Explore the fascinating world of pattern formation in biology through this comprehensive lecture by Vijaykumar Krishnamurthy from the International Centre for Theoretical Sciences. Delve into hydrodynamic theories, Einstein fluctuation formula, and conservation laws as they apply to biological systems. Examine the cytoskeleton as a force generator and learn about the actomyosin cortex of cells. Discover how hydrodynamics principles can be applied to active gels and the actomyosin cortex. Investigate pattern formation in active fluids, including stationary patterns in the cortex and active pulsatory patterns. Gain insights into force balance and participate in a Q&A session to deepen your understanding of this complex topic.
