The opening of the first regular air route has greatly expanded the space for human activities.
190 1 year radio, at the beginning of the 20th century, almost no one could imagine that electromagnetic waves could travel any meaningful distance without any metal wires or cables as conductors. So how do radio signals travel along the surface of the earth? Of course, it can shoot straight off the horizon. But Guillermo Marconi believes that radio waves can travel along the surface of the earth if some conditions are provided. 1895, in his birthplace of Italy, he sent out a radio signal, which passed 1? 5 miles; Six years later, that is, 190 1 year 12 February 12 year, Marconi, who was only 27 years old, created a miracle. He tied the radio antenna firmly to a flying kite and sent a Morse code "S". It flew about 2000 miles across the Atlantic. This signal was sent from Huzhen, Polder, Cornwall, England, and reached St. John's in Newfoundland in less than 1 second. Marconi heard three faint ticks. This is the voice of the birth of the communication industry and the first shock wave of the arrival of the electronic age. This era includes radio broadcasting, television and mobile phones-so this is a discovery that will open our imagination.
Radio 190 1 Italian Marconi successfully conducted the first radio communication.
Transistor radio was invented in 1948.
Fax 1902, the fax is sent for the first time, and the fax is used for business from 1926.
1903 stainless steel, before, steel was not only easy to rust, but also easy to be corroded. From 1903 to 19 12, stainless steel became an outstanding industrial metal as soon as it appeared. Nowadays, stainless steel is not only used in industry, but also widely used in medical treatment and human body.
Orville Wright and wilbur wright were able to fly their plane made of wood, wires and cloth for 59 seconds before sunset. However, few newspapers are willing to comment on this matter, because the idea that humans fly into the sky to become contemporary Daedalus and Icarus is considered absurd by most sober people. But once successful, the development of this undertaking is extremely rapid. In fact, it was only after 15 years that various parts of modern aircraft were manufactured, if not all, then at least ideas about them had been born.
Watches are one of the inventions that have been changed many times in human history, and they are very comfortable to wear.
The watch appears in 1904.
Copier 1907, the world's earliest photographic copier appeared in new york, USA.

Plastic did not exist before this century, but has become an indispensable thing in our century.
It started with the manufacturing method of phenolic plastics invented by American L. Baekeland in 1909.
1907 plastics: after learning about the invention of plastics, the happiest thing in the world is the elephant. For hundreds of years, everything from the handle to billiards has been made of ivory. 19 In the 1980s, the supply of ivory gradually decreased and billiards rose, which once triggered a crisis. Phelan and Cowland, the largest billiards producers in the United States, can't wait to offer a gold prize worth $65,438+0,000 pounds-a considerable prize-to recruit any "invention genius" who can provide synthetic products instead of ivory.
Until 1907, the Belgian inventor Leo Baekeland, who had made huge profits by inventing photographic paper for taking fast-moving photos, accidentally invented the compound of phenol and formaldehyde. This innovative pure synthetic plastic-phenolic plastic has the functions of heat protection, electricity protection and corrosion protection. Not only is it good for billiards, but one of the great benefits of plastic is its versatility. Everything from telephones to toilets, ashtrays to airplane parts is made of plastic. By 1968, if young graduates want to find a job in a promising and successful industry, they must listen to one word-plastic.
