金冠之谜 赫农王让金匠替他做了一顶纯金的王冠,做好后,国王疑心工匠在金冠中掺了银子,但这顶金冠确与当初交给金匠的纯金一样重,到底工匠有没有捣鬼呢?既想检验真假,又不能破坏王冠,这个问题不仅难倒了国王,也使诸大臣们面面相觑.后来,国王将它交给了阿基米德.阿基米德冥思苦想出很多方法,但都失败了.有一天,他去澡堂洗澡,他一边坐进澡盆里,一边看到水往外溢,同时感到身体被轻轻拖起.他突然恍然大悟,跳出澡盆,连衣服都顾不得穿就直向王宫奔去,一路大声很着“尤里卡”,“尤里卡”(Fureka,我知道了)原来他想到,如果王冠放入水中后,排出的水量不等于同等重量的金子排出的水量,那肯定是掺了别的金属.这就是有名的浮力定律,既浸在液体中的物体受到向上的浮力,其大小等于物体所排出液体的重量.后来,该定律就被命名为阿基米德定律.The Mystery of Golden Delicious Joseph Wang farmers so that he has done a goldsmith for a crown of pure gold,well,the King of suspicion Jinguan craftsmen in the silver-doped,but the top Jinguan goldsmith to do with the first gold of the same weight,the craftsmen in the end there play a trick on them?Would like to test both true and false,and they do not damage the crown,this issue is not only deterred the king,but also all looked at each other ministers.Later,the king will give it to the Archimedes.Archimedes冥思苦想a lot,but have failed.One day,he went to Bath to bathe,he got into the bathtub,the side to see the water to spill,while the body is being gently拖起.He suddenly realized,out of bathtub,and even clothes to wear on the vertical gave the palace ran,shouting all the way is a "eureka","Eureka" (Fureka,I know) that he thought that if the crown Add water,the discharged water does not mean the same weight of gold from the water,then it must surely be the other metal-doped.This is the well-known law of buoyancy,both immersed in liquid in the upward by the buoyancy of objects,the size of objects from the weight of liquid.Later,the law was named Archimedes law.
