Albert Einstein, one of the great scientists the world has ever seen, has revolutionized the history of science. His greatest contribution is the theory of relativity.
One equation from the theory is e=mc. In this formula, ‘E’ stands for energy, ‘m’ for mass, and ‘c’ is the speed of light, which is a constant, and assumed to be the fastest speed possible in the universe. This formula explains how energy is related to mass. It states that energy and matter are interchangeable. He published the special theory of relativity in 1905, and the general theory of relativity in 1916.
This theory changed much of the way scientist look at the world, and set the found for many modern areas of science including nuclear energy.
