Episode notes
Peter Woit, senior lecturer at Columbia and author of *Not Even Wrong*, critiques the failures of grand unified and string theories and argues that they have stalled the search for a unified physical law. He introduces a new four‑dimensional geometric approach based on spinors and Wick rotation as a possible path forward.
