📚 Second quantization allows us to do quantum mechanics in systems with a variable number of particles. This means that we need to be able to add and remove particles, and the creation and annihilation operators allow us to do this. For bosons, these operators obey a set of commutation relations that capture, in a compact manner, all the subtleties associated with the totally symmetric nature of bosonic states.
