Who invented the clock? Who invented the clock?

In 1350, Dandi of Italy made the first mechanical time-beating tower clock with a simple structure, with a daily difference of 15 30 minutes, and the indicating mechanism was only the hour hand; 1500 In 1510, Henleith of Germany was the first to replace the heavy hammer with a steel mainspring and created a small mechanical clock with a corona-wheel escapement; Around 1582, Galileo Galilei of Italy invented the gravitational pendulum; In 1657, Huygens of the Netherlands introduced gravity pendulum into mechanical clocks and created pendulum clocks. In 1660, Hooke of England invented the hairspring and replaced the corona-wheel escapement with a retracting escapement; In 1673, Huygens applied a governor composed of balance springs to portable clocks; In 1675, Clement of England made the simplest anchor escapement with a fork tile mechanism, which has been used in simple pendulum wall clocks. In 1695, Tom Ping of England invented the I-wheel escapement; In 1715, Graham of England invented the stationary escapement, which made up for the shortcomings of the retracting escapement and laid the foundation for the development of precision mechanical clocks; In 1765, March of England invented the free-anchor escapement, the predecessor of the modern fork-and-tile escapement; 1728 In 1759, Harrison of England manufactured a high-precision standard marine clock; 1775 In 1780, Arnold of England created an escapement for precision watches.

In the 18th and 19th centuries, the watchmaking industry gradually industrialized and reached a fairly high level. In the 20th century, with the rapid development of the electronics industry, battery-driven clocks, alternating current clocks, electromechanical watches, pointer quartz electronic clocks, and digital quartz electronic clocks have come out one after another.

Mechanical clocks were invented in the 13th century. It was designed to control the gravity of the drop weight, and in the 15th century it was designed to control the return of the spring. In Europe, the earliest record of a mechanical chronograph was found in the sketchbook of the French architect de Onnecort (c. 1250 – c. 1300).

Most of what he painted was seen during his travels, so it is likely that this machine was not invented by himself. Although he did not explain, there is such a note under the sketch: "If you make an angel pointer pointing to the sun".

This suggests that there is a good chance that the hand is rotating once every 24 hours. If you want the clock to strike the time, you have to design a set of striking gear trains, usually driven by a separate hammer or mainspring, that release energy between the movements of the needle train when it turns. The time of the invention of the clock striking gear train is uncertain.

The oldest surviving clock capable of striking the time in Salisbury Church was made in 1386.

The first clocks appeared in the Northern Song Dynasty and were invented by Su Song.

In 1092, Su Song, the prime minister of the Northern Song Dynasty, presided over the construction of a water transport instrument elephant platform, which can tell the time and strike the clock, and the structure is very similar to modern clocks.

What's even more incredible is that the water transport instrument has an error of only 1 second per day, and it is also equipped with an escapement that can make a "tick, tick" sound when working.

The principle of clocks. Clocks have a wide range of applications and many varieties, which can be classified according to the principle of vibration, structure and use characteristics. According to the principle of vibration, it can be divided into clocks and watches that use mechanical vibration with lower frequency, such as pendulum clocks, balance clocks, etc.; Clocks that use high frequency electromagnetic oscillations and quartz oscillations, such as synchronous electric clocks, quartz clocks, etc.

According to the structural characteristics, it can be divided into mechanical watches, such as mechanical alarm clocks, automatic, calendars, double calendars, springs and other mechanical watches; Electromechanical, such as electric pendulum clocks, electric balance wheel clocks, etc.; Electronic, such as balance wheel electronic clocks, tuning fork electronic clocks, analog and digital display quartz electronic clocks, etc.

In 1092, the Northern Song Dynasty Qin Xingshu Lord Chi built a water swimsuit, like lifting this skill to make stones to fight the end is enough and modern clocks are very zombie.

The clock was invented by Libby, and primitive man judged time by the source and return of the color of the sky and the luminosity of the sun. The ancient Egyptians discovered that the length of shadows changes with time, invented the sundial to keep time in the morning, and discovered that the time required for the flow of water to flow was fixed, so they invented the water clock. The ancient Chinese also had a tool to keep time with water - copper kettle dripping, and they would also use incense to keep time.

Put the incense horizontally, and put a rope with steel balls on it, which has the function of telling the time. In 1283, the first mechanical clock in England was found to be driven by weights. In the 13th century, monks in northern Italy began to build bell towers, or bell towers, to remind people of the time to pray.

In the mid-16th century, hail feasts in Germany began to have a table clock. The clocks had only one needle, and the face was divided into four parts, allowing the time to be accurate to the nearest 15 minutes. In 1657, Huygens discovered that the frequency of the pendulum could calculate time, and created a pendulum clock for the first auspicious.

In 1670, the Englishman William Clement invented the anchor escapement. In 1797, the American Eli Terry obtained a patent for a clock. He is regarded as the progenitor of the American watch industry.

Legend has it that the world's brightest person who first invented a mechanical clock was Guo Shoujing of the Yuan Dynasty of China. In 1267, Guo Shoujing made a mechanical clock for special timing in the Daming Palace, which can "ring the bell at one quarter, drum at one quarter, cymbals at the beginning, and four coins". In addition, as early as 1090, Su Song, the prime minister of the Northern Song Dynasty, created and invented the world's first mechanical timer equipped with a control mechanism, called "digging stool water transport instrument image platform", but there is a large difference with the clock of later generations.

