In 1895 Guillermo Marconi built the first radio system with a range of more than 2 km. In 1901 signals were sent to the other side of the Atlantic. On this day in 1901, Italian radio pioneer Guillermo Marconi sent the first long-distance wireless transmission from the Isle of Wight to Britain's western Cornwall region. Despite the fact that Marconi had sent messages over increasingly distant distances during the five years prior to that day, the January 23 broadcast was a milestone in the development of long-distance communications. Not only it was the longest wireless transmission to date (299), but it also demonstrated that radio waves could be transmitted across the horizon, a fact that most scientists of the time insisted was impossible. This radio did not go on the market therefore there is no specific value in history

Plane 1903

The Wright Flyer (often referred to as the Flyer I and occasionally the Kitty Hawk) was the first powered flying machine built by the Wright brothers. The flight is recognized by the Fédération Aéronautique Internationale, the record-keeping and standards-setting body for aeronautics and astronautics, as "the first sustained flight in an aircraft heavier than air."

This was achieved on Kill Devil Hill in Kitty Hawk, North Carolina, on December 17, 1903, when in the first of four flights recorded that day, and with Orville Wright at the controls, the Flyer remained in the air. for 12 seconds, covering a distance of 37 m; on the fourth and final flight, and with Wilbur Wright as pilot, the distance was 260 m, covered in 59 seconds. This plane did not have a market value since it was only used for the Wright brothers, this plane served as models and thus they were creating many more planes.

Televisión B-W 1926

    The idea of transmitting images at a distance arose from the development of the telegraph, and was affirmed with the telephone and the radio. However, only the discovery and use of electromagnetic waves made it possible. It was a television project that could not be developed back then. Thus, it was the Scotsman John Logie Baird who recovered in 1926, specifically on January 26, this system devised years ago and gave rise to the first real televisión experience. in the city of Hastings, England and the first television picture was broadcast by Baird in 1926. The prices were around according to the size that is to say the inches that the television had. Its price in Japan was 175,000 yen. (At the time, the minimum wage for a high school official was 5,400 yen per month.) In February 1953, NHK began its daily television broadcasts for 4 hours a day.

Computer 1938

The Z1 was a mechanical computer designed by Konrad Zuse from 1936 to 1937 and built by him from 1936 to 1938. It was an electrically operated, mechanical, binary calculator with limited programming that read instructions from perforated celluloid film. The Z1 was the first programmable electro-mechanical computer, born in 1938 in Germany. It is true that its repercussion was far from that of the other machines, in fact, it hardly had any use. Even its creator, Konrad Zuse, admitted that this model never quite worked out well. The idea they had about a computer was born because the elaboration of the mathematical tables was a tedious process and prone to errors. Originally valued at $ 159,000 at the time, the UNIVAC increased its price to $ 1,250. 000 and $ 1,500.000.

Video Camera 1956

John Baird, a Scottish engineer, was one of the pioneers in capturing moving images for television production. ... The video camera as we know it today is capable of recording images and sound. The first demonstration of this ability took place on April 14, 1956.

It cost almost € 50,000 and had little commercial success among consumers, due to its excessive cost.

Bullet Train 1964

On October 1, 1964, Emperor Hirohito inaugurated the bullet train that revolutionized the history of transportation in the world. The Tōkaidō line of the shinkansen was put into operation, a bullet train that then became the fastest in the world, capable of reaching 210 km / h, the “super express of dreams”.

Its operation is based on the principle of magnetic repulsion, capable of creating a powerful magnetic field that acts between the train cars and the track itself.

The Maglev has a price: $ 100 billion. The train will run 80% of the way through tunnels. And they will be few compared to the Tokyo-Osaka line scheduled for 2045, which will reduce the current three hours between the two large cities of the country to one hour and seven minutes.
