Physics Quotes

Understanding how DNA transmits all it knows about cancer, physics, dreaming and love will keep man searching for some time. ~ David R. Brower

Physics says: go to sleep. Of course you're tired. Every atom in you has been dancing the shimmy in silver shoes nonstop from mitosis to now. Quit tapping your feet. They'll dance inside themselves without you. ~ Albert Goldbarth

Given everything we know about the universe it would seem utterly impossible for any sane person to believe that the ultimate truth about the universe and human existence is the story of Israeli, German or Russian nationalism – or indeed of nationalism in general. A story that ignores almost the whole of time, the whole of space, the Big Bang, quantum physics and the evolution of life is at most just a tiny part of the truth. Yet people somehow manage not to see beyond it.
Indeed, billions of people throughout history have believed that for their lives to have meaning, they don't even need to be absorbed into a nation or a great ideological movement. It is enough if they just 'leave something behind', thereby ensuring that their personal story continues beyond their death. The 'something' I leave behind is ideally my soul or my personal essence. If I am reborn in a new body after the death of my present body, then death is not the end. It is merely the space between two chapters, and the plot

"that began in one chapter will carry on into the next. Many people have at least a vague faith in such a theory, even if they do not base it on any specific theology. They don't need an elaborate dogma – they just need the reassuring feeling that their story continues beyond the horizon of death. ~ Yuval Noah Harari

I became a physicist to understand the world, then I became a writer to try and change it. ~ Carla H. Krueger

Mathematics catalogues everything that is not self-contradictory; within that vast inventory, physics is an island of structures rich enough to contain their own beholders. ~ Greg Egan

The laws of physics that deal with inertia also apply to humans, such that situations tend to remain the same over time. ~ Del Suggs

Physics is like sex: sure, it may give some practical results, but that's not why we do it. ~ Richard Feynman

From age 16 on, I found school boring and failed A-level Physics at my first attempt. This was necessary for university entrance, and so I stayed an extra year to repeat it. This time, I did splendidly and was admitted to Sheffield University, my first choice because of their excellent Chemistry Department. ~ Richard J. Roberts

Of course, even without my help, other forces would keep the cosmos chugging along. Many different belief systems powered the revolution of the planets and stars. Wolves would still chase Sol across the sky. Ra would continue his daily journey in his sun barque. Tonatiuh would keep running on his surplus blood from human sacrifices back in the Aztec days. And that other thing - science - would still generate gravity and quantum physics or whatever. ~ Rick Riordan

What, after all, is so special about genes? The answer is that they are replicators. The laws of physics are supposed to be true all over the accessible universe. Are there any principles of biology which are likely to have similar universal validity? When astronauts voyage to distant planets and look for life, they can expect to find creatures too strange and unearthly for us to imagine. But is there anything which must be true of all life, wherever it is found, and whatever the basis of its chemistry? If forms of life exist whose chemistry is based on silicon rather than carbon, or ammonia rather than water, if creatures are discovered which boil to death at -100 degrees centigrade, if a form of life is found which is not based on chemistry at all, but on electronic reverberating circuits, will there still be any general principle which is true of all life? Obviously I do not know but, if I had to bet, I would put my money on one fundamental principle. This is the law that all life evolves by the differential survival of replicating entities. The gene, the DNA molecule, happens to be the replicating entity which prevails on our own planet. There may be others. If there are, provided certain conditions are met, they will almost inevitably tend to becomethe basis for an evolutionary process. ~ Richard Dawkins

People want to think of economics as a natural science, like physics, with the comforting reliability of simple-to-understand theories like F=MA. Unfortunately, it isn't. Economics is a social science, and the so-called theories are really social and moral constructs. ~ Nick Hanauer

