exponential decay · half-life
Controls
Every half-life, half the remaining atoms decay. After n half-lives, only (1/2)ⁿ is left — the basis of carbon dating and nuclear physics.

Governing equation
Reading this result: Each half-life removes half of whatever remains, so the curve falls steeply at first and then flattens into a long tail.
