Newton Famous Quotes

This is how great intellectual breakthroughs usually happen in practice. It is rarely the isolated genius having a eureka moment alone in the lab. Nor is it merely a question of building on precedent, of standing on the shoulders of giants, in Newton's famous phrase. Great breakthroughs are closer to what happens in a flood plain: a dozen separate tributaries converge, and the rising waters lift the genius high enough that he or she can see around the conceptual obstructions of the age.

Sir Isaac Newton famously said that he had achieved everything by standing on the shoulders of giants—the scientific men whose findings he built upon. The same might be said about silicon. After germanium did all the work, silicon became an icon, and germanium was banished to periodic table obscurity.

Think about the most famous geniuses in history: Einstein, Newton, Galileo, Darwin, da Vinci, Mozart. What do they have in common?” Charlie reflected on that for a moment. “They’re all men.

If my name were Isaac Newton, would I be a famous no name? I’d have worldwide and historical name recognition, yet I’d be anonymous.

In Isaac Newton’s lifetime, no more than a few thousand people had any idea what he looked like, though he was one of England’s most famous men, yet now millions of people have quite a clear idea—based on replicas of copies of rather poorly painted portraits. Even more pervasive and indelible are the smile of Mona Lisa, The Scream of Edvard Munch, and the silhouettes of various fictional extraterrestrials. These are memes, living a life of their own, independent of any physical reality. “This may not be what George Washington looked like then,” a tour guide was overheard saying of the Gilbert Stuart painting at the Metropolitan Museum of Art, “but this is what he looks like now.” Exactly.

Albert Einstein, considered the most influential person of the 20th century, was four years old before he could speak and seven before he could read. His parents thought he was retarded. He spoke haltingly until age nine. He was advised by a teacher to drop out of grade school: “You’ll never amount to anything, Einstein.” Isaac Newton, the scientist who invented modern-day physics, did poorly in math. Patricia Polacco, a prolific children’s author and illustrator, didn’t learn to read until she was 14. Henry Ford, who developed the famous Model-T car and started Ford Motor Company, barely made it through high school. Lucille Ball, famous comedian and star of I Love Lucy, was once dismissed from drama school for being too quiet and shy. Pablo Picasso, one of the great artists of all time, was pulled out of school at age 10 because he was doing so poorly. A tutor hired by Pablo’s father gave up on Pablo. Ludwig van Beethoven was one of the world’s great composers. His music teacher once said of him, “As a composer, he is hopeless.” Wernher von Braun, the world-renowned mathematician, flunked ninth-grade algebra. Agatha Christie, the world’s best-known mystery writer and all-time bestselling author other than William Shakespeare of any genre, struggled to learn to read because of dyslexia. Winston Churchill, famous English prime minister, failed the sixth grade.

Newton had conceived of light as primarily a stream of emitted particles. But by Einstein’s day, most scientists accepted the rival theory, propounded by Newton’s contemporary Christiaan Huygens, that light should be considered a wave. A wide variety of experiments had confirmed the wave theory by the late nineteenth century. For example, Thomas Young did a famous experiment, now replicated by high school students, showing how light passing through two slits produces an interference pattern that resembles that of water waves going through two slits. In each case, the crests and troughs of the waves emanating from each slit reinforce each other in some places and cancel each other out in some places.

Newton was a decidedly odd figure – brilliant beyond measure, but solitary, joyless, prickly to the point of paranoia, famously distracted (upon swinging his feet out of bed in the morning he would reportedly sometimes sit for hours, immobilized by the sudden rush of thoughts to his head), and capable of the most riveting strangeness. He built his own laboratory, the first at Cambridge, but then engaged in the most bizarre experiments. Once he inserted a bodkin – a long needle of the sort used for sewing leather – into his eye socket and rubbed it around ‘betwixt my eye and the bone4 as near to [the] backside of my eye as I could’ just to see what would happen. What happened, miraculously, was nothing – at least, nothing lasting. On another occasion, he stared at the Sun for as long as he could bear, to determine what effect it would have upon his vision. Again he escaped lasting damage, though he had to spend some days in a darkened room before his eyes forgave him.

