e=mc^2

Rest Energy=Rest Mass*Speed of Light (3.0*10^8m/s)^2

Derived by Einstein and is the fundamental equation that explains mass->energy conversion.

e=mc^2 isn't meant to creat the a. bomb, but mankind is just too stupid to use it for good.

E=mc2

E=mc2 is an incorrect format to write Einsteins equation for the theory of special relativity. The correct way to write the equation when the hypertext capability is not possible is to use ^2. Thus, the correct way to write the equation is E=mc^2. (ESMC)

E=mc^2 not E=mc2

(_E=MC2_) 

Is an emoticon that means smartass. Often used in IRC.

Oh Gus, u r a fking (_E=MC2_)

e=mc2

Albert Einstein's forumla for his theory of general relativity.

E is Energy
m is Mass
c2 is really c squared (c^2). This means the velocity of light (8.0 x 10^8 meters/second)

By using this, it shows that no mass can accelerate to the speed of light.

E=MC² 

The only definition on Urban Dictionary with the actual ². It basically means Energy=Mass X Speed of light squared. Simple, eh?

Wow! Somebody knows how to do the ² in E=MC²!

e=mc2

How idiots write E=MC^2.

The ^ signals "to the power of," which in the case of two we shorten to "squared."

E=mc^3

Forget about E=mc^2. Be more powerful with E=mc^2

Person 1: Hey do you know what E=mc^2 means
Person 2: E=mc^2? What are you trying to do lift a feather. No be more powerful with E=mc^3
