Happy Half Tau Day 2024

Happy Pi Day—or, as I prefer to call it, Half Tau Day!

I’ve got some more updates planned for my math learning project, including a post on a challenging “high school” geometry problem and a review of The Art of Problem Solving, Volume 1. Watch this space for notifications.

In the meantime, now’s a good chance to mention the Official Tau Tee Shirt and the print edition of The Tau Manifesto. Get them now in advance of Tau Day 2024! (How cool is it that Google knows when that is?)

Happy Half Tau Day, everyone!
