I wrote a few blog posts while I was at the Joint Mathematics Meetings back in January, but now you can read some more comprehensive coverage of the meetings at the American Mathematical Society website...
A continued fraction....of love. About a month ago, I awoke from a dream totally psyched about the brilliant blog post I would write for Valentine's Day.
This blog is called "Roots of Unity" because in 2004 I thought it would be an awesome band name. Not the cover of my band's first album. Image courtesy of Gregory A.
On Sunday, I wrote about my public statistics session at ScienceOnline. Today, I'll tell you a little about my other session, Hands-on Math, co-moderated by Matthew Francis.
A member of the order Lepidoptera enjoys my favorite green space in Chicago, Garfield Park Conservatory. There's a 50 percent chance that this is a below-average lepidopteran.
