Nikhil Ranjan Sen
Nikhil Ranjan Sen (23 May 1894 – 13 January 1963) was an Indian-Bengali scientist who was a pioneer in the field of general relativity and called the father of applied mathematics in India. He received his PhD from Humboldt University of Berlin under the supervision of Max von Laue, thus becoming the first Indian to get a doctorate in relativity. Sen also worked on cosmogony, fluid dynamics, potential theory and probability, and founded the first fluid dynamics laboratory in India. He pioneered the study of ballistics and missiles in India and was also an advocate for science education in the Bengali language. His Bengali-language book titled "Soura Jagat" (The Solar System) was published by Visva-Bharati in 1949. Edited by Subodh Sengupta and Anjali Bose, "Sansad Bengali Charitavidhan", Volume I, Sahitya Sangsad, Kolkata, August 2016, p. 355, Early life and education Nikhil Ranjan Sen was born on 23 May 1894 in Dhaka, the youngest of their four sons and four daughters of K ...

Meghnad Saha
Meghnad Saha (6 October 1893 – 16 February 1956) was an Indian astrophysicist and politician who helped devise the theory of Thermal ionization, thermal ionisation. His Saha ionization equation, Saha ionisation equation allowed astronomers to accurately relate the Stellar classification, spectral classes of stars to their actual temperatures. Biography Meghnad Saha was born on 6 October 1893 to a lower-caste Bengali Hindu family in the village of Kaliakair Upazila, Sheoratali in Gazipur District, Gazipur, then part of the Dhaka Division, Dacca district of the Bengal Presidency (now Bangladesh). He was the fifth of eight children born to Jagannath Saha, a poor shopkeeper, and his wife, Bhubaneshwari Devi. Due to the superstitious religious ideologies of the orthodox haughty Brahmins of the time and his childhood and career experiences of casteism, Saha developed a hatred for Hinduism from a young age. During his youth, he was forced to leave Dhaka Collegiate School because h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subrahmanyan Chandrasekhar
Subrahmanyan Chandrasekhar (; 19 October 1910 – 21 August 1995) was an Indian Americans, Indian-American theoretical physicist who made significant contributions to the scientific knowledge about the structure of stars, stellar evolution and black holes. He was awarded the 1983 Nobel Prize in Physics along with William Alfred Fowler, William A. Fowler for theoretical studies of the physical processes of importance to the structure and evolution of the stars. His mathematical treatment of stellar evolution yielded many of the current theoretical models of the later evolutionary stages of massive stars and black holes. Many concepts, institutions and inventions, including the Chandrasekhar limit and the Chandra X-ray Observatory, Chandra X-Ray Observatory, are named after him. Chandrasekhar worked on a wide variety of problems in physics during his lifetime, contributing to the contemporary understanding of stellar structure, white dwarfs, stellar dynamics, stochastic process, r ...

Heisenberg
Werner Karl Heisenberg (; ; 5 December 1901 – 1 February 1976) was a German theoretical physicist, one of the main pioneers of the theory of quantum mechanics and a principal scientist in the German nuclear program during World War II. He published his Umdeutung paper, ''Umdeutung'' paper in 1925, a major reinterpretation of old quantum theory. In the subsequent series of papers with Max Born and Pascual Jordan, during the same year, his matrix mechanics, matrix formulation of quantum mechanics was substantially elaborated. He is known for the uncertainty principle, which he published in 1927. Heisenberg was awarded the 1932 Nobel Prize in Physics "for the creation of quantum mechanics". Heisenberg also made contributions to the theories of the Fluid dynamics, hydrodynamics of turbulent flows, the atomic nucleus, ferromagnetism, cosmic rays, and subatomic particles. He introduced the concept of a wave function collapse. He was also instrumental in planning the first West Germa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Partition Of India
The partition of India in 1947 was the division of British India into two independent dominion states, the Dominion of India, Union of India and Dominion of Pakistan. The Union of India is today the Republic of India, and the Dominion of Pakistan is the Islamic Republic of Pakistan and the People's Republic of Bangladesh. The Partition (politics), partition involved the division of two provinces, Bengal and the Punjab Province (British India), Punjab, based on district-wise Hindu or Muslim majorities. It also involved the division of the British Indian Army, the Royal Indian Navy, the Indian Civil Service, the History of rail transport in India, railways, and the central treasury, between the two new dominions. The partition was set forth in the Indian Independence Act 1947 and resulted in the dissolution of the British Raj, or Crown rule in India. The two self-governing countries of India and Pakistan legally came into existence at midnight on 14–15 August 1947. The partiti ...
