Shake
A shake is a unit of time equal to 1/60th of a second, used in measuring short durations.
History/Origin
The concept of the shake originated in nuclear physics and military contexts, particularly in the Manhattan Project, where it was used to denote the time it takes for light to travel 1 centimeter, approximately 3.33 nanoseconds. It was adopted as a convenient measure for very brief time intervals.
Current Use
Today, the shake is primarily used in nuclear physics and scientific research to describe extremely short time intervals, especially in nuclear reactions and particle physics. It is rarely used outside specialized scientific contexts.
Year (Leap)
A leap year is a year that has 366 days, including an extra day (February 29) added to keep the calendar year synchronized with the astronomical year.
History/Origin
The concept of adding an extra day to the calendar was introduced by the Julian calendar in 45 BC and refined by the Gregorian calendar in 1582 to correct inaccuracies in the Julian system, establishing the current rules for leap years.
Current Use
Leap years are used in the Gregorian calendar to maintain alignment with Earth's orbit around the Sun, occurring every four years with exceptions for century years not divisible by 400, ensuring calendar accuracy over long periods.
