| Fall, 2016: I teach the multivariable course Math21a college course and the extension Math E320 course this fall. Some updates in graph geometry, like about graphs related to counting and a combinatorial observation about primes in quaternions. Fall 2016 Photos. SIAM meeting talk September 30, 2016 and related: Math-candy.com

| Summer, 2016: I teach the multivariable course Maths21a. A HCRP PDE project. A 15 min Calculus refresher. Some experiments with primes and matrices as seen here or in this animation. Summer 2016 panoramas and a new google earth experiment. Travel photos:Rheinfall, Salmenfee, Uhwiesen and Israel.

| Spring, 2016: I teach the linear algebra course Math21b (Canvas admin), this spring semester. Providence end of year. New in graph geometry: Gauss-Bonnet for multi-linear valuations and some slides on Wu characteristic with miniblog, a row reduction, determinant, and PDE song. Some winter 2016 and spring 2016 panoramas.

| Fall, 2015: I teach multivariable Math21a (Canvas)), this fall as well as Math 320E in the Extension school (Canvas)). New in graph geometry: Spectra of barycentric refinements:ArXiv (miniblog) as well as a a discrete Sard result (miniblog) and more Chladni pictures. Photos of Summer 2015 travels, a Freshmen advising lunch, and November river panoramas. A rewrite of universality. On Barycentric characteristic numbers.
