As we know，Archimedes was a great scientist.He was one of the greatest minds in history.It is said that he once used a very large mirror，or a set of mirrors to set fire to Roman ships attacking his home city of Syracuse.He also helped King Hiero solve the problem of the golden crown easily without destroying it.He liked studying the world around and trying a lot to find out the truth.Here is a story about him.
One day，when he was walking in the street，he saw a thin girl getting a big bucket（圓桶）of water from a well without difficulty.He then watched and thought it over.After studying this for a long time，he got the famous conclusion -the law of the lever.He then said to the king， "Give me a place to stand and I will move the earth."The king didn't believe him and asked him to support his idea by pulling a huge warship into the river by himself.Archimedes first set up an operating crank（操作曲柄） by the bank.He then put a group of pulley blocks between it and the warship.Later he could pull the warship into the river by moving the operating crank.From then on，the king trusted him and asked everyone to trust him.
In fact，Archimedes just used some leverage（杠桿力） in this experiment.Besides this，he also made a lot of advanced weapons，which helped him protect his nation and his people in many wars.What a great scientist he was!
