Quantum reflections of a winter evening


A problem of interpretation?

December 14th, 1900 is known as the date of birth of quantum physics. In fact, that day Max Planck presented his report to the German Physical Society in Berlin, in which he argued that the exchange of energy in the phenomena of emission and absorption of electromagnetic radiation occurs in discrete form, not in continuous form as claimed by electromagnetic classic theory.

It was like opening a door to a new universe, that of subatomic particles. In a few decades it was learned that the basis of the strength of the real world around us (people, objects, plants, animals, etc.) is a joyful swarm of tiny particles distributed in clouds of probability, essentially surrounded by empty space. A shocking and apparently incomprehensible reality for the man of the ‘900: how could that still solid rock actually contain billions of microscopic “objects” in motion?

With the passing of the years, the road was covered deeper and deeper, revealing ever smaller particles for which new unknown names were coined: Leptons, Gluons, Quarks, Neutrinos, Fermions, Bosons, and so on until…
