Bose wave radio adult dating
We’ve all heard of the epic battles between Edison and Tesla and Westinghouse, and even with the benefit of more than a century of hindsight it’s hard to tell who did what to whom.
But another conflict was brewing at the turn of 19th century, this time between an Indian polymath and an Italian nobleman, and it would determine who got credit for laying the foundations for the key technology of the 20th century – radio.
The device was called a because of the clumping action and was used as rectifiers in all the early practical wireless receivers, despite its operation being not well-understood. Early coherers had a problem, though – the filings stayed stuck together after the signal had passed.
Bose recognized early on that shorter wavelengths would make it easier to explore the properties of radio waves that were similar to light, like reflection, refraction, and polarization.
The invited guests were amazed by the demonstration that Adrisya Alok, or “Invisible Light” as Bose would summarize it in a later essay, could pass through walls, doors, and in a particularly daring feat of showmanship, through the body of the Lieutenant Governor of Bengal.
Bose’s wireless demonstration was remarkable for a couple of reasons.
First, it took place two years before Marconi’s first public demonstrations of wireless telegraphy in England.
Where Marconi was keenly interested in commercializing radio, Bose’s interest was purely academic; in fact, Bose flatly refused to patent nearly all of the inventions that would spring from his tiny workshop, on the principle that ideas should be shared freely.

To do so, he invented almost all the basic components of microwave systems – waveguides, polarizers, horn antennas, dielectric lenses, parabolic reflectors, and attenuators.
