I’m a little late to the party, but do go have a look at the third installment of The Carnival of Mathematics over at Michi’s Blog. Lots of good procrastination material!
The fourth installment is set to go up on March 23. And I will be the host! If you write any sort of math-related blog entry, let me know about it by Wednesday the 21st. Go here if you want to submit an essay, and many thanks to Alon Levy for making the submission process so simple. No more than two contirbutions per author plese. I’ve already received a fair number of submissions, and the deadline is still a ways away.
