical. The hero, for example, visits Tycho Brahe. He has parents who sell drugs. His mother consorts with spirits and daemons, one of whom eventually provides the means to travel to the moon. The Somnium makes clear to us, although it did not to all of Kepler’s contemporaries, that “in a dream one must be allowed the liberty of imagining occasionally that which never existed in the world of sense perception.”

Strange New Worlds: The Search for Alien Planets and Life Beyond Our Solar System by Ray Jayawardhana

Albert Einstein, Albert Michelson, Arthur Eddington, cosmic abundance, dark matter, Donald Davies, Edmond Halley, invention of the telescope, Isaac Newton, Johannes Kepler, Kuiper Belt, Louis Pasteur, Pierre-Simon Laplace, planetary scale, Pluto: dwarf planet, Search for Extraterrestrial Intelligence, Solar eclipse in 1919

There was little discussion of extraterrestrial life, with a few exceptions. The tide started to turn with the publication of Nicolas Copernicus’s infuential volume On the Revolutions of Celestial Bodies just before his death in 1543. He posited that the Sun occupied the center of the universe, thus displacing the Earth from its unique niche. But the true revolution occurred with the invention of the telescope at the beginning of the next century. Galileo’s 1610 discovery of four moons circling Jupiter proved the existence of heavenly bodies that did not orbit the Earth. He also showed that Venus exhibited a full set of phases, just like the Moon, as predicted by Copernicus’s Sun-centered model. Perhaps even more dramatic was the revelation from Galileo’s telescopic observations that the Moon was quite similar to the Earth in many ways.

These celestial alignments follow a precise cycle, with time intervals of 8.0, 121.5, 8.0, and 105.5 years in the case of Venus; Mercury transits are more frequent, with about a dozen or so per century. As Venus passes in front of the Sun, taking several hours to do so, it appears as a black dot about one-thirtieth the solar diameter. It’s big enough to be seen with the (properly protected) naked eye, but there are no records of a transit being observed before the invention of the telescope early in the seventeenth century. That’s not too surprising given the rarity of the event. In 1629 Johannes Kepler, as he investigated the laws of planetary motion, realized that transits of both Venus and Mercury would occur two years later. Unfortunately, he didn’t live to see either, and the Venus transit of 1631 was not visible from Europe in any case. But European astronomers were able to observe the transit of Mercury in November that year, vindicating Kepler’s prediction.

Yet Venus, with a broiling surface temperature of 400 degrees Celsius, a crushing surface pressure ninety times that of the Earth’s at sea level, and a carbon dioxide atmosphere that confrms our worst fears of the greenhouse effect, cannot sustain life as we know it. That’s why fnding, or even imaging, Earth-size planets elsewhere is one thing, but detecting life is quite another. Chapter 9 Signs of Life How Will We Find E.T.? Once the invention of the telescope showed that the Earth is but one world among many, it opened the serious prospect of life on other planets. The reconnaissance within our solar system has revealed some tantalizing hints but no defnitive evidence so far. Now that we are on the verge of fnding extrasolar worlds with conditions hospitable for life, the question has gained a new urgency. Guided by remote observations of the Earth, clues about how the solar system’s three large rocky planets have evolved, and theoretical models of planets in other stellar environments, scientists are fguring out how best to search for extraterrestrial life.

The idea that planetary orbits were not perfectly circular was a huge leap forward in planetary theory and in understanding the motions of Mars. Hail, children of Mars! Mars has been a key player in astronomy for millennia, due in large part to its proximity to Earth. While the more distant outer planets – Uranus, Neptune, the now-demoted Pluto – were only discovered following the invention of the telescope in the 1600s, the inner and nearby outer planets have always been visible with the naked eye, and so have been included as part of our Solar System models since the year dot. The invention of the telescope enabled us to characterise our nearest neighbours better than ever before. Many astronomers turned their eyes Mars-ward; Galileo Galilei, widely regarded as one of the fathers of the telescope, is thought to have observed the planet from 1608 to 1610, completing some of the very first telescopic views of Mars.

