Scientist turned systems engineer by day, I enjoy recreational math, esp. mental approximations and properties related to the prime factorization of a number (e.g., # of divisors, powerful numbers, smooth numbers). I'm also interested when half-integers share a property of integers, such as Pronic numbers, which are essentially the squares of half-integers. For something else intriguing, check out the Sacks number spiral.
