During chapter twenty-two Albert Einstein was brought up during the topic of the atomic bomb. The bomb was a practical comprehension of relativity. This was the rethinking of the laws of physics by Einstein. Einstein showed that energy and matter were two forms of the same phenomenon which where his famous equation E=mc^2 came into play. This equation stated that energy in matter was equal to its mass times the speed of light squared. If I were able to meet one famous person it would certainly be Einstein. Albert Einstein is considered the most influential physicist of the 20th century. When Adolf Hitler came into power in the 1990’s, Einstein was visiting the United States. He was Jewish so he stayed in the U.S, and became an American citizen.
