Physics Subject Quotes & Sayings

On the contrary, it's because somebody knows something about it that we can't talk about physics . It's the things that nobody knows anything about that we can discuss. We can talk about the weather; we can talk about social problems; we can talk about psychology; we can talk about international finance gold transfers we can't talk about, because those are understood so it's the subject that nobody knows anything about that we can all talk about! — Richard P. Feynman

Even as rigorous a determinist as Karl Marx, who at times described the social behaviour of the bourgeoisie in terms which suggested a problem in social physics, could subject it at other times to a withering scorn which only the presupposition of moral responsibility could justify. — Reinhold Niebuhr

All rational knowledge is either material, and concerns some objects, or formal, and is occupied only with the form of understanding and reason itself and with the universal rules of thinking, without regard to distinctions among objects.
formal philosophy is called logic. Material philosophy, however, which has to do with definite object objects and the laws to which they are subject, is divided into two parts. This is because these laws are either laws of nature or laws of freedom. The science of the former is called physics, and that of the latter ethics. The former is also called theory of nature and the latter theory of morals. — Immanuel Kant

I suppose my interest in looking for life elsewhere in the universe really dates back to my teens. What teenager doesn't look up at the sky at night and think am I alone in the universe? Well most people get over it, but I never did and though I made a career more in physics and cosmology than astrobiology I've always had a soft spot for the subject of life because it does seem so mysterious. — Paul Davies

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

Myth makes Echo the subject of longing and desire. Physics makes Echo the subject of distance and design. Where emotion and reason are concerned both claims are accurate. And where there is no Echo there is no description of space or love. There is only science. — Mark Z. Danielewski

Writing, I reminded them, can't be taught or learned in a vacuum. We must say to students in every area of knowledge: "This is how other people have written about this subject. Read it; study it; think about it. You can do it too." In many subjects, students don't even know that a literature exists - that mathematics, for instance, consists of more than right and wrong answers, that physics consists of more than right or wrong lab reports. I — William Zinsser

Physics has never been a comfortable subject for human psychology. The desire to regard everything outside the human race's purview as insignificant, and everything within that purview as firmly under the control of tribal myth and custom, is as strong today as it was in the time of Galileo. — Celia Green

The great problem of today is, how to subject all physical phenomena to dynamical laws. With all the experimental devices, and all the mathematical appliances of this generation, the human mind has been baffled in its attempts to construct a universal science of physics. — Joseph Lovering

Each of us is aware he's a material being, subject to the laws of physiology and physics, and that the strength of all our emotions combined cannot counteract those laws. It can only hate them. The eternal belief of lovers and poets in the power of love which is more enduring that death, the finis vitae sed non amoris that has pursued us through the centuries is a lie. But this lie is not ridiculous, it's simply futile. To be a clock on the other hand, measuring the passage of time, one that is smashed and rebuilt over and again, one in whose mechanism despair and love are set in motion by the watchmaker along with the first movements of the cogs. To know one is a repeater of suffering felt ever more deeply as it becomes increasingly comical through a multiple repetitions. To replay human existence - fine. But to replay it in the way a drunk replays a corny tune pushing coins over and over into the jukebox? — Stanislaw Lem

The main thesis of mind-physics holds that consciousness and matter are both manifestations of a more primary entity, and that the processes of manifestation exhibit equivalent invariances for both consciousness and matter. When the program for mind-physics is complete the subject-object dichotomy of modal logic, the polarity of concept-percept, and the antagonism between morality and technology will all come to an end. Then the non-repeatable experiment will be understood to be more primary than the traditional repeatable experiment. — Paul Laffoley

I try to show the public that chemistry, biology, physics, astrophysics is life. It is not some separate subject that you have to be pulled into a corner to be taught about. — Neil DeGrasse Tyson

I introduce the subject of fine structure with a mini-calendar of events. ...

Winter 1914-15. Sommerfeld computes relativistic orbits for hydrogen-like atoms. Pashcen, aware of these studies, carefully investigates fine structures, ....

January 6, 1916. Sommerfeld announces his fine structure formula, citing results to be published by Paschen in support of his answer.

February 1916. Einstein to Sommerfeld: "A revelation!"

March 1916. Bohr to Sommerfeld: "I do not believe ever to have read anything with more joy than your beautiful work."

