# Course - Linear Algebra II HT23

This follows on from the definitions and results in [[Course - Linear Algebra I MT22]]

^{U}, first introducing the determinant and then the concept of eigenvalues and eigenvectors. It then introduces the notion of diagonalisability, and then proves the “spectral theorem” for real symmetric matrices in an inner product space, which means that every real symmetric matrix is diagonalisable.This was a really good course, it was lectured by James Maynard which was fun since he won the Fields Medal in 2022. It did feel like this meant like a lot of people in the lectures were taking every chance they could to correct any mistakes. In the final lecture he turned it into a game by keeping score like it was football – every time someone pointed out a mistake, it was one point for the audience, and every time someone mis-corrected him it was one point for him.
