Hour (Sidereal)
An hour (sidereal) is a unit of time based on the Earth's rotation relative to distant stars, equal to approximately 3,894 seconds, used primarily in astronomy.
History/Origin
The sidereal hour originated from the ancient division of the day based on Earth's rotation relative to the stars, differing from the solar hour by about 4 minutes, and has been used historically in astronomy for precise timekeeping.
Current Use
Sidereal hours are mainly used in astronomy and astrophysics to measure celestial events and the Earth's rotation relative to distant celestial objects, rather than in everyday timekeeping.
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.
