Sean Carroll is a US theoretical physicist (Johns Hopkins University, formerly Caltech) and one of the most prolific science communicators working today. He is the host of the long-running Mindscape podcast and the author of Something Deeply Hidden, The Big Picture, and a multi-volume textbook series on modern physics.
His CourseFlix listing carries The Many Hidden Worlds of Quantum Mechanics — a structured walkthrough of the modern interpretations of quantum mechanics (particularly the Many-Worlds interpretation Sean is associated with) at a level aimed at intelligent non-specialists.
Material is paid and aimed at general adult learners interested in physics. The course sits in the broader Math & Statistics catalog on CourseFlix.
