Question

Why is Einsteins e=mc2 equatio used

Answer 1

@quarkine

Answer 2

it is the mathematical form for the fact that mass can be converted to enegy...the same principle that was used to make bombs.it is widely used but heavily in nuclear physics...

Answer 3

well...then if a mass of 0.1g of radium is allowed to decay, does it mean energy equivalent to = 0.1*(3*10^8ms^-1) is released?

Answer 4

that would be a biiiiiigggggg value

Answer 5

yeah exactly!!...that is why a small bomb is able to cause such a huge destruction.
i don't think that spontaneous decay is accompanied by much mass-energy conversion.but fission does have significant conversion and hence is explosive..

Answer 6

oh alright..so what does particle physics deal with this equation

Answer 7

Einstein was awesome

Answer 8

well particle physics is very much overlaping with nuclear physics..so they must be both using this equation very much..but i dont know exactly how much it is used in particle physics...
