this my attempt to collect those things that help me understand.

I'm mostly interested in the role of symmetries in fundamental physics. Most notes revolve around the following motto:

Further progress lies in the direction of making our equations invariant under wider and still wider transformations. P. A. M. Dirac in The Principles of Quantum Mechanics

Some notes here are really short and only refer to some paper that explains everything perfectly. Other notes are quite long, because I tried to sort my thoughts by writing them down. I rarely collect technical definitions as they can be easily found in the standard textbooks or at Wikipedia. Instead I try to collect side remarks that led to “Aha” moments.

If you find an error I would appreciate a short email to mail [at]
