xkcd: Cursive Letters (and the Langlands program)

[Jonathan Fine]

Hi

Today's xkcd is a scatter plot of readability and coolness for cursive
letters. The coolest and most readable is a cursive capital ell
$\mathcal{L}$.

Cursive Letters # https://xkcd.com/2912/

Modular forms and L-functions are central to some of the coolest
mathematical research today (in algebraic number theory and the Langlands
program). Perhaps one day that research will be readable by ordinary
mortals such as myself. Sadly, the Langlands program uses a roman capital L.
