Abstract
It the last chapter, we learned that the electromagnetic interaction between particles occurs through momentum exchange. Classically, this exchange is due to a field: a particle is a source of one or more fields through which it modifies the properties of the surrounding space. A second particle within the range of the first particle field and which generates the same field is subject to a force. Due to the field created by the second particle, the first particle “feels” the same force but in the opposite direction (third principle of dynamics). A field can only be measured through its effects on another source of the same field.

Notes
- 1.
Recent experimental results on neutrino oscillations demonstrate that neutrinos have a very small, but nonzero, mass (Sect. 12.6).
- 2.
For the family lepton number, this is not completely true since the discovery of neutrino oscillations, Chap. 12.
