Definition of a Second
A second is defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium-133 atom. This definition was adopted in 1967 and reflects the precision needed in modern timekeeping.
Understanding Time Units
Time can be broken down into various units, with the second being the base unit. Here are some common conversions:
- 1 second = 1,000 milliseconds
- 1 minute = 60 seconds
- 1 hour = 3,600 seconds
- 1 day = 86,400 seconds
History of Time Measurement
The measurement of time has evolved significantly throughout history. Ancient civilizations developed various methods to track time based on natural phenomena.
Early Methods of Timekeeping
Early societies utilized sundials, water clocks, and candles to measure time. The invention of mechanical clocks in the Middle Ages marked a significant advancement in timekeeping accuracy.
Modern Timekeeping
