F Albert Einstein had a great effect on science and history. An American university president once said that Einstein had made a new outlook, a new view of the universe. It may be some time before the average mind understands fully the identity of time and space and so on—but even ordinary man now understand that the universe is something larger than ever thought before.
By 1914 young Einstein had been world-famous. He accepted the offer to become a professor at the Prussian Academy of Science in Berlin. He had few duties, little teaching and unlimited chances for study, but soon his peace and quiet life were broken by World War I.
Einstein hated fighting and killing. The great suffering of war affected him deeply, and he sat unhappily in his office doing little. He lost interest in his research. Only when peace came in 1918 was he able to get back to work. In the year following World War I honors were increasingly put on him. He became head of the Kaiser Whihem Institute of Theoretical Physics. But he himself refused the effort to put him in a position far above other people. He was well known for his humble（谦逊的）manners. He often said that his success would certainly have been achieved by others if he had never lived. In 1921 he won the Nobel Prize, and he was honored in Germany until the rise of Nazism when he was driven from Germany because he was a Jew.
