Step one Introduction 1.Warm-up questions: Give the students the following topics to discuss and then ask them to answer these questions (1)Was Einstein bright in his early childhood?Give examples. (2)What is his greatest contribution to the mankind? (3)What doyou know about the life of Einstein? (4)Do you think Einstein was responsible for the search work on the atomic bomb?Why? (5)Describe the appearance of Einstein. 2.Background Information (1)A Brief Introduction to Albert Einstein Albert Einstein,whose Special Theory of Relativity and General Theory of Relativity revolutionized scientific perceptions of the universe,is acknowledged along with Newton,as one of history's greatest physicists. Son of free-thinking,cultured Jews,Einstein was unable to speak until he was three and displayed no special promise.Anti-Semitism also hampered his talent when it began to emerge.He became a Swiss citizen in 1901,obtaining a doctorate from the University of Bern in 1905.His research,which ended in the famous equation E=me2, was published in the same year. After World War I,Einstein's fame extended beyond the scientific community and in 1921 he was awarded the Nobel Prize for physics.During the 1920s he regarded the rise of the Nazis in Germany with horror,eventually emigrating to the U.S.where,in 1933,he took up a post at Princeton University.In 1939 his early warnings of German scientific attempts to make an atomic bomb prompted the start of the Manhattan Project.
