Doubt Quote by Weike Wang

“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

“Heisenberg's uncertainty relation measures the amount by which the complementary descriptions of the electron, or other fundamental entities, overlap. Position is very much a…

— John Gribbin

The uncertainty principle refers to the degree of indeterminateness in the possible present knowledge of the simultaneous values of various quantities with which the…

— Werner Heisenberg

“Quantum physics speaks in chance, with the syntax of uncertainty. You can know the position of an electron but you cannot know where its…

— David Mitchell

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

— David Christian

“One the grand paradoxes of existence and nonexistence is the uncertainty of uncertainty. Even uncertainty can be uncertain. However, can you be certain of…

— Lionel Suggs

“If we can somehow control the probability of certain improbable events, then anything, including faster-than-light travel, and even time travel, is possible. Reaching the…

“One of the most curious consequences of quantum physics is that a particle like an electron can seemingly be in more than one place…

— Marcus du Sautoy

“Uncertainty is the only certainty in this world.”

— Andrew Gross

“Uncertainty is an uncomfortable position. But certainty is an absurd one.”

— Voltaire

Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle.

— Edward Witten

I think that when we know that we actually do live in uncertainty, then we ought to admit it; it is of great value…
