One year ago today, Batman set up this site and wrote our very first post. It was seen by approximately 3 people. At that point I had a different username, but then I saw Batman and TwoPi’s names and I got jealous and picked the Greek symbol Xi (Ξ) because in grad school someone had told me once about a class where the prof was using Ξ for some variable, and it occurred in a fraction. The top was just Ξ, but the bottom was Ξ with a bar on top. The fraction ended up looking like this:
I thought that was about the coolest fraction I’d ever seen, and I would have been Xi-over-Xi-bar if I could have, but Xi was the closest I could come.
In thinking about the posts I’ve written, my artistic abilities are rather limited (as any of my students will tell you) so I’m disproportionately proud whenever I manage to create pictures for the posts. And it’s been a surprise (not any more, but at first) how often Godzilla makes guest appearances. He’s like Charo on the Love Boat: once he jumped into the blogging world (with a photo of himself eating Buffalo-Chicken Dip) he hasn’t looked back.
Happy Anniversary 360! And since the Anniversary falls on such an auspicious day, I’ll share one of my favorite sophomore-level math jokes:
Q: Why do mathematicians think that Halloween and Christmas fall on the same day?
A: Because 31 Oct = 25 Dec.*
* Think 31 Base 8 and 25 Base 10
