Physics Quotes - Page 4

Wolfgang Pauli, in the months before Heisenberg's paper on matrix mechanics pointed the way to a new quantum theory, wrote to a friend, "At the moment physics is again terribly confused. In any case, it is too difficult for me, and I wish I had been a movie comedian or something of the sort and had never heard of physics." That testimony is particularly impressive if contrasted with Pauli's words less than five months later: "Heisenberg's type of mechanics has again given me hope and joy in life. To be sure it does not supply the solution to the riddle, but I believe it is again possible to march forward.

Wolfgang Pauli

It was like bouncing tennis balls off a mystery piece of furniture and deducing, from the direction in which the balls ricocheted, whether it was a chair or a table or a Welsh dresser.

Marcus Chown

There is something lamentable, degrading, and almost insane in pursuing the visionary schemes of past ages with dogged determination, in paths of learning which have been investigated by superior minds, and with which such adventurous persons are totally unacquainted. The history of Perpetual Motion is a history of the fool-hardiness of either half-learned, or totally ignorant persons.

Henry Dircks

Heisenberg's uncertainty relation measures the amount by which the complementary descriptions of the electron, or other fundamental entities, overlap. Position is very much a particle property - particles can be located precisely. Waves, on the other hand, have no precise location, but they do have momentum. The more you know about the wave aspect of reality, the less you know about the particle, and vice versa. Experiments designed to detect particles always detect particles; experiments designed to detect waves always detect waves. No experiment shows the electron behaving like a wave and a particle at the same time.

John Gribbin

The unsolved problems of the physical world now seem even more formidable than those solved in the twentieth century. Though in application it works splendidly, we do not even understand the physical meaning of quantum mechanics, much less how it might be united with general relativity.We don't know why the dimensionless constants (ratios of masses of elementary particles, ratios of strength of gravitational to electric forces, fine structure constant, etc.) have the values they do, unless we appeal to the implausible anthropic principle, which seems like a regression to Aristotelian teleology.

Gerald Holton

The power of the deductive network produced in physics has been illustrated in a delightful article by Victor F. Weisskopf. He begins by taking the magnitudes of six physical constants known by measurement: the mass of the proton, the mass and electric charge of the electron, the light velocity, Newton's gravitational constant, and the quantum of action of Planck. He adds three of four fundamental laws (e.g., de Broglie's relations connecting particle momentum and particle energy with the wavelength and frequency, and the Pauli exclusion principle), and shows that one can then derive a host of different, apparently quite unconnected, facts that happen to be known to us by observation separately ....

George Malcolm: half white, half black, with messy tousled hair, rumpled and tugged between kind of curly and extremely curly. Once, a year or so before, he'd been at our house and he'd pulled out a lock of his hair and used it to teach me about eddies and helixes. It's a circular current into a central station, he'd explained, giving me one to hold. I pulled on the spring. Nature is full of the same shapes, he said, taking me to the bathroom sink and spinning on the top and pointing out the way the water swirled down the drain. Taking me to the bookshelf and flipping open a book on weather and showing me a cyclone. Then a spiral galaxy. Pulling me back to the bathroom sink, to my glass jar of collected seashells, and pointing out the same curl in a miniature conch. See? he said, holding the seashell up to his hair. Yes! I clapped. His eyes were warm with teaching pleasure. It's galactic hair, he said, smiling.At school, George was legendary already. He was so natural at physics that one afternoon the eighth-grade science teacher had asked him to do a preview of the basics of relativity, really fast, for the class. George had stood up and done such a fine job, using a paperweight and a yardstick and the standard-issue school clock, that the teacher had pulled a twenty-dollar bill from his wallet. I'd like to be the first person to pay you for your clarity of mind, the teacher had said. George used the cash to order pizza for the class. Double pepperoni, he told me later, when I'd asked.

Aimee Bender

Highly complex numbers like the Comma of Pythagoras, Pi and Phi (sometimes called the Golden Proportion), are known as irrational numbers. They lie deep in the structure of the physical universe, and were seen by the Egyptians as the principles controlling creation, the principles by which matter is precipitated from the cosmic mind.Today scientists recognize the Comma of Pythagoras, Pi and the Golden Proportion as well as the closely related Fibonacci sequence are universal constants that describe complex patterns in astronomy, music and physics. ...To the Egyptians these numbers were also the secret harmonies of the cosmos and they incorporated them as rhythms and proportions in the construction of their pyramids and temples.

