  Jagdish Chandra Bose Summary
Bose was deeply patriotic, and his encouragement of research in the universities and in the Bose Research Institute, which he founded in Calcutta in 1917, was a reflection of his conviction that Indians must add scientific skills to their great religious tradition.
Jagdish Chandra Bose (Bengali: জগদীশ চন্দ্র বসু Jôgdish Chôndro Boshu) (November 30, 1858 – November 23, 1937) was a Bengali physicist from Undivided India, who pioneered the investigation of radio and microwave optics.
Bose’s place in history has now been re-evaluated, and he is credited with the invention of the first wireless detection device and the discovery of millimetre length electromagnetic waves and considered a pioneer in the field of biophysics.

 J.C. Bose: 60 GHz in the 1890s
Bose's experiments were carried out at the Presidency College in Calcutta, although for demonstrations he developed a compact portable version of the equipment, including transmitter, receiver and various microwave components.
Bose was able to measure the wavelength of his radiation with a reflecting diffraction grating made of metal strips [7].
Bose noted that the junction does not obey Ohm's law, and that there is a knee in the curve at approximately 0.45 volts; the junction becomes most effective at detection of short wavelength radiation when the corresponding bias voltage is applied.

In addition to his work on star degeneration, Chandrasekhar contributed important theorems on the stability of cosmic masses in the presence of gravitation, rotation, and magnetic fields; this work proved to be crucial for the understanding of the spiral structure of galaxies.
Bose turned his attention from electromagnetic waves to response phenomena in plants by the end of the 19th century.
Bose's research on response in living and non-living led to some significant findings: in some animal tissues like muscles, stimulation produces change in form as well as electrical excitation, while in other tissues (nerves or retina), stimulation by light produces electric changes only but no change of form.

Bose also developed equipment for generating, transmitting, and receiving radio waves and used it to demonstrate conclusively the waves’ properties such as reflection, total reflection, refraction, double refraction, and polarization.
Bose also experimented with galena to form an early type of semiconductor diode, which may be used as a detector of electromagnetic waves.
Bose traveled frequently to Europe and the United States on various scientific missions and gave lectures on electromagnetic waves, the effects of electromagnetic waves on living and nonliving matter, and plant physiology.

Jagdish Chandra Bose, a distinguished Indian scientist, announced his discovery to an astonished world in 1900.
Born on 30th November, 1858, in Mymensingh, Bengal, Jagdish Chandra Bose was fascinated by the world and its phenomena around him from a very early age.
His surprising anti-patent policy is best understood through his humility: Bose firmly believed and proclaimed that his work was not new, that the ancient sages and saints of India knew these undiscovered secrets of nature thousands of years ago and he was merely re-discovering them for himself.
