Today is a senior skip day so we talked Twin Prime conjecture and the new discovery. Used the Slate article and Mr. Honner’s writeup for basis. Fantastic. Also wrote up a quick python script to print twin primes. Runs pretty quick, finds the first half a million in around 10 minutes. So no picture today, but here’s some code 🙂

from math import sqrt def prime(n): for i in range(2,int(sqrt(n))+1): if (n%i == 0): return False return True count = 1 numberfound = 0 previous = 0 while True: if count % 5 != 0: if prime(count): if prime(count + 2): numberfound += 1 print "number found ", print numberfound, print "twin primes", print count, print count + 2, print " the gap is ", print count - previous previous = count count = count + 2