The first time in the world to use a "pendulum" to control a clock was the Dutch scientist Huygens. In 1656, Huygens built the first mechanical pendulum clock. During World War I, a soldier fastened his watch to his wrist for convenience.

Inspired by this, a Swiss mechanic began to make a smaller watch with pinholes on both sides of the watch to hold leather or metal straps to attach the watch to the wrist.

The first person in the world to invent a mechanical clock was Zhang Heng of the Eastern Han Dynasty.

In 1656, Huygens built the first mechanical pendulum clock.

In 1582, the Italian scientist Galileo Galilei proposed the law of the oscillation of a single pendulum.

In 1657, the Dutch scientist Huygens used the principle of a single pendulum to make the first pendulum clock. From then on, time was measured more accurately, and the units of timekeeping began to be calculated in hours, minutes, and seconds.

To be precise, the clock was invented by Huygens.

Christian Huygens is a Dutch physicist, astronomer and mathematician. He is an important pioneer of physics between Galileo and Newton, one of the most famous physicists in history, he has made outstanding contributions to the development of mechanics and the study of optics, and has also made outstanding achievements in mathematics and astronomy, and is an important pioneer of modern natural science. He established the law of centripetal force, proposed the principle of conservation of momentum, and improved the timer.

1. Clocks and watches were invented by the Chinese during the Northern Song Dynasty more than 900 years ago.

2. Clocks and watches are the collective name of clocks and watches, clocks and watches are precision instruments that measure and indicate time, clocks and watches are usually distinguished by the size of the internal machine, and the watch is one of the smallest, strongest and most sophisticated machinery invented by human beings.

3. There are two types of prime mover closing force in modern clocks: mechanical force and electric power. A mechanical clock is a kind of timer that uses the release energy of a hammer or spring as the power to push the gear of a car key series to run, and indicates the time and measures the time with the pointer; An electronic clock is a timer powered by electricity, with liquid crystal display digital and quartz hands.

Zhang Heng。Before 1300 AD, humans mainly used astronomical phenomena and the continuous movement of moving matter to keep time. For example, a sundial uses the azimuth of the sun's shadow to keep time; The leaky pot and hourglass are used to measure the flow of water and sand.

Zhang Heng of the Eastern Han Dynasty made a leaky armillary sphere, and used a gear system to connect the armillary image with the timing leaky pot, and the leaky pot dripped water to promote the armillary image to rotate evenly, and the day just turned around for a week, which was the earliest mechanical clock to appear.

A mechanical clock is a timer that uses the released energy of a hammer or spring as the power to drive a series of gears, adjusts the speed of the wheel train with the help of an escapement governor, and indicates the time and measures the time with a hand.

Clocks and watches have always been one of the favorite commodities of Chinese people:

Since the founding of the People's Republic of China, the state has invested a lot of money in the development of the watch industry, so that the industry has developed rapidly, and since then, China's reform and opening up and the development of economic globalization have brought prosperity to China's watch industry. After decades of development, China's watch industry has experienced the development process of incoming assembly, appearance parts manufacturing, product development and brand creation, and has now formed a complete watch manufacturing industry, except for high-end movements, all spare parts can be processed and produced.

Who invented clocks? Let me take you to know about the jujube!

Who invented the clock

The first clocks appeared in the Northern Song Dynasty and were invented by Su Song. In 1092, Su Song, the prime minister of the Song Dynasty, presided over the construction of a water transport instrument elephant platform, which can tell the time and hit the clock, and the structure is very similar to the modern clock. What's even more incredible is that the water transport instrument elephant table has an error of only 1 second per day, and it is also equipped with an escapement that can make a "world tick, tick" sound when working.

The history of the development of clocks and watches

1. From 140 to 100 B.C., the ancient Greeks made the timer for the Olympic Games with a system of 30 to 70 gears.

2. In the Eastern Han Dynasty in 78 A.D. 139 years, Zhang Heng made a leaky armillary sphere, and used a gear system to connect the muddy image with the timing leaky pot, and the leaky pot dripped water to push the muddy elephant to rotate evenly, and the day just turned around a week, which was the earliest mechanical clock.

In Italy, Dandi built the first mechanical dome clock with a simple structure, with a daily difference of 15 and 30 minutes, and the indicator mechanism had only the hour hand.

In 1510, Henleith of Germany was the first to replace the hammer with a steel mainspring and created a small mechanical clock with a corona-wheel escapement.

Around the same time, Galileo Galilei of Italy invented the gravity pendulum.

Huygens of the Netherlands introduced gravity pendulum into mechanical clocks and created the pendulum clock.

Hooke in England invented the hairspring and replaced the corona-wheel escapement with a retracting escapement.

In the same year, Huygens applied a governor consisting of a balance spring to a portable clock.

In England, Clement made the simplest anchor escapement from a fork tile mechanism, which has been used in simple pendulum wall clocks.