During our glorious year of 1974–5, while I was dithering over gravitational waves, and Stephen was leading our merged group in black hole research, Stephen himself had an insight even more radical than his discovery of Hawking radiation. He gave a compelling, almost airtight proof that, when a black hole forms and then subsequently evaporates away completely by emitting radiation, the information that went into the black hole cannot come back out. Information is inevitably lost.
This is radical because the laws of quantum physics insist unequivocally that information can never get totally lost. So, if Stephen was right, black holes violate a most fundamental quantum mechanical law.
How could this be? The black hole's evaporation is governed by the combined laws of quantum mechanics and general relativity - the ill-understood laws of quantum gravity; and so, Stephen reasoned, the fiery marriage of relativity and quantum physics must lead to information destruction.
The great majority of theoretical physicists find this conclusion abhorrent. They are highly sceptical. And so, for forty-four years they have struggled with this so-called information-loss paradox. It is a struggle well worth the effort and anguish that have gone into it, since this paradox is a powerful key for understanding the quantum gravity laws. Stephen himself, in 2003, found a way that information might escape during the hole's evaporation, but that did not quell theorists' struggles. Stephe ~ Stephen Hawking

Insofar as he makes use of his healthy senses, man himself is the best and most exact scientific instrument possible. The greatest misfortune of modern physics is that its experiments have been set apart from man, as it were, physics refuses to recognize nature in anything not shown by artificial instruments, and even uses this as a measure of its accomplishments. ~ Johann Wolfgang Von Goethe

Kaluza also gave an answer as to where the fifth dimension was. Since we see no evidence of a fifth dimension, it must have "curled up" so small that it cannot be observed. (Imagine taking a two-dimensional sheet of paper and rolling it up tightly into a cylinder. From a distance, the cylinder looks like a one-dimensional line. In this way, a two-dimensional object has been turned into a one-dimensional object by curling it up.)

Kaluza's paper initially created a sensation. But in the coming years, objections were found to his theory. What was the size of this new fifth dimension? How did it curl up? No answers could be found.

For decades Einstein would work on this theory in fits and starts. After he passed away in 1955, the theory was soon forgotten, becoming just a strange footnote to the evolution of physics. ~ Michio Kaku

Those sages of the ancient world, unbound by dogma of any kind, thought as we do in terms of physics, or rather, physiology, as applied to the whole universe: they envisaged the end of man and the dying out of this sphere. ~ Marguerite Yourcenar

The laws of Congress and the laws of physics have grown increasingly divergent, and the laws of physics are not likely to yield. ~ Bill McKibben

All high mathematics serves to do is to beget higher mathematics. ~ Ashim Shanker

Physics is to math what sex is to masturbation. ~ Richard Feynman

History, Geology, Psychology, Philosophy, Chemistry, Physics, Theology, Mathematics, Technology, Sociology, Biology, and the list goes on and on. If all this body of knowledge exist for human consumption, why would I specialize in only one field? ~ Allan Amanyire

Inertia is the first law of history, as it is of physics. ~ Morris Raphael Cohen

I started out in nuclear physics. But after I became more sensitized to the environmental and health implications of the nuclear system - I was being trained to be the first women in the fast-breeder reactor in India (and was in it when it first went critical) - I didn't feel comfortable with it. So I went into theoretical physics. ~ Vandana Shiva

I'm fascinated with quantum physics. ~ Will.i.am

The qualifications that I have to speak on world affairs are exactly the same ones Henry Kissinger has, and Walt Rostow has, or anybody in the Political Science Department, professional historians - none, none that you don't have. The only difference is, I don't pretend to have qualifications, nor do I pretend that qualifications are needed. I mean, if somebody were to ask me to give a talk on quantum physics, I'd refuse - because I don't understand enough. But world affairs are trivial: there's nothing in the social sciences or history or whatever that is beyond the intellectual capacities of an ordinary fifteen-year-old. You have to do a little work, you have to do some reading, you have to be able to think but there's nothing deep - if there are any theories around that require some special kind of training to understand, then they've been kept a carefully guarded secret. ~ Noam Chomsky

I think that the discovery of antimatter was perhaps the biggest jump of all the big jumps in physics in our century. ~ Werner Heisenberg

But in the dynamic space of the living Rocket , the double integral has a different meaning. To integrate here is to operate on a rate of change so that time falls away: change is stilled ... 'Meters per second ' will integrate to 'meters.' The moving vehicle is frozen, in space, to become architecture, and timeless. It was never launched. It never did fall. ~ Thomas Pynchon

