Overview

Why Does E=mc2?: (And Why Should We Care?) by Brian Cox, Jeff Forshaw

What does E=mc2 actually mean? Professors Brian Cox and Jeff Forshaw go on a journey to the frontier of twenty-first-century science to unpack Einstein's famous equation. Explaining and simplifying notions of energy, mass, and light-while exploding commonly held misconceptions-they demonstrate how the structure of nature itself is contained within this equation. Along the way, we visit the site of one of the largest scientific experiments ever conducted: the now-famous Large Hadron Collider, a gigantic particle accelerator capable of re-creating conditions that existed fractions of a second after the Big Bang.

A collaboration between one of the youngest professors in the United Kingdom and a distinguished popular physicist, Why Does E=mc2? is one of the most exciting and accessible explanations of the theory of relativity.

Either the equations are messed up or the symbols don't translate correctly in the electronic version. The authors say they are going to explain relativity using math no more complex than the pythagorean theorum and then claim it isn't a book about "maths" when they produce a result without explaining how they got there. At a minimum there should be an appendix showing the calculation. But that isn't the worst part. The authors add symbols without telling you what they are or where they came from. So, on p. 38, the square root of 1/ (c squared - ^ squared) becomes 1/ square root c squared ^ v squared. Huh? Where did v come from? Is it a variable, an operator, what? We don't know because the authors don't say. We know it doesn't mean velocity, because that's what ^ is defined as. Confusing enough, but then further down the same page, the square root c squared ^ v squared becomes ^squared/ c squared, again with no explanation. Thanks for the "maths" lesson guys.

They did an exceptional job of presenting this complex topic in down to earth language that explained it far better than any of my physics courses in college.

Yes, i DO care, but ppl are saying 'pray for all the lost souls'. Dont get me wrong, i totaly agree, but then OTHER ppl are saying 'shame to the bombers!' And 'i hope the bombers go to h**l!' But please do this: pray for the people of Boston as WELL as the ppl who set off te bombs. U need to forgive them because of the terrible things they did. They were probably innocent alchoholics or something who need to be forgiven. God always forgivs everyone.

I care A LOT, but as I've said a lot, it's not gun control we need, it's gun owner control. And we don't know if it was North Korea. And peopoe from all over the world come to the Boston marothon, so it's hard to tell who's responsible. I'm wearing purple today, beause I care. The best thing we can do is pray. Prayer is a strong thing. ~In God, ~Your fellow American

I care because two other tragic things happened this week. There was a shooting in Watertown, MA and some people shot down two MIT police officers. Also, some of my aunts friends and some of my dads collegues were at the finish lie and got hurt. I care because ive been mourning since New Years Eve about death. If you heard about the Watertown and MIT incidents put this symbol somewhere in your post: $. ~Rainbow Dash, Rainbowpaw, and Mintpaw /)(\
