Explore the dynamics of biological systems in this lecture from a comprehensive summer course. Delve into how physics tools can explain complex living systems' behaviors, covering topics like predator-prey population oscillations, multi-species ecosystem chaos, and microscopic organism swimming. Learn to model and predict phenomena such as species competition, population catastrophes, bacterial motility, and collective behavior in fluidic environments using principles from nonlinear dynamics, statistical physics, and fluid dynamics. Designed for undergraduates with no prior biological knowledge, this pedagogical approach introduces biological physics concepts over eight sessions from May to June 2024. Participate either in-person or online, with potential additional tutorials to supplement the main lectures.
