Our everyday lives are lined by collective behaviour of all kinds of things, particles, and beings. Have you wondered if it is possible to formulate physical ideas that can lead us to understanding these fascinating behaviours that seem to appear out of sheer randomness — imagine the flocking of birds, movements of schools of fish, aggregation of bacteria, self-arrangement of bio-polymers— the highly non-trivial out of equilibrium systems that are driven by supply of energy, essentially the living or non-living systems? The study of such systems is now popularly termed as active matter, and our guest for this episode, Prof. Sriram Ramaswamy, is known to have made seminal contributions to the field amounting to giving birth to and shaping the field of active matter, and laying the foundations of the hydrodynamical approach for studying these systems.
Prof. Ramaswamy, Fellow of the Royal Society, is currently a Professor at the Centre for Condensed Matter Physics at IISc Bangalore. His research addresses the quintessential questions of the physical world wherein the quantum mechanical descriptions do not enter the scene and the classical pictures rule over the complexities, using the powerful principles of the symmetry and conservation laws, under the broad regimes of condensed matter physics.
Listen in to our discussion with Prof. Ramaswamy, where we delved headlong into discovering more about the vast horizons and excitements in the field of active matter— Prof. Ramaswamy makes a call to all the bright young minds, to take a curious look at what wonderful ideas are in store to make sense of the physical world, and the apparent randomness in the absurdity of life.
