#TCAFG (The Coarse And Fine Grained) --- SynTalk
How do you like your Matcha? Why do fine and coarse materials behave very differently? Is surface texture usually a sign of sub-structures? How does rock become clay? Is dry clay enough to understand wet clay? Could tea be smoked? Is it simple to keep every spoonful of your morning cereal mix similar? Do pure dry solids ‘flow’ in layers and parts? Is soil a definitive sign of life? How are dust and coarse-leaf teas different? Does mechanical agitation organize matter differently from Brownian motion? How/why does swelling happen? Can mechanical grinding lead to fine structural (chemistry) changes? Does fineness evolve life ‘around’ it by offering its ample ‘surface area’? What is a tea bag? Would you be able to easily tell (moving) life & non-life apart under a microscope? Could microbes induce life into fine matter? How does refinement happen? Why do water drops jump to contact when brought close together? What flocks? What ‘flocs’? What lies ahead? Would we deploy small active rotors & ‘swimmers’ to change materials? &, will we one day understand the fundamental physics of all open pattern-forming systems? SynTalk thinks about these & more questions using concepts from active matter physics (Prof. Sriram Ramaswamy, IISc, Bangalore), geotechnical engineering (Prof. D. N. Singh, IIT Bombay, Mumbai), & chemical engineering (Prof. Gurmeet Singh, Trans-Disciplinary University, Bangalore). Listen in...
