In 1837, Cook and Wheatstone designed and manufactured the first cable telegraph in England, and continued to improve it, and the speed of transmission continued to increase. This telegraph soon found an application in railway communications. Their telegraph system was characterized by messages pointing directly at the letters.
At the same time, the American Morse was also fascinated by the telegraph. He was a painter who, with his rich imagination and indomitable fighting spirit, achieved what many people dreamed of. When he was 4l years old, he returned to the United States from studying painting in France and was introduced to the magical world of electromagnetism by the doctor Jackson.
On board, Jackson showed him"Electromagnets", as soon as the electric energy is turned on, the iron device will fall off as soon as the electric iron is broken. Also said"No matter how long the wire is, the current can pass through at great speed"。This gadget made Morse reverie:
Since electric current can be passed through a wire instantaneously, can it be used to transmit information? To do this, he wrote in his picture book"Telegram"Determined to complete the invention of using electricity to transmit information.

Although the development of the telegraph began as early as the beginning of the 19th century, the invention of the practical electromagnetic telegraph was mainly attributed to the British scientists Cook and Wheatstone and the American scientist Morse. In 1836, Cook made an electromagnetic telegraph and applied for the first telegraph patent the following year. Wheatstone was Cook's collaborator.
Morse was originally a first-class painter in the United States, out of interest, he developed a prototype of the electromagnetic telegraph in 1835, and later invented the "Morse code" composed of dots and strokes in 1838 according to the two signals of electric current, electric spark and no electric spark when it is broken.
Scientific American magazine reported in July 1858:It is well known that the British have always claimed that the magnetic telegraph was invented by their compatriot, Professor Wheatstone.
On the other side of the Atlantic, the establishment of the telegraph company has caused more Europeans to start discussing who is the real inventor of the telegraph. According to the Moniteur of Paris, France, Morse was not the creator of the telegraph principle, but he was the first to put it into practice.

At the beginning of the 19th century, the lack of fast communication tools made it extremely difficult to transmit important information, and at the same time restricted the development of technology and society. Thus, in this context, the advent of the telegraph provided a new possibility for solving the problem of information exchange. The first viable telegraph was invented in 1816 by the Englishman Francis Ronald, but it was actually the Americans Samuel F. B. Morse and Alfred V. Mormans who collaborated to invent the first reliable telegraph system.
The advent of the telegraph profoundly changed people's lives, making people's dream of long-distance communication realize overnight. It only took a few seconds or minutes for a message to reach its destination over long distances, which was a remarkable technical achievement at the time. At the same time, the emergence of the telegraph also accelerated the cultural exchanges of countries around the world and promoted the development of human civilization.
At the beginning of the 20th century, with the development of ** technology, the telegraph was gradually eliminated, but it created a precedent for long-distance communication and paved the way for later communication technology. Looking back on this period of history, we can see that the continuous scientific and technological progress and reform of the wheel collapse and lead and tung trap are the guarantee for mankind to move forward.

The inventor of the telegraph was Samuel Morse. Morse's original profession was not a scientist, but a painter, and the reason why he came up with the idea of inventing the telegraph was because Dr. Jerson told Morse that no matter how long the wire, the current can pass quickly, which made Morse interested in the electric current, and since then he has embarked on the road of inventing the telegraph.
Features of Morse Telegram:This earliest telegraph machine because it completely depends on human operation, its notification rate is very low, even the most skilled telegrapher, can only send and receive about 20 groups of words per minute, but Morse artificial telegraph equipment is simple, Weiqing Zhi fiber repair is convenient, stable working performance, because of the fierce land has been used to this day, especially in the field exploration or field warfare, to a large extent rely on it for communication contact.
Morse Express includes equipment such as keyboard drills, automatic transmitters and corrugated receivers, most of which are driven by small electric motors. When using, the sender's operator first uses a keyboard drilling machine to chisel out the Morse symbol hole in the chiseled paper, and then sends the chiseled paper to the automatic transmitter to send the report, and the receiver uses the corrugated receiver to receive the report.

The telegraph originated in the United States.
Although the development of the telegraph began as early as the beginning of the 19th century, the invention of the practical electromagnetic telegraph was mainly attributed to the British scientists John Cook and Wheatstone and the American scientist Morse. In 1836, John Cook made an electromagnetic telegraph and applied for the first telegraph patent the following year. Wheatstone was a collaborator of John Cook.
Morse was originally a first-class painter in the United States, out of interest, he developed a prototype of the electromagnetic telegraph in 1835, and later invented the "Morse code" composed of dots and strokes in 1838 according to the two signals of electric current, electric spark and no electric spark when it is broken.
The telegraph was one of the first means of telecommunication to transmit information, reliable and instantaneous, and it was developed in the United Kingdom and the United States in the thirties of the 19th century. Telegraph messages are sent out as electrical signals over a dedicated switching line, which is coded instead of words and numbers, usually using Morse codes. Now, with the popularization of **, fax, etc., the telegraph has been rarely used.

Year 1684.
British physicist Robert. Hooker invents the return light signal. At the Royal Society, he for the first time vividly outlined the details of a communication system. However, this communication system has not been successfully tried.
Year 1745.
Bishop Kleist of Pomerania invents the capacitor.
Year 1747.
In the UK, cheap. Sir Walsh discovered that it was possible to propagate an electric current on a metal conductor.
Year 1753.
On 17 February, Edinburgh's Scotsman magazine received a letter signed by a man. The letter suggested that a set of 26 metal wires should be run parallel to each other, horizontally from one place to another. The metal wire is attached to an electrostatic motor at one end and a ball at the far end, representing an English letter.
Underneath the ball hangs a piece of paper with the letter written on it. When the report is sent, the current is turned on, and the other party's ball sucks up the paper. This was the earliest idea of using electricity for communication.
Year 1793.
The French brothers Chappé erected a 230-kilometre-long relay carriage line between Paris and Lille. It is said that one of the two brothers was the first to use the word "telegram". Resources.
Korean kimchi originated from Dawan Town, Jiangbei County, Chongqing City (now Yubei District, Chongqing City), and the Tang Dynasty general Xue Rengui was sent to Goryeo (now South Korea) and settled in Goryeo (now South Korea). Many of his entourage are from Jiangbei County, Chongqing City, and they can make kimchi from their hometown, and from this time on, Chongqing kimchi entered South Korea, and several wars in South Korea allowed this dish to enter Korean civilian families. Historically, Korea has been an agricultural country, and rice has been a staple food since ancient times. >>>More

Mountain bikes are bicycles designed for off-road (hills, trails, wilderness, gravel trails, etc.) and were born in San Francisco on the West Coast of the United States in 1977. At that time, a group of young people who were keen to ride beach bikes to have fun on the hillside had a whim: "It would be very fun to be able to ride a bicycle down the mountain." >>>More
