Sladana presented Shifrin 2.3# 2b, Emily presented 2.3#12. This gave me the opportunity to talk about Gauss’ Theorema Egregium. This is a central result of classical differential geometry, and one of the motivating results for modern differential (Reimannian) geometry.
We had volunteers for the parts of #7. Let’s do that next time.
Start reading section 2.4. I’ll bring project descriptions with entry points in the literature next time.
