Carl Bender is an applied mathematician and mathematical physicist holding positions at Washington University in St. Louis, the University of Heidelberg, Imperial College, London. He was also one of my own favorite lecturers. He taught me about perturbation theory and asymptotic series which are powerful mathematical tools for solving difficult problems in physics. I invited Carl on to the podcast to discuss complex numbers, and their application in physics. At a conceptual level Carl talks about the link between mathematics and reality, the history of complex numbers and what they are good for, his research into weird new quantum systems known as PT-symmetric quantum systems, his interactions with Richard Feynman, and the role that beauty plays in Mathematical discovery.

Boysober
Have you ever wondered what life might be like if you stopped worrying about being wanted, and focused on understanding what you actually want? That was the question Hope Woodard asked herself after a string of situationships inspired her to take a break from sex and dating. She went "boysober," a personal concept that sparked a global movement among women looking to prioritize themselves over men.
