课文背景（background）
Archimedes
Archimedes of Syracuse was a Greek mathematician, physicist, engineer, inventor, and astronomer. Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity. Generally considered the greatest mathematician of antiquity and one of the greatest of all time, Archimedes anticipated modern calculus and analysis by applying concepts of infinitesimals and the method of exhaustion to derive and rigorously prove a range of geometrical theorems, including the area of a circle, the surface area and volume of a sphere, and the area under a parabola.

阿基米德
阿基米德（公元前287年—公元前212年），伟大的古希腊哲学家、百科式科学家、数学家、物理学家、力学家，静态力学和流体静力学的奠基人，并且享有“力学之父”的美称，阿基米德和高斯、牛顿并列为世界三大数学家。阿基米德曾说过：“给我一个支点，我就能撬起整个地球。”
阿基米德确立了静力学和流体静力学的基本原理。给出许多求几何图形重心，包括由一抛物线和其网平行弦线所围成图形的重心的方法。阿基米德证明物体在液体中所受浮力等于它所排开液体的重量，这一结果后被称为阿基米德原理。他还给出正抛物旋转体浮在液体中平衡稳定的判据。阿基米德发明的机械有引水用的水螺旋，能牵动满载大船的杠杆滑轮机械，能说明日食，月食现象的地球-月球-太阳运行模型。但他认为机械发明比纯数学低级，因而没写这方面的著作。阿基米德还采用不断分割法求椭球体、旋转抛物体等的体积，这种方法已具有积分计算的雏形。

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.21cnjy.com
“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.www.21-cn-jy.com
“This problem seems difficult to solve. What should I do?” thought Archimedes.【来源：21·世纪·教育·网】
Archimedes was still thinking about this problem as he filled his bath with water. When he got into the bath, some water ran over.21·世纪*教育网
“That’s it!” shouted Archimedes. “I know how to solve the king’s problem!”2·1·c·n·j·y
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.21*cnjy*com
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.2-1-c-n-j-y
“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”【出处：21教育名师】
“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.21教育名师原创作品
