@maxdancona,
No, you are being deceptive. Newtons physics was totally replaced by Einstein's Relativity. Newtons physics is mathematically wrong at any speed, but greatly at near light speed.
As we have computers now, there is no excuse to still be using Newtons inaccurate equations, when Einsteins are 100% correct.
I've works through all the courses available online from Yale, MIT, Harvard, Stanford, ans well as a bunch of Professors who have their own teaching channels.
ALL of them make the same errors when deriving the equations, so all of them come up with the same errors.
The ONLY way you can honestly end up with Special Relativity, is is you literally, "Shut up and calculate". Don't ask questions,, stop thinking critically, and just learn the material by Rote.
"Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality." (Nikola Tesla)
This is really the only way to end up with SR. By NOT asking the hard questions, by ONLY focusing on Math, which is itself based on incorrect understanding of Physics.
Its telling that we have come this far, but you still have not attempted to explain what I originally asked.
Why is that? You keep ducking and dodging. You think I have a lack of understanding, but this should not prevent you from providing an explanation. Others are reading this, they cant be as thick as I am. Do it for their benefit.