Descartes, whose arguments are of just the same sort as those of early Greek philosophers, said that extension is the essence of matter, and therefore there is matter everywhere. For him, extension is an adjective, not a substantive; its substantive is matter, and without its substantive it cannot exist. Empty space, to him, is as absurd as happiness without a sentient being who is happy. Leibniz, on somewhat different grounds, also believed in the plenum, but he maintained that space is merely a system of relations. On this subject there was a famous controversy between him and Newton, the latter represented by Clarke. The controversy remained undecided until the time of Einstein, whose theory conclusively gave the victory to Leibniz. The modern physicist, while he still believes that matter is in some sense atomic, does not believe in empty space. Where there is not matter, there is still something, notably light-waves. Matter no longer has the lofty status that it acquired in philosophy through the arguments of Parmenides. It is not unchanging substance, but merely a way of grouping events. Some events belong to groups that can be regarded as material things; others, such as light-waves, do not. It is the events that are the stuff of the world, and each of them is of brief duration. In this respect, modern physics is on the side of Heraclitus as against Parmenides. But it was on the side of Parmenides until Einstein and quantum theory.

In about 1980, he says, at a time when he was still struggling to articulate his own vision of a dynamic, evolving economy, he happened to read a book by the geneticist Richard Lewontin. And he was struck by a passage in which Lewontin said that scientists come in two types. Scientists of the first type see the world as being basically in equilibrium. And if untidy forces sometimes push a system slightly out of equilibrium, then they feel the whole trick is to push it back again. Lewontin called these scientists "Platonists," after the renowned Athenian philosopher who declared that the messy, imperfect objects we see around us are merely the reflections of perfect "archetypes." Scientists of the second type, however, see the world as a process of flow and change, with the same material constantly going around and around in endless combinations. Lewontin called these scientists "Heraclitans," after the Ionian philosopher who passionately and poetically argued that the world is in a constant state of flux. Heraclitus, who lived nearly a century before Plato, is famous for observing that "Upon those who step into the same rivers flow other and yet other waters," a statement that Plato himself paraphrased as "You can never step into the same river twice." "When I read what Lewontin said," says Arthur, "it was a moment of revelation. That's when it finally became clear to me what was going on. I thought to myself, "Yes! We're finally beginning to recover from Newton.

The concept of absolute time—meaning a time that exists in “reality” and tick-tocks along independent of any observations of it—had been a mainstay of physics ever since Newton had made it a premise of his Principia 216 years earlier. The same was true for absolute space and distance. “Absolute, true, and mathematical time, of itself and from its own nature, flows equably without relation to anything external,” he famously wrote in Book 1 of the Principia. “Absolute space, in its own nature, without relation to anything external, remains always similar and immovable.” But even Newton seemed discomforted by the fact that these concepts could not be directly observed. “Absolute time is not an object of perception,” he admitted. He resorted to relying on the presence of God to get him out of the dilemma. “The Deity endures forever and is everywhere present, and by existing always and everywhere, He constitutes duration and space.”45 Ernst Mach, whose books had influenced Einstein and his fellow members of the Olympia Academy, lambasted Newton’s notion of absolute time as a “useless metaphysical concept” that “cannot be produced in experience.” Newton, he charged, “acted contrary to his expressed intention only to investigate actual facts.”46 Henri Poincaré also pointed out the weakness of Newton’s concept of absolute time in his book Science and Hypothesis, another favorite of the Olympia Academy. “Not only do we have no direct intuition of the equality of two times, we do not even have one of the simultaneity of two events occurring in different places,” he wrote.

