英国人卡文迪许(1731-1810)是有史以来最伟大的实验科学家之一。他在力学、热学、电学、化学等领域都有划时代的贡献。100多年前,卡文迪许就用自己设计的扭秤做实验———后人称为著名的卡文迪许实验,证实了万有引力定律,推算了地球的平均密度是水的密度的5.481倍(现在的数值是
The English Cavendish (1731-1810) is one of the greatest experimental scientists ever. He has epoch-making contributions in the fields of mechanics, thermal science, electricity and chemistry. More than 100 years ago, Cavendish experimented with his own designed torsion scales - the so-called famous Cavendish experiment, which confirmed the law of universal gravitation and deduced that the average density of the earth is 5.481 times the density of water (The current value is
