Archimedes and the golden crown

One day in ancient Greece, King Hiero asked a crown maker to make him a golden crown. At first, he was very happy with it.

"It's a nice crown, isn't it?" he asked his men. Later, however, he began to doubt that it was a real golden crown. "Is it made completely of gold?" he wondered. He sent it to Archimedes and asked him to find out the truth.

"This problem seems difficult to solve. What should I do?" thought Archimedes.

Archimedes was still thinking about this problem as he filled his bath with water. When he got into the bath, some water ran over.

"That's it!" shouted Archimedes. "I know how to solve the king's problem!"

Archimedes went straight to the palace to see the king. First, he weighed the crown and asked the king for some gold of the same weight.

Next, he put two pots into two big bowls and filled both pots with water. He put the gold into one pot, and some water ran into the bowl. Then he put the crown into the other pot. This time, even more water ran into the bowl.

"Look at this," said Archimedes to King Hiero. "A crown made completely of gold displaces less water than a crown made of gold and another metal.

This crown displaced more water than gold of the same weight, so I'm certain that it's not completely made of gold."

"The crown maker tricked me, didn't he? What a bad man he is! "shouted King Hiero. He then sent the crown maker to prison.

阿基米德与金冠

古希腊的一天，希罗国王请一位王冠制造商为他制作一顶金王冠。起初，他对此很满意。

“这是一顶漂亮的王冠，不是吗？”他问手下。然而，后来他开始怀疑这是一顶真正的金冠。“它完全是金子做的吗？”他想知道。他把它寄给阿基米德，让他找出真相。

“这个问题似乎很难解决。我该怎么办？”阿基米德想。

阿基米德在洗澡时仍在思考这个问题。当他进入浴缸时，一些水溢了出来。

“就是这样！”阿基米德喊道。“我知道如何解决国王的问题！”

阿基米德直奔宫殿去见国王。首先，他称了一下王冠，向国王要了一些同样重量的金子。

接下来，他把两个罐子放进两个大碗里，把两个罐都装满水。他把金子放进一个锅里，一些水流到碗里。然后他把皇冠放进另一个锅里。这一次，更多的水流入碗中。

“看看这个，”阿基米德对希罗国王说。“完全由黄金制成的王冠比由黄金和其他金属制成的王冠能排出更少的水。

这个皇冠比同等重量的黄金置换了更多的水，所以我确信它不是完全由黄金制成的。”

“皇冠制造者骗了我，不是吗？他真是个坏人！”希罗国王喊道。然后，他把这位王储送进了监狱。
