Physics Quotes
-
Theoretical physics hardly requires any research funding, so I never felt the need. The overall government and institutional support has been good enough for my work.
Ashoke Sen
-
In physics the truth is rarely perfectly clear, and that is certainly universally the case in human affairs. Hence, what is not surrounded by uncertainty cannot be the truth.
Richard Feynman
-
There are very few things that can be proved rigorously in condensed matter physics.
Anthony James Leggett
-
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
-
Instead of physicists teaching physics, physicists should go home and see what physics applies to their home.
Bill Mollison
-
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
-
Under the roof of one controversial assumption about physics, we discuss five big questions that can be addressed using concepts from a modern understanding of digital informational processes. The assumption is called finite nature. The digital mechanics model is obtained by applying the assumption to physics. The questions are as follows: 1. What is the origin of spin? 2. Why are there symmetries and CPT (charge conjugation, parity, and time reversal)? 3. What is the origin of length? 4. What does a process model of motion tell us? 5. Can the finite nature assumption account for the efficacy of quantum mechanics?
Edward Fredkin
-
Classical physics has been superseded by quantum theory: quantum theory is verified by experiments. Experiments must be described in terms of classical physics.
Carl Friedrich von Weizsacker
-
The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve.
Eugene Wigner
-
[There are, in us] possibilities that take our breath away, and show a world wider than either physics or philistine ethics can imagine. Here is a world in which all is well, in spite of certain forms of death, death of hope, death of strength, death of responsibility, of fear and wrong, death of everything that paganism, naturalism and legalism pin their trust on.
William James
-
Physics is very muddled again at the moment; it is much too hard for me anyway, and I wish I were a movie comedian or something like that and had never heard anything about physics!
Wolfgang Pauli
-
Einstein and the Quantum is delightful to read, with numerous historical details that were new to me and cham1ing vignettes of Einstein and his colleagues. By avoiding mathematics, Stone makes his book accessible to general readers, but even physicists who are well versed in Einstein and his physics are likely to find new insights into the most remarkable mind of the modern era.
