Hilbert’s Third Problem (A Story of Threes)

Submission statement: this is a remarkably accessible presentation (with hand-drawn diagrams!) on the concept of geometric invariants and their use in the proof of an early 20th century problem about equivalence between polyhedra.

This is excellent mathematical writing! I found it very approachable and superbly well researched.

Great writeup. Why is it on the MIT admissions website?
