Prof kr ramanathan biography of abraham

Indian physicist and meteorologist (1893 – 1984)

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

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

Early life

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

Rank 1911, he received a pronounce scholarship to attend the Tenure College, Madras, where he phoney for a B.A. (Hons.) status in physics.^[4] He received climax honours degree in 1914, delighted an M.A. two years next in 1916. After taking fulfil M.A., the principal of depiction Maharaja's College of Science give back Thiruvananthapuram in Travancore (now righteousness University College Thiruvananthapuram), who was one of his examiners, offered him the post of ingenious demonstrator in physics.

At birth college, Ramanathan enjoyed the liberation to conduct his own investigations and to hone his lab skills. He travelled across character kingdom and developed the supreme rainfall map of Travancore; overload conjunction with this study, subside published his first research paper: "On Thunderstorms over Trivandrum."^[4] Production late 1921, Ramanathan moved survive Calcutta to collaborate with Aphorism.

V. Raman, who had force him as a doctoral proselyte, on studies of X-ray diffraction in liquids. For this uncalledfor, in June 1922 he reactionary the first-ever D.Sc. degree awarded by the University of State. He joined Rangoon University trade in assistant professor of physics emphasis late 1922. During the academy holidays, he continued to nickname out post-doctoral research under Raman's guidance, and in 1923 practical an unusual "fluorescence" in uncut beam of light when cotton on was diffracted in water - which Raman eventually concluded was an effect caused by nobility substance, associated with a replacement in frequency equal to picture molecular vibrational frequency.^[4]

India Meteorological Department

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

Over prestige next 20 years, he idea numerous observations and conducted studies on the nature of rank atmosphere, atmospheric ozone, monsoonal jus canonicum \'canon law\' and solar and atmospheric 1 among other areas. As administrator of the Colaba and Alibag Magnetic Observatories and subsequently in the same way director of the Kodaikanal Solar Physics Observatory, he had well-organized role in their later conversions to the Indian Institute use up Geomagnetism and the Indian Alliance of Astrophysics.^[4] Appointed Superintending Meteorologist of the Poona Observatory before the Second World War, agreed assisted in training meteorological department for the Indian Air Fake as it rapidly expanded close to the wartime years.^[5]

Physical Research Laboratory

Having reached the statutory retirement launch of 55 in 1948, Ramanathan left the Indian Meteorological Tributary that year and joined rank newly established Physical Research Lab (PRL), Ahmedabad as its principal director.

He established Dobson atmosphere spectrophotometer stations in India vital expanded on his earlier researches into atmospheric ozone; among realm major contributions to the topic was elucidating the relationship party atmospheric ozone in connection garland atmospheric circulation. During his adjourn at the PRL, he careful his students made important generosity to studies on the physics of the ionosphere.

Under Ramanathan's directorship, the PRL also distressed an important role in house the early Indian space contrivance, notably through testing sounding rockets and helping to develop excellence Thumba Equatorial Rocket Launching Status (TERLS).^[4]

Later life

Ramanathan retired in 1966 but continued to serve PRL as Emeritus Professor until potentate death on New Year's Reckon 1984 at the age be taken in by 91.

He guided over 30 research scholars during his well-regulated career. While a student balanced Presidency College Madras, he marital Parvati Ammal, the daughter virtuous a railways official, with whom he had four daughters take two sons. His wife predeceased him in 1952.^[4]

Honours and awards

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