Physics Quotes
-
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

Have no respect whatsoever for authority; forget who said it and instead look what he starts with, where he ends up, and ask yourself, "Is it reasonable?"
Richard Feynman
-
It is to be emphasized that no matter how many amplitude arrows we draw, add, or multiply, our objective is to calculate a single final arrow for the event . Mistakes are often made by physics students at first because they do not keep this important point in mind. They work for so long analyzing events involving a single photon that they begin to think that the arrow is somehow associated with the photon rather than with the event.
Richard Feynman
-
I think that physics is about escaping the prison of the received thoughts and searching for novel ways of thinking the world, about trying to clear a bit the misty lake of insubstantial dreams, which reflect reality like the lake reflects the mountains.
Carlo Rovelli
-
Therefore psychologically we must keep all the theories in our heads, and every theoretical physicist who is any good knows six or seven different theoretical representations for exactly the same physics.
Richard Feynman
-
When I was a student, the laws of physics were regarded as completely off limits. The job of the scientist, we were told, is to discover the laws and apply them, not inquire into their provenance.
Paul Davies
-
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 Feynman
-
Thinking about quantum physics is like unraveling your brain and putting it back together again upside down. Much like studying Kabbalah.
Rebecca Pidgeon
-
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
-
I accept no principles of physics which are not also accepted in mathematics.
Rene Descartes
-
I went to Princeton specifically to study physics.
Jeff Bezos
-
I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possibly avoid it, 'But how can it be like that?' ...Nobody knows how it can be like that.
Richard Feynman
-
All theoretical chemistry is really physics; and all theoretical chemists know it.
Richard Feynman
-
Apparently there is a great discovery or insight which our culture is deliberately designed to suppress, distort, and ignore. That is that nature is some kind of minded entity. That nature is not simply the random flight of atoms through electromagnetic fields. Nature is not the empty, despiritualized , lumpen matter that we inherit from modern physics. But it is instead a kind of intelligence, a kind of mind.
Terence McKenna
