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…

Wobbly tables and the intermediate value theorem

Tomorrow I’ll be introducing the intermediate value theorem (IVT) to my calculus class.  Recall the statement of the IVT: if is a continuous function on the interval and is between and , then there exists a value such that .  In other words, achieves all of the intermediate values between  and . This is a very underappreciated theorem…

This week’s topic in…
