Tata Institute of Fundamental Research (TIFR) , Mumbai  was established in June 1945 at the initiative of  Dr. Homi Jehangir Bhabha, an eminent mathematical physicist who had made notable contributions to the field of particles and their interactions in 1930's including the famous Bhabha-Heitler cascade  theory for the development of cosmic ray showers in the atmosphere. The Institute and its various  Centres and Field Stations have a total strength of about 400 scientists working in various disciplines grouped into three major Schools: School of Mathematics, the School of Natural Sciences and the School of Technology and Computer Science. The School of Mathematics has a Centre in Bangalore dedicated to the study of Applied Mathematics. The Homi Bhabha Centre for Science Education at Mumbai, the National Centre for Radio Astrophysics at Pune and the National Centre for Biological Sciences at Bangalore are a part of the School of Natural Sciences. The School of Technology and Computer Science is operating a Centre for Computational Mathematics at Pune. In addition, the Institute has several field stations for observational programs in specific fields, the Giant Meterwave Radio Telescope (GMRT) at Khodad, 80 km north of Pune, the equatorially-mounted cylindrical  Ooty Radio Telescope (ORT)  and the  Cosmic Ray Laboratory (CRL) at Ooty, 250 km south of Bangalore, the High Energy Gamma Ray Observatory (HEGRO) at Pachmarhi, 200 km south of Bhopal, and the Gravitation Laboratory at Gauribidanur, 80 km north of Bangalore. Research in theoretical and experimental physics is a major component of the academic activity at the main campus of the Institute at Mumbai with large groups working in  theoretical physics, astronomy & astrophysics, cosmic ray astrophysics, high energy physics, condensed matter physics & material science and atomic & nuclear physics. The scientists in the Departments of chemical physics and biological sciences use a state of the art FTNMR facility for studies focused on the structure of complex molecules and proteins.

The vision for the development of TIFR was contained in the letter written in 1943 by Homi Bhabha to the eminent industrialist and philanthropist J.R.D. Tata. In this historic letter, Bhabha sought JRD's support "to build in the course of time a School of Physics comparable to the best anywhere". The TIFR started functioning on June 1, 1945 at the Cosmic Ray Research unit set up by Homi Bhabha on the campus of the Indian Institute of Science, Bangalore at the invitation of the then I.I.Sc. Director, Nobel Laureate C.V. Raman. Within 6 months, the TIFR shifted to Kenilworth, a bungalow on Pedder Road in Central Bombay and then to the Old Yacht Club, near the Gateway of India, in 1949. The new 15-acre campus in Navy Nagar in Colaba in southern Bombay overlooking the Arabian sea, specially designed to provide excellent ambience and facilities for mathematicians and physicists, both theoretical and experimental, was formally inaugurate by Prime Minister Jawaharlal Nehru on January 15, 1962.(

National Centre for Radio Astrophysics (NCRA), Pune, is one of the Centres of the School of Natural Sciences of the Tata Institute of Fundamental Research, Mumbai. Started in 1963, the Radio Astronomy group at TIFR built the 550 m long, 50 m wide cylindrical radio telescope  (ORT) at Ooty in late 1960's. The ORT exploited the low latitude (11.4 N) and the mountain topography in the Nilgiri mountains to save on constructions costs. Using the technique of lunar occultation, a unique database of radio sizes for 700 sources with few arc second resolution at meter wavelengths was obtained with the ORT. Several studies using the techniques of interplanetary and interstellar scintillation, observations of pulsars and radio recombination lines and searches for lines of deuterium and highly red-shifted hydrogen were conducted with the ORT over nearly two decades. Recently, the Radio Astronomy group, now located at the NCRA, Pune, on the campus of the University of Pune, has constructed the Giant Meterwave Radio Telescope (GMRT) at Khodad, 80 km north of Pune, which became operational in 1998. The GMRT is the world's largest synthesis telescope at wavelengths longer than 21 cm. On-going studies at the GMRT include observations on highly red-shifted 21cm hydrogen absorption lines, diffuse radio emission from clusters of galaxies, discovery of new galactic supernova remnants and multi-frequency pulsar observations. It is proposed to organize an excursion to GMRT and nearby interesting places on  Sunday, Aug 7, 2005.(
