I wanted to live deep and suck out all the marrow of life, to live so sturdily and Spartan-like as to put to rout all that was not life, to cut a broad swath and shave close, to drive life into a corner, and reduce it to its lowest terms.
Henry David Thoreau, Walden
If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.
John von Neumann
Picasso drew math art: a bull in full and then simplified the figure to a few lines, to the essence of a bull. This is the role of mathematics in the sciences. She takes reality and distills it to its essence. She drives life into a corner and reduces it to its lowest terms.
