The formula E=Mc^2 continues to providethe answers to Physics.
1.
Photon is some " form of energy".
2.
Like a " form of energy" it has the rest energy: E=Mc^2.
3.
This photon has a mass.
But in many books it is written:
“…remember that this (photon,s)energy has mass
in accondance with the equation: M=E/c^2
(mass equal to energy divided by speed squared).
It is not correct.
Why?
Because SRT shows that mass and energy are equivalent:
the property called mass is simple concentrated energy.
In other words massof photon is its energy, and its energy
is its mass, and the distinctionis a simple play of words.
So, the mass of photon is: M=Ec^2 (mass equal to its
potential (rest) energy multiplied (not divided)
by speed squared).
So, it seems we are in some " fairy ring”:
E=Mc^2 and M= Ec^2.
When the question is:
How does this potential (rest)energy/mass of one photon
become kinetic and active?
Or in another words:
What does the Law of transformation and conservation
energy/mass mean according to one single photon?
The formula E=Mc^2 continues to providethe answers to Physics.
Why? Because:
1.
Classic physics says the energy and mass are two different
parametres of particle.
2.
SRT/QT says mass and energy are equivalent parametres
of particle.
Which theory is correct?
The both theories are correct, because every of them
observes and explains different particles.
SRT/QT explains behaviour of photon/electron, and
Classic physics observes all another particles (objects).
3.
The formula E=Mc^2 belongs to some particle.
My opinion about this formula is:
It is not importent how you call this particle.
You want, call it "energy " or "mass ".
You want, call it "daimonis "(like Socrates),
or "idea "(like Plato), or "thing in itself " (like Kant),
or "monada " (like Leibniz), or “dear friend” (like in Vedas),
or “soul” (like in religion), or "photon " (like in science).
One thing is only importent, that this particle has potential
(rest)power: c^2.But this particle cannot be at rest all the time.
Some time it must be active. How can it be active?
1.
Using one of its inner impulse (Planck,s)the particle
moves straight with speed c=1 (it is a corpuscular, which
doesn,t make waves).
2.
Using another of its inner impulse (Goudsmit/Ulenbeck)
the particle turns around its diametr and created waves.
And then we can call it an “electron” or “tachyon”.
But if you want you can call it “my dog”.
It is not importent. It is importent that this “dog”
or “soul” saves you, and is importent that you also
pay attention to “your dear friend”.
