How a tiny squirrel taught Africa geometry, probability, and the stars
Long before chalkboards, African children learned trigonometry with a slingshot, probability with three snares, and astronomy by watching bushbaby eyes shine under the moon.
San grandfather teaching the “three-branch rule” – pure trigonometry without numbers
1. The Three-Branch Rule – Instinctive Trigonometry
Zulu and Xhosa boys were never allowed to shoot until the tree squirrel crossed exactly three branches.
On the fourth branch it hesitates → perfect moment.
That pause = distance ÷ leap speed ≈ 0.8 seconds → slingshot release timing.
Modern name: projectile motion + reaction latency.
2. The Marula Triangle – Early Probability
Venda and Tsonga hunters always placed three identical snares in an equilateral triangle under fruiting marula trees.
“The squirrel will choose one of three equal paths,” they said.
Catch rate tripled compared to random placement.
Modern name: uniform probability distribution in a symmetric field.
3. Bushbaby Moon Fractions – Practical Astronomy
Hadza and San only hunted galagos when “the moon is half a hand above the horizon after full dark”.
That’s roughly 8–12° altitude → maximum eye-shine with minimum shadow.
Modern name: angular measurement + optics.
4. BaAka Net-Hunt Semicircle – Cooperative Geometry
50 rainforest hunters formed a perfect semicircle with radius = 1.7 × tallest tree height.
Beaters walked inward → squirrels and duikers driven into nets with almost no escape.
Modern name: optimal search theory + circle theorems.
5. Dassie Parabola – Projectile Mastery
San children practised daily with light reed arrows on dassie-sized targets from 30–40 m.
They adjusted launch angle by “one finger width” per 10 m → hitting moving targets consistently.
Modern name: parabolic trajectories and iterative correction.
6. Sharing the Kill – Modular Arithmetic
BaAka rule: “One portion for every five net-holders, plus one portion returned to the forest.”
Worked perfectly whether 11, 16, or 31 hunters showed up.
Modern name: division with remainder (mod 5 + 1).
The same little tree squirrel raiding your mango tree this morning
once carried the entire mathematics curriculum of a continent on its back.
No textbooks.
No rulers.
Just sharp eyes, hungry bellies, and ancestors who understood that
to feed the body, you must first measure the world.
