Einstein was born in 1879 in Germany. As a child, he was slow to learn to talk. As a pupil, he was backward. But when he was fourteen years old, he became clever. He taught himself maths from textbooks. He studied hard because he wanted to be a physicist.

In 1901, Einstein began teaching. In 1902 he continued his studies at the University of Zurich. Several years later, he formulated(系统地阐述)his famous Theory of Relativity(相对论).To most people the law of relativity is difficult to explain. But once Einstein explained it to a group of young students. He said,” When you sit with a good girl for two hours, you think it is only a minute. But when you sit on a hot stove for a minute, you think it's two hours. That is relativity."
