EMRC, 50 Circus Avenue, Kolkata 700 017. Ph. 91-33-22874869 Fax. 91-33-2289-1373

EMRC St. Xavier’s College, Kolkata is part of a large family of EMRCs spread across India. This family has in fact 18 members, including the head office at New Delhi. The other members are at Srinagar, Roorkee, Patiala, Jodhpur, New Delhi, Ahmedabad, Indore, Sagar, Imphal, Pune, Mysore, Chennai, Madurai, Calicut and two at Hyderabad.

All the centres come under the purview of the university of that particular place. In Hyderabad one is with the Central Institute for English and Foreign Languages (CIEFL) and the other is with Osmania University. It is only the Kolkata EMRC that comes under the purview of St. Xavier’s college.

All funding – both for running expenses and equipment – comes from the University Grants Commission. The coordination of production, telecast and other programme related affairs is done by the Consortium for Educational Communication (CEC), New Delhi. The administration is done by the host university/college.



The Race - A Programme On The Cyclotron

Duration : 22:37    Year : 1987    Code No.13

Many decades back it was discovered that matter was made up of atoms - meaning -indivisible units of matter. As probe improved we found atoms are made of nuclei and electrons. Attacked by stronger tools, the nuclei too revealed their structure - they are made up of nucleons. As probe energies increased to billions of electron volts, we found structure inside the nucleons. Nucleons are made of quarks and gluons. The cyclotron is in the centre of these discoveries. While this is the main use of the cyclotron, the accelerated particles from the cyclotron find important application in our everyday world as well.

Let There Be Light

Duration : 20:43    Year : 1987    Code No.212

The programme starts with an introduction to the nature of light. The idea of Electromagnetic waves and optical part of electromagnetic spectrum are then explained. The initial conflict between wave theory and corpuscular theory of light and the different situations where each is operating is also demonstrated. The scattering of light, the physical principles of interference and diffraction are also explained very lucidly.

Science Jatha

Duration : 10:10    Year : 1987    Code No.220

Science Jatha seeks to bring to the people the message that science has developed tools which can radically change our lives. Science enables utilization of what appears to be elemental forces of nature because it provides knowledge and understanding of natural phenomena. SCIENCE JATHA seeks to bring to the people a fullest awareness of the potential of science and to actively involve them in the movement to link science with the people.

Quasi Crystals - Beyond Conventional Symmetry

Duration : 19:01    Year : 1988    Code No.222

It was thought for a long time that five - fold symmetry is not possible in crystals and that five - fold symmetric figures like pentagons cannot repeat themselves periodically to form a crystal lattice. But recently scientists have found an aluminium manganese alloy that showed five - fold symmetry after rapid cooling. Dr. Roger Penrose of Oxford University speaks about his mathematical theory of tiling through which, perhaps, the structure of these quasi crystals can be understood.

In The Eye Of An Insect

Duration : 14:45    Year : 1988    Code No.228

This programme deals with some amazing structures - the Ommatidia and Corneal nipples - of some insects, seen through the electron microscope. Various Ommatidia and Corneal nipples are compared and related to the habits of these insects.
