Paul Sally vs. Tiger Woods

Paul J. Sally, Jr., Professor Mathematics at the University of Chicago. Photographed at the Legacy of R. L. Moore conference in Austin, Texas, July 2008

My friend and U of C classmate pointed out to me an interview in a recent issue of the Chicago Maroon with Paul Sally, Professor of Mathematics and mentor to generations of mathematicians and mathematics educators. He has a few good words about the practice.

Conference tweets broadcast beyond hotel ballroom

Saturday, July 18, 2009 - 6:44pm

This is not a "Why I tweet" post nor is it a "What twitter is for" post. But it's a nice anecdote about how twitter works in interesting ways.

We've just wrapped up the 12th annual Legacy of R.L. Moore Conference in Austin, Texas. It's one of my favorite conferences and I decided to see if I could organize some collective twittering.

SlideShare now hosts documents

Wednesday, April 29, 2009 - 8:34am

I just found out that SlideShare allows you to upload portrait-oriented documents (like articles and handouts) as well as landscape (presentations). That's good for me, since I use SlideShare a lot for presentations but haven't been as good at sharing worksheets and their solutions. I've used scribd for that stuff but for whatever reason I haven't been as diligent at uploading. One-stop shopping will help.

Here's an embed of a SlideShare-hosted worksheet:

Move is complete

The move is finished; I'm finally down in WWH 624.

Movin' on Down

Monday, April 6, 2009 - 8:34am

Sometime in the week of April 13 I'll be moving my office from WWH 718 to 624 (the building is being de-asbestos-ized floor-by-floor). My phone number will remain the same. Once it's official I'll update my contact info.

Stretch table row heights in LaTeX

Friday, April 3, 2009 - 1:08pm

Like Naradmuni, I'm always forgetting the simple command to make the rows of a LaTeX table bigger.

\renewcommand\arraystretch{MyValue}% (MyValue=1.0 is for standard spacing)

The sky is not falling (anymore? yet?)

Thursday, March 19, 2009 - 12:25am

A few months ago David Bressoud (incoming president of the MAA) wrote an article for Notices of the AMS called "Is the Sky Still Falling?" It refers to a 1995 Notices article (titled "The Sky is Falling") which worried about a rapid decline in the number of students enrolling in mathematics courses.

Bressoud's article contains good news and bad news. The good news is that enrollment in college math courses is up. One bit of bad news is that enrollment in all college courses is up, too, and the percentage of enrollments which are math courses continues to drop.

Yikes!

I knew the economy was bad, but a reverse lottery seems like a poor idea to fix it.
