Fall, 2015: I teach the multivariable calculus course Math21a (Canvas for admin)), this fall as well as Math 320E in the Extension school (Canvas for admin)). New in graph geometry: Spectra of barycentric refinements:ArXiv (miniblog) as well as a a discrete Sard result (miniblog) and more Chladni pictures. Photos Summer 2015 travels. Freshmen advising lunch. A rewrite of the universality result. And on Barycentric characteristic numbers.
Summer, 2015: I teach the multivariable course this summer. New in graph geometry: a Cartesian product (ArXiv). During a Santorini 2015, wrote on Jordan-Brouwer-Schoenflies theorem. Techno demos: Double pendulum and Chirikov or Game of Life demo in JS or Chladni figures for a graph. Projects in Maths21a. Run in Baltschiedertal.
Spring, 2015: After Nantucket end of year, February blizzards and snow affected also teaching. Math E320, needing some online lecture. Since I teach 21b something about Eigenvalues. Jan 12: Graphs with Eulerian Unit spheres, in graphgeometry, mini blog. Curliecue and Buffon javascript demo.
Fall, 2014: I teach the Harvard Multivariable calculus course this fall. Advising Lunch Aug 27. Tracing walks of Jean Piaget and Georges de Rham during visit in Salmenfee. Oct 5: a graph geometry update: Curvature from Graph Colorings and some variational problems in graph theory. Dec 22: some work on graph coloring [ArXiv] with mini blog [HTML], illustration [HTML], animation [YouTube] and slides [YouTube], [PDF].
