Tips for Mathematical Handwriting (2007) (johnkerl.org)

I came across this article today when looking up how to differentiate lowercase upsilon and nu.

My lowercase x and n look quite similar, especially in subscript-size. When I was an undergraduate, I got marked down once because the marker thought I had written a limit as x (rather than n) tends to infinity, which made no sense in the context. Nearly 20 years later, I’m still bitter that I wasn’t given the benefit of the doubt.
