## What is a second (s or sec)?

A second is a unit of time. The symbol for second is s or sec. There are 3,600 seconds in an hour.

The second has historically been defined as 1/60 of a minute or 1/86,400 of a day. According the to SI definition, the second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the unperturbed ground state of the caesium 133 atom.^{[1]}

The second is the SI base unit for time in the metric system. Seconds can be abbreviated as *sec*; for example, 1 second can be written as 1 sec.

## What is a minute?

The minute is a unit of time usually equal to (the first sexagesimal fraction) of an hour, or 60 seconds. In the UTC time standard, a minute on rare occasions has 61 seconds, a consequence of leap seconds (there is a provision to insert a negative leap second, which would result in a 59-second minute, but this has never happened in more than 40 years under this system). Although not an SI unit, the minute is accepted for use with SI units. The SI symbol for minute or minutes is min (without a dot). The prime symbol is also sometimes used informally to denote minutes of time.

## A Brief History of a Brief Amount of Time

The Persian scholar Al-Biruni first used the term "second" around 1000. He defined it—as well as the day, hour, and minute—as fractions according to the lunar cycle. The first mechanical clocks to mark the second appeared in the 1500s, and in 1644 French mathematician Marin Mersenne used a pendulum to define the second for the first time, leading to the international adoption of grandfather clocks by the end of the 17th century. In the 19th century, scientific institutions worked to define the second in astronomical terms, and in the 1940s an international agreement defined the second as 1⁄86,400 of a mean solar day.

It was in the 1950s, however, that researchers recognized the Earth's rotation is not consistent enough to provide a standard unit of time. Instead, the second was redefined according to the length of a year, and officially became the fraction 1⁄31,556,925.9747 of the year 1900. The definition would not endure.

Around the same time, the first accurate atomic clocks were being developed that used cesium. Finally, here was a natural phenomenon precise and consistent enough to define a second. In 1967, the Thirteenth General Conference of the International Committee for Weights and Measures officially defined the second as "the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom." And that has remained the official definition ever since.

## How did we come to divide the hour into 60 minutes and the minute into 60 seconds?

These smaller divisions of time have been in practical use for only about 400 years, but they were vital to the advent of modern science.

For millennia, ancient civilizations looked to the sky to measure the big units of time. There's the year, which is the time it takes Earth to complete one orbit around the sun; the month, which is approximately how long it takes the moon to orbit our planet; the week, which is approximately the time between the four phases of the moon; and the day, which is the duration of one rotation of the Earth's on its axis.

Dividing the day was not so straightforward, though hours and minutes have their origins in traditions tracing back thousands of years.

Number systems The use of 60 began with the Sumerians who used different number systems. While you and I write numbers using base 10, or “decimal” this civilization used base 12 ("duodecimal") and base 60 ("sexigesimal"). It is not known exactly why they chose these systems, but there are a few theories: Many ancient cultures used the three segments of each finger to count to 12 on one hand, writes Georges Ifrah in his book, “The Universal History of Numbers” (Wiley, 2000; translated by David Bello). It is hypothesized 60 arose from using five fingers of one hand with the twelve segments of the other. Fewer fractions have repeating decimals (1/3 = 0.333…) when written in sexagesimal. This is particularly important because the Sumerians had no notion of repeating-digit fractions. In “An Introduction to the History of Algebra” (American Mathematical Society, 2009), author Jacques Sesiano describes a tablet that reads, “I don’t know the inverse of 7/6.” Twelve was an important number to the Sumerians, and later to the Egyptians. For example, it was the number of lunar cycles in a year and the number of constellations of the Zodiac. Day and night were each divided into 12 periods, and the 24-hour day was born. To find the origin of thetime cutting, and therefore understand why there are 60 seconds in a minute, we must go back to Egyptian and Babylonian antiquity, to about 3,000 BC. Based on the observation of phases of the moon, which last about 29 and a half days, our distant ancestors established the months. Egyptian astronomers have also calculated, by observing the sky, that a year lasts 365 days. Around -2,800, the year is divided into three four-month seasons, and each month consists of three ten-day weeks, which will then be transformed into seven-day weeks, presumably to allow workers to rest more often on the last day of the week, and also for religious reasons. |
