Very excited to be at the American Institute of Mathematics in San Jose, CA, to spend a week at the workshop on free & open textbooks, MathBook XML, and all sorts of emerging options. Three things are totally clear from the outset: It’s an amazing group of 25-30 people here. So many cool projects, smart […]
Happy New Year everyone. Here are a couple of brief updates if you are planning to use Active Calculus in the upcoming winter semester.