It was not for nearly 1,300 years, however, that a major writer dealt with the Moon again. This came in 1532 in Orlando Furioso, an epic poem written by the Italian poet Ludovico Ariosto (1474–1533). In it, one of the characters travels to the Moon in the divine chariot that carried the prophet Elijah in a whirlwind to Heaven. He finds the Moon well populated by civilized people. The notion of a plurality of worlds received still another push forward with the invention of the telescope. In 1609, the Italian scientist Galileo Galilei (1564–1642) constructed a telescope and pointed it at the Moon. For the first time in history, the Moon was seen magnified, and more clearly detailed than was possible with the unaided eye. Galileo saw mountain ranges on the Moon, together with what looked like volcanic craters. He saw dark, smooth patches that looked like seas. Quite plainly and simply, he was seeing another world.

Even more important was what happened when he looked through his telescope at the Milky Way. The Milky Way is a faint, luminous fog that seems to form a belt around the sky. In some ancient myths, it was pictured as a bridge connecting heaven and Earth. To the Greeks it was sometimes seen as a spray of milk from the divine breast of the goddess Hera. A more materialistic way of looking at the Milky Way, prior to the invention of the telescope, was to suppose it was a belt of unformed star matter. When Galileo looked at the Milky Way, however, he saw it was made up of myriads of very faint stars. For the first time, a true notion of how numerous the stars actually were broke in on the consciousness of human beings. If God had granted Abraham telescopic vision, the assurance of innumerable descendants would have been formidable indeed.

The low temperatures provide an advantage, though, because once molecules are synthesized on Titan, they tend to stick around: The higher the temperature, the faster molecules fall to pieces. On Titan the molecules that have been raining down like manna from heaven for the last 4 billion years might still be there, largely unaltered, deep-frozen, awaiting the chemists from Earth. THE INVENTION OF THE TELESCOPE In the seventeenth century led to the discovery of many new worlds. In 1610 Galileo first spied the four large satellites of Jupiter. It looked like a miniature solar system, the little moons racing around Jupiter as the planets were thought by Copernicus to orbit the Sun. It was another blow to the geocentrists. Forty-five years later, the celebrated Dutch physicist Christianus Huygens discovered a moon moving about the planet Saturn and named it Titan. † It was a dot of light a billion miles away, gleaming in reflected sunlight.

Still others suggested that the dense cloud of fine particles accompanying the fragments of Comet Shoemaker-Levy 9 into Jupiter would disrupt the magnetosphere of Jupiter or form a new ring. A comet this size should impact Jupiter, it is calculated, only once every thousand years. It's the astronomical event not of one lifetime, but of a dozen. Nothing on this scale has occurred since the invention of the telescope. So in mid July 1994, in a beautifully coordinated international scientific effort, telescopes all over the Earth and in space turned towards Jupiter. Astronomers had over a year to prepare. The trajectories of the fragments in their orbits around Jupiter were estimated. It was discovered that they would all hit Jupiter. Predictions of the timing were refined. Disappointingly, the calculations revealed that all impacts would occur on the night side of Jupiter, the side invisible from the Earth (although accessible to the Galileo and Voyager spacecraft in the outer Solar System).

The turning point in the scientific rejection of a human-centered universe was the Copernican model of the solar system, in which the earth no longer held a central position. Ironically, Copernicus’s own worldview was anthropomorphic, even to the extent that he comforts us by pointing out that, despite his heliocentric model, the earth is almost at the universe’s center: “Although [the earth] is not at the center of the world, nevertheless the distance [to that center] is as nothing in particular when compared to that of the fixed stars.” With the invention of the telescope, observations in the seventeenth century, such as the fact that ours is not the only planet orbited by a moon, lent weight to the principle that we hold no privileged position in the universe. In the ensuing centuries the more we discovered about the universe, the more it seemed ours was probably just a garden-variety planet. But the discovery relatively recently of the extreme fine-tuning of so many of the laws of nature could lead at least some of us some back to the old idea that this grand design is the work of some grand designer.

