世界上第一只摆钟是根据什么原理制成的,请问世界上第一只摆钟是谁制造的?
据绿润百科网站「無畏的掙紮δ」消息,近日,世界上第一只摆钟是根据什么原理制成的,请问世界上第一只摆钟是谁制造的?引发热议,世界上第一只摆钟是谁制造的同样引起许多争议,对此众网友各抒己见。但到底是怎么回事呢?绿润百科为您解答。
世界上第一只摆钟是根据摆的等时性原理制成的。意大利科学家伽利略最早发现摆的等时性原理。某摆球来回摆动60次所用的时间为2分钟,则该摆球来回摆动一次的时间为2秒。1656年,惠更斯利用钟这一原理制成了世界第一座摆钟。
摆钟的发展历程:
此后利用振动原理计时,使时间的计量发生了突破性变化,大致经历了机械摆钟、石英钟、原子钟三个历程。老式的挂钟靠摆轮和游丝电;子表是利用电磁振动的等时性来计时的。石英钟是利用石英晶体振动的等时性来计时的。世界上第一架原子钟是1949年美国国家标准局制作的。由于原子钟振动频率特别稳定,因此原子钟十分准确,30万年也相差不到一秒。
答:克里斯蒂安.惠更斯。摆钟的发明人是克里斯蒂安.惠更斯,在1657年,荷兰物理学家和天文学家克里斯蒂安.惠更斯利用摆的等时性原理发明了摆钟。但是根据的原理是伽利略发现的。意大利物理学家和天文学家伽利略发现了摆的等时性。克里斯蒂安.惠更斯利用伽利略的发现发明了摆钟。
【英文介绍/For English】:
The worlds first pendulum clock was made according to the isochronism principle of the pendulum. The Italian scientist Galileo Galilei was the first to discover the isochronism principle of the pendulum. The time for a pendulum to swing back and forth 60 times is 2 minutes, then the time for the pendulum to swing back and forth once is 2 seconds. In 1656, Huygens made the worlds first pendulum clock using the principle of clocks.
The history of the pendulum clock:
Since then, the use of vibration principle to time time has made a breakthrough change in the measurement of time, which has roughly gone through three processes: mechanical pendulum clock, quartz clock, and atomic clock. Old-fashioned wall clocks rely on balance and hairspring electricity; sub-watches use the isochronism of electromagnetic vibrations to keep time. Quartz clocks use the isochronism of quartz crystal vibrations to keep time. The worlds first atomic clock was built in 1949 by the National Bureau of Standards. Because the vibration frequency of atomic clocks is very stable, atomic clocks are very accurate, and the difference is less than one second in 300,000 years.
