Framework Quote by Werner Heisenberg

“in experimental quantum mechanics we have run right up against what was previously perceived to be a purely philosophical barrier. The experiments are telling…

— Jim Baggott

All the quantum physics experiments have occurred chiefly on the atomic scale and we are taught to believe that nature's laws are consistent.

— Mitch Horowitz

“Quantum physics might seem to undermine the idea that nature is governed by laws, but that is not the case. Instead it leads us…

— Stephen Hawking

Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by golly it's…

— Richard P. Feynman

[Quantum mechanics] describes nature as absurd from the point of view of common sense. And yet it fully agrees with experiment. So I hope…

— Richard P. Feynman

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

— Brian Greene

Physics is the belief that a simple and consistent description of nature is possible.

— Niels Bohr

“Quantum mechanics extends this relativity in a radical way: all variable aspects of an object exist only in relation to other objects. It is…

— Carlo Rovelli

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…

— John Stewart Bell

Trying to understand the way nature works involves a most terrible test of human reasoning ability. It involves subtle trickery, beautiful tightropes of logic…

— Richard P. Feynman

Classical physics has been superseded by quantum theory: quantum theory is verified by experiments.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 very nature of the quantum theory ... forces us to regard the space-time coordination and the claim of causality, the union of which…

— Niels Bohr
