My brief comment on ‘ The lecture № 3.’
=============.
Cornelius Lanczos wrote:
SRT was created on two postulates.
First postulate – there isn’t absolute speed of movement.
Every movement is relative.
Second postulate – the speed of light ( quantum of light)
is constant.
Lanczos wrote: from the first point of view it seems that
to unite these two different postulates is impossible,
trying to do this is absolute nonsense. (!)
But . . . . It was be done. (!)
. . It was needed the great Einstein’s courage to do this unite. (!)
How did Einstein connected them ? (!)
1
He solved this problem saying that Newton’s absolute space
and time are relative.
2
And these two postulates can be unite in spacetime- 4D.
3
As the result we can see different occurrences :
( for example: not only the physical parameters of particles
can change but space and time too )

And Lanczos wrote: now we are accustomed to this conception
and never, not for the world give up from such manner of thinking.
==================.
Very well.
There is only small problem in this conception:
What is 4D?
Nobody knows.
