henry cavendish（1731－1810），the eccentric englishchemist and physicist，had no appropriate instruments for thepurpose，so he measured the strength of an electrical current in adirect way.he shocked himself with the current of the chargeand estimated the pain（he managed to live to nearly eighty）。
henry cavendish was painfully shy and could barely speak toone person—never to two.he was so afraid（or so shy，orsomething）in the presence of women that he communicated withhis female servants by notes only.if one crossed his path in hishouse，she was fired on the spot.he built a separate entrance tohis house so he could come and go without meeting anyone.inthe end he insisted on dying alone.
亨利·卡文迪什（1731－1810），是个脾气古怪的英国化学家和物理学家。他没有合适的仪器测量电流强度，只好用一个直接的方法：他让自己触电，以疼痛的程度估计电流的强度（他居然活到了近80岁高龄）。
亨利·卡文迪什非常怕羞，只能勉强同一个人说话——绝不同时和两个人讲话。他在女人面前十分害怕（怕羞或者别的原因），同女佣人只通过字条谈话。如果哪一个女仆在家里碰上他，会被当场解雇。他给自己的屋子单独弄了个入口，这样进出时就不会碰到别人。临终时他坚持自己一个人孤独地死去。