Recent studies have considered the detection of a spaceship visiting our parish of the galaxy. In my opinion that last thought should bring a blush to every human cheek ... Fecklessness might be the main theme of the aliens' report on the new-found source of radio pollution ... that emanates from beings who have mastered a lot of physics, chemistry and biology and yet let their children starve-while all around their planet the energy of their mother star runs to waste in a desert of space. ~ Nigel Calder

That aging alone, so different from its more youthful sister. That
aging alone, moves with a speed meant for quantum physics, or the
blurred lines of streetlamps in misting rain. ~ Alexx Bollen

In the beginning there was nothing, which exploded. ~ Terry Pratchett

One of the principal achievements of physics in the 20th century has been the revelation that the atom is not indivisible or elementary at all but has a complex structure. ~ Sheldon Lee Glashow

Something must be
very wrong,' it said,
and I agreed,
although it turned out
the author meant that 'no theory
of physics should produce
infinities with impunity.'
I'd point out that every theory
of the heart
produces infinities
with impunity
if I were the kind of jerk
who uses the heart
to mean the human
tendency to make
others suffer
just because we
hate to suffer
alone. I'm sorry
I brought a fitted sheet
to the beach. I'm sorry
I'm selfish and determined
to make the worst
of everything. I'm
sorry language is a ship
that goes down
while you're building it.
The Hesychasts of Byzantium
stripped their prayers
of words. It's been tried
with poems too. But insofar
as I am a disappointment
to myself and others, it seems fitting
to set up shop in almost
and not quite and that's not
what I meant. I draw the line at the heart,
though, with its
infinities. ~ Michael Robbins

QED [quantum electrodynamics] reduces ... "all of chemistry and most of physics," to one basic interaction, the fundamental coupling of a photon to electric charge. The strength of this coupling remains, however, as a pure number, the so-called fine-structure constant, which is a parameter of QED that QED itself is powerless to predict. ~ Frank Wilczek

I considered law and math. My Dad was a lawyer. I think though I would have ended up in physics if I didn't end up in computer science. ~ Bill Gates

When I was a young man, Dirac was my hero. He made a breakthrough, a new method of doing physics. He had the courage to simply guess at the form of an equation, the equation we now call the Dirac equation, and to try to interpret it afterwards. ~ Richard P. Feynman

What we mean when speaking of "myth" in general is story, the ability of story to explain ourselves to ourselves in ways that physics, philosophy, mathematics, chemistry - all very highly useful and informative in their own right - can't. ~ Thomas C. Foster

All the quantum physics experiments have occurred chiefly on the atomic scale and we are taught to believe that nature's laws are consistent. ~ Mitch Horowitz

There is apparently an easy test to distinguish good schoolteachers from poor ones; ask them what they teach. Poor ones reply, 'I teach French,' or 'I teach physics' or whatever their subject is. Good ones say, 'I teach children.' The teacher here would have fallen into the second group: he taught knowledge to people. Or better, he imparted knowledge, meaning he passed over so that the people who learned from him knew the lessons for themselves. ~ Chris Green

Evolution has just been dealt its death blow. After reading Origins of Life with my background in chemistry and physics, it is clear that biological evolution could not have occurred. ~ Richard Smalley

I have a problem with telling jokes about physics. Quite often the audience have no idea what you are talking about and, to be honest, I don't know what I'm talking about either. ~ Robin Ince

I have sold more books on physics than Madonna has on sex. ~ Stephen Hawking

The life force knows exactly what it takes to keep any particular living organism - any organism - alive. Anything in manifestation, for that matter. Even a rock is a manifestation of some sort, and you know, in physics and quantum physics, they know a rock is not dead. ~ Lindsay Wagner

Can there be a completely different set of laws of physics in a different universe, or do the laws of physics as we understand them hold true in all possible universes? If the answer is that a different set of laws can operate in a different universe system, this would suggest (from a Buddhist perspective) that even the laws of physics are entangled with the karma of the sentient beings that will arise in that universe. ~ Dalai Lama XIV

