  4. 4. Narlikar was born in Kolhapur, India on July 19, 1938. His father, Vishnu Vasudev Narlikar, was a mathematician who served as a professor and later as the Head of the Department of Mathematics at Banaras Hindu University, Varanasi. Jayant's mother, Sumati Narlikar, was a scholar of Sanskritlanguage. Jayant studied in Kendriya Vidyalaya Banaras (till class 12) and Banaras Hindu University (12th Onwards) campus, Varanasi. Career.Narlikar received his Bachelor of Science degree from Banaras Hindu University in 1957. He then began his studies at Fitzwilliam House, Cambridge University in England, where he received a B.A. in mathematics in 1959 and was Senior Wrangler.[2] This appears to have been the first time, and perhaps the only time, that a student was Senior Wrangler who was a non-collegiate member of the University at the time. In 1960, he won the Tyson Medal for astronomy. During his doctoral studies at Cambridge, he won the Smith’s Prize in 1962. After receiving his Ph.D. in 1963 under the guidance of Fred Hoyle, he served as a Berry Ramsey Fellow at King's College in Cambridge and earned an M.A. in astronomy and astrophysics in 1964. He continued to work as a Fellow at King's College until 1972. In 1966, Fred Hoyle established the Institute of Theoretical Astronomy in Cambridge, and Narlikar served as the founder staff member of the institute during 1966-72. Narlikar is internationally known for his work in cosmology, especially in championing models alternative to the popular Big Bang model. During 1994-1997, he was the President of the Cosmology Commission of the International Astronomical Union.Narlikar was appointed as the Chairperson of The Advisory Group for Textbooks in Science and Mathematics, the textbook development committee responsible for developing textbooks in Science and Mathematics, published by NCERT, which are used widely as standard textbooks in many Indian schools. biswarup mukherjee (jnv keonjhar). mukherjee_biswarup@yahoo.com
  5. 5. GENERAL INTRODUCTION COMETS ARE LIKE SMALL PLANETS AND THEY REVOLVE ROUND THE SUN. BUT THEY COME FROM AFAR, AND SO THEY APPEAR AFTER YEARS, AND EVEN AFTER CENTURIES. THEN THEY DISAPPEAR.