From science, then, if it must be so, let man learn the philosophic truth that there is no material universe; its warp and woof is maya, illusion. Its mirages of reality all break down under analysis. As one by one the reassuring props of a physical cosmos crash beneath him, man dimly perceives his idolatrous reliance, his past transgression of the divine command: “Thou shalt have no other gods before Me.” In his famous equation outlining the equivalence of mass and energy, Einstein proved that the energy in any particle of matter is equal to its mass or weight multiplied by the square of the velocity of light. The release of the atomic energies is brought about through the annihilation of the material particles. The ‘death’ of matter has been the ‘birth’ of an Atomic Age. Light-velocity is a mathematical standard or constant not because there is an absolute value in 186,000 miles a second, but because no material body, whose mass increases with its velocity, can ever attain the velocity of light. Stated another way: only a material body whose mass is infinite could equal the velocity of light. This conception brings us to the law of miracles. The masters who are able to materialise and dematerialise their bodies or any other object and to move with the velocity of light, and to utilise the creative light-rays in bringing into instant visibility any physical manifestation, have fulfilled the necessary Einsteinian condition: their mass is infinite. The consciousness of a perfected yogi is effortlessly identified, not with a narrow body, but with the universal structure. Gravitation, whether the ‘force’ of Newton or the Einsteinian ‘manifestation of inertia’, is powerless to compel a master to exhibit the property of ‘weight’ which is the distinguishing gravitational condition of all material objects. He who knows himself as the omnipresent Spirit is subject no longer to the rigidities of a body in time and space. Their imprisoning ‘rings-pass-not’ have yielded to the solvent: “I am He.

Think of Sir Isaac Newton. He spent two years working on what became Principia Mathematica, his famous writings on universal gravitation and the three laws of motion. This period of almost solitary confinement proved critical in what became a true breakthrough that shaped scientific thinking for the next three hundred years.

The most famous story about gravity involves Isaac Newton and an apple that supposedly fell on his head, inspiring him to concoct his theory of universal gravitation. (It’s mostly famous because Newton himself couldn’t stop telling it later in life, in an unnecessary attempt to add some extra juice to his reputation as a genius.)

Of Sir Isaac Newton’s momentous decipherment of the laws of the universe, the French scientist Pierre-Simon de Laplace famously told Napoleon, in his philosophical euphoria, that he no longer had need of God to make sense of creation. Secular science could henceforth exile God from his universe. In Joseph Smith’s conception, by contrast, naturalism and God co-exist.

In this chapter we will look at the entire edifice of QFT. We will see that it is based on three simple principles. We will also list some of its achievements, including some new insights and understandings not previously mentioned. THE FOUNDATION QFT is an axiomatic theory that rests on a few basic assumptions. Everything you have learned so far, from the force of gravity to the spectrum of hydrogen, follows almost inevitably from these three basic principles. (To my knowledge, Julian Schwinger is the only person who has presented QFT in this axiomatic way, at least in the amazing courses he taught at Harvard University in the 1950's.) 1. The field principle. The first pillar is the assumption that nature is made of fields. These fields are embedded in what physicists call flat or Euclidean three-dimensional space-the kind of space that you intuitively believe in. Each field consists of a set of physical properties at every point of space, with equations that describe how these particles or field intensities influence each other and change with time. In QFT there are no particles, no round balls, no sharp edges. You should remember, however, that the idea of fields that permeate space is not intuitive. It eluded Newton, who could not accept action-at-a-distance. It wasn't until 1845 that Faraday, inspired by patterns of iron filings, first conceived of fields. The use of colors is my attempt to make the field picture more palatable. 2. The quantum principle (discetization). The quantum principle is the second pillar, following from Planck's 1900 proposal that EM fields are made up of discrete pieces. In QFT, all physical properties are treated as having discrete values. Even field strengths, whose values are continues, are regarded as the limit of increasingly finer discrete values. The principle of discretization was discovered experimentally in 1922 by Otto Stern and Walther Gerlach. Their experiment (Fig. 7-1) showed that the angular momentum (or spin) of the electron in a given direction can have only two values: +1/2 or -1/2 (Fig. 7-1). The principle of discretization leads to another important difference between quantum and classical fields: the principle of superposition. Because the angular momentum along a certain axis can only have discrete values (Fig. 7-1), this means that atoms whose angular momentum has been determined along a different axis are in a superposition of states defined by the axis of the magnet. This same superposition principle applies to quantum fields: the field intensity at a point can be a superposition of values. And just as interaction of the atom with a magnet "selects" one of the values with corresponding probabilities, so "measurement" of field intensity at a point will select one of the possible values with corresponding probability (see "Field Collapse" in Chapter 8). It is discretization and superposition that lead to Hilbert space as the mathematical language of QFT. 3. The relativity principle. There is one more fundamental assumption-that the field equations must be the same for all uniformly-moving observers. This is known as the Principle of Relativity, famously enunciated by Einstein in 1905 (see Appendix A). Relativistic invariance is built into QFT as the third pillar. QFT is the only theory that combines the relativity and quantum principles.

