In special theory of relativity how is the relational bit happen?

"In the theory of relativity only time is taken as constant. "

No, the speed of light in vacuum is constant, no matter how or where you look at it.

If I have speed relative to you, we still see the same light beam travelling at the same speed, no matter our relative velocities.

That means that our perception of space and time must change in order for the speed of light to remain constant.

Pythagoras' theory applies equally to the largest and smallest triangle.

So mathematicians had decided, that this applies also to

the electromagnetic phenomena;

that the laws of a nature in the macrocosm and in a microcosm are identical.

It appears that this is not so.

In the macrocosm, Maxwell's laws apply

and in the microcosm, other laws, the laws of SRT operate.

These laws are interconnected.

SRT is a continuation of the development of electrodynamics.

1)What is the make up of the electron in Maxwell's theory?

Maxwell's equations have no relation to the movement of the electron.

They describe the distribution of electromagnetic waves

but not the movement of a particle such as an electron.

In Maxwell's theory, the charge - electron is considered local,

as though the particle is "at rest".

This means that it particle does not move rectilinearly,

but rotates around the diameter (has the form of a sphere).

The rotation of the electron creates electrical waves.

2) What is the make up of the electron in SRT?

At the beginning of the last century many scientists

(Einstein, Lorents, Fitzgerald, Poincare, Abraham) were interested in the question:

What will take place, if the electron (Maxwell's) , creating an electrical field,

begins to move - rectilinearly?

All of them came to the conclusion that there would be radical changes with the electron.

These changes are described by the Lorentz transformations.

That is, when the originally rotating electron (sphere) begins to move rectilinearly,

during movement it gradually will change its geometrical form.

Having reached constant speed of c=1, its form will become a circle.

In such condition it is called a "quantum of light ",” photon”.

And when a quantum of light rotates around its diameter its name is “electron “

An "electron" is an actively working “quantum of light”.

With such an interpretation, electrodynamics and SRT become one general theory.

In the theory of relativity only time is taken as constant. Mass, volume are taken as variables. Give me more details about exactly what you want

i have no idea
