LMR-001 · Matter
Atom
You are mostly empty space — held together by rules.
§ A first look
§ Depths
Six ways into the same idea — from bedtime story to chalkboard. No order required.
L1 · Crayon
Told like a bedtime story.
For a curious 10-year-old. No jargon. Just a picture in your head.
Take a piece of paper. Cut it in half. Cut the half in half. Cut that one in half. Keep going with smaller and smaller scissors, ideally borrow some from a surgeon. Eventually you reach a piece so small that cutting it again would stop it from being paper. The tiniest pieces that everything is built from — your hand, your dinner, the chair, the air, your aunt's enormous fruitcake — are called atoms. They are way, way too small for any eye or any normal microscope to see. There are more atoms in one droplet of water than there are stars in the entire sky. Yes, including the stars you can't see. Yes, all of them.
§ Strange but true
- 01If the nucleus were a marble at the center of a cathedral, the nearest electron would be three football fields away. The rest is empty.
- 02You have never actually touched anything in your life. Your electrons hover a fraction of a nanometer above every chair, person, cup.
- 03Every atom in your right hand was forged inside a different star than the atoms in your left.
