No one really understands quantum mechanics.

With quantum physics, who needs drugs?

The Quantum Universe has a quotation from me in every chapter – but it’s a damn good book anyway.

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 a wonderful problem, because it doesn’t look so easy.

I think I can safely say that nobody understands Quantum Mechanics.

If you think you understand quantum mechanics, you don’t understand quantum mechanics.

But this quantum only takes on its full significance when we try to define it with regard to a concrete natural movement – that is to say, in duration.

Relativity. Gravity. Quantum. Electrodynamics. Evolution. Each of these theories is true, whether or not you believe in them.
