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

Theorists tend to peak at an early age; the creative juices tend to gush very early and start drying up past the age of fifteen-or so it seems. They need to know just enough; when they're young they haven't accumulated the intellectual baggage.

Neutrinos ... win the minimalist contest: zero charge, zero radius, and very possibly zero mass.

One of the major ingredients for professional success in science is luck. Without this, forget it.

The physicists defer only to mathematicians, and the mathematicians defer only to God.

Theorists write all the popular books on science: Heinz Pagels, Frank Wilczek, Stephen Hawking, Richard Feynman, et al. And why not? They have all that spare time.
