Solved cryptogram
Compound interest paid out ever more often approaches a fixed limit rather than growing forever.
Mathematics Facts, sourced to Wolfram MathWorld.
What it means
Lend a coin at a hundred percent annual interest and you end the year with two. Compound it monthly and you get a little over two and six tenths. Compound it every instant and you get a number close to two point seven one eight, and no faster schedule beats it. That limit is the number called e, and it turns up in radioactive decay, cooling curves and population growth for the same underlying reason.
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This is not the kind of claim that goes out of date, which is why it was set as a puzzle rather than a fact with a shelf life.
