What does E=mc2 mean?

Download your FREE infographic here http://www.emmalouiseosborne.com/Shop... In this video, I explain what Einstein's equation E=mc^2 means and why this discovery became one of the most famous equations in the world. Transcript: E=mc^2 is one of the most famous equations in the world, but what does it actually mean? This equation tells us that energy and mass are the same thing. They are related to each other by a constant and that constant happens to be the speed of light squared. Light travels at 300 million metres per second. If we take one kilogram of mass we get 9 times 10 to the 16 joules of energy out, which is 9 with sixteen zeros after it. That's an incredibly huge amount of energy. In fact it's enough energy to power the United Kingdom for one whole year. It was this discovery that gave birth to the quest for nuclear energy.
