I'll give a talk on math constants today, 11 AM Chicago time, 18 Dec 2025. You can see the picture of Ford Circles that somehow put me into Facebook Jail. https://t.co/Q72jTqwj85

2025 = 1³+2³+3³+4³+5³+6³+7³+8³+9³ = (1+2+3+4+5+6+7+8+9)². If you slice the cubes into squares, you can make a side 45 square. This is known as the Partridge problem, and is based on Faulhaber's Formula or Nicomachus's Theorem.

@nprscottsimon Satire goes old. Consider JOE MILLER’S JESTS, 1865. Scrooge, buying a turkey. “He shan’t know who sends it. It’s twice the size of Tiny Tim. Joe Miller never made such a joke as sending it to Bob’s will be!” They were stale jokes 150 years ago.

@Andiluv Did you know your name is an anagram of the Star Wars show "The Mandalorian". You should be on that show.

A math gem from the past.

This is the first-known Knight's Tour where a Queen can be placed on a square (in this case #35) and attack all of the prime numbers. The Knight's Tour starts at "1" and ends at "64." Discovered by Mike Keith in 1998. See https://t.co/n1fimFisiF

@Joseph_Fergie can you comment on the weird flag?

[Ed Pegg @mathpuzzle]

The tricolor quad divides into three quads similar to itself, making this an irreptile. If the smaller square has area 1, what is the area of the larger square?

My mind is being blown today sitting outside getting a sneak peek at a LitRPG math adventure novel by @mathpuzzle Ed Pegg. It's my first time to explore this genre, and I really got an awesome book to start the fun.

[math prof @mathematicsprof]

Great demonstration.
