Literature Growth and Author Productivity Patterns in Indian Physics

Abstract Studies the growth of Indian and World physics literature from 1900-50. Explores the applicability of selected technology diffusion models to the growth of literature in Indian and World physics. Focuses on the applicability and validity of two forms of Lotka's Law and negative binomial distribution model to the cumulative author productivity data on Indian physics. Looks at the linkages between inequality/concentration measures and development of Indian physics as a discipline. Explores the relevance and applicability of two well known generalisations, Price Square Root Law and 80/20 Rule to the cumulative author productivity data on Indian physics. Studies the increase in the number of practitioners, at different productivity levels, and the emergence of core authors in Indian physics.
