Who invented time? Who invented time

Time is self-invented!

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 hit the clock, and the structure is very similar to modern clocks. With an error of only one second per day, the water transport platform is equipped with an escapement that makes a ticking sound while working. <

Su Song: Su Song (December 10, 1020, June 18, 1101), the name Zirong, was originally from Tong'an County, Quanzhou Prefecture, Fujian Province (now Tong'an District, Xiamen City), and later migrated to Danyang, Runzhou. In the middle of the Northern Song Dynasty**, he was an outstanding astronomer, astronomical machine manufacturer, and pharmacist.

Su Song is studious, and he knows everything in the nine streams of scripture and history, the theory of a hundred schools, as well as algorithms, geographies, mountain classics, materia medica, exegesis, and law. His main contribution is to science and technology, especially medicine and astronomy. He led the manufacture of the world's oldest astronomical clock, the "Water Transport Instrument Elephant Tower", which opened the precedent of modern clock escapements.

Known as "one of the greatest naturalists and scientists of ancient and medieval China."

1. Compass:

Inventor: The inventor of the compass is still undecided.

A compass is a simple instrument used to determine directions. Formerly known as Sinan. The main component is a magnetic needle mounted on a shaft that can be rotated freely. The north pole of the magnetic needle points to the north pole of geography, and the direction can be discerned using this performance.

2. Papermaking.

Inventor: The inventor of papermaking is unknown, Cai Lun.

Improvement. Also known as Cai Hou paper) Cai Lun improved. In the first year of the Eastern Han Dynasty and Emperor Yuanxing (105 AD), Cai Lun made plant fibers suitable for writing on the basis of summarizing the experience of his predecessors in manufacturing silk weaving crystals.

Paper, the improvement of papermaking, made paper a commonly used writing material. It is known as "Caihou paper".

3. Gunpowder. Inventor: Sun Simiao.

Gunpowder was invented by Han Chinese alchemists in the Sui and Tang dynasties, and the study of gunpowder began in ancient Taoism.

Alchemy, the ancients refined the elixir in order to seek immortality, the purpose and motivation of alchemy were advanced, but its experimental methods still had merits, and finally led to the invention of gunpowder.

4. Engraving printing:

Inventor: Northern Song Dynasty.

It is reported that Bi Sheng invented the clay movable type printing technique during the Northern Song Dynasty.

It is considered to be the world's first movable type printing technology. Engraving printing is known as a "living fossil" in the history of printing, and Yangzhou is Chinese engraving printing.

It is one of the birthplaces of China, and it is the only city in China that preserves a full set of ancient engraving and printing techniques, and the state attaches great importance to intangible cultural heritage.

The compass was invented during the Warring States period. Gunpowder was invented during the Sui and Tang dynasties. Papermaking was invented in the Eastern Han Dynasty.

Block printing was invented in the Tang Dynasty. China's four major inventors are: Zhang Heng, Bi Sheng, Cai Lun, and Du Shi.

The inventions of these four people continue to contribute to human society to this day.

Extended information: China's four major inventions were introduced to the West before the emergence of modern European civilization, and had a certain impact on the development of Western science and technology. The adoption of gunpowder and firearms destroyed the ideological yoke of medieval Catholicism in Europe.

The compass reached the hands of European navigators, making it possible for them to discover America and make it possible to sail around the world, laying the foundations for the development of world and workshop crafts for the West.

Joseph Needham's praise and emphasis on these four great inventions made this statement gain great recognition in China and was written into textbooks.

Engels wrote in his 1857 book Artillery: "In China, pyrotechnic powder was made from saltpeter and other ignition agents at a very early stage, and it was used in military affairs and grand ceremonies."

Gunpowder was first recorded in the alchemy books of the late Tang Dynasty in the 9th century AD.

In 904 A.D., Yang Xing's secret army besieged Yuzhang (now Nanchang, Jiangxi), and the general Zheng Fan ordered the department to "start the flying fire, burn the dragon and sand gate, lead the strong men to enter the city first, and scorch the body", which is the earliest use of gunpowder in military records, and the earliest gunpowder ** appeared in the Dunhuang murals of the Five Dynasties.

The murals of Dunhuang (then part of the Guiyi Army) during the Five Dynasties of the 10th century are the earliest known depictions of muskets and grenades. The world's earliest metal firecracker was unearthed in Heilongjiang, China, made in 1288, and is now in the Heilongjiang Provincial Museum.

Among the ancient timekeeping tools, the first to be produced was the watch. For a long time, people discovered that the shadow of the sun shining on trees would change, so people invented the obeki, which was to stand a straight pole on the ground and observe the change of its shadow to understand the time. The stone slab on which this pole is placed is Kei, and the pole is called a table.

Evolved from Omote-gyu is the sundial. The meaning of a sundial is the shadow of the sun. Compared with the watch, the sundial is more specific and complete, with specific scale markings.

The sundial is also a timekeeping tool that has been used in China for thousands of years. However, sundials also have disadvantages, according to the sun to observe and confirm the time, then when the rainy day, the sun is obscured by clouds and rain, the use of sundial timing is not very convenient.

So the sundial is based on the sun, and when the sun sets and the moon rises at night, how to keep the time? Therefore, people borrowed the principle of sundials and thought about whether they could use the changes of the moon at night to keep time, and moondials were born. However, compared to sundials, the disadvantages of moondials are more obvious.

Moondials can only correctly display the time when the moon is full and the moonlight is abundant, and other times there will be large errors, so more rigorous moondials are usually accompanied by an error note to guide people to correctly confirm the time.

In order to be able to keep the time correctly at any time, the ancients invented the missing engraving. The leakage is timed according to the principle of water equalization dripping. The leakage refers to the water dripping, and the engraving is the arrow engraved with a ruler.

Also according to the principle of water, Zhang Heng of the Eastern Han Dynasty invented the water transport armillary sphere, and the subsequent dynasties have improved on this basis and constantly improved the timing device.

In principle, the time is set at 12 o'clock at the time of the highest sun in the local area.

The current time setting is to divide the region into various time zones, define the time zone, use the time measured by the Greenwich Observatory as the standard time, and so on, and so on, to obtain the standard time that is currently in use.

It's a long story! In fact, the first person to invent the clock was not the first to "know" the time!
