阿基米德与王冠的故事
Archimedes was a wise man who lived in Greece long,long ago.He was so wise that even the king was his friend.
One day the king asked him,"How do you 1ike my new crown It's all gold." The king stopped."That is,I think it's all gold," he said,"I gave a man gold to make this crown.But I think he may have kept some of it.To make up for what he took,he may have added silver."
"You are a wise man," the king went on,"Find out if this crown is all gold.That way I will know if the man kept some of my gold."
Archimedes thought about the crown for a long time.Then,one day he had an idea.He thought of it as he stepped into his bath.He saw that the water ran out over the sides.
"Eureka!" he yelled.(That means "I've got it!" in Greek.) He hopped out of his bath.He ran all the way to the king's home.It is said that he did not even dress.
Why was he so excited Wel1,the bathwater showed him something.Now he knew how to tell if the crown was made only of gold.
Archimedes asked the king for a piece of gold." It must be the same size as the one you gave the man," he said.Then he filled a pan with water.In it he put the piece of gold.The water rose.He then took the gold out.He put the crown in the pan.The water rose even higher than before.That should not have happened!The crown and the piece of gold should have taken up the same space in the pan.Something had been added to the crown.It may have been silver.It may have been something else.But the crown was not a1l gold.
Archimedes's idea was so clever that it is still used today.And he went on to learn many other things.But he sometimes got his ideas in strange places.
(以下中文故事,不是上面英文的译文)
国王在前不久,叫一个工匠替他打造一顶金皇冠.国王给了工匠他所需要的数量的黄金.工匠的手艺非常高明,制做的皇冠精巧别致,而且重量跟当初国王所给的黄金一样重.可是,有人向国王报告说:“工匠制造皇冠时,私下吞没了一部分黄金,把同样重的银子掺了进去.”国王听后,也怀疑起来,就把阿基米德找来,要他想法测定,金皇冠里掺没掺银子,工匠是否私吞黄金了.这次,可把阿基米德难住了.他回到家里苦思苦想了好久,也没有想出办法,每天饭吃不下,觉睡不好,也不洗澡,象着了魔一样.
有一天,国王派人来催他进宫汇报.他妻子看他太脏了,就逼他去洗澡.他在澡堂洗澡的时候,脑子里还想着称量皇冠的难题.突然,他注意到,当他的身体在浴盆里沉下去的时候,就有一部分水从浴盆边溢出来.同时,他觉得入水愈深,则他的体量愈轻.于是,他立刻跳出浴盆,忘了穿衣服,就跑到人群的街上去了.一边跑,一边叫:“我想出来了,我想出来了,解决皇冠的办法找到啦!”
他进皇宫后,对国王说:“请允许我先做一个实验,才能把结果报告给你.”国王同意了.阿基米德将与皇冠一样重的金子、一块银子和皇冠,分别一一放在水盆里,看金块排出的水量比银块排出的水量少,而皇冠排出的水量比金块排出的水量多.
阿基米德对国王说:“皇冠掺了银子!”国王看了实验,没有弄明白,让阿基米德给解释一下.阿基米德说:“一公斤的木头和一公斤的铁比较,木头的体积大.如果分别把它们放入水中,体积大的木头排出的水量,比体积小的铁排出的水量多.我把这个道理用在金子、银子和皇冠上.因为金子的密度大,而银子的密度小,因此同样重的金子和银子,必然是银子的体积大于金子的体积.所 以同样重的金块和银块放入水中,那么金块排出的水量就比银块的水量少.刚才的实验表明,皇冠排出的水量比金块多,说明皇冠的密度比金块的密度小,这就证明皇冠不是用纯金制造的.”阿基米德有条理的讲述,使国王信服了.实验结果证明,那个工匠私吞了黄金.
阿基米德的这个实验,就是“静水力学”的胚胎.但他并不停留在这一点上,继续深入研究浮体的问题.结果发现了自然科学中的一个重要原理——阿基米德定律.即:把物体浸在一种液体中时,所排开的液体体积,等于物体所浸入的体积;维持浮体的浮力,跟浮体所排开的液体的重量相等.
