Let's see if that's the only difference.Jeronimus said:You do see that the only difference wikipedia has is naming l, L0, and l' L. I want to believe that standards do not go that far as in telling you what kind of letters to use for the size of lengths as long as you remain within "some" boundaries.
Gamma is not really different from what i arrived at. It's not "inverse" as you say. You thought it is because i use different letters for the length in system A than what wiki did.
Your equation is:
l*gamma = l'
Now we change l to L0 and l' to L:
L0*gamma = L
Wiki says:
L = L0/gamma
Can't you see that your gamma is the inverse of the wiki gamma?
Then you also defined your gamma as:
gamma = sqrt(1 - (v^2/c^2))
But wiki says the inverse of that.
I wouldn't say it's a standard, it's just conventional. I'll take that bet. But you have to do the search. If you can find a book within 24 hours that switches the numbering of Einstein's postulates, I'll give you a dollar. No help from anybody else, please.Jeronimus said:Furthermore, we are talking about just two postulates here. TWO. About SR. I sincerely doubt that there is a "standard" for which to name first and which to name second. I would even place a high bet that somewhere out there, there is SOME book by some known scientist who dared to switch the numbering on those two postulates. God forbid.
