<p>What can physics tell us about biology? This is the question we start off with in our conversation with Dr. Francesca Serra, a professor in the Physics Department who studies soft matter particularly a phase of matter called liquid crystals. We talk about liquid crystals, topological defects, thermodynamics, and how these physical phenomena can provide insights into biological processes. We also move into a bigger conversation about what we can learn about life from physics and if physics offers a possible answer to the secret of life.