Whatever you want," he said. "Will you please come here now?"
I slipped a piece of protective tissue over my drawing and flipped the book closed. A piece of blue scratch paper slid out, the line I'd copied from Edward;s poetry book. "Hey. Translate for me, Monsieur Bainbridge."
I set the sketchbook on my stool and joined him on the chaise. He tugged me onto his lap and read over his head. "'Qu'ieu sui avinen, leu lo sai.' 'That I am handsome, I know."
"Verry funny."
"Very true." He grinned. "The translation. That's what it says. Old-fashionedly."
I thought of Edward's notation on the page, the reminder to read the poem to Diana in bed, and rolled my eyes. You're so vain.I bet you think this song is about you..."Boy and their egos."
Alex cupped my face in his hands. "Que tu est belle, tu le sais."
"Oh,I am not-"
"Shh," he shushed me, and leaned in.
The first bell came way too soon. I reluctantly loosened my grip on his shirt and ran my hands over my hair. He prompty thrust both hands in and messed it up again. "Stop," I scolded, but without much force.
"I have physics," he told me. "We're studying weak interaction."
I sandwiched his open hand between mine. "You know absolutely nothing about that."
"Don't be so quick to accept the obvious," he mock-scolded me. "Weak interaction can actually change the flavor of quarks."
The flavor of quirks, I thought, and vaguely remembered something about being charmed. I'd sat ~ Melissa Jensen

Chemistry, until my childhood, not that long ago, was regarded as a calculating device. Because you couldn't reduce to physics. So it's just some way of calculating the result of experiments. The Bohr atom was treated that way. ~ Noam Chomsky

Physics as we know it will be over in six months. ~ Max Born

So far as we know, all the fundamental laws of physics, like Newton's equations, are reversible. ~ Richard P. Feynman

In physics, you don't have to go around making trouble for yourself - nature does it for you. ~ Frank Wilczek

[...] It is. Philosophy is a field that, unfortunately, reminds me of that old Woody Allen joke, "those that can't do, teach, and those that can't teach, teach gym." And the worst part of philosophy is the philosophy of science; the only people, as far as I can tell, that read work by philosophers of science are other philosophers of science. It has no impact on physics what so ever, and I doubt that other philosophers read it because it's fairly technical. And so it's really hard to understand what justifies it. And so I'd say that this tension occurs because people in philosophy feel threatened, and they have every right to feel threatened, because science progresses and philosophy doesn't.
[the atlantic, Has Physics Made Philosophy and Religion Obsolete? - interview, apr 23 2012] ~ Lawrence M. Krauss

Life, just like the stars, the planets and the galaxies, is just a temporary structure on the long road from order to disorder. But that doesn't make us insignificant, because we are the Cosmos made conscious. Life is the means by which the universe understands itself. And for me, our true significance lies in our ability to understand and explore this beautiful universe. ~ Brian Cox

If and when all the laws governing physical phenomena are finally discovered, and all the empirical constants occurring in these laws are finally expressed through the four independent basic constants, we will be able to say that physical science has reached its end, that no excitement is left in further explorations, and that all that remains to a physicist is either tedious work on minor details or the self-educational study and adoration of the magnificence of the completed system. At that stage physical science will enter from the epoch of Columbus and Magellan into the epoch of the National Geographic Magazine! ~ George Gamow

Physics is to mathematics like sex is to masturbation. ~ Richard Feynman

This "Hawking temperature" of a black hole and its "Hawking radiation" (as they came to be called) were truly radical - perhaps the most radical theoretical physics discovery in the second half of the twentieth century. They opened our eyes to profound connections between general relativity (black holes), thermodynamics (the physics of heat) and quantum physics (the creation of particles where before there were none). For example, they led Stephen to prove that a black hole has entropy, which means that somewhere inside or around the black hole there is enormous randomness. He deduced that the amount of entropy (the logarithm of the hole's amount of randomness) is proportional to the hole's surface area. His formula for the entropy is engraved on Stephen's memorial stone at Gonville and Caius College in Cambridge, where he worked.
For the past forty-five years, Stephen and hundreds of other physicists have struggled to understand the precise nature of a black hole's randomness. It is a question that keeps on generating new insights about the marriage of quantum theory with general relativity - that is, about the ill-understood laws of quantum gravity. ~ Stephen Hawking

