Hi! I'm the founder of the Twin Internet Prime Search, which is a project that looks for twin primes of world record size. I'm interested in all things related to number crunching. At one point, I held the world record for calculating the most digits (600,000,000,000) of the natural logarithm of 2 (0.693147...)
