Here are three Twitter feeds about math which are so worth following:

MAA
@maanow
MAA is the Mathematical Association of America. I'm enjoying the @jamestanton videos they're tweeting, which brings me to the next tweeter ...

James Tanton
@jamestanton
James Tanton lives in DC and came by way of Australia. His and the MAA's recent tweets about their Youtube video, Some Algebra, posits the following algebraic problem:Let a, b, and c be real numbers such that a  7b + 8c = 4 and 8a + 4b  c = 7. What is a^{2}  b^{2} + c^{2}?
The video is 5:48 min long as he wends his way to a solution while writing backwards on plexiglass. Can you solve the problem in less time (with or without writing backwards)?

Probability Fact
@ProbFact
If the algebra problem above was too easy for you and you're looking for a challenge, head on over to @ProbFact. It's run by @JohnDCook and his most recent tweet as I write this piece is the following: "Random inequalities IV: Cauchy distributions bit.ly/7MZWuK". yay!
Now here's the roundup of news about math.