September 1916. Paschen publishes his work, acknowledging Sommerfeld's "indefatigable efforts. — Abraham Pais

It's as if we think the laws of physics are subject to debate and amendment and political contributions can sway the laws of physics. — Al Gore

We may as well cut out group theory. That is a subject that will never be of any use in physics. — James Jeans

I am a successful lecturer in physics for popular audiences. The real entertainment gimmick is the excitement, drama and mystery of the subject matter. People love to learn something, they are 'entertained' enormously by being allowed to understand a little bit of something they never understood before. One must have faith in the subject and in people's interest in it. — Richard P. Feynman

Physics does not change the nature of the world it studies, and no science of behavior can change the essential nature of man, even though both sciences yield technologies with a vast power to manipulate the subject matters. — Pope Paul VI

It is more important to me that my students come out of my class believing 'This story is interesting and I might want to know more about it', than to fill them up with information. If I can remind them or convince them that history is interesting then I feel I have succeeded, because unlike chemistry or physics, history is a subject that anyone can teach themselves, if they are interested.[ — H.W. Brands

My idea of an educated person is one who can converse on one subject for more than two minutes. — Robert Andrews Millikan

Physics, owing to the simplicity of its subject matter, has reached a higher state of development than any other science. — Bertrand Russell

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

In a way, mathematics is the only infinite human activity. It is conceivable that humanity could eventually learn everything in physics or biology. But humanity certainly won't ever be able to find out everything in mathematics, because the subject is infinite. Numbers themselves are infinite. That's why mathematics is really my only interest. — Paul Erdos

Scientists - who prefer explanations subject to laboratory tests - figure that everything we see today was as inevitable as wrinkles, once the Big Bang established physics. Stars and planets were cooked up as huge clouds of matter collapsed and coalesced. — Seth Shostak

My latter schooldays and my university days were during the war, when science - physics, in particular - was a very important and glamorous subject. A lot of us felt that if we couldn't get into science, we might try engineering or medicine. — John Henry Carver

I am a particle physicist, which is the nearest branch to nuclear physics. So in that sense I was the sort of right connection with the subject of nuclear energy and so on. — Abdus Salam

Physical brains are subject to the laws of physics; mental states are subject to the laws of logic. Those who think mental states are entirely physical hold a logically contradictory position. In order to think rationally about their thoughts , they must have the freedom to do so, but this freedom is unavailable if the laws of physics and chemistry are controlling their thoughts. — J. Warner Wallace

My physics teacher, Thomas Miner was particularly gifted. To this day, I remember how he introduced the subject of physics. He told us we were going to learn how to deal with very simple questions such as how a body falls due to the acceleration of gravity. — Steven Chu

Although it is hard to visualize a landscape in a space of high dimensions, the more the number of parameters, the more likely it is that a walk of any finite distance, taken in a random direction from a place near the summit of a mountain, will go down rather than up. Thus, we may conclude that, if the hypotheses made here are true, most changes in the parameters of the laws of physics will decrease the rate at which black holes are produced in our universe. Because of this, the theory I am sketching here is actually subject to observational test. — Lee Smolin

Briefly stated, the Gell-Mann Amnesia effect is as follows. You open the newspaper to an article on some subject you know well. In Murray's case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so wrong it actually presents the story backward - reversing cause and effect. I call these the "wet streets cause rain" stories. Paper's full of them.
In any case, you read with exasperation or amusement the multiple errors in a story, and then turn the page to national or international affairs, and read as if the rest of the newspaper was somehow more accurate about Palestine than the baloney you just read. You turn the page, and forget what you know. — Michael Crichton

Economics is haunted by more fallacies than any other study known to man. This is no accident. The inherent difficulties of the subject would be great enough in any case, but they are multiplied a thousandfold by a factor that is insignificant in, say, physics, mathematics or medicine - the special pleading of selfish interests. — Henry Hazlitt

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

"I could use the fresh air. I think that put my brain to sleep."
She pointed at the text as if it was a piece of rotten meat.
"Physics?" I said. "You must need a more advanced text."
"No, it's just boring."
I picked the book up and double checked the title, to make sure I hadn't misidentified the subject.
"Boring?" I said. "How can physics be ... ?"
I looked up to see she'd already left the room. Simon pointed at the text, grinned and faked a yawn.
"Hold on," I said, striding after her. "Physics is not boring. Maybe you just need me to explain it better. Chloe? Chloe!" — Kelley Armstrong

The behavior of temperature and heat and so forth can certainly be understood in terms of atoms: That's the subject known as "statistical mechanics." But it can equally well be understood without knowing anything whatsoever about atoms: That's the phenomenological approach we've been discussing, known as "thermodynamics." It is a common occurrence in physics that in complex, macroscopic systems, regular patterns emerge dynamically from underlying microscopic rules. Despite the way it is sometimes portrayed, there is no competition between fundamental physics and the study of emergent phenomena; both are fascinating and crucially important to our understanding of nature. — Sean Carroll

