The Aperiodical turned three on Saturday. I was away attending my brother’s wedding, but I couldn’t let the birthday pass without mention.

C: $K_A m; \\ K_B d.$
A: $\neg K_A d; \\ m \vDash \neg K_B m.$
B: $d \not\vDash K_B m; \\ (K_A(\neg K_B m)) \vDash K_B (m,d).$
A: $m \wedge K_B(m,d) \vDash K_A (m,d).$
Albert, Bernard and Cheryl have had a busy week. They’re the stars of #thatlogicproblem, a question from a Singapore maths test that was posted to Facebook by a TV presenter and quickly sent the internet deduction-crazy.
First of all: no, it’s not meant to be answered by an average Singaporean student. It’s a hard question from a schools Olympiad test.
A headline appears on my screen: “Ancient and Modern People Followed Same Mathematical Rule To Build Cities”, on Slashdot.
Ooh, I get to break out my “holy power law, Batman” image again! Yippee!
Ctrl+F “power law” – no hits. That’s odd.
Bread & Kisses is a short film by Katherine Fitzgerald about a mathematician who discovers love – I know, I know, you’ve heard this one before – but it also contains a mathematician who moves to the Alps to get more skiing in, so it’s the most realistic film about mathematicians ever. It also features the emotion of love in a star turn as an epsilon term.
Although it contains the line, “you forgot the most important ingredient: love”, so don’t get your hopes too high.
To celebrate Christopher Zeeman’s 90th birthday and their own 150th, the London Mathematical Society have opened an online archive of Sir Christopher’s work.
My way of celebrating π day is to rummage through my trove of obscure writings and dig up some interesting esoterica on the subject of that constant. Here’s what I found.
In case you’re new to this: every now and then I encounter a paper or a book or an article that grabs my interest but isn’t directly useful for anything. It might be about some niche sub-sub-subtopic I’ve never heard of, or it might talk about something old from a new angle, or it might just have a funny title. I put these things in my Interesting Esoterica collection on Mendeley. And then when I’ve gathered up enough, I collect them here.
We can’t hope to keep up with all the π action around the internet today, so here’s a live stream of #piday tweets.
