Quotes About Physics

It seems that every practitioner of physics has had to wonder at some point why mathematics and physics have come to be so closely entwined. Opinions vary on the answer. ..Bertrand Russell acknowledged..'Physics is mathematical not because we know so much about the physical world, but because we know so little.' ..Mathematics may be indispensable to physics, but it obviously does not constitute physics.

I spent eighteen months as a graduate student in physics at Columbia University, waiting unhappily for an opportunity to work in a laboratory and wondering if I should continue in physics.

A sound Physics of the Earth should include all the primary considerations of the earth's atmosphere, of the characteristics and continual changes of the earth's external crust, and finally of the origin and development of living organisms. These considerations naturally divide the physics of the earth into three essential parts, the first being a theory of the atmosphere, or Meteorology, the second, a theory of the earth's external crust, or Hydrogeology, and the third, a theory of living organisms, or Biology.

It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we say about nature.

Science may explain the world, but we still have to explain science. The laws which enable the universe to come into being spontaneously seem themselves to be the product of exceedingly ingenious design. If physics is the product of design, the universe must have a purpose, and the evidence of modern physics suggests strongly to me that the purpose includes us

When asked ... [about] an underlying quantum world, Bohr would answer, 'There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about Nature.'

The violent reaction on the recent development of modern physics can only be understood when one realises that here the foundations of physics have started moving; and that this motion has caused the feeling that the ground would be cut from science

When I was in high school, I was in a special math class. I was infatuated with physics, particularly nuclear physics, Einstein, and the Big Bang. I read a lot about black holes. And partly because I'm so lazy I thought you could do all this just by looking at the sky and thinking up universes. It didn't seem like hard work when I was a kid, so I enrolled in this class.

We have a closed circle of consistency here: the laws of physics produce complex systems, and these complex systems lead to consciousness, which then produces mathematics, which can then encode in a succinct and inspiring way the very underlying laws of physics that gave rise to it.

That is, you can have nothingness, absolute nothingness for maybe a tiny fraction of a second, if a second can be defined in that arena, but then it falls apart into a something and an anti-something. And that something is then what we call the universe. But can we really understand that or put rigorous mathematics or testable experiments against that? Not yet. So one of the big holy grail of physics is to understand why there is something rather than nothing.

It is difficult to make good scalable use of a CPU like you can of a graphics card. You certainly don't want 'better or worse' physics or AI in your game

In 1947 I defended my thesis on nuclear physics, and in 1948 I was included in a group of research scientists whose task was to develop nuclear weapons.

You will certainly not doubt the necessity of studying astronomy and physics, if you are desirous of comprehending the relation between the world and Providence as it is in reality, and not according to imagination.

Computer science is not as old as physics; it lags by a couple of hundred years. However, this does not mean that there is significantly less on the computer scientist's plate than on the physicist's: younger it may be, but it has had a far more intense upbringing!

Modern physics had shown that the rhythm of creation and destruction is not only manifest in the turn of the seasons and in the birth and death of living creatures, but is also the very essence of inorganic matter. For modern physicists...Shiva's dance is the dance of subatomic matter.

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

Don't be surprised if in the 21st century lectures on meditation appear in university catalogues for physics.

Now, learning how to make a movie is something you can figure out in about an afternoon. The physics of it, the marks, the lights, etc. What's hard to do is to suspend your own feelings of self consciousness. The natural actors can do that; they can become part of a characterization and learn how to maintain it.

I've always liked all the sciences like math, physics and biology

From the point of view of physics, it is a miracle that [seven million New Yorkers are fed each day] without any control mechanism other than sheer capitalism.

Biology is now bigger than physics, as measured by the size of budgets, by the size of the workforce, or by the output of major discoveries; and biology is likely to remain the biggest part of science through the twenty-first century.

Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent.

I love to try to understand first principles and be guided by that. But then, enrich them, because they won't last forever, just like everybody thought Newton had all the answers. And you probably read that, in the last of the 19th century, Harvard and others were discouraging people from going into physics because we have all the answers. And right after that, of course - we have - all this stuff is thrown out the window. And now we have whole new answers.

Now that physics is proving the intelligence of the universe what are we to do about the stupidity of mankind? I include myself. I know that the earth is not flat but my feet are. I know that space is curved but my brain has been condoned by habit to grow in a straight line. What I call light is my own blend of darkness. What I call a view is my hand-painted trompe-l'oeil. I run after knowledge like a ferret down a ferret hole. My limitations, I call the boundaries of what can be known. I interpret the world by confusing other people's psychology with my own.

We live in the hope and faith that, by the advance of molecular physics, we shall by-and-by be able to see our way as clearly from the constituents of water to the properties of water, as we are now able to deduce the operations of a watch from the form of its parts and the manner in which they are put together.

My father was on the faculty in the Chemistry Department of Harvard University; my mother had one year of graduate work in physics before her marriage.

Government is like physics, you know - for every action, there's a reaction.

After the conversations about Indian philosophy, some of the ideas of Quantum Physics that had seemed so crazy suddenly made much more sense.

Whether you function as welders or inspectors, the laws of physics are implacable lie-detectors. You may fool men. You will never fool the metal.

The science behind Interstellar is interesting, because some of it is absolutely real astrophysics and orbital mechanics, some of it is theoretical physics, and some of it is completely Hollywood. When a science fiction movie is based on plausible science, it's really good.

In our work, we are always between Scylla and Charybdis; we may fail to abstract enough, and miss important physics, or we may abstract too much and end up with fictitious objects in our models turning into real monsters that devour us.

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

I am fascinated by quantum physics.

I vowed to myself that when I grew up and became a theoretical physicist, in addition to doing research, I would write books that I would have liked to have read as a child. So whenever I write, I imagine myself, as a youth, reading my books, being thrilled by the incredible advances being made in physics and science.

Science works because the phenomenon being described can be relied on to remain the same. Even in quantum physics, where phenomena are changed by observation, the way in which observation interferes is regular and falls within a limited range of possibilities. Human culture, however, has the nasty habit of never staying the same for very long.

The observer, when he seems to himself to be observing a stone, is really, if physics is to be believed, observing the effects of the stone upon himself.

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.

If the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics.

I am now convinced that theoretical physics is actually philosophy.

I grew up wanting to be a musician, but my parents were sure I would starve to death. So, they put me in physics and chemistry. That eventually blew up, and I got into radio.

While there is such a thing as correctness in ethics, in interpretation, in mathematics, the way to understand that is not by trying to model it on the ways in which we get things right in physics.

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.

It is important to realize that in physics today, we have no knowledge of what energy is

Why can't parents dance? Is it some universal law of physics or something?

Good applied science in medicine, as in physics, requires a high degree of certainty about the basic facts at hand, and especially about their meaning, and we have not yet reached this point for most of medicine.

Quantum physics is no longer an abstract theory for specialists. We must now absolutely include it in our education and also in our culture.

Science itself is badly in need of integration and unification. The tendency is more and more the other way ... Only the graduate student, poor beast of burden that he is, can be expected to know a little of each. As the number of physicists increases, each specialty becomes more self-sustaining and self-contained. Such Balkanization carries physics, and indeed, every science further away, from natural philosophy, which, intellectually, is the meaning and goal of science.

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.
