How precise is life? In this visually compelling and thought-provoking talk, "accidental biologist" Mukund Thattai sets out to answer this question. He explores the theoretical concept of exactness through concrete examples such as a golf ball, a spacecraft, and one's own palms. Concluding with a vivid analogy of a street painter, Dr. Thattai leaves his audience with a sense of wonder. This presentation was featured at an INK Salon, "Exploring Excellence", at the National Centre for Biological Sciences in December 2015.
