iTHEMS Colloquium by Dr. Hong-Yan Shih on April 22, 2022

On April 22 (Fri), we had the first iTHEMS colloquium of FY2022 by inviting Hong-Yan Shih from Academia Sinica, Taiwan. After reviewing the turbulent phenomena in various area of science, she discussed how the turbulence occurs by increasing the flow velocity and how one can develop an effective theory to describe the critical region of laminar-turbulent transition. Then she discussed a remarkable mathematical relation between the effective theory with the predator-prey dynamics in ecology and showed a characteristic super exponential scaling law. The topic was an ideal subject for the interdisciplinary talk, and there were many questions from the researchers with different scientific backgrounds.
