Discover the Setun: First Ternary Computer Created in the USSR

The Complex History of Setun

Setun, the world's first ternary computer, was developed at Moscow State University in 1958. This revolutionary machine utilizes "trits" (ternary digits) instead of "bits" (binary digits). Unlike binary systems that operate on two discrete values, Setun works based on a system known as balanced ternary, where each digit can be -1, 0, or 1. This allows for a multiplication of ways to assign meaning to each state.

An interesting aspect is that base-3 (also known as radix-3) is the most efficient method for representing numbers, considering that 3 is the closest integer to the natural growth constant, the base of the natural logarithm, e, which is approximately 2.718 ≈ 3.
