The UnKnot Conference

Two weeks ago, the first UnKnot Conference was held in Granville, Ohio at Denison University. And no, UnKnot does not stand for a conference devoted to the properties of the trivial knot, which would be short conference indeed, but rather for the Undergraduate Knot Theory Conference. Organized by… Continue reading »

Mathematics and the Iranian Elections

One of the many things I love about mathematics is that results initially discovered in one realm pop up in surprising places. A terrific example is Benford’s law of digit bias (those taking Math 341 in the fall will get to learn a lot more about this!). Benford’s… Continue reading »

Compactness

In my opinion, compactness is the most important concept in mathematics. Here’s an article, recently published in Pro Mathematica, that tracks compactness from the one-dimensional real line in calculus to infinite dimensional spaces of functions and surfaces. Continue reading »

He was recently given a full retrospective by the Tate Modern Museum in London, which I had the opportunity to see in December 2008. Meireles’ intriguing and aesthetically seductive installations… Continue reading »

It was that we began to switch from teaching statistics as a mathematics course to teaching the art and craft of statistics as its… Continue reading »
