Three of these make a proton. Alone? Nobody's ever seen one.

Told like a bedtime story.
For a curious 10-year-old. No jargon. Just a picture in your head.
You know how atoms are the tiny pieces that everything is built from? Plot twist: atoms aren't actually the smallest pieces. Inside an atom is a dense little lump, and inside that lump are even tinier things called quarks, glued together in groups of two or three. The strangest part: quarks cannot be alone. If you tried to pull one out by itself, the harder you pulled, the more it would refuse — and instead of getting one quark, you'd somehow end up with more quarks than you started with. Physics is sometimes a vending machine that gives you change in extra particles.
§ Strange but true
- 01You have never seen a free quark. They are physically forbidden from existing alone — pull two apart and the gap snaps a new pair into being.
- 02There are six flavors: up, down, charm, strange, top, and bottom. Physicists are not above a joke.
- 03Quarks make up only 1% of your mass. The rest is the energy of the gluons binding them — pure E=mc².
