CHENNAI: Are there underlying algorithms that tell you how society works? How do birds like parrots eat hot chilies when humans cannot handle it? What are the vulnerabilities in drug-resistant bacteria? Which laws of Physics can be used to improve stability while dancing?

It is an annual lecture series, organised by the Institute of Mathematical Sciences (IMSc).