It's not an academic question any more to ask what's going to happen to a cloud. People very much want to know - and that means there's money available for it. That problem is very much within the realm of physics and it's a problem very much of the same caliber. You're looking at something complicated, and the present way of solving it is to try to look at as many points as you can, enough stuff to say where the cloud is, where the warm air is, what its velocity is, and so forth. Then you stick it into the biggest machine you can afford and you try to get an estimate of what it's going to do next. But this is not very realistic. ~ James Gleick

Chemistry has been termed by the physicist as the messy part of physics, but that is no reason why the physicists should be permitted to make a mess of chemistry when they invade it. ~ Frederick Soddy

And the actual achievements of biology are explanations in terms of mechanisms founded on physics and chemistry, which is not the same thing as explanations in terms of physics and chemistry. ~ Michael Polanyi

Ancient wisdom and quantum physicists make unlikely bedfellows: In quantum mechanics the observer determines (or even brings into being) what is observed, and so, too, for the Tiwis, who dissolve the distinction between themselves and the cosmos. In quantum physics, subatomic particles influence each other from a distance, and this tallies with the aboriginal view, in which people, animals, rocks, and trees all weave together in the same interwoven fabric. ~ Huston Smith

Failed a physics test," Nick said.
"You know how I solve that problem?" Said his twin. "I don't take physics. ~ Brigid Kemmerer

If you want to win this argument with Dad, look in chapter two of the first book of the Feynman Lectures on Physics. There's a quote there about how philosophers say a great deal about what science absolutely requires, and it is all wrong, because the only rule in science is that the final arbiter is observation - that you just have to look at the world and report what you see. Um ... off the top of my head I can't think of where to find something about how it's an ideal of science to settle things by experiment instead of arguments - ~ Eliezer Yudkowsky

While Newton seemed to draw off the veil from some of the mysteries of nature, he showed at the same time the imperfections of the mechanical philosophy, so agreeable to the natural vanity and curiosity of men; and thereby restored her ultimate secrets to that obscurity, in which they ever did and ever will remain. ~ David Hume

Einstein felt that he did not have great mathematical gifts and deliberately chose not to take courses and to continue in that area.

The fact that I neglected mathematics to a certain extent had its causes not merely in my stronger interest in science than in mathematics but also in the following strange experience....I saw that mathematics was split up into numerous specialties, each of which could easily absorb the short lifetime granted to us....In physics, however, I soon learned to scent out that which was able to lead to fundamentals and to turn aside from everything else, from the multitude of things that clutter up the mind and divert it from the essential.

This capacity to pick out important issues dovetailed with Einstein's search for the most general possible conception. "In a man of my type," he declared, "the turning point of the development lies in the fact that gradually the major interest disengages itself to a far reaching degree from the momentary and the merely personal and turns toward the striving for a mental grasp of things. ~ Howard Gardner

Konstantin Tsiolkovsky in Russia, Hermann Olberth in Germany, and Robert Goddard in the United States all came up with an eerily similar concept for using liquid fuel to power rockets for human spaceflight. I've seen this pointed out as an odd coincidence, one of those moments when an idea inexplicably emerges in multiple places at once. But when I read through each of these three men's biographies I discovered why they all had the same idea: all three of them were obsessed with Jules Verne's 1865 novel "De la terre a la lune (From the Earth to the Moon)." The novel details the strange adventures of three space explorers who travel to the moon together. What sets Verne's book apart from the other speculative fiction of the time was his careful attention to the physics involved in space travel -- his characters take pains to explain to each other exactly how and why each concept would work. All three real-life scientists -- the Russian, the German, and the American -- were following what they had learned from a French science fiction writer. ~ Margaret Lazarus Dean

The principle of vis inertiae ( ... ) seems to be identical in physics and metaphysics. It is not more true in the former, that a large body is with more difficulty set in motion than a smaller one, and that its subsequent momentum is commensurate with this difficulty, than it is, in the latter, that intellects of the vaster capacity, while more forcible, more constant, and more eventful in their movements than those of inferior grade, are yet the less readily moved, and more embarrassed, and full of hesitation in the first few steps of their progress ~ Edgar Allan Poe

