@jsiehler I'm playing your with so exciting! homepages.gac.edu/~jsiehler/ga (If I understand mechanism that one piece moving one time anyway is counted as 1-move, I may be able to reduce MOVES more!)

I made a new page of sliding block puzzles:

O is an interior point in the triangle 10, 26, and 36 units away from the three vertices respectively. Determine the side lengths a, b, and c, given that they are integers.

Who even needs the binomial theorem?
(20+25)²=2025
(30+25)²=3025
(68320+14336)²=6832014336
(60494+17284)²=6049417284
and so on.

Success!! With less than one hour to go! 2 weeks till pi day.

WTF THEY HAVE NAMES:??!??!?@?@?@?!?!?

I'm going to stream digits of π for all of π day!
(assuming my very hastily assembled streaming setup doesn't fall over and die)

The best memory of my internet life is that twitter.com/takatasennsei taught me the attached images. In Japanese, it seems to be well known as "3×3の完全虫食い算一覧" gensu.co.jp/saito/puzzle/a65wo

Our paper "Random triangles and polygons in the plane"] – in which we give a novel answer to Lewis Carroll's question "What is the probability a random triangle is obtuse?" – was published recently in the American Mathematical Monthly: doi.org/10.1080/00029890.2019.

Here's an animated version of Figure 2 from the paper, showing a geodesic in triangle space. The geodesic starts at the equilateral triangle shown, and the three curved paths show the tracks of the three vertices.

We've just released #Halcyon 2.2.5 with the following changes:
- Added French translation - Thanks to the unknown translator
- Improved German translation - Thanks @Givou
