In 1825, British inventor William Sturgeon showed a device that placed the basics for large-scale electronic communications, which is the electromagnet. Sturgeon demonstrated the power of his invention by lifting nine pounds with a seven-ounce piece of iron wrapped with wires through which the current of a single cell battery was sent. This was the beginning of using energy that for making practical and handy machines and laid the foundations for an important electronic communications. Years later Joseph Henry made a far more advance version of the electromagnet that introduced the electric telegraph. Later on other scientists where eager on creating a wireless telegraphy, in 1888 German physicist Heinrich Hertz made the sensational discovery of radio waves, a form of electromagnetic radiation. Italian born Guglielmo Marconi was fascinated by Hertz’s discovery, and realised that if radio waves could be transmitted and detected over
Telegraphy and the radio, two incredible inventions that advanced humanity from the old world in which humans were living in a hole of slow communicative contact with the rest of the world.
Many might ask the reasons for inventing telegraphy and of course the radio. Scientists love to explore new things, and discover fascinating things around the universe. They carry the sense of curiosity and exploration that gives them many new ideas to think off. Inventors like Sturgeon and Marconi might have ask themselves the same question, but one thing for sure that both of them wanted to create a bond of unity in communication. The reasons are simple by building telegraphy on every corner of the earth, civilizations would connect to each other’s, and information would be delivered in a fast trail without the need of other means of transportation. But other might argue differently, that telegraphy was made for warfare rather then i
