Why does E=mc^2? (The book by Brian Cox and co.)

#1  Postby Joe09 » Sep 24, 2011 8:58 am

On reading the thread about Brian Cox, new book i saw that Ani was considered starting a thread on Brian's previous book so that he could ask questions.

Well it reminded me that I had a question so ive jumped the gun and started the thread myself, sorry Ani :lol:


Anyway, first question of the day is, where can i find the master equation? I clearly fail at internet searching because i cant find the master equation in a form as simplistic as the one stated in E=mc2.

Thankyou

Sorry for not using a comma correctly knowing what a grammar Nazi I am? :nono:

E=mc2 is the case where a particle has no momentum. See here: http://en.wikipedia.org/wiki/Mass%E2%80 ... D_mc.C2.B2

English and grammer have never been something i cared about

Which is probably why the marks i lose in my 'research papers' are mostly grammatical and not due to factual or procedural error

Apologies, i should have been clearer. I am talking about the book not the question itself.

The classical KE drops out of the equations;

Looks fascinating as does his upcoming (follow-on) book:

When Cox is talking about the master equation, he isn't talking about E=mc2, which is the simple form of the equation dealing with the relationship between energy and mass. He's talking about the master equation of the standard model.

I loved that book! The explanation of spacetime, and momentum through spacetime, with the speed of light being 100% of momentum being directed into moving through space made a lot of sense.
