# On the book
* books 400 pages in 2011, 4 Parts
- based on thesis
* breakdown of chapters
- Only on p. 68: v. d. W. scientific education till 1928.
Text up to then is preparation of context to explain his life and contributions,
but it's also a nice elaboration in of itself!
# Chapter notes
## Chapter 1, Finite and infinite (Lie-) representation theory (18p)
* Sections on:
- Frobenius
- Burnside
- Schur
- Killing and Study and Cartan in one
- Weyl
- also notes on Brauer, Maschke, Deruyts, Hurwitz, Ostrowski, Infeld
## Chapter 2, Early development of QM (15p)
* Section on:
- Planck, Short one on the "Quantumhypothese"
- Bohr-Sommerfeld Atommodell
- Matrix mechanics, q-numbers, Wellenmechanics
- Relativistic QM equations
## Chapter 3, Groupd theory and Quantum mechanics till 1928 (25p)
* Focus on works on atom spectra and the (few) physicists promoting
representations theory to do it
- First permutation group, character theory, ...
Then SO(3) representation theory
Sections on:
- Wigner, lots of reflection on his works (papers) in that time.
- Neumann, who worked with him
- Heisenberg
- Heitler and London
- Weyl
- On the reception of group theory, but relativizes the common story
Text has focus on critique and complaints by
- Ehrenfest (Gruppenpest!)
- Slater

- Author studied Mathematics, so book contains some math.
- The math is high level, but there's not much of it.
But she is also not explaining math in the text.
