The aether: Invented by Isaac Newton, reinvented by James Clerk Maxwell. This is the stuff that fills up the empty space of the universe. Discredited and discarded by Einstein, the aether is now making a Nixonian comeback. It's really the vacuum, but burdened by theoretical, ghostly particles.

By the grace of AEC, BNL, God, Green and Hayworth (alphabetical order), we should see neutrinos.

He [Democritus] is probably best known for two of the most scientifically intuitive quotes ever uttered by an ancient: 'Nothing exists except atoms and space, everything else is opinion'.

Physics isn't a religion. If it were, we'd have a much easier time raising money.

Democritus's work on the void was revolutionary.

The real goal of physics is to come up with an equation that could explain the universe but still be small enough to fit on a T-shirt