The truth was that Newton’s biblical research was central to his entire scientific career. They form the essential backdrop for his most famous work, the Principia Mathematica.

Whether the real setting and dating of the Hermetic tradition in late antiquity are, in fact, irrelevant to its reception in the Renaissance is an interesting hermeneutic question that cannot be answered here. In any case and for many other reasons, Yates’s views on the Hermetica became famous for some, notorious for others, especially when, in a 1968 article, she made Hermes a major figure in the preliminaries to the scientific revolution, just two years after J.E. McGuire and P.M. Rattansi had connected Newton’s physics with the ancient theology theme so closely associated with Hermes.

But in 1936 a huge archive of Newton’s private manuscripts was put up for auction at Sotheby’s, in London. The papers had been kept from the public for over two centuries. One hundred lots of the manuscripts were bought by the famous British economist, John Maynard Keynes, who found that many of Newton’s papers were written in a secret cypher. And for six years, Keynes struggled to decipher them. He hoped they would reveal the private thoughts of the founder of modern science. But what the code really revealed was another, far darker, side to Newton’s work. For, in the manuscripts, Keynes found a Newton unknown to the rest of the world—a Newton obsessed with religion, and a purveyor of practices of heresy and the occult.

Newton’s own goal was to demonstrate the dependence of matter on God.10 He did this through his revolutionary concept of force. Nature as described in the Principia is a complex matrix of forces, from centripetal and centrifugal force, to magnetic force and inertial force (as in, “Bodies at rest tend to remain at rest”), to the most famous of all, the force of gravity. These forces, Newton showed, exert a palpable and mathematically predictable influence on the behavior of all physical bodies. Yet they are entirely invisible and beyond any purely physical or mechanical explanation.

Sir Isaac Newton legendarily wrote the famous Philosophiæ Naturalis Principia Mathematica, which gave us principles that a couple of hundred years later were good enough to land a man on the moon. Then he wrote the slightly less well known Philosophiæ Naturalis Principia Artes Magicis, which codified the magical techniques that allow me to inconvenience paper targets and Nightingale to demolish small agricultural buildings. “There

For the man on the street, science and math sound too and soulless. It is hard to appreciate their significance Most of us are just aware of Newton's apple trivia and Einstein's famous e mc2. Science, like philosophy, remains obscure and detached, playing role in our daily lives. There is a general perception that science is hard to grasp and has direct relevance to what we do. After all, how often do we discuss Dante or Descartes over dinner anyway? Some feel it to be too academic and leave it to the intellectuals or scientists to sort out while others feel that such topics are good only for academic debate. The great physicist, Rutherford, once quipped that, "i you can't explain a complex theory to a bartender, the theory not worth it" Well, it could be easier said than done (applications of tools

In any society, the mind “at first . . . is rasa tabula,” Locke famously wrote in An Essay Concerning Humane Understanding. If people are born without innate intelligence, then there cannot be a natural intellectual hierarchy. But Locke’s egalitarian idea had a caveat. As Boyle and Newton painted unblemished light white, Locke more or less painted the unblemished mind white. Locke used the term “white paper” much more often than “blank slate” or “tabula rasa” to describe the child’s “as yet unprejudiced Understanding.