Interest in alchemy seems to be nowadays on the rise. Whereas the educated public at large remains no doubt skeptical and indeed disdainful of the ancient discipline, there is today a deepening awareness among the better informed that what stands behind many an "exploded superstition" may be in fact a long-forgotten wisdom. Although Carl Jung was obviously exaggerating when ! he suggested that four centuries after being expelled from our universities,- alchemy stands "knocking at the door," a number of factors have conspired; to render the prospect of re-admission less remote, at least, than it had been ; during the heyday of materialism. In any case, no truly solid grounds for rejecting the ancient doctrine have yet been proposed. Take the case of the so-called four elements: earth, water, air and fire. One can be reasonably certain that these terms were not employed alchemically in their ordinary sense, but were used to designate elements, precisely, out of which substances, as we know them, are constituted. Somewhat like the quarks of modern physics, these elements are not found empirically in isolation, but occur in their multiple combinations, that is to say, as the perceptible substances that constitute what I term the corporeal domain. Now, as I have argued at length in The Quantum Enigma (Peru, Illinois: Sherwood Sugden, 1995), corporeal objects are not in fact mere aggregates of quantum particles; and this clearly suggests that there may indeed be elements of the afo ~ Wolfgang Smith

So you're an atheist and you say, "Well how do you know there's a God?" So what is there, nothing? So nothing created you? So you believe in nothing? Therefore, you believe in something – but that's nothing. You believe in nothingness. I believe in God. That's all. How can you believe in nothingness? How is it possible to believe in nothingness? How can something come from nothing? It's a violation of all the laws of physics! Something cannot come from nothing. It violates physical science, biological science, and theological science. It violates all the laws of reason! It violates all the laws of nonreason. ~ Michael Savage

The new coherent picture is not yet available. With all their immense empirical success, G(eneral)R(elativity) and Q(uantum)M(echanics) have left us with an understanding of the physical world which is unclear and badly fragmented. At the foundations of physics there is today confusion and incoherence. ~ Carlo Rovelli

Either theology is pure nonsense, a subject with no content, or else theology must ultimately become a branch of physics. ~ Frank Tipler

As physics is a mental reconstruction of material processes, perhaps a physical reconstruction of psychic processes is possible in nature itself. ~ Marie-Louise Von Franz

The various approximations that constitute our current physics theories are successful because simple mathematical structures can provide good approximations of how a self-aware substructure will perceive more complex mathematical structures. In other words, our successful theories are not mathematics approximating physics, but mathematics approximating mathematics! ~ Max Tegmark

When it came time for me to give my talk on the subject, I started off by drawing an outline of the cat and began to name the various muscles.
The other students in the class interrupt me: "We *know* all that!"
"Oh," I say, "you *do*? Then no *wonder* I can catch up with you so fast after you've had four years of biology." They had wasted all their time memorizing stuff like that, when it could be looked up in fifteen minutes. ~ Richard Feynman

When describing me, Tracy often refers to a well-known concept of physics: 'inertia.' As Newton avers in his first law: 'An object that is not moving will not move until a force acts upon it. An object that is moving will not change its velocity until a net force acts upon it.' In other words, depending on what's happening in my life at any given moment, I can either be the laziest human being on the planet, or the busiest. I'm perfectly content to do absolutely nothing until I'm catalyzed by some person or project, and then I go nonstop until some countervailing force acts upon me, and I revert back to static mode. ~ Michael J. Fox

In physics a system is said to have a symmetry if its properties are unaffected by a certain transformation such as rotating it in space or taking its mirror image. For example, if you flip a donut over, it looks exactly the same (unless it has a chocolate topping, in which case it is better just to eat it). ~ Stephen Hawking

If you look at the creation of the earth, you'll see that all the forces of physics combined to create an ebb and flow that keeps everything running in a continuous, harmonious circle of life. ~ Amy Leigh Mercree

I am not a climatologist, but I don't think any of the other witnesses are either. I do work in the related field of atomic, molecular and optical physics. I have spent my professional life studying the interactions of visible and infrared radiation with gases - one of the main physical phenomena behind the greenhouse effect. I have published over 200 papers in peer reviewed scientific journals. ~ William Happer

