Quantum mechanics/Casimir effect in one dimension. Abstract The Casimir effect is interesting because it introduces the concept of Ramanujan summation of the divergent series, 1+2+3+4+..., and because it offers experimental evidence that empty space is not truly empty. Every step in this derivation of the Casimir effect uses straight-forward and familiar mathematics.
