Google Books replaces the index

Indexes can be great tools for finding specific information in books. However, as we all know, they are often maddeningly incomplete. I was constantly frustrated when I was in graduate school studying for my analysis prelim exam. Royden’s Real Analysis (our text) had a terrible index. I ended up hand writing dozens of entries into…

Create your own word clouds

This post is not really math-related.  I discovered a cool website called Wordle, which you can use to generate custom word clouds. Here’s how Wordle describes itself. Wordle is a toy for generating “word clouds” from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text….

Should there be an FDIC equivalent for the “banks” that…

Student podcasts in a history of mathematics course

I would like to take this opportunity to showcase some of my students’ work from last year.  I taught a class called “Great Theorems and Ideas in Mathematics.”  It was an upper-level history of mathematics course with a focus on some of mathematics’ greatest theorems.  I used William Dunham‘s Journey Through Genius for a good…
