Albert Einstein & Isaac Newton
Newton discovered many of the laws and theories that not only furthered our understanding of the universe, but also gave future scientists the tools to discover how to enter space. He discovered gravitational force and established the three Universal Laws of Motion. By tying these discoveries to the work Johannes Kepler and his Laws of Planetary motion, he established classic mechanics the beginning of modern Physics. This was huge in many ways as he proved definitively the heliocentric model first proposed by Copernicus. He also was the first to propose a set of laws that described the motion of all things in the universe. This served as the basis for our understanding how the universe functions and why it is the way it is. For his time and even now this was a major breakthrough.
Einstein created many theories which proved that things like gravity , light, energy and matter were connected with each other. At first, very few scientists could understand Einstein’s theories but as time passed other scientists showed that he was correct. He lived in Berlin for a long time and there he developed many of his scientific theories. Einstein became so well known that he was invited to universities around the world to talk about his discoveries . In 1921 he received the Nobel Prize for Physics. In the meantime things were starting to change in Germany. Einstein was against the Nazis and their ideas of controlling the world and killing Jews. The Nazis, in return, hated him and his theories and they burned most of his books. Einstein decided to leave Germany and go to the United States. When World War II broke out in 1939 Einstein discovered that German scientists were working on a bomb that could kill thousands of people. He wrote a letter to the American president to warn him and suggested that the Americans start building one too. One of the most famous equations ever written came from Albert Einstein : E = mc 2 . Energy is mass times the squared speed of light. This equation shows that mass can be turned to energy. Because the speed of light square is such a high number even a small amount of mass can be turned into a lot of energy.
Albert Einstein and Isaac Newton both made discoveries about gravity and they were both interested in the topic. But after a while Einstein started getting into the topic about atomic bombs and nuclear powers and what they can do. So they are alike but they still have a few differences.
