physics

If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet.

Everything we call real is made of things that cannot be regarded as real.

In the history of physics, every time we've looked beyond the scales and energies we were familiar with, we've found things that we wouldn't have thought were there. You look inside the atom and eventually you discover quarks. Who would have thought that? It's hubris to think that the way we see things is everything there is.
