E. C. G. Sudarshan (1931–2018)

On 13 May 2018 the world lost a physicist of deep insight and vision, one of those few who glimpse and formulate a new law of nature. Ennackal Chandy George Sudarshan, born 16 September 1931, was a pioneer of several uncharted territories in physics. Some of them were very timely in the 1950s and 1960s and some others were far ahead of their time, and are beginning to be appreciated only now. One work that became sensational and enchants the common man and had made it to the New York Times is the theory of tachyons, particles faster than the speed of light. The one that is thriving in the emerging mathematics of quantum information is the Stochastic Dynamics of quantum systems.
