Hey....Come back again...This post will show you all about E=mc2…
What you think when you see this equation, E=mc2….I think you must imagine Einstein’s…
Let me explain about this equation...
E=mc2 refer to the mass energy relationship….
E = energy (Joule)
m = mass (Kg)
c = speed of light (3 x 108 m/s)
This equation derived by the twentieth-century physicist Albert Einstein. Einstein was the first scientist who proposed the formula E=mc2 and the first to interpret the mass-energy equivalence as the fundamental principle that follows from the symmetry of relativistic space and time.
This equation may be validly used in two situations. First, when the mass is the rest mass, it called rest energy formula. But, if the mass is the relativistic mass, the energy come total energy.
The equation, E=mc2 shows that energy is always mass exhibits any form of energy needs. This formula is dimensionally consistent and does not depend on any specific system of measurement units.
E=mc2 sometimes been used as an explanation for the origin of energy in nuclear processes. Chemical reactions create nuclear energy that involve the splitting or merging the atoms of nuclei together. Termed fission is the process of splitting an atom's nucleus and termed merging is the process of merging the nuclei. To convert nuclear masses into energy, we can used this equation E=mc2... (E = amount of energy released, m = mass of nuclei, c = value of the speed of light)

Sory, can u give me specified question...
hello,
there are 2 questions that i want to ask you.
1)is E=mc2 relativity or special relativity?
2)what happen to the matters that seems to dissapear during a nuclear reaction?
thanks.

hello...
yeah..einstein is very2 weird and clever people i ever know in this world..his theories very simple and fundamental to all concepts of physics..
about thee e=mc2 theory,i can conclude that energy can be created using a small particle..we can see nuclear energy using e=mc2 formula to calculate the amount energy generated inside the power plant.as we know,atomic substance is very light but the energy generated very large.This shows that if we can achieve the speed of light,the energy generated very large..
correct me if i'm wrong becouse i also like you all..stil in learning process..@_@
so,here my question:
is it possible we can create a machine that can achieve speed of light?how about the state at that time?is it solid?water?gas?
thanx..

TQ to rebo..good questions...
1. E = mc2 equation is a direct result of the theory of special relativity..
2. In a nuclear reaction, the matter does go away. The special of nuclear reactions is, they change matter into energy, which is why nuclear power is so powerful. Einstein said E=mc^2, and c is a constant (speed of light,) so basically E (an amount of energy) is directly proportional to m (a quantity of mass.) In addition, mass and energy are interchangeable. Unlike any other sort of energy-producing reaction, a nuclear one not only tears apart the nuclei of atoms, some matter becomes converted to energy instead of just releasing stored energy like normal.
hi,
my question is:
what happens to the energy that is lost during this generation of power using nuke? and is there a way to capture this lost energy?

to danial...tq very much to that question...
in my opinion, why not we can create a machine such like that...it's not possible...but, this time we don't have machine like that...
about state at that time, we cannot say what happen because anything can happen...
p/s: speed of light = 300000 m/s = 1.0800e+6 km/h
Interesting. Based on our current understanding of physics, it is not possible to accelerate matters faster than (or exactly as fast as) light. If you can disprove this understanding, you are worth a Nobel Prize.
hahah...maybe "ONE DAY" sir...maybe danial can be a Nobel Prize...heheheh...
The equation E = mc2 indicates that energy always exhibits mass in whatever form the energy takes. Mass–energy equivalence also means that mass conservation becomes a restatement, or requirement, of the law of energy conservation, which is the first law of thermodynamics. Mass–energy equivalence does not imply that mass may be ″converted″ to energy, and indeed implies the opposite. Modern theory holds that neither mass nor energy may be destroyed, but only moved from one location to another.

This equation derived by the twentieth-century physicist Albert Einstein.Wow i am really amassed of his talent.till now the equation is valid even for this nuclear reactor providing with some modification.But the point is this genius can predict it long time ago. ..( VIMALAN A/l GENASAN vimalan_12@yahoo.com )
