David Bachman

David Bachman is a professor at Pitzer College in Claremont, CA, where he teaches courses on mathematics, computer science, and data science. He has a PhD in mathematics from the University of Texas at Austin, and has published over 20 research articles, three books, and received two grants from the National Science Foundation. Thirteen years ago David's background in mathematics and his affinity for working with his hands converged when he began to experiment with 3D printing mathematical models. Since then he has created unique two and three-dimensional pieces by using several CAD modeling packages (most notably, Rhino 3D and Grasshopper), a variety of laser cutters, 3D printers, pen plotters, and a garage full of power tools.

An artistic illustration of a tree with a light source behind it, creating a glowing effect.

"Mean curvature" is one way in which mathematicians measure how a surface curls in space. By virtually "growing" a surface in the direction of its mean curvature, organic shapes such as this piece can spontaneously form, exemplifying the inherent aesthetic beauty of mathematics that is often invisible in the equations that describe it.
