The paper is dedicated to the close analogy between these two theories - some problems lying at the very root of Spectral Geometry are viewed in the context of Semiclassics, and vise versa. The treatment starts from a very basic level and gradually goes into the deep, ending up with some rather up to date results. There are many examples concerning effective actions in QCD and String Theory, functional determinants, first integrals from asymptotic expansions, path quantization etc. The major theorems are only given brief explanations and simple constructive proofs, but some rather practical formulae are obtained in return. There is a small exercise at the end - obtaining explicit expressions for the spectral variations of the Robin problem for a planar domain. The final result is purely in the spirit of the familiar Sationary Perturbation Theory. The idea for investigating this particular problem (in the context of an old exact inverse result obtained by Guillemin and Melrose), very much motivating most of the work, belongs to my scientific advisor Dr. Petko Nikolov.
