This semester, I’m teaching Calculus II. Yesterday, students submitted homework on finding volumes of solids of revolution. As a quick primer on these shapes, a solid of revolution is generated by rotating a planar region about an axis. For instance, rotating the right triangle below about the vertical axis generates the cone to the right. […]

In the last post Doodling with Euler, we explored the Euler Characteristic with a sweeping doodle! Now, let’s apply it to some other images! First, consider this image of the Davidson College Wildcat logo. The image is constructed first as a stippling of the standard logo. Then, an algorithm is run that forms a Traveling […]
