    From Zero to Hero: a Euclidean proof

    By Colin Beveridge. Posted June 18, 2024

    It used to live, unloved, in the A-level formula book: a mysterious result relating the area of a triangle to its sides. The most interesting thing about it was its name: Heron’s formula. (As far as I can make out, the chap’s name was Hero of Alexandria, and if you do a possessive in Greek…

    Table of primes and the sequence of primes generated. Table is in the linked blog post.

    A few weeks ago I heard someone casually refer to ‘that formula of Euler’s that generates primes’. I hadn’t heard of this, but it turns out that in 1772 Euler produced this formula: \[ f(x) = x^2 + x + 41\text{.} \] Using this, \(f(0)=41\), which is prime. \(f(1)=43\), which is also prime. \(f(2)=47\) is…
