Albert Einstein
/ˌælbət ˈeɪnsteɪn/
/ˌælbərt ˈeɪnsteɪn/
- (1879-1955) a physicist, born in Germany, who was possibly the greatest scientist of the 20th century. In 1905 he published his theory of relativity. This led to the equation giving the relationship between mass and energy, E=mc2, which is the basis of atomic energy. Einstein suggested how it could be used for making weapons, but after the Second World War he spoke publicly against nuclear weapons. By 1917, he had become famous all over the world. He was given the Nobel Prize for physics in 1921. When Hitler came to power, Einstein, who was Jewish, went to live in the US, becoming a US citizen in 1940. In 1933 he wrote a book called Why War?with Sigmund Freud. He became a professor at Princeton University in 1934, and he spent the rest of his life looking, without success, for a theory that combined those of gravitation and electromagnetism. In 1952 he was offered the presidency (= the position of president) of the state of Israel, but did not accept it.
阿尔伯特·爱因斯坦（1879-1955）是物理学家，出生于德国，可能是20世纪最伟大的科学家。1905年，他发表了相对论。这导致方程式给出了质量与能量之间的关系，E = mc2，这是原子能的基础。爱因斯坦提出了如何将其用于制造武器的建议，但是在第二次世界大战之后，他公开发表了反对核武器的演讲。到1917年，他已享誉全球。他于1921年获得诺贝尔物理学奖。希特勒上台后，犹太人爱因斯坦去美国居住，并于1940年成为美国公民。1933年，他与西格蒙德·弗洛伊德（Sigmund Freud）一起写了《为什么要战？》一书。 。他于1934年成为普林斯顿大学的教授，一生都在寻找成功，结合了引力和电磁学的理论。1952年，他获得了以色列国的总统职位（总统职位），但没有接受。
