It is said that E=mc with a little 2 just above the "c" indicating that something is squared. My question is, what is squared? Is the result of the multiplication of "m" and "c" squared or is the c squared first and then multiplied by m?

Just the c - it's E= m x c x c.

Thanks. Not that I really needed to know that in order to solve any equation I'm working on (as I'm not working on any) but the question did pop into my head when I was looking closely at the problem. I had an epiphany on the Theory of Relativity a few minutes ago that made some things more clear to me but then I hit some roadblocks on other aspects. My mind is touch and go these days. One minute it's thinking and the next minute I'm in "couch potato" mode.

uwot is right, when you think about the relationship bet matter/mass and energy, it makes since - and constant ratio bet matter and energy - a trillion to one - lest say.

IF the equation were E=(MC)2 - then when there is a "big body of mass" then the its equivalent energy would be less then if it were as small partical (the mass of the body in question would be squared) - and so the "c" part would take a smaller part in the eqaution for the big mass than the small tiny partical - and so making atoms "different" - having less "energy" if sitting in a large body, than if in a small partical.


make sense?

that is an excellent question BTW

thinking about stuff is good. too many don't sadly ;-/.

sure, i always welcome discussion about "stuff"

I'll never get this, and I've even read Woit's excellent book about it.

The speed of light is one light year per year. So E=M.

No?

Thanks, but I'm not really interested. I shouldn't have posted.

E=mc^2 can be in a ''rest''- potential state
E=mc^2 can be in active state (destroyed Hiroshima and Nagasaki)
according to Einstein's E=mc^2 is responsible for “inertial” movement
''DOES THE INERTIA OF A BODY DEPEND UPON ITS ENERGY-CONTENT?''
/ Einstein, 1905 /
according to Dirac E= ± mc^2 has dualistic nature

This is because 'you' are NOT Truly OPEN.

By the way, there is NO "my mind".

What do you mean by me not being "truly open"?

What Age means by, "truly open," is what is sometimes called an, "open mind."
An, "open mind," is like a open sewer into which just anything can be dumped and it has to accept it.
A, "closed mind," doesn't accept anything.
A, "descriminating mind," has a gate on it that does not allow anything in that cannot pass the test, "no contradictions allowed."

Age wants everyone to have an open mind into which he can dump all his contradictory crap.

Hope this helps.
