Inventions that changed the world. Radio
Radio is here to stay.
Data transfer via radio waves is used today not only for long distance communication, television and radio broadcasting, but also for radar, navigation, medicine, criminalistics and many other areas. Alexander Popov is considered the inventor of the radio. On May 7, 1895 at the meeting of the Russian Physical Chemical Society in St. Petersburg Popov demonstrated the functioning of his instrument, which actually became the world's first radio. In 1945 people in the USSR began to celebrate Radio Day each year on May 7. It should be noted that at the same time there were some other scientists to do research in the field of radio communication: Nikola Tesla, Guglielmo Marconi, Thomas Edison, and also Jacob Narkevitch-Iodko from Belarus.
