• Invention of Radio (1897): Guglielmo Marconi, an Italian inventor, demonstrated the feasibility of wireless communication. He successfully sent and received the first radio signals in 1895. In the early 20th century, Marconi began working on transmitting signals across the Atlantic to compete with cable-based communication. In 1901, he succeeded in sending the first wireless signal across the ocean from Poldhu, Cornwall, UK to Signal Hill in St. John's, Newfoundland (now part of Canada). The distance between the two locations was about 3500 km. The signal Marconi received was three click sounds, corresponding to the letter 'S' in Morse code. In 1909, Marconi and Karl Ferdinand Braun jointly received the Nobel Prize in Physics for their significant contributions to the development of wireless communication technology.
• Invention of the Smartphone (2007): In 2007, Apple introduced the first touchscreen mobile phone, which pioneered the production of touchscreen mobile devices. These devices integrated GPS, compass, voice recording, camera, maps, and a web browser, along with an app store allowing users to download and use their favorite apps. Today, smartphones are widely used as communication tools, featuring modern design and functionality.
• Invention of the Airplane (1903): The world's first successful airplane flight was achieved by brothers Orville and Wilbur Wright. On December 17, 1903, their aircraft flew 40 meters in 12 seconds, becoming the first successful powered flight in history, named the Flyer I. The Flyer had a wingspan of about 12 meters and weighed over 300 kg. It featured a two-wing design, with the pilot lying on the lower wing.
