When Intuition And Math Probably Look Wrong – Science News.

Great article on probability, math, intuition. Wish I hadn’t read it just*after* my Probability classes ended.

Still digressing after all these years…

20 Moves Or Less Will Solve Rubik’s Cube : NPR.

Unfortunately, as happens so often with NPR math stories, the actual content falls rather short of the potential. I say something on the math of this story over here.

P.S.

If you’ve never heard of Looney Labs, the company of the person interviewed here, check out their website. Several of their games are on my favorites list.

New at Cap’s Whiteboard, two amusing (open) problems I learned about recently.

Permalinks:

Made some progress on some of the math problems I’m working on. Results announced over at Cap’s Whiteboard.

In case anyone interested hasn’t seen them yet, the slides for the talk I gave at MathFest are over at Cap’s Whiteboard, along with some references.

This time on Cap’s Whiteboard, a quickie gem about combinatorial geometry. Is it possible to start with a rectangle, neither of whose sides has integral length, and cut it into smaller rectangular pieces, each of which has at least one integral side?

It has been said (by the mathematician Alain Connes) that you cannot understand the integers unless you understand this.
