A Physicist Does Math

Just for fun:

Friday, November 18, 2011


I'll be giving a talk this spring titled "Infinite Possibility: The Importance of Mathematical Play." One of my three topics will be M. C. Escher's work with tessellations. I was sharing about this with a friend today and was surprised to learn that Escher is not universally known. His work has been a part of my life so long I thought everyone was familiar with it, so I decided to post a few of my favorites of his work - each having some mathematical aspect to it.

Floods Have Slit the Hills

The Brain, within its Groove
Runs evenly-and true-
But let a Splinter swerve-
'Twere easier for You-

To put a Current back-
When Floods have slit the Hills-
And scooped a Turnpike for Themselves-
And trodden out the Mills-

Emily Dickinson (1830-1886)
