* quantization. Uses a more or less standard way to guess the quantized system from the classical one using <Hamiltonian mechanics>.
* https://youtu.be/fnMcaq6QqTY?t=1179 remembers how to solve the non-field <quantum harmonic oscillator>
* https://youtu.be/fnMcaq6QqTY?t=2008 puts hats on everything to make the field version of things. With the <Klein-Gordon equation> <Hamiltonian>, everything is analogous to the harmonic oscilator
