Dirac Equation
Why is it interesting?
It's the correct equation of motion that describes free spin $1/2$ particles.
In fact, Dirac's equation for the electron must be rated, alongside the Maxwell and Einstein equations, as one of the Great Field Equations of physics.page 289 in "The Emperors new Mind" by Penrose

Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party.

- For an elementary derivation and a discussion of what the solution of the Dirac equation mean, see Physics from Symmetry by Schwichtenberg
- Alternative, two possible derivations can be found at page 100ff in Relativistic Quantum Mechanics by Paul Strange
- A great discussion can be found in chapter 10 of the quantum field theory book by Matthew Schwartz.
- Another great discussion, especially of question how many degrees of freedom a Dirac spinor has can be found in http://www.damtp.cam.ac.uk/user/tong/qft/four.pdf