I am too good for philosophy and not good enough for physics. Mathematics is in between. ~ George Polya

In particular, if consciousness is an ontological fundamental-that is, a primary element of reality-then it may have the power to achieve what is both the best-documented and at the same time the spookiest effect of the m ind on the material world: the ability of consciousness to transform the infinite possibilities for, say, the position of a subatomic particle as described by quantum mechanics into the single reality for that position as detected by an observer. If that sounds both mysterious and spooky, it is a spookiness that has been a part of science since almost the beginning of the twentieth century. It was physics that first felt the breath of this ghost, with the discoveries of quantum mechanics, and it is in the field of neuroscience and the problem of mind and matter that its ethereal presence is felt most markedly today. ~ Jeffrey M. Schwartz

Unix is not so much a product as it is a painstakingly compiled oral history of the hacker subculture. It is our Gilgamesh epic: a living body of narrative that many people know by heart, and tell over and over again - making their own personal embellishments whenever it strikes their fancy. The bad embellishments are shouted down, the good ones picked up by others, polished, improved, and, over time, incorporated into the story. [ ... ] Thus Unix has slowly accreted around a simple kernel and acquired a kind of complexity and asymmetry about it that is organic, like the roots of a tree, or the branchings of a coronary artery. Understanding it is more like anatomy than physics. ~ Neal Stephenson

The entire world is made up of only two things, energy and matter. In elementary physics we learn that neither matter nor energy (the only two realities known to man) can be created nor destroyed. Both matter and energy can be transformed, but neither can be destroyed. Life is energy, if it is anything. If neither energy nor matter can be destroyed, of course life cannot be destroyed. Life, like other forms of energy, may be passed through various processes of transition, or change, but it cannot be destroyed. Death is mere transition. If death is not mere change, or transition, then nothing comes after death except a long, eternal, peaceful sleep, and sleep is nothing to be feared. Thus you may wipe out, forever, the fear of Death. ~ Napoleon Hill

I was not an especially diligent student but nevertheless obtained a reasonable education in physics. ~ Robert Coleman Richardson

Thus it can be argued that quantum theory provides an opening for an idea of nature and of our role within it that is in general accord with certain religious concepts, but that, by contrast, is quite incompatible with the precepts of mechanistic deterministic classical physics. Thus the replacement of classical mechanics by quantum mechanics opens the door to religious possibilities that formerly were rationally excluded. ~ Paul Davies

Programming is a science dressed up as art, because most of us don't understand the physics of software and it's rarely, if ever, taught. The physics of software is not algorithms, data structures, languages, and abstractions. These are just tools we make, use, and throw away. The real physics of software is the physics of people. Specifically, it's about our limitations when it comes to complexity and our desire to work together to solve large problems in pieces. This is the science of programming: make building blocks that people can understand and use easily, and people will work together to solve the very largest problems. ~ Pieter Hintjens

Physics is not about having memorized all the answers, but rather about asking the right questions. For when the right question is posed of a phenomenon, either the answer becomes clear or at least a path to further and more fruitful questioning is revealed. ~ James Kakalios

Why is it so difficult for us to think in relative terms? Well, for the good reason that human nature loves absoluteness, and erroneously considers it as a state of higher knowledge. ~ Felix Alba-Juez

It is an odd fact of evolution that we are the only species on Earth capable of creating science and philosophy. There easily could have been another species with some scientific talent, say that of the average human ten-year-old, but not as much as adult humans have; or one that is better than us at physics but worse at biology; or one that is better than us at everything. If there were such creatures all around us, I think we would be more willing to concede that human scientific intelligence might be limited in certain respects. ~ Colin McGinn

