Solved cryptogram
One short equation ties together the five numbers that matter in mathematics, and nothing else.
Mathematics Facts, sourced to Wolfram MathWorld.
What it means
Euler's identity relates e, pi, the imaginary unit, one and zero in a single line with an equals sign and nothing left over. It is regularly voted the finest equation in mathematics, and the reason it feels surprising is that the five constants arrive from completely unrelated corners of the subject: growth, geometry, algebra, counting and nothing.
The claim comes from Wolfram MathWorld, and the page it comes from was read on 2026-08-27 to confirm it still says this.
This is not the kind of claim that goes out of date, which is why it was set as a puzzle rather than a fact with a shelf life.
