San Francisco, CA -- On view at \href{https://www.artsy.net/crown-point-press}{Crown Point Press} is an exhibition of etchings by scientists and mathematicians, September 4 - October 27, 2015. 
\end{quote}

We came across \href{https://www.artsy.net/show/crown-point-press-concinnitas-the-art-of-the-equation}{this set of beautiful etchings on Artsy} depicting mathematical equations. We decided to reproduce them on Authorea, using our equation editor and some LaTeX. Here's the result.
