An ‘unknown’ electron.
==========================.
1900, 1905
Planck and Einstein found the energy of electron: E=h*f.
1916
Sommerfeld found the formula of electron : e^2=ah*c,
it means: e= ah*c and e= -ah*c.
1928
Dirac found two more formulas of electron’s energy:
E=Mc^2 and -E=Mc^2.
Question.
Why does electron heed five ( 5 ) formulas ?
=========================.
Why does electron obey three Laws ?
a) The Law of conservation and transformation energy/ mass
b) The Heisenberg Uncertainty Principle / Law
c) The Pauli Exclusion Principle/ Law
================================.
#
Now nobody knows what the Electron is.
1
You know, it would be sufficient to really understand the electron.
/ Albert Einstein /
2
Tell me what an electron is and I'll then tell you everything.
/ Somebody /
3.
In the internet we can read hundreds theories of electron.
All of them are problematical.
Nobody knows what electron is.
#
For example.
More than ten different models of the electron are presented here. (!!!)
More than twenty models are discussed briefly. (!!!)
Thus, the book gives a complete picture of contemporary theoretical
thinking (traditional and new) about the physics of the electron.

====================.
So, why do physicists call an electron a simple
elementary particle if IT looks not very simple ?
=====================.
We know the electron is very important particle in our live.
It acts in Maxwell’s electrodynamics.
It acts in the atom.
But how electron acts in cell and in Outer space we don’t know.
We need time to understand this fact.

Schrodinger's cat meets Dirac’s electron.

Physics law says that no energy can be created or destroyed
but can be changed from one state to the another.
So, according to " The Law of Conservation and Transformation
of Energy/ Mass" Schrodinger's cat cannot die.
But also the S/cat cannot live for ever.
How to be?
It seems we have only one decision.
The Schrodinger's cat can change its image.
===.===========.

Until 1928 physicists knew the electron has energy: E=h*f.
And then Dirac discovered two more formulas of electron’s
energy: E=Mc^2 and -E=Mc^2.
The negative energy -E=Mc^2 means that the electron is dead.
But according to " The Law of Conservation and Transformation
of Energy/ Mass" this is impossible.

The positive energy E=h*f and E=Mc^2 means that the electron
is an active/ alive particle. But when electron interacts with vacuum
it explodes like ‘big bang’ and all its parameters become infinite.
But real particle ( as electron) cannot have infinite parameters.
How to be?
In my opinion we have only one decision to understand the situation.
Like the Schrodinger's cat Dirac’s electron can change its image.
The Single Electron can change its active/ alive energy into
dead / potential energy and vice versa according to
" The Law of Conservation and Transformation of Energy/ Mass"

The problem is we dont know what " The Law of Transformation
of Energy/ Mass" means for One Single Electron.
==========.
P.S.
Planck and Einstein found the energy of electron: E=h*f.
Sommerfeld found the formula of electron : e^2=ah*c,
it means: e= ah*c and e= -ah*c.
Dirac found two more formulas of electron’s energy:
E=Mc^2 and -E=Mc^2.
Question.
Why does electron heed five ( 5 ) formulas?

One professor asked a student:
“ What is an electron?”
“ Ah, God damn it! I have forgotten. And in fact even in the
morning I knew it. ”- the student answered.
“ You should recollect it without fail, - professor said –
because you were the unique person who knew, what
electron was, and you had suddenly forgotten!”
