What is a second?

 

Second is a very shot period of time. We can't remember all seconds. But some critical seconds are important and easy to remember. It depends on life. So the second (s or sec) is a measurement unit of time, which represents the Standard International (SI) system.  One second can be described as an elapse of 9,192,631,770 radiation cycles, produced by the some transition between two levels of the cesium 133 atom. Seconds can be measured by mechanical clocks, also electronic devices. The earliest clocks to display seconds appeared during the last half of the 16th century. I doubt, because people measured seconds in ancient Greece, and they had some mechanical devices similar to clocks. The unit was defined originally as a fraction 1/86 400 of the mean solar day.:

60s = 1 minute,

60 * 60s = 1 hour,

24 * 60 * 60s = 1 day.

 

There are many descriptions of second ... Period is so short to remember, but descriptions are bunches. Engineers and scientists try to make new concepts of second every day. But what is it really? What is second for that unknown man in the street, when waiting bus? What is the second, when loved person dies? What is second in car accident?

 

It is everything. It is the life.
