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 (Julian)
A year (Julian) is the period of time approximately 365.25 days, based on the Julian calendar, used to measure the length of a complete cycle of seasons and calendar years.
History/Origin
The Julian year was introduced by Julius Caesar in 45 BC as part of the Julian calendar reform, replacing the Roman calendar. It standardized the year length to 365 days with a leap year every four years to account for the extra quarter day.
Current Use
The Julian year is primarily used in astronomical calculations and historical contexts. It is also the basis for the Julian date system used in astronomy and other sciences to record continuous days.