Jonathan Black

Since ancient times artists and architects have seen in the golden mean the most aesthetically satisfying geometric ratio.

Stephen M. Barr

The prime number 137 had continuously occupied Pauli's mind. It is an approximate value for a constant appearing in the fine structure theory of atomic spectra which in its theoretical expression ties together electromagnetism, relativity and quantum theory. Pauli saw the fine structure theory of spectra as a key in understanding the deepest contemporary problems of theoretical physics. For that reason the number 137 possessed a mysterious attraction for him.

K. V. Laurikainen

Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness.

Bill Bryson

The release of atomic power has changed everything except our way of thinking ... the solution to this problem lies in the heart of mankind. If only I had known, I should have become a watchmaker. (1945)

Albert Einstein

How wonderful that we have met with a paradox. Now we have some hope of making progress.

Niels Bohr

Quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables.

Werner Heisenberg

Time and space are finite in extent, but they don't have any boundary or edge. They would be like the surface of the earth, but with two more dimensions.

Stephen Hawking

God abhors a naked singularity.

Stephen Hawking

Let's grant that the stars are scattered through space, hither and yon. But how hither, and how yon? To the unaided eye the brightest stars are more than a hundred times brighter than the dimmest. So the dim ones are obviously a hundred times farther away from Earth, aren't they?Nope.That simple argument boldly assumes that all stars are intrinsically equally luminous, automatically making the near ones brighter than the far ones. Stars, however, come in a staggering range of luminosities, spanning ten orders of magnitude ten powers of ten. So the brightest stars are not necessarily the ones closest to Earth. In fact, most of the stars you see in the night sky are of the highly luminous variety, and they lie extraordinarily far away.If most of the stars we see are highly luminous, then surely those stars are common throughout the galaxy.Nope again.High-luminosity stars are the rarest. In any given volume of space, they're outnumbered by the low-luminosity stars a thousand to one. It's the prodigious energy output of high-luminosity stars that enables you to see them across such large volumes of space.

Neil deGrasse Tyson

Physicists like to think that all you have to do is say, these are the conditions, now what happens next?

Richard Feynman

A relativist is an individual who doesn't know the difference between an adjective and an adverb.

Bill Gaede

...rather than ask why something happened (i.e. what caused it), Jung asked: What did it happen for? This same tendency appears in physics: Many modern physicists are now looking more for "connections" in nature than for causal laws (determinism).

M.L. von Franz

I recently forced myself to read a book on quantum physics, just to try and learn something new. I was confused by the middle of the first sentence and it all went downhill from there. The only thing I can remember learning is that a parallel universe can theoretically be contained on the head of a needle. I don't really know what that means, but I am now more careful handling needles.

Stephan Pastis

A mathematician is a magician who converts adjectives into nouns: continuous into continuum, infinite into infinity, infinitesimal into location, 0D into point, 1D into line, curved into geodesic...

Bill Gaede

Some string theorists prefer to believe that string theory is too arcane to be understood by human beings, rather than consider the possibility that it might just be wrong.

Lee Smolin

Privacy, in fact, was almost as desirable for physics as it was for sex.

Ursula K Le Guin

Three quarks for Muster Mark!

James Joyce

The simple process of eating and breathing weave all of us together into a vast four-dimensional array. No matter how isolated you may sometimes feel, no matter how lonely, you are never really cut off from the whole.

Rudy Rucker

Give me a place to stand, a lever long enough and a fulcrum. and I can move the Earth

Archimedes

Objects moving in a circle are under the influence of changing force.

Melody Mayer

Physics depends on a universe infinitely centred on an equals sign.

Mark Z. Danielewski

Ideas that require people to reorganize their picture of the world provoke hostility.

James Gleick

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

The fireworks went on for nearly half an hour, great pulsing strobes, fiery dandelions and starbursts of light brightening both sky and water. It was hard to tell which was reality and which was reflection, as if there were two displays, above and below, going on simultaneously—one in space-time, mused Max, and the other in time-space.

