I am trying to understand the derivation for the DOS, I get stuck when they introduce k-space. Why is it necessary to introduce k-space? Why is the DOS related to k-space? Perhaps if someone could come up to a slightly different derivation (any dimensions will do) that would help.
My doubt ELI5: If we have a region full of potatos and we want to find the density of potatos we count the potatos and we divide by the area/volume, we don't need to go into potato-space.
