Ryan P. Williams: the Claremont Institute standing athwart history
Today Razib talks to Ryan P. Williams. He is president of The Claremont Institute, a position he has held since 2017. He is also a contributor to The Claremont Review of Books and started The American Mind. Williams earned a B.A. in political science and Economics from Hillsdale College and an M.A. in politics from Claremont Graduate University. He has taught American politics and political philosophy as an adjunct professor at California State University, San Bernardino and Cal Poly Pomona. Razib and Williams first discuss the origins of The Claremont Institute and the influence of Harry Jaffa on the think-tank's founding and current thought. They explore the influence of Jaffa's mentor, political philosopher Leo Strauss, upon his worldview, and the differences that define the "west coast Straussianism" associated with the Institute and "east coast Straussianism." Williams also articulates how the conservative thought of Claremont affiliated scholars and pundits differs from other movements on the right, and in particular, how it is differentiated from both neoconservatism and paleoconservatism. Razib and Williams then go over The American Mind's decision to publish Michael Anton's "flight 93 election" piece, and the connection of many Claremont scholars to the Trump administration and the MAGA movement.

Chad Orzel: the state of physics and academia in 2025
Chad Orzel is a physicist and science writer who has been blogging for nearly twenty-five years. He's the author of four books, Breakfast with Einstein: The Exotic Physics of Everyday Objects, How to Teach Quantum Physics to Your Dog, How to Teach Relativity to Your Dog, Eureka: Discovering Your Inner Scientist and A Brief History of Timekeeping. The last is a mix of cultural and engineering history, archeology and physics, and reflects Orzel's wide interests as reflected in his Substack, Counting Atoms. In this episode of Unsupervised Learning Razib surveys the state of physics communication and science, as well as our broader culture's relationship with academia. Orzel and Razib first discuss the massive success of physicist-turned-YouTuber Sabine Hossenfelder. Emerging from academic physics and associated with Lee Smolin and the Perimeter Institute, Hossenfelder has shifted from skepticism of mainstream theories like string theory to arguing that academic science as a whole must be restructured. Orzel also notes that contrarian or heterodox views in popular areas such as astrophysics and particle physics receive much more attention than applied fields like solid-state physics. Razib and Orzel reflect on how science communication has changed over the past two decades, moving from the text-driven blog era before 2010 to the rise of podcasts and video. They also discuss the many technological applications of physics in the 21st century, particularly in battery technology, an area that is transforming daily life but rarely serves as fodder for glossy popular-press treatments. In the second half of the podcast, Orzel considers how science, and academia more broadly, have navigated the adversarial stance of the Trump administration. Razib asks whether institutional science, shaped in the post–World War II era, may be due for a major transformation, or whether it is even approaching the end of its line. Finally, Orzel addresses whether academics can regain broad public trust in the wake of the extreme politicization of the 2010s.
