There have been many incredible discoveries in human history. Some are simple, while others are extremely complex. For example, a razor blade is a simple invention, but it is the only one that is affordable and used on a daily basis by billions of people. Airplanes and rockets are very complicated inventions that necessitate a great deal of study and highly intelligent people.
Radio has been a part of humanity for many years, but do we really know who came up with this brilliant idea? Many people, I'm sure, would say no.
Electromagnetic wave studies began in the mid-1890s. Guglielmo Marconi, a young man with a keen intellect, was the first to make significant strides in the field. Guglielmo Marconi invented the first long-distance radio communication system.
Of course, there were those with similar intelligence, such as Guglielmo Marconi. In December 1990, Reginald A. Fessenden applied to Guglielmo's accomplishment of becoming the first Canadian to transmit audio messages over a distance of around 1.6 kilometers using electromagnetic waves.
Maybe things would have been different if radio hadn't been invented.
