In a wild and wonderful world...

This post is nearly two months overdue. Right. On with it, then.
You see, the chemists have a complicated way of counting: instead of saying "one, two, three, four, five protons," they say "hydrogen, helium, lithium, beryllium, boron."

--Richard P Feynman, in QED: The Strange Theory of Light and Matter*

Richard Feynman called it a wild and wonderful world of quantum physics, where the very particles of light dare travel at above and below the speed of light (and not necessarily in straight lines), where electrons go backwards in time. And then he dared to go accuse the chemists of complicating counting.

Speaking of counting, he had us count 584 beans and take out 236**, and have a marvelously good time at it. Genius, he was.

Ooh, this is the Feynman Van, with Feynman diagrams painted on the side.

QED: The Strange Theory of Light and Matter is a collection of four lectures where he seeks to explain, to a non-specialist audience, the theory of Quantum Electrodynamics, without a single equation.


**metaphorically speaking, that is.
