Bose wave radio adult dating
In 1885, a 27-year old Jagadish Chandra Bose returned to his native India from England, where he had been studying natural science at Cambridge.
Originally sent there to study medicine, Bose had withdrawn due to ill-health exacerbated by the disagreeable aroma of the dissection rooms.
Some of Bose’s most important work in radio concerned detection of electromagnetic waves.
Early wireless pioneers had discovered that electromagnetic waves could be rectified by fine metal particles contained in a tube between metal conductors; the electrical energy would cause the particles to clump together and become conductive.
While academics were busy uncovering the mysteries of electromagnetism, bands of entrepreneurs were waiting to pounce on the pure science and engineer solutions to problems that didn’t even exist yet, but could no doubt turn into profitable ventures.But in those 24 square feet, equipped with instruments of his own design and paid for at his expense, Bose would work wonders and begin to engineer the embryonic field of radio.At around the time Bose joined Presidency College, Heinrich Hertz was confirming the existence of electromagnetic waves, postulated by James Clerk Maxwell in the 1860s.The 1895 demonstration also used microwave signals instead of the low and medium frequency waves that Marconi and others were working with.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.

Maxwell died before he could demonstrate that electricity, magnetism, and light are all one in the same phenomenon, but Hertz and his spark gap transmitters and receivers proved it.
