"Despite their simple definition and role as the building blocks of the natural numbers, the prime numbers... grow like weeds among the natural numbers, seeming to obey no other law than that of chance, and nobody can predict where the next one will sprout."
(Don Zagier)
Having their students recite prime numbers seems to be a hobby of many maths teachers! Even though primes have had no real use for over 2000 years!! In fact, it's only since we have electronic devices that prime numbers have been able to stand their ground: they're an excellent choice for encrypting data. Without primes, safe surfing on the Internet would be much more difficult. The prime numbers have reached their "prime time", so to speak ;).
This poster highlights all the prime numbers up to 1089 in the form of a Ulam spiral. The 48th Mersenne prime, 257,885,161-1, the largest known prime number, makes for the crowning glory.
We would have loved to have seen this impressive number on the poster in all its numeric glory, but with 17,425,170 decimal digits, you'll forgive us as it's way too huge. If you were to print it on A4, you would need... let's see, 3, 5, 7, 11, 13... er, 1000s of pages!
By the way, it took a computer (no, not the old slow one in our office!) a full 39 days to even find this number. But you don't need a computer to be able to quickly remind yourself – you only need the Prime Time poster!
A poster reserved for only the cleverest... Let those numbers with their mysterious beauty into your life!
