yesterday was π day in the united states (3/14), but it won’t be π day until 22 july (22/7) in the rest of the world.
I thought we were all sufficiently geeky to see the significance of today, 3/14.
If 3/14 isn’t enough, look at the rest of the schedule: 3/14, at 1:59, for 26 minutes. That’s 3/14 1:59 26′. Or, smooshed together, 31415926.
The 22/7 part was especially obscure, it was supposed to be a joke about how 22/7ths (3.1428571428571428571428571428571…) is an excellent approximation for Pi (3.1415926535…), and thefore 22/7 (July 22nd for those European metric chaps) is an approximation for Pi day (3/14). There’s a good lesson for engineers in this, as 22/7ths is a “good enough” version of Pi for all but the most demanding applications, despite being a (literally) infinitely less complex expression than Pi. Something for us to keep in mind to temper the natural tendency to “overengineer” solutions.

2006 is the 300th anniversary of Pi, in that the first recorded use of the Pi symbol to represent this ratio was in a book in 1706, so maybe we’ll have a bigger celebration next year. Any maybe a real blowout in 2020 (314 years after publication)?
now you know.
meanwhile, somebody sent me a check, so now i have to go make a pipe. it’s a good thing i have a whole bunch of creative outlets (i’ve made 3 more sets of runes since sunday, and i’m now the sound effects coordinator – read "funny noise maker" – for the cirque and the players), otherwise i’d really be going nuts.
i wonder if
1) Does my username suit me?
2) Is my journal’s title cryptic or descriptive? What do you think it means?
3) Does my journal expand your knowledge of me?
4) Do you think my bio describes me well?
5) Which of my interests surprises you the least?
6) Which of my interests surprises you the most?
7) Which of my interests needs explaining?
8) Which of my userpics suits me best?
9) Which of my userpics suits me least?
10) Which of my userpics needs explaining?
