Explore the captivating realm of fluid dynamics in this lecture from the summer course series "The Fascinating World of Flows." Delve into the fundamental concepts of describing flows, their instability mechanisms, and the transition to turbulence. Connect these theoretical principles to everyday phenomena, such as river patterns around obstacles, cloud formation, and the necessity of stirring to mix substances. Gain insights into how living organisms interact with and influence fluid flows. Learn from expert instructors Prof. Rama Govindarajan and Prof. Samriddhi Sankar Ray of ICTS-TIFR as they guide you through this comprehensive exploration of fluid mechanics and its applications in the natural world.
