Physics Quote by Edward Witten

Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. String theory does so again because a point…

— Edward Witten

“The uncertainty principle “protects” quantum mechanics. Heisenberg recognized that if it were possible to measure the momentum and the position simultaneously with a greater…

— Richard P. Feynman

Quantum physics is one of the hardest things to understand intuitively, because essentially the whole point is that our classical picture is wrong,

— Neil Turok

Anyone who can contemplate quantum mechanics without getting dizzy hasn't understood it.

— Niels Bohr

“Quantum physics shows that it is in the nature of reality to be unpredictable.”

— David Christian

Anyone not shocked by quantum mechanics has not yet understood it.

— Niels Bohr

The quantum entered physics with a jolt. It didn't fit anywhere; it made no sense; it contradicted everything we thought we knew about nature.…

— David C. Cassidy

There are a lot of mysteries about quantum mechanics, but they mostly arise in very detailed measurements in controlled settings.

— Lisa Randall

“Newton's equations of absolute exactitude and certainty ("classical determinism") were replaced by Schrodinger's new equations and Heisenberg's mathematics of fuzziness, indeterminacy, and probability.”

— Leon M. Lederman

Quantum mechanics broke the mold of the previous framework, classical mechanics, by establishing that the predictions of science are necessarily probabilistic.

— Brian Greene

“In a single century, quantum physics performed an extraordinary inversion. Uncertainty, once the enemy of the knowledge, became the engine of creation. Superposition transformed…

— Ph.D Ludmila Morozova-Buss

Quantum mechanics is so counter-intuitive, physicists have never been able to come up with a comfortable picture of how it works.
