Linear versus Exponential Change
Captions available
The idea
Linear change adds a constant difference per step; exponential change multiplies by a constant ratio per step — and the ratio wins every long race.
In practice
Adding 2 from 2 gives 2, 4, 6, 8; doubling from 2 gives 2, 4, 8, 16 — from a tie, the doubling pulls away by step three.
