A video to help explain what E=mc2 means.
Some more information
For all the Sheldon Coopers out there.
using a meme to look at this
E = mc2. It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing. Under the right conditions, energy can become mass, and vice versa. We humans don't see them that way—how can a beam of light and a walnut, say, be different forms of the same thing?—but Nature does.
So why would you have to multiply the mass of that walnut by the speed of light to determine how much energy is bound up inside it? The reason is that whenever you convert part of a walnut or any other piece of matter to pure energy, the resulting energy is by definition moving at the speed of light. Pure energy is electromagnetic radiation—whether light or X-rays or whatever—and electromagnetic radiation travels at a constant speed of 300,000 km/sec (186,000 miles/sec).
Why, then, do you have to square the speed of light? It has to do with the nature of energy. When something is moving four times as fast as something else, it doesn't have four times the energy but rather 16 times the energy—in other words, that figure is squared. So the speed of light squared is the conversion factor that decides just how much energy lies within a walnut or any other chunk of matter. And because the speed of light squared is a huge number—90,000,000,000 (km/sec)2—the amount of energy bound up into even the smallest mass is truly mind-boggling.
Here's an example. If you could turn every one of the atoms in a paper clip into pure energy—leaving no mass whatsoever—the paper clip would yield 18 kilotons of TNT. That's roughly the size of the bomb that destroyed Hiroshima in 1945. On Earth, however, there is no practical way to convert a paper clip or any other object entirely to energy. It would require temperatures and pressures greater than those at the core of our sun.

The sculptures found on Easter Island has amazed since they were first discovered. Moai or Mo‘ai, are monolithic human figures carved by the Rapa Nui people on Easter Island in eastern Polynesia between the years 1250 and 1500 CE. The tallest was almost 10 meters (33 ft) high and weighed 82 tons. To sculpt and move these works was a creative wonder of the ancient world.
Excavations show the size of these statues.
Designed by Tom Frantzen, the art piece is located in Brussels Belgium. It was created in 1985.The art piece is of a policeman being tripped from a man coming out of a sewer.
Chong Fah Cheong is a Singaporean sculptor and is identified with a series of figurative sculptures depicting the life of people living and working along the Singapore River.
The monument symbolizes the enslavement of people by communism in Poland and for those living "underground" during the revolt for freedom.
Melbourne sculptor Charles Robb turned Victoria's first lieutenant-governor, Charles La Trobe, on his head, says it embodies the notion that universities should turn ideas on their heads. The statue of Charles La Trobe is located at La Trobe University in Bundoora, Australia.
Also known as the Freedom Sculpture.
Klaus Weber, a fountain sculptor, created an installation of stone sculptures entitled ‘The Big Giving’ on the South Bank in central London.
This is the work named “What You see Might Not Be Real” and displayed in a latest art exhibition in a Beijing art gallery. Chinese artist Chen Wenling made it to dig at the global financial crisis. The strong and farting bull represents Wall Street (in Chinese slang, to fart mean to bluff or lie). And the man being shoved into the wall is Bernard Madoff who was sentenced to 150 years in prison because of Ponzi schemer.
The 40-foot-high bear, which injects a welcome sense of fun and playfulness into the convention center experience, is the creation of local artist Lawrence Argent.
‘The Silent Evolution’ made by Jason de Caires Taylor. It is resembling a lost city and biggest and most renowned submerged gallery. Forbes Corporation voted this spot as a standout among the most remarkable place on the planet.
Hollow Men are made by Bruno Catalano.
A public sculpture in the Fremont neighborhood of Seattle, Washington in the United States.
Yes, it is what you think it is.

Hamburg, Germany just welcomed “Die Badende” (“The Bather”), a giant sculpture by artist Oliver Voss resting in Binnenalster Lake.

1. Pick a number from 2 to 9. It can be 2 or it can be 9, or any number in between.
.
.
.
.
.
2. Take that number that you've chosen, and multiply it by 9.
.
.
.
.
.3. That should give you a two digit number. Take those two digits and add them together.
.
.
.
.
.
4. Take the resulting number and subtract 5 from it.
.
.
.
.
.
5. Take that number and correspond it to the alphabet, numbering the letters. A =1, B=2, C=3, and so on...
