Picture trying to talk to someone thirty miles away with no phone, no internet, and no wires. Sounds not possible, right? In 1899, a young Italian inventor named Guglielmo Marconi proved it could be done. On March 27, he sent wireless radio signals across the English Channel. The stretch of water between England and France. Before Marconi, people sent long-distance messages using telegraph wires strung across the land. If the wire broke, the message stopped. Ships at sea had no way to call for help at all. Marconi believed he could send signals through the air using invisible waves called radio waves. Many scientists told him it would never work. He built his own equipment in his parents' attic and started testing. When his signal with success crossed the English Channel, the world paid attention. Within two years, Marconi sent a message across the entire Atlantic Ocean. His invention changed all things. Ships could finally call for help in emergencies. News could travel faster than ever before. Radio broadcasts in time brought music and stories into homes around the world. Every time you use Wi-Fi, listen to the radio. Make a phone call, you are using technology that started with Marconi's big idea.
