Here are some fun findings from the blogosphere:

The latest Carnival of Mathematics has been posted. I've not had time to review it.

Thanks to Shecky, I read "Large cardinals: maths shaken by the 'unprovable' ," which is a disturbing look at the foundation of mathematics:

In the esoteric world of mathematical logic, a dramatic discovery has been made. Previously unnoticed gaps have been found at the very heart of maths. What is more, the only way to repair these holes is with monstrous, mysterious infinities.

Alex Bellos has a fun article on his blog, Cubism 2010, about the resurgence of interest in Rubik's cube. There's a lot of fun cube trivia in this article. And, I learned that there's a 7x7x7 cube.

Dave at Division by Zero has discovered that Google Translate now knows Latin. That's pretty exciting for anyone wanting to read ancient mathematical texts.

Here's a nice Youtube video that shows a fairly uncommon trick, how to quickly divide by 9. Hat tip to Fun with num3ers.

And, while we're talking about fast arithmetic, take a look at this blog article at Grey Matters.

Check out these Math jokes from Mathfail.com. Here's my favorite of this bunch:

Q: Why did the two vectors start an internet-based company?
A: Because they thought they had a good dot product.

And, here's an interesting "hand fractal" from Mathfail.com.

Finally, here's a great new cartoon from xkcd:

The title of image reads "Dear Reader: Enclosed is a check for ninety-eight cents. Using your work, I have proven that this equals the amount you requested."
