Today is Pi Day, which I actually remembered this year for a change. March 14, or 3/14 is also Einstein's birthday, so a fitting day of celebration for nerds everywhere. It seems next year's will be a big one though, since it will be possible to have a date and time of 3/14/15 9:26:53 - the first 10 digits of pi, which is as far as I can recite it without having to look numbers up.
You're supposed to have pie on Pi day, not surprisingly. I've got quiche planned for supper, so I suppose that's close enough. If I were the shopping type, though, I would be out on Cafe Press looking at T-shirts. Check these out. I think I particularly like the ones that say 'Irrational, but well rounded', and 'My PIN is the last 4 digits of Pi'. Also the one that says 'Come to the dork side. We have Pi'.
And yes, if you laugh at those, you should definitely be celebrating Pi Day.
