What is a Shake and a Day?
A Shake is an informal unit of time equal to 10 nanoseconds (10 ns), or 10⁻⁸ seconds. It is primarily used in nuclear physics and astrophysics to measure the timing of events in nuclear reactions and related phenomena.
A day is a unit of time typically defined as 24 hours, which is equivalent to 1,440 minutes or 86,400 seconds. It roughly corresponds to one full rotation of the Earth on its axis relative to the Sun (a solar day).
Note: The Shake is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Day belongs to the imperial/US customary system.
History of the Shake and Day
The term "Shake" originated during the Manhattan Project, the World War II effort to develop the first nuclear weapons. Nuclear chain reactions happen extremely quickly, and physicists needed a convenient, short unit of time to discuss the timing of events within these reactions. Ten nanoseconds was chosen as a practical order of magnitude for many processes involved. The name itself is informal, reputedly derived from the expression "two shakes of a lamb's tail," implying a very short duration.
The concept of a day as a fundamental cycle of light and darkness is ancient. The division into 24 hours developed over time, notably influenced by the Egyptians. While the solar day (time between two successive solar noons) varies slightly throughout the year, the standard mean solar day of 86,400 SI seconds is used for civil timekeeping.
Common Uses for shakes and days
Explore the typical applications for both Shake (imperial/US) and Day (imperial/US) to understand their common contexts.
Common Uses for shakes
The Shake is almost exclusively used in specific technical fields:
- Nuclear Physics: Measuring the time intervals between successive neutron generations in a nuclear chain reaction.
- Astrophysics: Discussing timescales relevant to certain high-energy astrophysical events.
- Particle Physics: Occasionally used in experiments involving very short-lived particles or interactions.
- Laser Physics: Sometimes used in contexts involving very short laser pulses.
It is not used for everyday time measurements.
Common Uses for days
- Civil Timekeeping: The primary unit for organizing daily life, calendars, schedules, and dates.
- Astronomy: Used to measure rotational periods of planets and other celestial bodies (though the definition might differ, e.g., sidereal day).
- Duration: Measuring the length of events, projects, trips, or lifespans that span multiple hours.
- Biology: Studying circadian rhythms (biological processes that follow a roughly 24-hour cycle).
- Work & Rest: Structuring periods of work, leisure, and sleep.
Frequently Asked Questions
Questions About Shake (shake)
How long is a Shake in seconds?
One Shake is equal to 10 nanoseconds (10 ns), which is 10⁻⁸ seconds, or 0.00000001 seconds.
Where did the name "Shake" come from?
The name is an informal term coined during the Manhattan Project. It's believed to be a humorous reference to the phrase "in two shakes of a lamb's tail," signifying a very brief period, appropriate for the rapid events in nuclear reactions.
Is the Shake an SI unit?
No, the Shake is not part of the International System of Units (SI). The standard SI unit for time is the second (s). The Shake is a specialized, informal unit used within specific scientific communities for convenience.
About Day (d)
How many hours are in a day?
There are typically 24 hours in a standard civil day.
How many seconds are in a day?
There are 86,400 seconds in a standard 24-hour day (24 hours * 60 minutes/hour * 60 seconds/minute).
Is every day exactly 24 hours long?
The apparent solar day (time from one noon to the next) varies slightly due to the Earth's elliptical orbit and axial tilt. The mean solar day, used for clocks, averages this out to 24 hours. Leap seconds are occasionally added to keep clock time aligned with the Earth's rotation.
What's the difference between a solar day and a sidereal day?
A solar day is based on the Sun's position (approx. 24 hours). A sidereal day is based on the Earth's rotation relative to distant stars (approx. 23 hours, 56 minutes, 4 seconds).
