Classical physics has been superseded by quantum theory: quantum theory is verified by experiments.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

Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can then use…

Quantum physics is no longer an abstract theory for specialists. We must now absolutely include it in our education and also in our culture.

— Claude Cohen-Tannoudji

The special theory of relativity owes its origins to Maxwell's equations of the electromagnetic field.

— Albert Einstein

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