Day We Found the Universe by Marcia Bartusiak

From the days of Ptolemy, astronomers talked about certain stars in the sky that appeared “cloudy” to the eye. The most famous is in the northern constellation Andromeda, the mythical princess situated in the sky near her parents, Cassiopeia and Cepheus, and her husband, Perseus. At her waist is an oval patch of light, best seen on the darkest of nights. As early as the tenth century, astronomer Al-Sufi of Persia noted it as a “little cloud” in his catalog of the heavens. With the invention of the telescope more nebulae were sighted, and by the early 1700s Edmond Halley (of comet fame) counted six in all. To some observers, these pale entities were breaks in the celestial sphere, through which the light of the Empyrean—the highest heaven—came shining down. Others suggested that they were the hazy atmospheres surrounding distant stars. Halley, however, thought of them as unique celestial objects, unlike anything else in the heavens.

They instead turned up at the Lowell Observatory, Lick Observatory's long-standing competitor located in northern Arizona. My Regards to the Squashes Roman god. Bringer of War. Fourth planet from the Sun. Astronomers eager to solve the spiral nebulae dilemma had Mars, strangely enough, to thank for a further step toward an answer—at least in a roundabout way. The red planet, with its vivid ruby luster, has fascinated stargazers for millennia, but interest grew even more intense after the invention of the telescope. With the extra magnification astronomers could at last discern markings on the surface of Mars. Bright patches around its poles, similar in appearance to our own planet's arctic and antarctic regions, were seen to wax and wane with the Martian seasons. So Earthlike was this behavior that by 1784 William Herschel was reporting that Mars “is not without a considerable atmosphere … so that its inhabitants probably enjoy a situation in many respects similar to ours.”

Although born to a poor family under adverse circumstances, Kepler was lucky enough to acquire very precise secondary data, carefully amassed for several decades, on the motions of objects in the celestial sphere. With his luck and superior mathematical talent, Kepler solved the mystery of the planets. Kepler’s data was primarly gathered by Tycho Brahe (1546–1601), a Danish nobleman and brilliant astronomer who made the most accurate astronomical observations of his time by devising the most precise instruments available prior to the invention of the telescope. With generous royal support from the king of Denmark, Brahe built a research center called Uraniborg (castle of the heavens), which became the finest observatory in Europe. He designed and built new instruments, calibrated them, and instituted scrupulous nightly observations for over twenty years. In 1600 Brahe invited Kepler—a bright but underprivileged teacher—to become his assistant.

His identification meant that, for the first time in history, astronomers knew exactly which star had blown up: in other words, they had “before and after” photographs of the exploding star, which would allow them to trace the final stages of a massive star’s evolution better than ever before. By midmorning of February 24, scientists around the world learned about the discovery, tipped off by phone calls from giddy colleagues and a telegram from the International Astronomical Union. Their delight had to do with the fact that Supernova 1987A (as it came to be known) was the first one observed in our galactic neighborhood since the invention of the telescope nearly four centuries earlier. It was the nearest and the brightest supernova seen in 383 years—since Johannes Kepler observed a supernova in our own galaxy with his naked eye in 1604—and as such, it offered astronomers an unprecedented opportunity to witness a massive star’s last hurrah. Over the next hours and days, the star’s debris would expand outward from the site of the initial explosion, colliding with dust and gas in the space around it.

We know that in fact the Sun sits on an outer arm of an average spiral galaxy in a nondescript part of the Universe. We know, with the benefit of centuries of ever more comprehensive and accurate astronomical data, leading to our current understanding in modern cosmology, that the Universe has no center at all, and may indeed extend out in all directions forever. But of course poor Copernicus, working before the invention of the telescope, could not have known any of this. It would take a relatively unknown astronomer in the sleepy English market town of Wallingford near Oxford to make the next big leap forward. His name was Thomas Digges and he was born in 1546, a few years after Copernicus died. His father, Leonard Digges, was also a scientist—credited with the invention of the theodolite, an instrument used (these days mainly by surveyors) to measure vertical and horizontal angles very precisely.

