Uncertainty
Position and speed can't both be known. The universe forbids it.

Six ways into the same idea — from bedtime story to chalkboard. No order required.

Told like a bedtime story.
For a curious 10-year-old. No jargon. Just a picture in your head.
If you want to know where a ball is, you look at it. If you want to know how fast it's going, you watch it for a second. For everyday-sized things, you can know both as accurately as you like. For the very smallest things, that is suddenly not allowed. The smaller you go, the stricter the trade-off: the better you pin down WHERE a tiny thing is, the worse you can tell HOW FAST it's going, and vice versa. This built-in trade-off is called the uncertainty principle, and Werner Heisenberg figured it out by writing a paper that nobody, including Heisenberg, fully understood at first.
§ Strange but true
- 01You cannot know a particle's exact position AND exact speed. The universe forbids it.
- 02It's not a measurement limit — it's baked into reality. Particles literally don't have both.
- 03Tighten one, the other blurs. It's the trade the universe makes with you.
