Supplementary material from "Roddam Narasimha. 20 July 1933 - 14 December 2020 "

Roddam Narasimha's scientific research in fluid dynamics encompassed turbulent flows---including the transition from the laminar state to turbulence and vice versa---kinetic theory of gases and structure of shock waves, nonlinear dynamics, aspects of tropical meteorology motivated by monsoons, as well as problems related to aeronautical engineering. Besides his life-long engagement in teaching and advanced research, he held leadership positions in learned societies and national institutions, articulated original perspectives on Indic philosophy as well as history of science, and provided diligent advice to the highest levels of government. In particular, he was deeply immersed in India's technology development---specifically the light combat aircraft and the light transport aircraft---and worked on the implications of commercial supersonic flights over Indian airspace, stochastic theory of airworthiness of aircraft, etc. Above all, Roddam was known for the incisive quality, depth and perspective of his work, the dignity of personal interactions with people at all levels, and his energizing influence on younger colleagues.
