Math & numbersMetaprimesI enjoy math and logic puzzles. In 2003 I came across an interesting mathematical curiosity involving mapping numbers encoded in normal, “additive” binary to numbers encoded in an alternate, “multiplicative” binary. You can read about it here.
Interesting integer sequencesThe Online Encyclopedia of Integer Sequences is filled with other interesting (some would say beautiful) sequences; here are some of my favorites. I’ve also submitted a few sequences to the OEIS myself; there’s a list of them here.
Collatz tree / 3x+1 conjectureThe Collatz conjecture (also known as the “3x + 1” or “3n + 1” problem) involves a simple repeated formula, but yields some interesting sequences. Read more about it here.
Prime signaturesPrime signatures are another interesting mathematical topic; read more about them here.
