Quantum Mechanics demystified, a try
In order to be able to proceed acquainting on quantum mechanics and general relativity, it became evident one needs to be somewhat familiar with electromagnetism. Actually quite a lot.
That was my intuition from the beginning, but now it has turned out to be a necessity to carry on with. Thus, now familiarizing with electromagnetism as well.
A stable electric charge creates a static electric field around it, as described electricity. In practice, however, it is very seldom that charge is stable. Instead charges most always at least vibrate, unless they reach absolute zero temperature.
Also, if charged object is moving in steady speed, it creates a magnetic field around it.
If the charge, however, is accelerating, it will emit photons, i.e. creates electromagnetic radiation.
Electromagnetic radiation propagates as electromagnetic waves in space-time.
