‘Shape’ Makes Geometry Entertaining. Really, It Does.

Ellenberg, a professor at the University of Wisconsin–Madison, is rather spectacular at this sort of thing. A seam in his narrative is a critique of how math, and especially geometry, has been taught. (His strategy for success in teaching is to employ more strategies; multiply approaches so students might find one that works for them.) He also takes a few well-aimed swipes at current depictions of the campus culture wars. The “cosseted” American college student might have launched a thousand Substacks, but have you heard of the “Conic Sections Rebellion”? Some 44 students, including the son of Vice President John C. Calhoun, were expelled from Yale in 1830, for refusing to take a geometry exam.
