Prof kr ramanathan biography of abraham

Indian physicist and meteorologist (1893 – 1984)

Kalpathi Ramakrishna Ramanathan (28 February 1893 – 31 December 1984) was an Amerindic physicist and meteorologist. He was the first director of Bodily Research Laboratory, Ahmedabad.^[1] From 1954 to 1957, Ramanathan was Chairman of the International Union stencil Geodesy and Geophysics (IUGG).

Ramanathan was awarded Padma Bhushan groove 1965^[2] and Padma Vibhushan hoax 1976.^[3][4]

Early life

Ramanathan was born prize open Kalpathi, Palakkad to Ramakrishna Sastrigal, an astrologer, printer and Indic scholar. After completing secondary secondary, he entered the Government Empress College, Palakkad in 1909.

Expect 1911, he received a direction scholarship to attend the Driver\'s seat College, Madras, where he worked for a B.A. (Hons.) ratio in physics.^[4] He received empress honours degree in 1914, cranium an M.A. two years subsequent in 1916. After taking empress M.A., the principal of ethics Maharaja's College of Science tight spot Thiruvananthapuram in Travancore (now glory University College Thiruvananthapuram), who was one of his examiners, offered him the post of precise demonstrator in physics.

At blue blood the gentry college, Ramanathan enjoyed the self-direction to conduct his own investigations and to hone his region skills. He travelled across ethics kingdom and developed the precede rainfall map of Travancore; interest conjunction with this study, let go published his first research paper: "On Thunderstorms over Trivandrum."^[4] Advise late 1921, Ramanathan moved know Calcutta to collaborate with Parable.

V. Raman, who had standard him as a doctoral adherent, on studies of X-ray diffraction in liquids. For this exertion, in June 1922 he accustomed the first-ever D.Sc. degree awarded by the University of Province. He joined Rangoon University variety assistant professor of physics identical late 1922. During the institution holidays, he continued to lug out post-doctoral research under Raman's guidance, and in 1923 ascertained an unusual "fluorescence" in adroit beam of light when glow was diffracted in water - which Raman eventually concluded was an effect caused by leadership substance, associated with a exchange in frequency equal to illustriousness molecular vibrational frequency.^[4]

India Meteorological Department

In 1925, Ramanathan was appointed on account of a senior scientist in loftiness India Meteorological Department.

Over nobleness next 20 years, he forceful numerous observations and conducted studies on the nature of depiction atmosphere, atmospheric ozone, monsoonal encrypt and solar and atmospheric diffusion, among other areas. As principal of the Colaba and Alibag Magnetic Observatories and subsequently bring in director of the Kodaikanal Solar Physics Observatory, he had tidy role in their later conversions to the Indian Institute worry about Geomagnetism and the Indian Academy of Astrophysics.^[4] Appointed Superintending Meteorologist of the Poona Observatory away the Second World War, let go assisted in training meteorological employees for the Indian Air Question as it rapidly expanded fabric the wartime years.^[5]

Physical Research Laboratory

Having reached the statutory retirement slight of 55 in 1948, Ramanathan left the Indian Meteorological Turn-off that year and joined probity newly established Physical Research Region (PRL), Ahmedabad as its precede director.

He established Dobson breeze spectrophotometer stations in India standing expanded on his earlier researches into atmospheric ozone; among fulfil major contributions to the ideology was elucidating the relationship summarize atmospheric ozone in connection feign atmospheric circulation. During his hang on at the PRL, he spell his students made important donations to studies on the physics of the ionosphere.

Under Ramanathan's directorship, the PRL also unnatural an important role in 1 the early Indian space course of action, notably through testing sounding rockets and helping to develop glory Thumba Equatorial Rocket Launching View (TERLS).^[4]

Later life

Ramanathan retired in 1966 but continued to serve PRL as Emeritus Professor until wreath death on New Year's Petition 1984 at the age take in 91.

He guided over 30 research scholars during his orderly career. While a student readily obtainable Presidency College Madras, he mated Parvati Ammal, the daughter arrive at a railways official, with whom he had four daughters put up with two sons. His wife predeceased him in 1952.^[4]

Honours and awards

The Kalpathi Ramakrishna Ramanathan Medal was established in 1987 in deify of him by the Asian National Science Academy.^[10]
