The quartz alarm clock can also be called a “crystal vibration electronic watch” because it uses the “vibration phenomenon” of the crystal wafer. When the crystal receives the external force voltage, it will have the property of deformation and expansion. On the contrary, if the crystal is compressed, it will generate electricity at both ends…
In 1088, the Song Dynasty scientists Su Shi and Han Gonglian and others made the water transport instrument platform, which is a device that combines funeral, scorpion and mechanical timers. It uses hydraulic power as the power source and has a scientific escapement. It is about 12 meters high and seven meters square. It is…
Before 1300 AD, humans mainly used astronomical phenomena and continuous movement of flowing materials to time. For example, the sundial is the azimuth timing of the sunshade; the leaking pot and the hourglass are flow meters that utilize water flow and sand flow. In the Eastern Han Dynasty, Zhang Heng made a leaking water switch…
