Chapter 3 Basic quantum statistical mechanics of spin
... The fact that a quantum-mechanical spin has a fixed “magnitude” in the sense of (3.2) is the reason why it is typical to consider only classical spins of fixed magnitude. In fact, a classical fixed-magnitude spin can be recovered simply by taking the limit s → ∞ and ~ → 0 with s~ fixed. Taking ~ → 0 ...

Hydrogen atom
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.In everyday life on Earth, isolated hydrogen atoms (usually called ""atomic hydrogen"" or, more precisely, ""monatomic hydrogen"") are extremely rare. Instead, hydrogen tends to combine with other atoms in compounds, or with itself to form ordinary (diatomic) hydrogen gas, H2. ""Atomic hydrogen"" and ""hydrogen atom"" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
