Algebra Quote by Richard P. Feynman

“When { Born and Heisenberg and the Göttingen theoretical physicists} first discovered matrix mechanics they were having, of course, the same kind of trouble…

“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

People get a lot of confusion, because they keep trying to think of quantum mechanics as classical mechanics.

— Sidney Coleman

Although quantum mechanics has been around for nearly 70 years, it is still not generally understood or appreciated, even by those that use it…

— Stephen Hawking

The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.

— Alain Aspect

Since the founding of quantum mechanics in the 1920s, theoretical physics had nurtured an extremely radical tradition.

— David Gross

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

“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

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

“Wolfgang Pauli, in the months before Heisenberg's paper on matrix mechanics pointed the way to a new quantum theory, wrote to a friend, "At…

... The approach of von Neumann and Connes to the use of non-commutative algebra in physics is naive, the situation is much more complicated.

— Israel Gelfand

Quantum field theory was originally developed for the treatment of electrodynamics, immediately after the completion of quantum mechanics and the discovery of the Dirac…
