## Wild About Math bloggers 11/19/10

[ The latest roundup is at Equalis. Here's last week's edition. ]

Fun happenings this week in the blogosphere.

I'm excited to discover that Sue from Math Mam Writes... interviewed James Tanton. I missed the interview but a recording is here. Mr. Tanton is a very talented mathematician, Math teacher, author of fantastic Math books.

Can bacteria solve sudoku puzzles? Sort of. Check out this New Scientist article.

From Math Less Traveled:

What happens when you hook up three projectors to a single video camera, and then point the camera at the projected images?

RIDICULOUSLY AWESOME THINGS, that’s what!

Mathematica 8 has been announced.

But probably the single greatest—and most surprising—new capability of Mathematica 8 is one that cuts across all areas: the integration of Wolfram|Alpha into Mathematica, and the notion of free-form linguistic input.

Alex Bellos introduces us to solids of constant width beyond the obvious sphere.

If you ever wanted to prove Euler's Formula (V-E+F=2 for any convex polyhedron) check out this article at the Geometry Junkyard. Hat tip to Ars Mathematica.

Maria at Math Accent reviews a book, Sliceforms. It's a twist of sorts on Origami.

Finally, I'll leave you with a puzzle. Fun with Num3ers has an intriguing puzzle:

If we take the numbers from 1 to 15 (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15) and rearrange them in such an order that any two consecutive numbers in the sequence add up to a perfect square, we get,

8 1 15 10 6 3 13 12 4 5 11 14 2 7 9 9 16 25 16 9 16 25 16 9 16 25 16 9 16ask the readers the following:

Can you take the numbers from 1 to 25 to produce such an arrangement?

How about the numbers from 1 to 100?
