Speaking at the Bikrampur Conference inBose said: At that time, sending children to English schools was an aristocratic status symbol. In the vernacular school, to which I was sent, the son of the Muslim attendant of my father sat on my right side, and the son of a fisherman sat on my left.

They were my playmates. I listened spellbound to their stories of birds, animals and Ngn research papers creatures. Perhaps these stories created in my mind a keen interest in investigating the workings of Nature.

When I returned home from school accompanied by my school fellows, my mother welcomed and fed all of us without discrimination. I never realised that there existed a 'problem' common to the two communities, Hindus and Muslims.

Xavier's School at Kolkata. Inhe passed the Entrance Examination equivalent to school graduation of the University of Calcutta and was admitted to St. Xavier's, Bose came in contact with Jesuit Father Eugene Lafontwho played a significant role in developing his interest in natural sciences.

However, his father, a civil servant himself, cancelled the plan. However, he had to quit because of ill health.

They met in London and became intimate friends. His receiver left used a galena crystal detector inside a horn antenna and galvanometer to detect microwaves. Bose invented the crystal radio detector, waveguidehorn antennaand other apparatus used at microwave frequencies.

The Scottish theoretical physicist James Clerk Maxwell mathematically predicted the existence of electromagnetic radiation of diverse wavelengths, but he died in before his prediction was experimentally verified.

Between andGerman physicist Heinrich Hertz published the results of his experiments on electromagnetism, which showed the existence of electromagnetic waves in free space.

Subsequently, British physicist Oliver Lodgewho had also been researching electromagnetism, conducted a commemorative lecture in August after Hertz's death on the quasi-optical nature of "Hertzian waves" radio waves and demonstrated their similarity to light and vision including reflection and transmission at distances up to 50 metres.

Lodge's work was published in book form and caught the attention of scientists in different countries, including Bose in India. He realised the disadvantages of long waves for studying their light-like properties.

Bose wrote in a Bengali essay, Adrisya Alok Invisible Light"The invisible light can easily pass through brick walls, buildings etc. Therefore, messages can be transmitted by means of it without the mediation of wires.

In Decemberthe London journal Electrician Vol. At that time, the word coherer, coined by Lodge, was used in the English-speaking world for Hertzian wave receivers or detectors.

The Electrician readily commented on Bose's coherer. The Englishman 18 January quoted from the Electrician and commented as follows: Bose planned to "perfect his coherer" but never thought of patenting it.

Bose went to London on a lecture tour in and met Italian inventor Guglielmo Marconiwho had been developing a radio wave wireless telegraphy system for over a year and was trying to market it to the British post service.

In an interview, Bose expressed his disinterest in commercial telegraphy and suggested others use his research work. InBose announced the development of a "iron-mercury-iron coherer with telephone detector" in a paper presented at the Royal SocietyLondon.

A friend in the US persuaded him to take out a US patent on his detector but he did not actively pursue it and allowed it to lapse. InBose described to the Royal Institution in London his research carried out in Kolkata at millimetre wavelengths. In fact, he had anticipated the existence of P-type and N-type semiconductors.

His major contribution in the field of biophysics was the demonstration of the electrical nature of the conduction of various stimuli e.Jun 01,  · With the China Action Plan of Promoting the Deployment of the Internet Protocol (IPv6) issued and published by the General Office of the CPC Central Committee and the General Office of the State Council by the end of Following is the methodology through each step for a single application category (in this case, Internet video) where the estimation process is illustrated.