In 1616, On the Revolutions was listed on the Index of Prohibited Books, where it remained for more than two hundred years. The philosophical conflict and change in perception that his ideas engendered are sometimes referred to as the Copernican Revolution. HOROSCOPE FOR NICOLAUS COPERNICUS Astronomers and astrologers in Copernicus’s time shared the same pool of information about the positions of the heavenly bodies against the backdrop of the stars. Until the invention of the telescope in the seventeenth century, position finding and position predicting constituted the entirety of planetary science—and the basis for casting horoscopes. He was christened for his father—Mikolaj in Polish, Niklas in German, his native tongue. Later, as a scholar, he Latinized his name, but he grew up Niklas Koppernigk, the second son and youngest child of a merchant family from the copper-mining regions of Silesia.

It’s not that opinions and observations are bad. They can be a helpful starting point for inquiry. But there is a more complete approach—a scientific approach. Science finishes the job by putting opinions and observations to the test wherever possible. Individual fields of science have had periods of extraordinary development, often spurred by new technologies. Astronomy was energized by the invention of the telescope, as biology was by the microscope. The last quarter century has seen the emergence of a new field—cognitive neuroscience—fueled by techniques for measuring the activity of a brain while it works. Techniques such as functional magnetic resonance imaging (fMRI) and high-density electroencephalography (EEG) have enabled us to explore the brain in ways that elucidate how we perceive, remember, think, feel—and have insights.

Most recently, the genomics revolution that began more than fifty years ago with the discovery of DNA has long promised more in the way of medical treatments than it has been able to deliver; yet that hasn’t stopped us from devoting enormous resources to the pursuit of science.26 Why should the science required to understand social problems such as urban poverty or economic development or public education deserve less attention? It should not. Nor can we claim anymore that the necessary instruments don’t exist. Rather, just as the invention of the telescope revolutionized the study of the heavens, so too by rendering the unmeasurable measurable, the technological revolution in mobile, Web, and Internet communications has the potential to revolutionize our understanding of ourselves and how we interact. Merton was right: Social science has still not found its Kepler. But three hundred years after Alexander Pope argued that the proper study of mankind should lie not in the heavens but in ourselves, we have finally found our telescope.27 Let the revolution begin.… ACKNOWLEDGMENTS This book has been in the writing for more than three years, and on my mind for twice as long as that.

Now, thanks to the abundance of plates and Miss Leavitt’s completion of the North Polar Sequence, Miss Vann had the necessary tools to assess the novae’s changing magnitudes over time and create a light curve for each one. On June 8, 1918, shortly before she left the observatory to take up war work, a new nova erupted in the constellation Aquila, outshining all but the very brightest stars for several weeks. At magnitude −0.5, Nova Aquilae 1918 proved the brightest such sight since the invention of the telescope, but its photographic study fell to the second Pickering Fellow, Dorothy W. Block, a 1915 graduate of Hunter College in New York City. Unlike the astronomical fellowship of the Nantucket Maria Mitchell Association, now permanently assigned to Margaret Harwood, the Pickering Fellowship entailed no Nantucket residency rule. The recipient was welcome to visit Miss Harwood on the island during the summer months, if she so chose, but the real reward consisted of research funding at Harvard through a typical fall-to-spring academic year.

I’ve got one more intersection for you—and this one isn’t about presidents. In my professional community of astrophysicists, about 90 percent of us, plus or minus, are liberal, antiwar Democrats. Yet practically all of our detection hardware flows out of historical relationships with military hardware. And that connection goes back centuries. In the early 1600s Galileo heard about the invention of the telescope in the Netherlands—which they used for looking in people’s windows—and he built one himself. Almost no one had thought to look up with the telescope, but Galileo did, and there he found the rings of Saturn, the phases of Venus, sunspots. Then he realized, Hey, this would be good for our defense system. So he demonstrated his instrument to the doges of Venice, and they ordered a supply of telescopes right then and there.

