History

Today we take understanding the time and the day of the 12 months for granted but for our ancestors, it was much more difficult. Until mechanical clocks had been invented in the 13th century there have been various ways of telling the time. The earliest technique of telling the time of day used to be the sundial. It is no longer acknowledged when the sundial was once invented but they were truly used in Ancient Egypt and Ancient Iraq.

Other historical civilizations such as the Greeks and the Romans also used sundials. Over time sundials steadily grew to become more correct and they remained a common way of telling the time until the early nineteenth century. About 1400 BC the Egyptians invented the water clock. It consisted of two containers of water, one of which used to be greater than the other. Water flowed alongside a tube from the greater container to the decrease at a consistent rate.

Rings have been marked on the internal of the lower container and when the water stage reached one it meant every other hour had passed. The Saxons used a candle clock. A candle used to be divided into segments and it took an hour for each segment to burn. The mechanical clock was once invented in the middle Ages. Who made the first one and when is not recognized but it was once around the cease of the 13th century? In 1309 a clock is recorded in a church in Italy. The oldest working clock in the world is in Salisbury Cathedral. It dates from 1386 and it has no dial.

Instead, it chimes the hours. (Our word clock comes from the Latin word for bell ‘clocca’). Early clocks were usually in church buildings and they had been very heavy because they were worked by means of weights. However, about 1450 the coiled spring was once invented and it made feasible transportable clocks. The first watches have been made in 1510. In the 16th century, some rich human beings had clocks in their residences but they were very expensive. Early clocks were no longer very accurate but in 1657 Christiaan Huygens introduced the pendulum.

Clocks grew to become far more accurate even though they had been nonetheless set using sundials. In the late seventeenth clocks with lengthy cases had been made. In 1876 a man named Henry Clay Work wrote a piece of music known as My Grandfathers Clock and in the early 20th century they became known as Grandfather clocks. Meanwhile, the cuckoo clock had been invented c. 1775. The stopwatch was invented in 1776 and the electric clock was invented in 1840. The quartz crystal clock was invented in 1929 and the atomic clock was invented in 1955.

In Britain, each town had its personal time and it was now not standardized until the 1840s with the coming of the railways. International time zones together with Greenwich Meantime have been formed in 1884. Watches have been very bulky until c.1675 when the spiral hairspring was invented and current pocket watches evolved. The electric watch was first introduced in 1957 and the quartz crystal watch was introduced in 1967.

However, sundials were used long after clocks had been invented. In the Middle Ages and the 16th century, many people carried pocket sundials. Several pocket sundials have been discovered on the Mary Rose, which sank in 1545.

Description

A clock is a tool used to evaluate, maintain and specify the time. One of the oldest human inventions, the clock resembles the need to measure time intervals shorter than the natural units: day, the lunar month, and year. Over the millennia, devices working on several physical procedures were used.
