Call me crazy. I’m not that huge a fan of decimal. We use it, I accept it. Any time the leading tens or hundreds changes, we feel the need to celebrate it over the others. So, 20th, 30th, 40th… 100th are more important birthdays.

Oddly 16, 18, and 21 are also important. Well, 16 is 2⁴ and the base of hexidecimal. 18 is 2*3². 21 is 3*7.

So I would like to celebrate the positive integer exponents of two… 2⁵ (32), 2⁶ (64), and maybe 2⁷ (128 could be possible soon?) … as important birthdays. We could throw in some others such as 3² (9), 3³ (27), 3⁴ (81), 5² (25), 6² (36), 7² (49), (8² is 2⁶ and 9² is 3⁴), and of course 10² (100).

Nevermind… I’ll just call myself crazy…