The myth of quantum consciousness sits well with many whose egos have made it impossible for them to accept the insignificant place science perceives for humanity, as modern instruments probe the farthest reaches of space and time. ... quantum consciousness has about as much substance as the aether from which it is composed. Early in this century, quantum mechanics and Einstein's relativity destroyed the notion of a holistic universe that had seemed within the realm of possibility in the century just past. First, Einstein did away with the aether, shattering the doctrine that we all move about inside a universal, cosmic fluid whose excitations connect us simultaneously to one another and to the rest of the universe. Second, Einstein and other physicists proved that matter and light were composed of particles, wiping away the notion of universal continuity. Atomic theory and quantum mechanics demonstrated that everything, even space and time, exists in discrete bits – quanta. To turn this around and say that twentieth century physics initiated some new holistic view of the universe is a complete misrepresentation of what actually took place. ... The myth of quantum consciousness should take its place along with gods, unicorns, and dragons as yet another product of the fantasies of people unwilling to accept what science, reason, and their own eyes tell them about the world. ~ Victor J. Stenger

conformed to the principle of least action, a foundation of physics that holds that light or any object moving between two points should follow the easiest path.3 Planck's paper not only contributed to the development of relativity theory; it also helped to legitimize it among other physicists. ~ Walter Isaacson

Physical laws are ruled by logic, and are ungovernable: so when the die comes to rest on its edge, it owes neither apology nor account. ~ John Hadac

The day I went into physics class it was death. ~ Sylvia Plath

Other than the laws of physics, rules have never really worked out for me. ~ Craig Ferguson

If you want to succeed in the world, you don't have to be much cleverer than other people. You just have to be one day earlier. ~ Leo Szilard

In literature classes, you don't learn about genes; in physics classes you don't learn about human evolution. So you get a fragmented view of the world. That makes it hard to find meaning in education. ~ David Christian

One of the greatest gifts that God has given us is free will. Even though it's free, we don't take advantage of it as much as we could when it comes to matters of the heart. ~ Niecy Nash

Whether looked at from outside or inside, bodies dissolve, matter vanishes, spirit remains - once we bother to go into the matter. "Spirit is the living body seen from within, and the body is the outer manifestation of the living spirit." Extend this statement by Carl Jung to all bodies from electrons to galaxies, and you have the ultimate physics ~ Douglas Harding

We'd already talked in the stacks, and I knew you were different from any other girl I'd met. And you told me that your parents were dead, and I thought that you were so ... lost and vulnerable. So when I saw you in the physics lab ... and I saw you try and take care of someone that you thought who had been through what you'd been through; could be that ... well, generous, and thoughtfull ... " Guy said.
"But you hardly knew me." said Willow
"I know ... I didn't know that we'd even talk again, or that if we did, if we'd get along, or maybe you were seeing someone else ... I just knew that the way you tried to protect someone's life that, especially given your situation ... I just ... I though that you had to be the most special girl I would ever meet ... ~ Julia Hoban

The test of science is not whether you are reasonable - there would not be much of physics if that was the case - the test is whether it works. And the great point about Newton's theory of gravitation was that it worked, that you could actually say something about the motion of the moon without knowing very much about the constitution of the Earth. ~ Hermann Bondi

Physics is not about how the world is, it is about what we can say about the world ~ Niels Bohr

Let us say, in a word, that the correlation between the laws of mathematics and of physics is the evidence of the rational character of nature. Nature may be reduced to motions; and motions can be understood only as force, activity. But the laws which connect motions are fundamentally mathematical laws,- laws of reason. Hence force, activity, can be understood only as rational, as spiritual. Nature is thus seen to mean Activity, and Activity is seen to mean Intelligence ~ John Dewey

It is odd, but on the infrequent occasions when I have been called upon in a formal place to play the bongo drums, the introducer never seems to find it necessary to mention that I also do theoretical physics. ~ Richard P. Feynman

All integral laws of spectral lines and of atomic theory spring originally from the quantum theory. It is the mysterious organon on which Nature plays her music of the spectra, and according to the rhythm of which she regulates the structure of the atoms and nuclei. ~ Arnold Sommerfeld

Arthur Compton became my graduate advisor. He was the ideal graduate advisor for me: he came into my research room only once during my graduate career and usually had no idea how I was spending my time. ~ Luis W. Alvarez

If you were standing in the path of the beam, you would obviously die pretty quickly. You wouldn't really die of anything, in the traditional sense. You would just stop being biology and start being physics. ~ Randall Munroe

We were making the first step out of the age of chemistry and physics, and into the age of biology. ~ Jeremy Rifkin
