    Famous South Asian physicist, cosmologist J N Islam died


    What was his actual identity? Was he a mathematician, physicist or cosmologist? In a word, he is Professor Jamal Nazrul Islam, renowned as J N Islam to the cosmologist of Europe and USA. Professor Emeritus of Chittagong University, Bangladesh Dr Jamal Nazrul Islam passed away at the age of 74 at a private hospital in Chittagong late on Friday, due to suffering from diabetes and heart diseases.

    Jamal Nazrul Islam was born on Jan 24, 1939 in Jhenaidah city of British India. He was raised in Kolkata along with his family. He studied Bachelor of Science Degree in Mathematics from Calcutta University. He passed his Senior Cambridge at present O-Levels and his Higher Senior Cambridge at present A-Levels from Lawrence College in Marit, West Pakistan. He graduated with an honors degree again from Trinity College in Cambridge.

    He got his Honors and Masters in Functional Mathematics and Theoretical Physics from the Cambridge University and was later awarded Doctorate (PhD) in Physics. Dr Islam worked in the Institute of Theoretical Astronomy in Cambridge from 1967 to 1971. He was also a faculty member at the King’s College (London) from 1973-74 following his research in the California Institute of Technology and Washington University. He was also a faculty at the City University of London from 1978-84.

    In 1984, he returned at Bangladesh and joined the Chittagong University and later retired from there. In 1971, He had written to the Prime Minister of England influence to halt Pakistani Army attacks on East Pakistan, now Bangladesh.
    He wrote numerous books to cheer research conducted in Bengali. He was bestowed the one of uppermost award of Bangladesh, Ekushey Padak in 2001, for his exploration of science in mother tongue Bengali. He acknowledged the Bangladesh Science Academy Gold Medal in 1985.

    From 1983 across the globe, Scientists were enthused by one of his publications ‘The Ultimate Fate of The Universe’. It was interpreted in Japanese, French and many other languages. According to New Scientist (New Scientist: 29 Sep 1983), 'J N Islam describes the modern cosmologist's view of the cosmic crystal ball with vigor, succinctness and directness. The Ultimate Fate of the Universe takes as its basic theme the evolutionary fate of big-bang cosmological towards which they ate directed-either with a whimper or a crunch depending a crunch a depending on whether the missing mass is missing or not.' Journal of the Royal Astronomical Society of Canada (Vol.78, NO.591/DEC, P. 267, 1984) refers that, 'Islam's explanation of the birth, evolution and death of stars is valuable to his discussion and leads him into the realm of white dwarfs, neutron stars and black holes.'

    Some of his other scientific works were Classical General Relativity, Rotating Fields in General Relativity, and An Introduction to Mathematical Cosmology, Sky and Telescope. An Introduction to Mathematical Cosmology provides a concise introduction to the mathematical aspects of the origin, structure and evolution of the universe. Introduction to Mathematical Cosmology begins with a brief overview of observational and theoretical cosmology, along with a short introduction to general relativity. It then goes onto discuss Friedmann models, the Hubble constant and deceleration parameter, singularities, the early universe, inflation, quantum cosmology and the distant future of the universe. This contains sarigorous derivation of the Robertson–Walker metric. It also discusses the limits to the parameter space through various theoretical and observational constraints, and presents a new inflationary solution for a sixth degree potential.

    In Personal life, he was an ardent Nobel Laureate Rabindranath Tagore fan and spoke Bangla with a perfect accent. He never liked to use computer and calculator for his scientific research. Bangla Academy has published some of his popular science books and they were bestsellers.

    RIP Dr J N Islam, Thanks for your excellent research on Cosmology!
