E=mc² explains how energy and mass are linked. E is the energy in an object, while m is the mass, c is the speed of light. The equation would show that energy equals the mass multiplied by the speed of light, and multiplied by the speed of light again.
It could work out the amount of energy that can be released by something. It could tell us the amount of energy released from an atom bomb. The energy that could be released is strong enough to destroy and entire city.
When the World War 2 occurred, Albert found out that the Nazis had taken over Germany and that the German scientists were working on an atom bomb.
When Albert heard the news, he wrote a letter to the US President Franklin D. Roosevelt. He suggested that the US should also create an atom bomb.
The Manhattan Project had started creating the bomb. But Albert wasn’t part of the team that made the bomb because he wasn’t a nuclear physicist.
As soon as he found out how dangerous an atom bomb was, he wrote another letter to the President warning him about what the atom bomb could do. Although Albert wrote the letter for the President, Franklin died before reading it. Therefore the Manhattan Project continued.
Albert had heard an atom bomb was dropped onto Japan, and realised the US had already finished making the atom bomb. About 200, 000 people were killed or injured in Japan. After this, the Japanese surrendered and World War 2 ended.
Albert felt devastated about what had happened and called the first letter he wrote to the President, the greatest mistake of his life. After that, he worked very hard for world peace.
If Albert Einstein were alive today, I think he would continue trying to find the unified field theory. There are equations for theories of gravitation and electromagnetism. If Albert Einstein’s relativity theory and quantum theory was combined, it would be the theory of everything.
