从古老的挂钟、座钟到现代戴在手腕上的小巧手表,里边都有一个摆(摆是钟表的心脏)。那么摆是怎么发明的呢?据说,早在1583年,意大利人伽利略在比萨大学读医学,当时他才20岁。一天他到教堂去参加崇教仪式。忽然,一阵风吹来,使得悬挂在天花板上的吊灯来回摆动,发出轻轻响声。伽利略抬头看着,似乎他发现了什么?经过仔细观察,他发现了一个秘密,那摆动的吊灯,晃动一次所用的时间似乎相等。回家以后,这个贫苦的大学生就用最简单的材料做了一个机械摆,利用沙漏计时深入研究摆的运
From ancient wall clocks and clocks to modern wristwatches, there is a pendulum (the pendulum is the heart of the watch). How did the pendulum invent it? It was said that as early as 1583, Italian Galileo was studying medicine at Pisa University when he was only 20 years old. One day he went to church to attend an cult. Suddenly, a gust of wind blew the chandelier suspended from the ceiling and swayed back and forth to make a gentle noise. Galileo looked up, as if he had discovered something. After careful observation, he discovered a secret that the swinging chandeliers seemed to be equal in time to shake. After returning home, the poor college student used a simple material to make a mechanical pendulum, using the hourglass timing to delve into the transport
