TL;DR: 30 math quote bookmarks with any coloring book order by 9/9/2017; lots of quotes and links to interesting interviews with/profiles of mathematicians below.
In my “quotes by modern or non-Greek/European mathematicians” post I asked if people knew of quotes about math that I could Instagram, basically. While there are few comments on that post I got some ideas via Facebook and email. Thanks in particular to Edray Goins for pointing me to several of these sites — Edray’s a number theorist at Purdue and the president of NAM and writes a blog on Dessin d’Enfants, which I want to give the coloring book treatment someday, and gave me a bunch more links which I’ll put below. Anyhow, here are some cool quotes I found:
Do not give up, for that is ignorance and not according to the rules of this art … Like the lover, you cannot hope to achieve success without infinite perseverance. — Muhammad ibn Muhammad al-Fullani al-Kishnawi [ref Gwarzo, Hassan Ibrahim]
