Martin Schwartz, a professor at Yale, is known for his work on integrins and his influential essay “The importance of stupidity in scientific research”. He emphasizes that while learning science makes you feel smart, true scientific discovery often involves feeling stupid, because it means venturing into the unknown. We discuss how the ego can obstruct creativity, and how resilience, self-discovery, and the cultivation of "passionate indifference" – being deeply engaged but unattached to outcomes – are key to sustaining a productive and fulfilling life in science.
