The mass-energy of the electron is in the rotation?

›
For a photon, its energy is purely kinetic energy. If we try to stop a photon, its energy drops to zero. The electron has a mass and it rota...

The electron is a vortex?

›
Let us consider waves in water. If we disturb the surface of water and put energy into it, we usually create waves. The energy of a wave mov...

A rotating electric quadrupole produces spin 2 photons?

›
Suppose that we have a rod and two equal electric charges attached to its ends. We rotate the rod around the axis at its middle. An electrom...

The spin of a scalar field is 0, after all

›
Let us analyze in more detail what happens when we rotate a symmetric device which disturbs a scalar field. The device is assumed symmetric ...

Waves in a scalar Klein-Gordon field are longitudinal, in a sense

›
In our July 5, 2022 blog post we suggested that no field can have a quantum whose spin or helicity is 0. That is, a quantum of the field can...

The Higgs field, gauge transformations, and the Coulomb gauge

›
The Coulomb gauge is the "natural" way to define the scalar potential and the vector potential around electric charges. Let use de...
