Bibha Chowdhuri
Bibha Chowdhuri (3 July 1913 – 2 June 1991) was an Indian physicist. She worked on particle physics and cosmic rays. The IAU has re-christened the star HD 86081 as Bibha (a yellow-white dwarf star in the constellation Sextans south of the celestial equator) after her. Early life and education Chowdhuri was born in Kolkata. Her father, Banku Behari Chowdhuri, was a doctor and her mother Urmila Devi was daughter of a Brahmo Samaj Missionary. She was the third eldest child, and had four sisters and a brother. Her aunt, Nirmala Devi, was married to Sir Nilratan Sircar. Her mother's family were adherents of the Brahmo Samaj movement. Her sister, Roma Chowdhuri, went on to become a teacher at Brahmo Balika Shikshalaya. Bibha studied physics at Rajabazar Science College of Calcutta University and was the only woman to complete M.Sc. degree in the year 1936. She joined the Bose Institute after graduating in 1939 and worked with Debendra Mohan Bose. Together, they experimentally ob ...

Kolkata
Kolkata (, or , ; also known as Calcutta , the official name until 2001) is the capital of the Indian state of West Bengal, on the eastern bank of the Hooghly River west of the border with Bangladesh. It is the primary business, commercial, and financial hub of Eastern India and the main port of communication for North-East India.

Kolar Gold Fields
Kolar Gold Fields (K.G.F.) is a mining region in K.G.F. taluk (township), Kolar district, Karnataka, India. It is headquartered in Robertsonpet, where employees of Bharat Gold Mines Limited (BGML) and BEML Limited (formerly Bharat Earth Movers Limited) and their families live. K.G.F. is about from Kolar, from Bengaluru, capital of Karnataka. Over a century, the town has been known for gold mining. The mine closed on 28 February 2001 due to a fall in gold prices, despite gold still being present there. One of India's first power-generation units was built in 1889 to support mining operations. The mine complex hosted some particle physics experiments between the 1960s and 1992. History The history of the Kolar Gold Fields was compiled by Fred Goodwill, superintendent of the Police, Maldives and Kolar Gold Fields. Goodwill's studies were published in the ''Quarterly Journal of the Mythic Society'' and elsewhere. The Jain Western Gangas Dynasty founded Kolar in the second ...

Nobel Prize
The Nobel Prizes ( ; sv, Nobelpriset ; no, Nobelprisen ) are five separate prizes that, according to Alfred Nobel's will of 1895, are awarded to "those who, during the preceding year, have conferred the greatest benefit to humankind." Alfred Nobel was a Swedish chemist, engineer, and industrialist most famously known for the invention of dynamite. He died in 1896. In his will, he bequeathed all of his "remaining realisable assets" to be used to establish five prizes which became known as "Nobel Prizes." Nobel Prizes were first awarded in 1901. Nobel Prizes are awarded in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace (Nobel characterized the Peace Prize as "to the person who has done the most or best to advance fellowship among nations, the abolition or reduction of standing armies, and the establishment and promotion of peace congresses"). In 1968, Sveriges Riksbank (Sweden's central bank) funded the establishment of the Prize in Economi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extensive Air Shower
An air shower is an extensive (many kilometres wide) cascade of ionized particles and electromagnetic radiation produced in the atmosphere when a ''primary'' cosmic ray (i.e. one of extraterrestrial origin) enters the atmosphere. When a particle, which could be a proton, a nucleus, an electron, a photon, or (rarely) a positron, strikes an atom's nucleus in the air it produces many energetic hadrons. The unstable hadrons decay in the air speedily into other particles and electromagnetic radiation, which are part of the particle shower components. The secondary radiation rains down, including x-rays, muons, protons, antiprotons, alpha particles, pions, electrons, positrons, and neutrons. The dose from cosmic radiation is largely from muons, neutrons, and electrons, with a dose rate that varies in different parts of the world and based largely on the geomagnetic field, altitude, and solar cycle. Airline crews receive more cosmic rays if they routinely work flight routes that take ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muon
A muon ( ; from the Greek letter mu (μ) used to represent it) is an elementary particle similar to the electron, with an electric charge of −1 '' e'' and a spin of , but with a much greater mass. It is classified as a lepton. As with other leptons, the muon is not thought to be composed of any simpler particles; that is, it is a fundamental particle. The muon is an unstable subatomic particle with a mean lifetime of , much longer than many other subatomic particles. As with the decay of the non-elementary neutron (with a lifetime around 15 minutes), muon decay is slow (by subatomic standards) because the decay is mediated only by the weak interaction (rather than the more powerful strong interaction or electromagnetic interaction), and because the mass difference between the muon and the set of its decay products is small, providing few kinetic degrees of freedom for decay. Muon decay almost always produces at least three particles, which must include an electron o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brahmo Samaj
Brahmo Samaj ( bn, ব্রহ্ম সমাজ, Brahmô Sômaj, ) is the societal component of Brahmoism, which began as a monotheistic reformist movement of the Hindu religion that appeared during the Bengal Renaissance. It was one of the most influential religious movements in India and made a significant contribution to the making of modern India. It was started at Calcutta on 20 August 1828 by Raja Ram Mohan Roy and Dwarkanath Tagore as reformation of the prevailing Brahmanism of the time (specifically Kulin practices) and began the Bengal Renaissance of the 19th century pioneering all religious, social and educational advance of the Hindu community in the 19th century. Its Trust Deed was made in 1830 formalising its inception and it was duly and publicly inaugurated in January 1830 by the consecration of the first house of prayer, now known as the Adi Brahmo Samaj. From the ''Brahmo Samaj'' springs Brahmoism, the most recent of legally recognised religions in India an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sir Nilratan Sircar M.A. M.D. D.Sc. (1 October 1861 – 18 May 1943) was an Indian doctor, educationist, philanthropist and swadeshi entrepreneur. He was awarded honorary DCL by University of Oxford & LL.D by University of Edinburgh. He was a renowned figure in promoting Science and Technology education in contemporary India. Early life Son of Nandalal Sircar, a native of Jaynagar, he was born in the house of his maternal uncle in Netra village of South 24 Parganas district, on 1 October 1861. His father came from an impoverished family in Jessore and later settled in Jaynagar. However, as his mother often suffered from ill health, Sircar and his siblings spent much of their growing years with their maternal family in Netra village and subsequently moved there. His mother died while he was still a child from what was later believed to be cancer. Sircar was reported to have shared with grandchildren that it was this early loss of his mother to an unknown disease that led him ...
