## Happy tau day!

It is 6/28! Happy tau day—a day that is twice as fun a pi day! Let’s celebrate our new favorite mathematical constant:  Remember, as Bob Palais told us, is wrong! I’m a fan of tau.

## 12 scholarly hoaxes, randomly generated articles, and other tricky fun

Everyone loves lists. Just for fun, here’s a (very) loosely-organized list of scholarly hoaxes, randomly generated content, and other interesting tidbits. Some of these I learned about recently, some I’ve known about for a long time. Theorem of the day—This website creates randomly generated “theorems.” Rejecta Mathematica—This journal publishes only articles that have been rejected by peer-reviewed…

## Movie day in topology class: the Poincaré conjecture

Today was the last day of the topology class I’ve been teaching. I decided to devote the day to the Poincaré conjecture. I started by telling the students a little about the history of the problem. Then I showed them three videos. The first video was an excellent 50-minute lecture by Fields medalist Curt McMullen…

## Nice surprise

I was just informed that my blog was selected as one of the 50 Best Blogs for Math Majors [update: broken link]. I’m honored to be included with such a great list of math blogs.

## John D. Cook’s daily Twitter tips

One of the most prolific and interesting math bloggers and Twitters, John D. Cook (his blog is The Endeavor and he is @JohnDCook on Twitter) has been using Twitter in a very interesting way. In addition to his personal account, he has set up more than half a dozen daily Twitter messages on a variety of…

## Mathematical cousins and collaboration numbers

A couple days ago Michael Lugo at God Plays Dice shared a link to a mathematical relationships search. Enter the names of two people with PhDs in mathematics and it will spit out their academic relationship. For example, my advisor, John Franks, is my academic father and my good friend and collaborator Jim Wiseman is my academic…

## Steven Strogatz writes about the elements of mathematics in the NY Times

Yesterday the mathematician Steven Stragatz wrote the first article in a mulit-part series for the NY Times. In this first article, called From Fish to Infinity, he describes his intent. Crazy as it sounds, over the next several weeks… I’ll be writing about the elements of mathematics, from pre-school to grad school, for anyone out…
