Dorky Poll: Numerical Trivia

I was most of the way through a long post in response to a donor request, when the power went out. It is, in fact, still out at home, and the power company’s web site lists an estimated restoration time of 1pm. As you might imagine, this puts something of a kink in my morning.

I’m too dispirited to attempt to recreate the lost post, so here’s a Dorky Poll to fill the gap. Jonathan Vos Post is out of town, so this is a good time to ask:

What’s your favorite bit of numerical trivia?

My personal favorite numerical coincidence is the fact that the number of seconds in a year is π x 107 to three digits (well, ok, it rounds up to 3.15…). It’s a handy calculational shortcut, and an odd fact that never fails to impress nerds who don’t already know it.

But there are lots of other cute little numerical facts like that. JVP is an endless font of them (and Jonathan, when you get back and read this, you are limited to posting one and only one in the comments. If you’d like to core-dump a huge list of numerical trivia, put it on a web site and post a link), but I’m sure other people reading this have their own lists. So what’s your favorite bit of numerical trivia?

And now, I’m going to the gym to shower in the locker room. Whee!