, visibility (‘repeat please’), and transmission speed (‘not so fast!’).”6 Telecommunications systems have appeared, disappeared, and reappeared across the centuries: fire beacons, heliographs, and primitive forms of semaphore based on hanging or waving anything from flags to lanterns in the air. When the Spanish armada entered the English Channel in July 1588, a network of fire beacons raised the alarm, cradling the newborn Thomas Hobbes with fear. The invention of the telescope in the early seventeenth century extended the distance between relay stations and allowed more complex symbols to be distinguished. The feasibility of a “method of discoursing at a Distance, not by Sound, but by Sight” was addressed by Robert Hooke in a lecture, “Shewing a Way how to communicate one’s Mind at great Distances,” delivered to the Royal Society on 21 May 1684. Having advanced the optical instruments of his day, Hooke showed that “‘tis possible to convey Intelligence from any one high and eminent Place, to any other that lies in Sight of it, tho’ 30 or 40 Miles distant, in as short a Time almost, as a Man can write what he would have sent, and as suddenly to receive an Answer as he that receives it hath a Mind to return it. . . .

Kepler suspected the data might be wrong, but he didn’t insist on the correctness of his theory (which was wise, in retrospect, since the theory had no chance of success; as we now know, there are more than six planets). Nevertheless, he didn’t give up. He continued to ponder the planets and soon got a break when Tycho Brahe asked him to be his assistant. Tycho (as historians always call him) was the world’s best observational astronomer. His data were ten times more accurate than any obtained previously. In the days before the invention of the telescope, he’d devised special instruments that allowed him, with the naked eye, to resolve the angular positions of the planets to within two arcminutes. That’s one-thirtieth of a degree. To get a sense of what a tiny angle this is, imagine looking up at the full moon on a clear night while holding your little finger all the way out in front of your face. Your little finger turns out to be about sixty arcminutes wide, and the moon is about half that.

In fact, while he improved on Ptolemy’s cosmology by removing the earth from the centre of the universe and replacing it with the sun, we now know that even this was not quite right. To Copernicus, the outer sphere of the fixed and distant stars was also centred on the sun. But we have learnt that our sun sits on an outer arm of an average spiral galaxy in a nondescript part of the universe, and certainly not at the universe’s centre. How could poor Copernicus know this before the invention of the telescope? Indeed, modern cosmology based on Einstein’s theory and centuries of ever more comprehensive and accurate astronomical data have convinced us that the universe has no centre at all, much as the surface of the earth has no centre. What Copernicus described correctly (apart from the elliptical orbits that had to await the work of Kepler) was only our sun-centred solar system. So despite his undoubted genius, I stand by my belief that Copernicus was the last astronomer of the Marāgha School.

He had served his father well, and he was tired of war. In his court of architects and painters, calligraphers and poets, Mongol vigour and Persian delicacy struck momentary fire. Another son, the talented prince Baisanghur, assembled a forty-strong workshop of illuminators and book-binders–and a unique library–before drinking himself to death at the age of thirty-seven. In Samarkand, meanwhile, two centuries before the invention of the telescope, Ulug Beg was charting the course coordinates of 1,018 stars, and recalculating the stellar year to within seconds of that computed by electronics. At the heart of this renaissance was Shah Rukh’s prodigious queen, Gawhar Shad. These were her children. Her foundations–mosques, palaces, colleges, baths, libraries–spread in lavish patronage all over eastern Persia and Afghanistan. In 1405, with the rare tolerance of a Sunni for a Shia saint, she founded a famous mosque in Meshed, which I longed to see.

