In any attempt to bridge the domains of experience belonging to the spiritual and physical sides of nature, time occupies the key position.

The electron, as it leaves the atom, crystallises out of Schrodinger's mist like a genie emerging from his bottle.

I believe there are 15, 747, 724, 136, 275, 002, 577, 605, 653, 961, 181, 555, 468, 044, 717, 914, 527, 116, 709, 366, 231, 425, 076, 185, 631, 031, 296 protons in the universe and the same number of electrons.

Schrödinger's wave-mechanics is not a physical theory, but a dodge - and a very good dodge too.

The physical world is entirely abstract and without actuality apart from its linkage to consciousness.

The pursuit of truth in science transcends national boundaries. It takes us beyond hatred and anger and fear. It is the best of us.
