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 (Tropical)
A year (tropical) is the period of approximately 365.24 days, representing one cycle of the Earth's seasons based on the vernal equinox.
History/Origin
The tropical year has been used since ancient times to track seasons and calendar systems, with the Gregorian calendar refining the measurement to align with the Earth's orbit around the Sun.
Current Use
The tropical year is used as the basis for the Gregorian calendar, which is the most widely adopted civil calendar worldwide, to organize years and seasons.