Second, the warning against insatiable desires makes more sense with respect to some desires, less sense with respect to others. It seems most reasonable when the object of desire is something like territorial conquests, wealth, power, fame, glory, influence, sex, expensive art objects, fancy clothes, sports cars, and so on. But what if the object of desire is knowledge, understanding, artistic satisfaction, the eradication of a disease, or the elimination of injustice? Is the fact that these desires cannot be finally satisfied a reason for reining them in? Isaac Newton famously lamented that his quest for insight into the nature of things could be compared to the actions of a boy playing on the seashore “whilst the great ocean of truth lay all undiscovered before me.” Would it have been better for him to have kept his desire for understanding in check so as to avoid this abiding feeling of disappointment? The accomplished and acclaimed novelist Zadie Smith offers this advice to fellow writers: “Resign yourself to the lifelong sadness that comes from never being satisfied.”28 Should she, instead, advise her readers never to even try? This argument can be taken in two ways. One way is to see it as supporting the previous objection: there are kinds of pleasure and happiness that are invariably tied to feelings of dissatisfaction, and the Epicurean guidelines fail to appreciate this. The other way is to see it as placing a question mark against the prioritizing of happiness. The insatiable desire of Newton for understanding, of Beethoven for adequate artistic expression, of Shackleton for adventure, or of Harriet Tubman for justice may not have brought them happiness; it may even have interfered with their capacity to be happy. But such examples remind us that happiness may not always be a rational person’s primary goal.

Isaac Newton famously noted that an object in motion tends to stay in motion, while an object at rest tends to stay at rest. Sir Isaac focused on physical objects—planets, pendulums, and the like—but the same concepts can be applied to the social world. Just like moons and comets, people and organizations are guided by conservation of momentum. Inertia. They tend to do what they’ve always done.

Reviewed by Vincent Dublado for Readers' Favorite Another Time in a Vacuum by Roland Burisch is a witty fantasy adventure of anachronistic proportions. Meet Monty, a timetraveling historian who travels back to 1673. Imagine the thrill of excitement that greets him as he meets one of history’s most important diarists, Samuel Pepys. He musters the courage to tell Pepys that he has important information, but the eminent diarist is suspicious that he could be an extortionist. Monty tells Pepys that he is from the future and that he is familiar with the contents of Pepys’s diaries. Monty introduces the diarist to his mobile phone to lend authenticity to his claim. Monty remembers that Sir Isaac Newton is alive in the same period, with which Pepys concurs, unless Newton is beheaded for heresy. But Monty tells him that Newton will go down in history for his work. This fills Pepys with disbelief. Monty brings the two men into the present, and these two historical figures will witness the contemporary period with awe and bewilderment, an adventure that they will fill with many questions. Another Time in a Vacuum is a fascinating time-travel adventure that is intelligent, witty, and at times, sad. While this novel takes the idea of time travel as an essential element in the storyline, it is more about a comparative look at the lifestyle and norms of the past with the present. It is inevitable that the two famous men will not understand Monty initially. But Roland Burisch equips his plot with confidence in the intelligence of Pepys and Newton. They eventually understand why Monty exists in their time without many ramifications about the historical timeline getting altered. Burisch wisely hinges on the mechanics of dialogue and the interaction of the trio for the plot. It is also one of the reasons why this novel works because you like the quirks of the characters. They are wise, funny, and fish out of water. It sounds like a story that you will enjoy reading. It is.

Saunderson lectured on light, lenses, optics, the phenomenon of the rainbow, and other subjects connected with sight. He also helped to make Newton's theories of the Principia Mathematica and other works accessible to students of Cambridge. Unlike Newton, however, Saunderson was famously (or infamously) irreligious, which adds another layer to Diderot's interest in this blind man.

Newton spent under quarantine at home in rural Lincolnshire, sheltering from the Plague that was ravaging his chosen home cities of London and Cambridge, has come to be thought of today as his annus mirabilis – his ‘year of wonders’. It’s when he formulated what would become calculus and the laws of motion, for example, and it’s when he worked out the nature of light – this is when he performed his famous prism experiment that demonstrated how white light could be split into all the colours of the rainbow, a discovery so monumental that it would later be memorialised on a Pink Floyd album cover.

Goethe refused to view color as a static quantity, to be measured in a spectrometer and pinned down like a butterfly to cardboard. He argued that color is a matter of perception. “With light poise and counterpoise, Nature oscillates within her prescribed limits,” he wrote, “yet thus arise all the varieties and conditions of the phenomena which are presented to us in space and time.” The touchstone of Newton’s theory was his famous experiment with a prism. A prism breaks a beam of white light into a rainbow of colors, spread across the whole visible spectrum, and Newton realized that those pure colors must be the elementary components that add to produce white. Further, with a leap of insight, he proposed that the colors corresponded to frequencies. He imagined that some vibrating bodies—corpuscles was the antique word—must be producing colors in proportion to the speed of the vibrations. Considering how little evidence supported this notion, it was as unjustifiable as it was brilliant. What is red? To a physicist, it is light radiating in waves between 620 to 800 billionths of a meter long. Newton’s optics proved themselves a thousand times over, while Goethe’s treatise on color faded into merciful obscurity.

