Emily Weiss from Northwestern University joins the podcast for a wide ranging discussion. We start by asking a deep question: "What is good science?" The answer takes us from the discovery of Neptune to the marriage of basic and applied science that made Bell Labs so great. We then discuss her lab's interest in the interactions between light and quantum dots, tiny crystalline particles with diameters less than about 5 nm. We also find time for Emily to share her vision of a future where biology can be investigated not only on extremely short length scales, but also on extremely short time scales. Stick around for a brief after show if you've ever wondered about making poached eggs. This episode has it all. (Recorded on April 25, 2018. Edited by Andrew Cannon)
