Yes, there’s another draft chapter of MODA online. Before we get to that, however, here is a picture sent in by arguably the greatest fan of cp4space:
You may remember Vishal from the games of Hackenbush he played against his adversary, Gabriel. There’s really nothing more to say on this subject, so here’s the updated chapter list. The latest chapter mainly involves areal coordinates, but with some extra bonus material on Huygens-Steiner (parallel axis theorem if you’re applied) and Cayley-Menger determinants.
What’s wrong with this perfectly innocent-looking diagram…?
- Combinatorics I (enumerative and geometrical combinatorics)
- Linear algebra
- Combinatorics II (graph theory)
- Projective geometry
- Complex numbers
- Triangle geometry
- Areal coordinates
- The Riemann sphere
- Diophantine equations
- Conic sections
- Further reading
Thanks go to Tim Large for some helpful suggestions he gave me whilst in the laundrettes at midnight. These will be incorporated into the final revision of MODA. If you have any ideas, please either send me an e-mail or comment on this post.
