Science Video from Vigyan Prasar

Coverage of science in Indian mass media, especially television, has been very poor. One reason, often heard in media circles, is the absence of a mechanism to cover stories of latest R&D developments from the science and technology institutions in the country. To bridge the gap between Mass media and R&D institutions, Vigyan Prasar has recently launched a science video feature on experimental basis.

 Six feature stories have been produced; three features on National Bureau of Plant Genetic resources and three on latest developments from the National Physical Laboratory, New Delhi. The feature stories cover the profile of the largest gene bank in the world the NBPGR, various Ex-situ techniques to conserve seeds and a report on the plant quarantine division.

 The stories from NPL cover the Teleclock service on transmit Time Data digitally through a telephone line, the SODAR Sound Detection and Ranging technique for air pollution management and the piezoelectric Accelerometer PL-810 to measure vibrations. R&D organizations may write to us for covering interesting Research and Development works happening in their laboratories. 

National Repository of Science & Technology Videos

Vigyan Prasars initiative to set-up a National Repository of Science & Technology (S&T) videos has received excellent response from almost each of the 250 research institutes and organisations contacted for this purpose. Encouraged by this, Vigyan Prasar is moving ahead to work out all the necessary logistics for the repository. Meanwhile, the VHS(PAL) copies of the S&T videos produced by various organisations have started pouring in. Thus the stage is set to bring together, at one place, the entire range of videos on science and technology produced in the country. In this manner the repository will not only be documenting the contemporary history of Indian science, it will also act as a nodal centre systematically catalogue, preserve, store and retrieve the science videos. By sharing information on the available videos, the repository could help to avoid duplications of efforts and facilities exchange of footage etc. amongst the producers of such videos. To bridge the gap between the viewers and the videos, Vigyan Prasar would pick and choose videos available with the repository and consider screening them by organising travelling video festivals in different parts of country. 

Following are the videos contributed by various research organisations to the National Repository of S&T Videos.

Radio Programmes:

Radio as a means of science popularization has always played a vital role in India due to its all pervading reach and affordability of the masses. Vigyan Prasar (VP) has always been striving to utilize this medium in its efforts to take science to the people. As a result three very successful serials were jointly produced and broadcast since 1997; viz Paryavaran Calling with AIR Bhopal, Bipanna Basudha  with AIR Guwahati, and Chhoo Mantar with AIR Delhi. All Indian Radio, Dibrugarh (AIRD) took keen interest to collaborate with Vigyan Prasar and produce a 26-part science serial Prithivi Aur Antariksha (the Earth and the Space). 

Paryavaran Calling:

The idea was to inculcate scientific attitude and awareness about all aspects of environment among the masses. The programme was broadcast from January 1998 to December 1998. 


A 52 episode radio serial CHHOO-MANTAR, jointly produced by Vigyan Prasar and AIR, Delhi. (The programme started on October 3, 1998 and was broadcast every Saturday between 8.00 and 8.30 p.m.) The serial was an interactive programme dealing with the science behind so called miracles. 

Bipanna Basudha( the endangered earth): 

A radio serial Bipanna Basudha (the endangered earth) was on air jointly by Vigyan Prasar and AIR, Guwahati. This 13-episode Assamese serial dealt with science, technology, environment and ecology. Each episode  started with a dramatised version of the theme followed by quizess, experts comments, interesting news clips, etc. for 10 minutes. Best of the Assamese science writers and thematic experts of Assam were involved in this AIR-VP joint project. 

Prithivi Aur Antariksha (the Earth and the Space):

Another radio serial will be  broadcast from AIR, Dibrugarh from March 6,2001 in Assamese. Recently a workshop to plan for this serial and identify the topics, experts and to finalize operational aspects, was organised by VP at Dibrugarh. About 30 experts from academic institutions, research laboratories and science popularizing agencies participated in this workshop jointly organised by AIRD and VP. Dr. Devdas Kakati, Vice-Chancellor of the University, inaugurated the workshop on 24 January 2001 in the presence of a host of eminent personalities of Assam. Dr. Kakati appealed to the scientific community to address to the needs of the society.
