Quote by Leon M. Lederman

In modern times the belief that the ultimate explanation of all things was to be found in Newtonian mechanics was an adumbration of the…

A gifted experimentalist, and theoretician, in the best Newtonian tradition... His contributions to quantum measurements, and elucidative teachings on quantum mechanics, have not yet…

— Willis Lamb

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

— Brian Greene

It is a curious historical fact that modern quantum mechanics began with two quite different mathematical formulations: the differential equation of Schroedinger and the…

— Richard P. Feynman

“Isaac Newton was a brilliant British mathematician and physicist who came up with three laws of motion,”

— Jerome Pohlen

“Every problem in quantum physics had to be first “solved” using classical physics, and then be reworked by the judicious insertion of quantum numbers…

— John Gribbin

“These two discoveries, of relativity and of the quantum, each required us to break definitively with Newtonian physics. However, in spite of great progress…

— Lee Smolin

“he described his own ideals, the desire for fulfillment not just as a theorist but also as an experimental physicist. (In the second respect,…

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

— Edward Witten

“The first successes were such that one might suppose all the difficulties of science overcome in advance, and believe that the mathematician, without being…

“Unlike classical certainty, quantum systems describe likelihoods, not fixed outcomes.”

— Ludmila Morozova-Buss

Theoretical physicists live in a classical world, looking out into a quantum-mechanical world. The latter we describe only subjectively, in terms of procedures and…