Sol Luckman

Here at great expense,' [Colonel Groves] moaned to Oppenheimer, 'the government has assembled the world's largest collection of crackpots.

Steve Sheinkin

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.

Edward Witten

[Concerning] phosphorescent bodies, and in particular to uranium salts whose phosphorescence has a very brief duration. With the double sulfate of uranium and potassium ... I was able to perform the following experiment: One wraps a Lumière photographic plate with a bromide emulsion in two sheets of very thick black paper, such that the plate does not become clouded upon being exposed to the sun for a day. One places on the sheet of paper, on the outside, a slab of the phosphorescent substance, and one exposes the whole to the sun for several hours. When one then develops the photographic plate, one recognizes that the silhouette of the phosphorescent substance appears in black on the negative. If one places between the phosphorescent substance and the paper a piece of money or a metal screen pierced with a cut-out design, one sees the image of these objects appear on the negative. One can repeat the same experiments placing a thin pane of glass between the phosphorescent substance and the paper, which excludes the possibility of chemical action due to vapors which might emanate from the substance when heated by the sun's rays. One must conclude from these experiments that the phosphorescent substance in question emits rays which pass through the opaque paper and reduces silver

Henri Becquerel

Ronan didn't need physics. He could intimidate even a piece of plywood into doing what he wanted.

For the moment we might very well can them DUNNOS (for Dark Unknown Nonreflective Nondetectable Objects Somewhere).

Bill Bryson

Time and space were, from Death's point of view, merely things that he'd heard described. When it came to Death, they ticked the box marked Not Applicable. It might help to think of the universe as a rubber sheet, or perhaps not.

Terry Pratchett

One may characterize physics as the doctrine of the repeatable, be it a succession in time or the co-existence in space. The validity of physical theorems is founded on this repeatability.

Friedrich Hund

From a philosophical point of view, Leibniz's most interesting argument was that absolute space conflicted with what he called the principle of the identity of indiscernibles (PII). PII says that if two objects are indiscernible, then they are identical, i.e. they are really one and the same object. What does it mean to call two objects indiscernible? It means that no difference at all can be found between them--they have exactly the same attributes. So if PII is true, then any two genuinely distinct objects must differ in at least one of their attributes--otherwise they would be one, not two. PII is intuitively quite compelling. It certainly is not easy to find an example of two distinct objects that share all their attributes. Even two mass-produced factory goods will normally differ in innumerable ways, even if the differences cannot be detected with the naked eye.Leibniz asks us to imagine two different universes, both containing exactly the same objects. In Universe One, each object occupies a particular location in absolute space.In Universe Two, each object has been shifted to a different location in absolute space, two miles to the east (for example). There would be no way of telling these two universes apart. For we cannot observe the position of an object in absolute space, as Newton himself admitted. All we can observe are the positions of objects relative to each other, and these would remain unchanged--for all objects are shifted by the same amount. No observations or experiments could ever reveal whether we lived in universe One or Two.

Samir Okasha

The claim that the universe *began* with the big bang has no basis in current physical and cosmological knowledge. The observations confirming the big bang do not rule out the possibility of a prior universe.

Victor J. Stenger

Mars One has the power to show people around the globe what is possible if we just all work on one goal. No human has left Earth’s orbit since 1972 and no one ever ploughed beyond the moon into deep space. It’s finally time to inspire the world and make the next giant leap for mankind.

Nico Marquardt

In the vestibule of the Manchester Town Hall are placed two life-sized marble statues facing each other. One of these is that of John Dalton ... the other that of James Prescott Joule. ... Thus the honour is done to Manchester's two greatest sons—to Dalton, the founder of modern Chemistry and of the atomic theory, and the laws of chemical-combining proportions; to Joule, the founder of modern physics and the discoverer of the Law of Conservation of Energy.One gave to the world the final proof ... that in every kind of chemical change no loss of matter occurs; the other proved that in all the varied modes of physical change, no loss of energy takes place.

Henry Enfield Roscoe

Being an investment banker is pretty much the perfect job for an all around triple-threat genius, and because I’m doing so well with it, I know I’m actually smarter than certifiable geniuses like Stephen Hawking and Einstein.