Unfortunately, a lot of economists wanted to make their subject a science. So the more what you do resembles physics or chemistry, the more credible you become. — Ha-Joon Chang

It will reward enough for me if, by the publication of the present experiment, I have directed the attention of investigators to this subject, which still promises much for physical optics and appears to open a new field. — Joseph Von Fraunhofer

The scientific method," Thomas Henry Huxley once wrote, "is nothing but the normal working of the human mind." That is to say, when the mind is working; that is to say further, when it is engaged in corrrecting its mistakes.
Taking this point of view, we may conclude that science is not physics, biology, or chemistry
is not even a "subject"
but a moral imperative drawn from a larger narrative whose purpose is to give perspective, balance, and humility to learning. — Neil Postman

In microphysics the observer interferes with the experiment in a way that can't be measured and that therefore can't be eliminated. No natural laws can be formulated, saying "such-and-such will happen in every case." All the microphysicist can say is "such-and-such is, according to statistical probability, likely to happen." This naturally represents a tremendous problem for our classical physical thinking. It requires a consideration, in a scientific experiment, of the mental outlook of the participant-observer: It could this be said that scientists can no longer hope to describe any aspects or qualities of outer objects in a completely independent, "objective" manner. — M.L. Von Franz

As biological organisms made of matter, we are subject to the laws of physics and biology: as conscious persons who create our own history we are free to decide what that history shall be. Without science, we should have no notion of equality; without art, no notion of liberty. — W. H. Auden

At one point I wanted to work for NASA and be an astrophysicist, so I did physics, math, and chemistry before realizing I probably wasn't quite smart enough to do that. But I am still hugely interested in cosmology and astrophysics. That is my geeky subject area. — Gemma Chan

As Sommerfeld said in his famous text "Spectral Lines and Atomic Constitution," on which a generation of physicists learned the subject, "In the fine structure constant e is the representative of the electron theory, h the appropriate representative of the quantum theory, c comes from relativity and characterizes it in contrast to classical theory. — Emilio Segre

Primary causes are unknown to us; but are subject to simple and constant laws, which may be discovered by observation, the study of them being the object of natural philosophy.
Heat, like gravity, penetrates every substance of the universe, its rays occupy all parts of space. The object of our work is to set forth the mathematical laws which this element obeys. The theory of heat will hereafter form one of the most important branches of general physics. — Joseph Fourier

Debts are subject to the laws of mathematics rather than physics. Unlike wealth, which is subject to the laws of thermodynamics, debts do not rot with old age and are not consumed in the process of living. On the contrary, they grow at so much per cent per annum, by the well-known mathematical laws of simple and compound interest ... It is this underlying confusion between wealth and debt which has made such a tragedy of the scientific era. — Frederick Soddy

Computer science is to biology what calculus is to physics. It's the natural mathematical technique that best maps the character of the subject. — Harold Morowitz

The interaction between math and physics is a two-way process, with each of the two subjects drawing from and inspiring the other. At different times, one of them may take the lead in developing a particular idea, only to yield to the other subject as focus shifts. But altogether, the two interact in a virtuous circle of mutual influence. — Edward Frenkel

There was a Princess Somebody of Denmark sitting at a table with a number of people around her, and I saw an empty chair at their table and sat down.
She turned to me and said, "Oh! You're one of the Nobel-Prize-winners. In what field did you do your work?"
"In physics," I said.
"Oh. Well, nobody knows anything about that, so I guess we can't talk about it."
"On the contrary," I answered. "It's because somebody knows something about it that we can't talk about physics. It's the things that nobody knows anything about that we can discuss. We can talk about the weather; we can talk about social problems; we can talk about psychology; we can talk about international finance--gold transfers we can't talk about, because those are understood--so it's the subject that nobody knows anything about that we can all talk about!"
I don't know how they do it. There's a way of forming ice on the surface of the face, and she did it! — Richard Feynman

I do not think the division of the subject into two parts - into applied mathematics and experimental physics a good one, for natural philosophy without experiment is merely mathematical exercise, while experiment without mathematics will neither sufficiently discipline the mind or sufficiently extend our knowledge in a subject like physics. — Balfour Stewart

The belief in an external world independent of the perceiving subject is the basis of all natural science. Since, however, sense perception only gives information of this external world or of "physical reality" indirectly, we can only grasp the latter by speculative means. It follows from this that our notions of physical reality can never be final. We must always be ready to change these notions - that is to say, the axiomatic basis of physics - in order to do justice to perceived facts in the most perfect way. — Albert Einstein
