The Department of Mathematical Sciences at Appalachian State University has multiple tenure-track openings, in mathematics, mathematics education, and actuarial science this year. If you or someone you know might be interested, check out https://mathsci.appstate.edu/faculty-searches for more information!

Now, unfortunately, at first read, you may get confused, and this is because there is a typo. When Cajori converts the number 8605729398715 to "small numbers", the resulting number is missing a leading 1. But he also handwaves the algorithm a bit, and so I decided to make a video walking through the algorithm. It's a fun example, using little more than understanding of place value, which you might find interesting!

Over on the bird app, a post by Howie Hua (where he used, essentially, negative numerals for subtraction) reminded me of an interesting note in Florian Cajori's "History of Mathematical Notations".

Until a few weeks ago, I was completely unaware of Niven's proof of the irrationality of π. It's a beautifully short (<1 page) and simple proof that I encourage you to check out.

I noticed, however, that it seemed it could easily be adapted to go a more differential equations route, so I rewrote it. If you're at all interested in DEs, check it out!

This is a small bandage on a much larger problem, but I hope it will provide access to at least a small part. I’d encourage others to do the same as you are able, particularly session organizers who may be able to organize these efforts more broadly #disruptJMM

(Coming from a discussion over on the bird app…)

For students and colleagues for whom attending JMM is unsafe (see the i/e blog post below by Piper H for a small sample of the reasons why), I plan to make my slides, the paper on which the slides are based, and a recorded version of my talk freely available online soon.

Come work with me! The Department of Mathematical Sciences at Appalachian State is searching for a new department chair. Application review begins 2/3/23 (it is currently incorrect in the ad, but 2/3/23 is the correct date).

Please share widely!

The area \(A\) of a circle of radius \(R\) is \[A=\mu R^2,\] where \( \mu \) is the principal eigenvalue of \[ \left\{\begin{array}{c} -u''(x) = \lambda u(x); x \in (0,1) \\ u(0)=0=u(1) \end{array} \right. \].
