The printing press was invented in the 15th century by Johannes  and  perfected over the centuries, but since then it has allowed the serial reproduction of books, magazines, brochures, clothing and other articles equipped with texts and images, through various methods of pressure and inking .
The printing press is used to mass produce books, magazines, pamphlets, brochures, fabrics, garments and many other objects with text and images: quickly, efficiently and economically. This was thanks to a system of mobile plates that, when pressed, could reproduce the same page multiple times, then the next and then the next, until obtaining several sets that, arranged, made up several copies of an entire book. The first book to be made in this way was the Bible.]]> 2020-10-30 22:10:21 UTC https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/878000407 Microwave. perezabadalan301 https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/878064984                 Invented in 1946.

It was discovered in 1946 by accident thanks to engineer Percy Spencer of the Raytheon Corporation, who was testing the device in a radar-related investigation. Without eating or drinking it, pun intended, he realized that a chocolate bar he carried in his pocket melted.
The thing did not stop there because the scientist decided to test that device near other food products, with his surprise that they were cooked thanks to the low-density waves.
His suspicions paid off. Spencer experimented with it with corn seeds. The result? Logical; popcorn appeared. The same thing happened with an egg; it swelled as the temperature rose. His big step was already creating a metal cube and a hole where to introduce the magnetron radiation]]> 2020-10-30 23:07:20 UTC https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/878064984 X-rays. perezabadalan301 https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/878076582                Invented in 1896.

Its history begins with the experiments of the British scientist William Crookes, who in the 19th century investigated the effects of certain gases by inducing certain energy discharges in a vacuum tube and electrodes.
But it was the German physicist Wilhelm Conrad Roentgen, in 1896, who technically discovered them while experimenting with these tubes and a coil in an investigation of the violet fluorescence produced by cathode rays. To test it, he covered that tube with a black cardboard plate in order to reduce the presence of light, although he discovered that there was a small flash from a screen with a platinum-barium cyanide layer that disappeared when the tube was turned off.]]> 2020-10-30 23:18:06 UTC https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/878076582 Touch screen. perezabadalan301 https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/878083577                 Invented in 1983.

Dr. George Samuel Hurst and his research team used a Van de Graff accelerator that was only available at night to research atomic physics at the University of Kentucky.
Tired of the slow progress, the researcher used electrically conductive paper to read a pair of X and Y coordinates, allowing his students to calculate in a few hours what would have taken days. The idea led to the first touch screen for computers. The HP-150 was, in 1983, one of the first commercial computers in the world that had a touch screen. Today almost all mobile phones have capacitive panels that interact with overlapping finger movements. Apple, in 2007, developed a multi-touch system that, without a doubt, laid the first stones of the mobile revolution.]]> 2020-10-30 23:25:24 UTC https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/878083577 Computer mause. perezabadalan301 https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/878094938                Invented in 1981.

It was designed by scientist Douglas Engelbart and Bill English in the 1960s at the Stanford Research Institute, and developed by Xerox PARC. The first model was built by hand in wood. It was patented under the name "X-Y Position Indicator for a Display System".
Despite the hopes placed by its researchers that it would succeed, the apparatus lived for a few years in ostracism. Until Xerox adapted it in 1981 into the Star 8010, the first computer with a mouse included, although it was not until the ill-fated Steve Jobs decided to integrate it into his proposals as an accessory whose manufacture was affordable when it did not take off as a revolutionary peripheral.]]> 2020-10-30 23:37:15 UTC https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/878094938 Photography abrahampc04 https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/879171121 invented in the late nineteenth century
It was another of the most important inventions in history.  It changed the course of painting, also of culture and the way we see and represent both the world and ourselves.  Essential during the late 19th century and throughout the 20th in a sense.  Now, with mobile telephony, photography is everyone's business.  That is why there are those who claim that it no longer exists as such.

Radio was a great invention that sparked the evolution of communications, the media, and even commerce.  This innovative device became a social phenomenon that brought people together.

It was born in the sixties of last century, when the United States created an exclusively military network so that, in the event of a Soviet attack, it could have access to information from anywhere in the country. Already in the eighties, Tim Berners-Lee and scientists from MIT, created HTTP and, later, the World Wide Web, becoming the essential infrastructure of the digital age. It is considered one of the most important inventions in history because it brought about a large-scale change in all areas of society.]]> 2020-11-01 02:26:51 UTC https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/879182744 credit card abrahampc04 https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/879190648 Invented in 1958.
It emerged in the fifties of the 20th century from the hand of the American Ralph Schneider, the founder of Diner’s Club.  With the credit card, the future of the domestic economy changed.

it is intelligence carried out by machines.  In computer science, an ideal "smart" machine is a flexible agent that perceives its environment and takes actions that maximize its chances of success in some goal or task. ]]> 2020-11-01 02:54:05 UTC https://padlet.com/perezabadalan301/icw8hvdmp3l9n7d5/wish/879194986
