Jessica Wynne’s Do Not Erase: Mathematicians and Their Chalkboards makes the case for slower, low-tech tools in the classroom.

Roy Peachey:

In A Mathematician’s Apology, G. H. Hardy writes, “The mathematician’s patterns, like the painter’s or the poet’s, must be beautiful; the ideas, like the colors or the words, must fit together in a harmonious way. Beauty is the first test: there is no permanent place in the world for ugly mathematics.” Anyone who finds these words utterly baffling – maybe anyone who battled with long division or quadratic equations at school – should have a look at Jessica Wynne’s Do Not Erase: Mathematicians and Their Chalkboards.

Wynne, a professor at the Fashion Institute of Technology in New York, traveled across North and South America and into Europe to photograph mathematicians’ chalkboards. Nothing more. Not the classrooms in which those chalkboards were found or even the mathematicians who worked on them. Just the chalkboards and the mathematics that filled them. It might seem a niche project but the results are surprisingly beautiful. There really is no place in the world for ugly mathematics.

However, Wynne’s photographs tell only half the story. Accompanying each picture is a short meditation by the mathematicians whose work is seen on the chalkboards. These meditations focus not only on the mathematics, much of which is extremely high level, but also on the sheer physicality of the mathematicians’ work. We tend to think of mathematics as the most cerebral of disciplines, but in this book, we discover how mathematics involves the body just like any other craft.
