What did Jagadish Chandra Bose invent

The history of electronic radio technology is plagued by controversy over who actually invented this thing. The most common answer is the Italian inventor Guglielmo Marconi, but many others have made important discoveries that give them a fair claim to the title.

Here is a rundown of the contenders for the title of father of radio:

  • Marconi: He was the first to successfully demonstrate radio and exploit it commercially. In 1901, Marconi radioed a message across the Atlantic from England to Canada, although the message was weak and consisted of nothing but the letter S, and receipt of the message was not independently acknowledged. Still, Marconi's accomplishment was astounding, and he made many important contributions to the technology and business of radio.

  • Tesla: In 1943, the US Supreme Court ruled that many of Marconi's important patents were invalid because Nikola Tesla had already described the devices covered by Marconi's patents.

    Tesla was a brilliant engineer best known for being the master of alternating current over direct current for power distribution. He publicly demonstrated wireless communication devices as early as 1893. Tesla believed that wireless technology would be used not only for communication but also for power distribution.

  • Lodge: In England, Sir Oliver Lodge built wireless telegraph systems in the mid-1890s.

  • Popov: In Russia, Alexander Stepanovich Popov was demonstrating wireless telegraphic transmissions around the same time as Lodge Lodge.

  • Angry: In India, Sir Jagadish Chandra Bose also demonstrated wireless telegraph transmissions in the early 1890s. Whether these demonstrations took place before, after, or at the same time as other demonstrations by Lodge, Popov and others is controversial.

  • Many other: The list of names of others who carried out important research and made important discoveries in the last decades of the nineteenth century is long: Heinrich Hertz, Edouard Branly, Roberto de Moura, Ernest Rutherford, Ferdinand Braun, Julio Baviera and Reginald Fessenden are just a few of the many people who have made important contributions.

So it seems that no one has a clear claim to be the first to invent radio. Work was done all over the world and discoveries were made every day.

It may be that the best answer is that nobody "invented radio". Radio is a natural phenomenon. It was discovered , Not invented.

What was invented were ways to take advantage of the radio phenomenon by building devices that could generate and modulate radio waves to add information and devices that could receive radio waves and extract the added information.
