我们所有人都有时间意识。我们用闹钟、布谷鸟钟、手表、落地式大摆钟包围自己,盯着它们看,以确保我们遵守时间表。但是你有没有花一点时间思考过,为什么钟面上的指针会这样移动呢?为什么时针和分针从左向右(以现在称为“顺时针方向”的方式)移动,而不是向相反的方向呢?不,这不是发明者的心血来潮。事实上,对此有科学的解释。
All of us are time conscious.We surround ourselves with alarm clocks,cuckoo clocks,wristwatches,grandfatherclocks and peerat them to make sure we are sticking to our schedule.But have you ever taken a moment to wonder why the needles on the face of a clock move the way they do?Why do the hour and minute needles move from left to right(in what is now called the“clockwise direction”)and not vice versa?No,it is not the whim of the inventor.Actually there is a scientific explanation for this.
