Binary Won, Ternary was right

Описание: Computers count in ones and zeros. But on paper, three symbols are better than binary.

In this video we work out why base 3 wins in the maths, learn balanced ternary (digits −1, 0, +1), where negative numbers and rounding come for free, and check it with real Python.
