World history is divided before and after James Watts.

 Before and after his invention of the "steam engine"... ...Puhehehe... ...the invention of the steam engine by James Watt of England in 1785. This is the core of the industrial revolution, not natural power or manpower, but the beginning of fossil raw material power. Is it too much of a lie to say that everything in modern times has begun... ...and In the 19th century, a country with a lot of coal was the first. The era of steel and coal began in 1806 when Fulton, the United States, built a steamboat (wooden), Stevenson, the United Kingdom, built a train in 1830, and Britain built the Great Britain, the first steel steamer, in 1842. In 1876, Edison in the United States powered electricity with the invention of a "generator," and around the same time, a gasoline engine was invented by Germany in 1896. Thanks to this, with the opening of the 20th century, coal => oil. Britain and the U.S. quickly secured. Germany and Japan lost. After World War II, nuclear power. Uranium emerged as new fossil fuel. Thanks to most of our electricity production... ...when war breaks out, we're a hell of radiation. A few days ago, we fought in South Chungcheong Province or South Jeolla Province over a nuclear dump... ...cheap and clean, but once it happened, a huge accident. The Soviet Union's Chernobyl nuclear plant accident in the 1980s was a nightmare. At that time, even near nuclear power plants in Korea, people teased me about whether people with bad brains lived near nuclear power plants. The airplane was also a steam engine when the Chowlight brothers invented it In 1939, Nazi Germany's Mesashmit jet engine and submarine aircraft carriers were replaced by nuclear propulsion after World War II. (Victory countries only.) Steam engines disappeared in the 20th century, but even trains were not found after World War II. Replace with a diesel engine. The invention changed everything... ...or it was the beginning of the modern era... ...but it was not an exaggeration to say that Japan had recently made a new one for pleasure. It's a little over the top, but the short clip is a Japanese animation called "Steam Boy. Miyoung's conspiracy over the super steam engine Steamball... against the backdrop of the 1866 London World Exposition. Japanese people are good at making a cartoon. Although the characters are all American and British. James Watt's majesty ====================================================================== James Watt 1736 January 19 Greenock, Renfrewshire, Scotland, August 25, 1819, Heathfield Hall near Birmingham, Warwick. a Scottish machine maker and inventor Watt, an oil painting by H. Howard, whose steam engine contributed substantially to the Industrial Revolution, and he was elected a member of the Royal Society in 1785. His father, an accountant and junior judge at Greenock for education and training, was successfully running shipbuilding and construction projects. Watt, a boy with a delicate personality, was educated by his mother at home for some time, and later learned Latin, Greek, and mathematics at Grammar School. An important source of his education was his father's workshop, where he equipped his tools, workstations, and forging, built models such as cranes and barrel organs, and gradually became familiar with ships. At the age of 17, he decided to become a math tool maker, and first went to Glasgow, where one of his maternal relatives was teaching at the university, and in 1755, he went to London to meet a teacher who would teach him. Although his health deteriorated within a year, he acquired the job well as as as an excellent craftsman. Returning to Glasgow, he opened a store at the university in 1757 and made mathematical tools such as quadrants, compasses, and scales. He met many scientists and became friends with Joseph Black, who developed the concept of latent heat (the heat needed to change the state of substances such as solids and liquids). She married her cousin M. Miller in 1764, but nine years later she died with six children. The Watt engine was shocked by the waste of steam in 1764 while repairing a model of the New Common steam engine. After grappling with the problem of improving it, he accidentally found the answer, his first and greatest invention, the "separator." He knew that the loss of latent heat was the biggest disadvantage of the New Common engine, so it was connected to the cylinder, but condensation had to be made in a separate chamber. Then he met J. Robert, founder of the Caron plant, who authorized him to produce the institution. After becoming a partner with him in 1768, he created a small testing agency with Joseph Black's loan, and the following year obtained a patent known for the New Development Act, which reduces steam and fuel consumption in a thermal engine. In the meantime, Watt became a surveyor in 1766, and for the next eight years he continued to work on the path of a canal built in Scotland, which prevented him from advancing the steam engine. After Robert went bankrupt in 1772, M. Bolton, a manufacturer of the Soho plant in Birmingham, patented Watt. Tired of surveying and Scotland, Watt moved to Birmingham in 1774. After his patent rights were extended by Congress, in 1775 he began a partnership with Bolton that lasted for the next 25 years, and Bolton's financial support allowed the agency to make rapid progress. In 1776, the two institutions were the pumping station of the Staffordshire coal mine and the famous steelmaker J. It was installed in Wilkinson's Row for blast. That year, Watt remarried his second wife, A. McGregor, and had two more children. After that, he spent five years in Cornwall until 1781, installing and supervising a number of pump engines in copper and tin mines, where managers wanted to reduce fuel costs. As a non-businessman, he had to endure intense negotiations to get a decent fee for the new agency. In 1780, he was financially safe, but Bolton had problems with capital accumulation. Bolton, who predicted a new market for corn, malt and cotton plants the following year, encouraged Watt to devise a rotating motion of a steam engine that would replace the existing reciprocating motion. This problem was solved in 1781 by devising a so-called planetary gear device in which the axis rotates twice for each cycle of the engine. In 1782, at the height of his invention, he was patented as a double-acting organ in which pistons were simultaneously pushed and pulled. The agency needed a new way to connect the moving beam and the piston securely. He solved this problem in 1784 with the invention of a horizontal motion device (a device that combines a rod that guides the piston rod to vertical motion), which he described as "the most genius and simple piece of device I have ever invented". Four years later, following Bolton's proposal, he completed the actual watt engine with the use of a centrifuge that automatically controls the speed of the engine and a pressure gauge invented in 1790. The demand for late wattage institutions rapidly appeared in paper mills, mills, cotton mills, steel mills, distilleries, canals, and water supplies. He became rich for 11 years until 1790, receiving 76,000 pounds in patent fees, but the steam engine did not capture all of his attention. He was a member of the Luner Society in Birmingham, a group of writers and scientists hoping for the advancement of science and art. He tested the strength of materials, and his proceedings were frequently involved in patent protection. In 1785, he was elected a Fellow of the Royal Society of London with Bolton. From this point on, Watt began to take time off by buying land in Doldaulod, Radnorshire, and gradually retired from business in 1795. In 1800, he established a new Wat & Bolton Company in 1794 as his retirement approached, as well as the expiration of the patent and partnership, which built a Soho foundry to make the steam engine more complete. At this time, James, the Watt deficit, caused problems. James, a young sympathizer of the French Revolution, was criticized by Congress for releasing a letter from the Constitutional Council of Manchester to the Constitutional Council of Paris. Two years later, he returned home from political charges and took over the management of the new company with Bolton's son, Matthew. Watt's long retirement was depressed by the death of his son, Gregory, and many close friends. Nevertheless, when the Treaty of Amiens was signed in 1802, he traveled with his wife to Scotland, France, and Germany, where he continued his research in the attic of his home, where he made sculptural machines to recreate the busts of his friends. He also served as an advisor to the Grasgowater Company. His work was widely recognized during his lifetime, becoming a Ph.D. in law from the University of Glasgow in 1806 and a foreign associate of the French Academy of Sciences in 1814, and a quasi-Boner was awarded, but he refused.
