Graphic symbols re primes
- I want to create "a certificate" relating to prime numbers to give to
students. What graphic symbols, icon, formulas, portraits (with
sources), historical themes, could be used to give a real feel of the
topic on the certificate ?
I would like to include an aspect of Eratosthenes' Sieve among the
graphics and something to show the Goldbach Conject. Any specific
ideas on how to show these two themes? Are any of the historic
players on postage stamps ?