A.D. Aliwat

I believe that this Nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to earth.

John F Kennedy

Time becomes meaningless without memory.

Jon Edgell

Then there are those who think their bodies don't exist. They live by mechanical time. They rise at seven o'clock in the morning. They eat their lunch at noon and their supper at six. They arrive at their appointments on time, precisely by the clock. They make love between eight and ten at night. They work forty hours a week, read the Sunday paper on Sunday, play chess on Tuesday nights. When their stomach growls, they look at their watch to see if it is time to eat. When they begin to lose themselves in a concert, they look at the clock above the stage to see when it will be time to go home. They know that the body is not a thing of wild magic, but a collection of chemicals, tissues, and nerve impulses. Thoughts are no more than electrical surges in the brain. Sexual arousal is no more than a flow of chemicals to certain nerve endings. Sadness no more than a bit of acid transfixed in the cerebellum. In short, the body is a machine, subject to the same laws of electricity and mechanics as an electron or clock. As such, the body must be addressed in the language of physics. And if the body speaks, it is the speaking only of so many levers and forces. The body is a thing to be ordered, not obeyed.

Alan Lightman

...Why is it, that from the moment you enter medical school to the moment you retire, that the only disorder you will ever diagnosis with a physics book - is obesity? This is biology folks, it's endocrinology, it's physiology - physics has nothing to do with it. The law of thermodynamics is always true, [but] the energy balance equation is irrelevant...

Gary Taubes

You may not feel outstandingly robust, but if you are an average-sized adult you will contain within your modest frame no less than 7 X 10^18 joules of potential energy—enough to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point.

Bill Bryson

The more we delve into quantum mechanics the stranger the world becomes; appreciating this strangeness of the world, whilst still operating in that which you now consider reality, will be the foundation for shifting the current trajectory of your life from ordinary to extraordinary.

Kevin Michel

The particles that are the very building blocks of all things, are in all possible locations until observation/measurement causes them to choose a specific position.

Kevin Michel

Today most scientists would agree with the ancient Hindus that nothing exists or is destroyed, things merely change shape or form…the cosmic radiation that is thought to come from the explosion of creation strikes the earth with equal intensity from all directions, which suggests either that the earth is at the center of the universe, as in our innocence we once supposed, or that the known universe has no center.

Peter Matthiessen

We must realize that growth is but an adolescent phase of life which stops when physical maturity is reached. If growth continues in the period of maturity it is called obesity or cancer. Prescribing growth as the cure for the energy crisis has all the logic of prescribing increasing quantities of food as a remedy for obesity.

Albert A. Bartlett

There was no room for dust devils in the laws of physics, as least in the rigid form in which they were usually taught. There is a kind of unspoken collusion going on in mainstream science education: you get your competent but bored, insecure and hence stodgy teacher talking to an audience divided between engineering students, who are going to be responsible for making bridges that won’t fall down or airplanes that won’t suddenly plunge vertically into the ground at six hundred miles an hour, and who by definition get sweaty palms and vindictive attitudes when their teacher suddenly veers off track and begins raving about wild and completely nonintuitive phenomena; and physics students, who derive much of their self-esteem from knowing that they are smarter and morally purer than the engineering students, and who by definition don’t want to hear about anything that makes no fucking sense. This collusion results in the professor saying: (something along the lines of) dust is heavier than air, therefore it falls until it hits the ground. That’s all there is to know about dust. The engineers love it because they like their issues dead and crucified like butterflies under glass. The physicists love it because they want to think they understand everything. No one asks difficult questions. And outside the windows, the dust devils continue to gambol across the campus.

Neal Stephenson

Interestingly enough, whenever I cite examples from superhero comic books in a lecture, my students never wonder when they will use this information in their "real life". Apparently they all have plans, post-graduation, that involve protecting the City from all threat while wearing spandex. As a law-abiding citizen, this notion fills me with a great sense of security, knowing as I do how many of my scientist colleagues could charitably be termed "mad".

James Kakalios

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.

As was the case for Nobel's own invention of dynamite, the uses that are made of increased knowledge can serve both beneficial and potentially harmful ends. Increased knowledge clearly implies increased responsibility.