But by the turn of the eighteenth century it was becoming clear across Europe that a rapid evolution in thought was under way. In part this was the result of scientific advance: the dethroning of the Ptolemaic view of the universe described by Smith, in favour of the heliocentric view of Copernicus and his followers; the astonishing discoveries of Newton; major mathematical developments by Descartes in geometry, and Leibniz and Newton with the calculus; the invention of the telescope and microscope, and the new natural philosophy of Galileo, Boyle and Hooke. But these achievements in turn betokened a much wider intellectual, social and cultural realignment, away from religion, deference to institutions and received wisdom and towards individual reason, scepticism and the exchange of ideas. In due course they led to calls for religious toleration, legal rights and moral equality that many princes and governments across Europe found profoundly threatening.

The fMRI scan allows scientists to locate the presence of oxygen contained within hemoglobin in the blood. Since oxygenated hemoglobin contains the energy that fuels cell activity, detecting the flow of this oxygen allows one to trace the flow of thoughts in the brain. Joshua Freedman, a psychiatrist at the University of California, Los Angeles, says: “It’s like being an astronomer in the sixteenth century after the invention of the telescope. For millennia, very smart people tried to make sense of what was going on up in the heavens, but they could only speculate about what lay beyond unaided human vision. Then, suddenly, a new technology let them see directly what was there.” In fact, fMRI scans can even detect the motion of thoughts in the living brain to a resolution of .1 millimeter, or smaller than the head of a pin, which corresponds to perhaps a few thousand neurons.

Some astronomers suggested that these mysterious objects were sprinkled throughout the universe. The majority, however, believed that they were more mundane entities within our own Milky Way. After all, William Herschel had indicated that everything was within our pancake-shaped Milky Way. The study of nebulae dates back to the ancient astronomers, who had spotted a handful of nebulae using just their naked eyes, but then the invention of the telescope revealed a surprisingly large number of them. The first person to compile a detailed catalogue of nebulae was the French astronomer Charles Messier, who started work on this project in 1764. Previously he had already been successful in tracking down comets, which is why King Louis XV nicknamed him the Comet Ferret, but Messier was continually frustrated because, at first sight, it was easy to confuse a comet with a nebula as both types of object appear as tiny smudges in the sky.

However, when the best rule’s performance is evaluated with the appropriate probability density function it does not appear statistically significant. That is to say, the rule’s rather high performance would not warrant the conclusion that it has predictive power or an expected return that is greater than zero. THE NEED FOR RIGOROUS STATISTICAL ANALYSIS The tools and methods of a discipline limit what it can discover. Improvements in them pave the way to greater knowledge. Astronomy took a great leap forward with the invention of the telescope. Though crude by today’s standards, the earliest instruments had 10 times the resolving power of the unaided eye. Technical analysis has a similar opportunity, but it must replace informal data analysis with rigorous statistical methods. Informal data analysis is simply not up to the task of extracting valid knowledge from financial markets. The data blossoms with illusory patterns whereas valid patterns are veiled by noise and complexity.

There are many ramifications of the increasing order and complexity that have resulted from biological evolution and its continuation through technology. Consider the boundaries of observation. Early biological life could observe local events several millimeters away, using chemical gradients. When sighted animals evolved, they were able to observe events that were miles away. With the invention of the telescope, humans could see other galaxies millions of light-years away. Conversely, using microscopes, they could also see cellular-size structures. Today humans armed with contemporary technology can see to the edge of the observable universe, a distance of more than thirteen billion light-years, and down to quantum-scale subatomic particles. Consider the duration of observation. Single-cell animals could remember events for seconds, based on chemical reactions.

“There is some evidence that Sirius once turned red.” “Red, Captain?” “Yes, sir. There are records of old astronomers recording Sirius as having a red coloration.” “When was this?” “Sir, eh, 150 BC was the first recorded instance.” “Are you joking, Captain?” “Sir, no sir. There have been several such inconsistencies in astronomical accounts in early history. They all happened prior to the invention of the telescope, so there’s no modern verifiable proof available. But the legend persisted for some time. There was even a tribe in Africa that supposedly knew about Sirius B centuries before telescopes confirmed its existence.” “I’m glad you’re doing your homework, Captain, but exactly how is this folklore relevant?” “Two things, sir.” She glanced up at the pane as the center’s AI bracketed a newly emerging sunspot.
