Abstract
In this chapter we try to arouse in the user a naïve feel about what the terms quantumsystem and quantum phenomenology underlie. The more mathematically-orientedreader, perhaps not so interested in the genesis of QM’s notions in physics, may skipthe sections following the first. From sections two, in fact, we will mention a numberof experimental facts, and briefly review the theoretical “proto-quantum” methodsthat led to the formulation of wave mechanics first, and then to proper QM. Manyof the physics details can be found in [Mes99, CCP82]. We shall eschew discussingimportant steps in this historical development, e.g. atomic spectroscopy, models ofthe atom (Rutherford’s, Bohr’s, Bohr-Sommerfeld’s), the Franck-Hertz experiment,for which we recommend physics textbooks (e.g. [Mes99, CCP82]). This overview ismeant to shd light on the basic theoretical model behind QM, developed in ensuing chapters.
Two are the possible outcomes: if the result confirms the hypotheses, you only took a measurement. But if the result contradicts the assumptions, then you made a discovery.

Notes
- 1.
Einstein was awarded the Nobel Prize in Physics for this work.
- 2.
Recall 1 Å= 10−10 m.
- 3.
3 Another version, developed in parallel by Heisenberg, consisted in the so-called matrix mechanics, which we will not treat.
- 4.
4 This second uncertainty relationship has a controversial status and its interpretion is a much thornier issue than the former’s. We will not enter this territory, and refer to classical textbooks as [Mes99] in this respect.
