Where did atom bombs come from?

Two of the most amazing things about the late, great twentieth century were:
  • someone learned how to split the atom;
  • someone else invented atom bombs!

Even more amazing - all this atom business started off with a mate of - guess who?

-Heraclitus, Anaximenes and Empedocles!

So hello to Democritus!

Well, he was born a while later than them, but he cerainly knew about them and was very interested in their ideas.

he agreed partly with Empedocles. Nothing really changed, he thought, because the stuff that things are made up of, is always the same. But he also disagreed partly with Empedocles. He said, "No, everything is not made up of Earth, Air, Fire and Water mixed together. Everything is made of tiny invisible blocks! Things come and go, but these tiny blocks are around forever!"

Guess what he called the tiny invisible blocks? Exactly! Atoms!

Did you know that the word 'atom' means 'uncuttable' in Greek?