John Newton, the repentant former slaver, preached the gospel in his parish of Olney; created the Eclectic Society, whose members asked questions like “What is the best way of propagating the Gospel in the East Indies?”; and penned the famous lyrics of “Amazing Grace”: “Amazing grace, how sweet the sound, That saved a wretch like me. I once was lost, but now am found, was blind but now I see.

George Mumford, a Newton-based mindfulness teacher, one such moment took place in 1993, at the Omega Institute, a holistic learning center in Rhinebeck, New York. The center was hosting a retreat devoted to mindfulness meditation, the clear-your-head habit in which participants sit quietly and focus on their breathing. Leading the session: meditation megastar Jon Kabat-Zinn. Originally trained as a molecular biologist at MIT, Kabat-Zinn had gone on to revolutionize the meditation world in the 1970s by creating a more secularized version of the practice, one focused less on Buddhism and more on stress reduction and other health benefits. After dinner one night, Kabat-Zinn was giving a talk about his work, clicking through a slide show to give the audience something to look at. At one point he displayed a slide of Mumford. Mumford had been a star high school basketball player who’d subsequently hit hard times as a heroin addict, Kabat-Zinn explained. By the early 1980s, however, he’d embraced meditation and gotten sober. Now Mumford taught meditation to prison inmates and other unlikely students. Kabat-Zinn explained how they were able to relate to Mumford because of his tough upbringing, his openness about his addiction — and because, like many inmates, he’s African-American. Kabat-Zinn’s description of Mumford didn’t seem to affect most Omega visitors, but one participant immediately took notice: June Jackson, whose husband had just coached the Chicago Bulls to their third consecutive NBA championship. Phil Jackson had spent years studying Buddhism and Native American spirituality and was a devoted meditator. Yet his efforts to get Michael Jordan, Scottie Pippen, and their teammates to embrace mindfulness was meeting with only limited success. “June took one look at George and said, ‘He could totally connect with Phil’s players,’ ’’ Kabat-Zinn recalls. So he provided an introduction. Soon Mumford was in Chicago, gathering some of the world’s most famous athletes in a darkened room and telling them to focus on their breathing. Mumford spent the next five years working with the Bulls, frequently sitting behind the bench, as they won three more championships. In 1999 Mumford followed Phil Jackson to the Los Angeles Lakers, where he helped turn Kobe Bryant into an outspoken adherent of meditation. Last year, as Jackson began rebuilding the moribund New York Knicks as president, Mumford signed on for a third tour of duty. He won’t speak about the specific work he’s doing in New York, but it surely involves helping a new team adjust to Jackson’s sensibilities, his controversial triangle offense, and the particular stress that comes with compiling the worst record in the NBA. Late one April afternoon just as the NBA playoffs are beginning, Mumford is sitting at a table in O’Hara’s, a Newton pub. Sober for more than 30 years, he sips Perrier. It’s Marathon Monday, and as police begin allowing traffic back onto Commonwealth Avenue, early finishers surround us, un-showered and drinking beer. No one recognizes Mumford, but that’s hardly unusual. While most NBA fans are aware that Jackson is serious about meditation — his nickname is the Zen Master — few outside his locker rooms can name the consultant he employs. And Mumford hasn’t done much to change that. He has no office and does no marketing, and his recently launched website, mindfulathlete.org, is mired deep in search-engine results. Mumford has worked with teams that have won six championships, but, one friend jokes, he remains the world’s most famous completely unknown meditation teacher. That may soon change. This month, Mumford published his first book, The Mindful Athlete, which is part memoir and part instruction guide, and he has agreed to give a series of talks and book signings

As Sir Isaac Newton famously confessed after losing a small fortune in the stock market in the early 1700s, "I can calculate the motions of heavenly bodies, but not the madness of peopole.
