    Famous scientist Albert Einstein died in 1955.His brain（大脑）now is in the central state of Kansas of the United States.It belongs to retired medical Thomas Harvey.How did this happen?And why?

    The story began in the 1950s.Albert Einstein and Thomas Harbey knew each other when both lived in the Princeton Hospital. When Einstein died,Doctor Harvey was called on to examine his body.It was then that he started to study what had become a long time examination of Einstein\’s brain.His goal was to discover some physical evidence(证据)of the scientist\’s genius(天才).

    Doctor Harvey, however,did not tell Einstein\’s family that he kept the great man\’s brain.It was only later that the family learned of Doctor Harvey\’s work.They did not like the idea at first. After Doctor Harvey explain his idea to them, they agreed to permit him to study the brain.

    Doctor Harvey then asked two other scientists to help. They cut the brain into 3pieces. They marked each piece before placing it in containers with chemical formaldehyde (甲醛) to protect it. They also prepared several extremely tiny pieces of the brain for study. Doctor Harvey has been studying Einstein\’s brain since then. He has carried it with him as he moved from job to job and form place to place. He has also lent parts of the brain to other scientists for study.

    Only one researcher has found something. A doctor at the University of California found that the left part of Einstein\’s brain has more cells (细胞) than normal (正常标准). Such cells are known to feed the brain. She said this may mean that the cells could affect (影响) intelligence (智力). Doctor Harvey says he does not think Einstein would mind the research. After all Einstein was scientist.
