Wrong in Public is a new, hopefully very occasional, series on Roots of Unity. I don't like being wrong in public, but sometimes I make a mistake in a post, and sometimes mistakes are interesting.
A four-coloring of most of Europe. The 4-color theorem is fairly famous in mathematics for a couple of reasons. First, it is easy to understand: any reasonable map on a plane or a sphere (in other words, any map of our world) can be colored in with four distinct colors, so that no two neighboring countries share a color.Second, computers were instrumental in the proof of the four-color theorem.
Evelyns from Texas at the AJAS poster session. (Left: yours truly. Right: Evelyn Ho.) When I was at the American Association for the Advancement of Science meeting in Boston last week, I popped by the American Junior Academy of Science poster session featuring the work of high school scientists.
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.
Swirling Symmetry, mathematically-inspired art by Sandra DeLozier Coleman, who also writes mathematical poetry. This piece appeared in the 2013 Joint Mathematics Meetings art gallery.
Mathematicians attempting to untangle a human knot at a knot "flash mob" on January 11, 2013 at the Joint Mathematics Meetings. Image: American Mathematical Society Anyone with necklaces or lace-up shoes has some first-hand experience with knots, but believe it or not (knot?), there is an entire mathematical discipline dedicated to studying knots and some closely related concepts.
