* <Stern-Gerlach experiment>
* <fine structure> split in energy levels
* <anomalous Zeeman effect>
* of a more statistical nature, but therefore also macroscopic and more dramatically observable:
  * <ferromagnetism>
  * <Bose-Einstein statistics> vs <Fermi-Dirac statistics>. A notable example is the difference in <superfluid> transition <temperature> between <superfluid helium-3> and <superfluid helium-4>.
