Physics Quotes
-
It is going to be necessary that everything that happens in a finite volume of space and time would have to be analyzable with a finite number of logical operations. The present theory of physics is not that way, apparently. It allows space to go down into infinitesimal distances, wavelengths to get infinitely great, terms to be summed in infinite order, and so forth; and therefore, if this proposition that physics is computer-simulatable is right, physical law is wrong.
Richard Feynman

Every student of physics knows the axiom 'nature abhors a vacuum.' A little known corollary is that 'rowing coaches detest sending their crews in early.' Coaches will always find something to fill the end-of-practice vacuum.

It is shameful that there are so few women in science. In China there are many, many women in physics. There is a misconception in America that women scientists are all dowdy spinsters. This is the fault of men. In Chinese society, a woman is valued for what she is, and men encourage her to accomplishments yet she remains eternally feminine.
Chien-Shiung Wu

We could tell them alien civilization things that we have discovered in the realm of mathematical physics, but there is stuff that I would like to know. There are some famous problems like how to bring gravitation and quantum physics together, the long-sought-after theory of quantum gravity. But it may be hard to understand the answer that comes back.
Paul Davies
-
Theorists of journalism have long noted parallels to Heisenberg's uncertainty principle in physics: by reporting on something, one subtly but irrevocably changes it.
Ben Yagoda
-
There's been a greater awareness among people, especially geeks, that the laws of physics don't allow that much wiggle room in terms of things like faster-than-light travel, time travel, sending people to other planets. It's harder than we were aware a few decades ago. I think there used to be this widespread imagination, this idea that we'd eventually just hop in a rocket and go to Mars.
Charlie Jane Anders

What appear to be the most valuable aspects of the theoretical physics we have are the mathematical descriptions which enable us to predict events. These equations are, we would argue, the only realities we can be certain of in physics; any other ways we have of thinking about the situation are visual aids or mnemonics which make it easier for beings with our sort of macroscopic experience to use and remember the equations.

If you assume continuity, you can open the well-stocked mathematical toolkit of continuous functions and differential equations, the saws and hammers of engineering and physics for the past two centuries (and the foreseeable future).
Benoit Mandelbrot
-
There can be no final truth in ethics any more than in physics, until the last man has had his experience and said his say.
William James
-
Think of color, pitch, loudness, heaviness, and hotness. Each is the topic of a branch of physics
Benoit Mandelbrot
-
The world of physics is essentially the real world construed by mathematical abstractions, and the world of sense is the real world construed by the abstractions which the sense-organs immediately furnish. To suppose that the "material mode" is a primitive and groping attempt at physical conception is a fatal error in epistemology.
Susanne Langer

The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific "truth." But what is the source of knowledge? Where do the laws that are to be tested come from? Experiment, itself, helps to produce these laws, in the sense that it gives us hints. But also needed is imagination to create from these hints the great generalizations--to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess.
Richard Feynman
-
In its efforts to learn as much as possible about nature, modern physics has found that certain things can never be "known" with certainty. Much of our knowledge must always remain uncertain. The most we can know is in terms of probabilities.
Richard Feynman
-
This is absolutely correct and forms part of the larger concept that top-down causation is a key factor not just in the way the brain works but in broader contexts in biology and even physics.
George F. R. Ellis
-
The primary consequence of the computational nature of the universe is that the universe naturally generates complex systems, such as life. Although the basic laws of physics are comparatively simple in form, they give rise, because they are computationally universal, to systems of enormous complexity.
Seth Lloyd
-
I was a senior research scientist that changed the accepted view of the structure of the universe.I disproved one of the then widely accepted “laws” of physics, 'the conversation of parity', by proving that identical nuclear particles do not always act alike.
Chien-Shiung Wu
-
The beginning of the twentieth century witnessed the breakdown of the mechanistic theory even within physics, the science where it was the most successful... Relativity took over in field physics, and the science of quantum theory in microphysics... In view of parallel developments in physics, chemistry, biology, sociology, and economics, many branches of the contemporary sciences became... ‘sciences of organized complexity’ — that is, systems sciences.
Ervin Laszlo

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.
