Huh? What is it with you people? It is NOT discourteous IN THE LEAST
to tell someone that they lack the math background needed to study
physics (beyond the secondary school level).

I made no judgment about the person's character. I gave no insult.
I simply said that he lacks the math to study relativity and
I gave some elementary examples of the kinds of math that one needs to
know.

BTW are you aware that simultanaity is not an absolute feature
of events in different places?

PS the CAPS or SHIFT key is on the left.

basically I don't know which one is accurate as i don't see the formula from one in the other so i don't know which is better for me to start at I stopped taking physics on teacher suggestion because i kept on losing my homework/ forgetting to do it. we got as far as d=v_it + .5*a*t^2 but I'm willing to learn more.

I think Einstein needed a tip off about Riemann before he
fully formulated and published GR.
The point is that the "notion" of relativity is a strong incentive
to study the maths you cited.

You should have said "the dog ate it".

not sure if i had a dog at the time and cats don't eat homework they eat hair leading to trichobezoars lol.

This book: http://www.amazon.com/Einstein-Begin.../dp/0679725105
is a good place to start, but Bob S. is correct that you need a lot of mathematical background to really understand relativity, especially general relativity.

I don't own credit cards and strapped for cash I just don't think some days when i post here and as you all know I can use google just don't know the best sources lol.

You could always try your local library.

can you give me a good online source since nobody answered which is accurate ?

Specifically, Einstein needed to learn about metric curvature tensors
(e.g. the Ricci tensor to name one) on Riemann surfaces. This is most
definitely NOT an elementary topic.

okay I want a site on the basics i can try and look up from there.
