Math + War
Just happened to run into this on a data mining blog. A very provocative use of mathematics to understand Iraq and it’s connection to other world conflicts.

E8 might model a unifying physical theory
This blew me away today. The video is visually beautiful, but the article in the new scientist is great for someone like me with little or no physics.

New pi record!
A French software programmer claims to have set a new pi calculation record, extending the previous record by some 123 billion digits. I’d hate to verify that record.
Thanks, Rob, for sending this over.

Sue sent over this link and I wasted like 20 minutes on GraphJam this morning. Pretty fun. Thanks, Sue.

Math word controversy
101. Do you say “one hundred one” or “one hundred and one”? I found this usage conudrum over at A Phrase a Week, and then this link to a great post at Improbable Research. I’m not going to lose any sleep on the issue, but the proposed solutions at Improbable Research are good for a chuckle.

Equations Editor in Google
About two weeks ago I noticed an addition in my google docs “insert” menu. Google has introduced an equation editor to docs. I found out after the fact that equation editor has been there since mid-September. So much for my powers of observation? Needless to say this opens the product to a whole new set of uses for anyone like myself. I do warn against writing tests or anything that needs to be printed with it. The print preview/wsywig capabilities of g-docs are really primitive, and the equations are exported to the printer as low quality graphics. However, if your doc is living in the cloud, the mathematical expressions look great!
