Podcast appearance: listen to me talk about The Random Universe (the book, and the Universe itself) on Sean Carroll’s Mindscape. We cover epistemology, probability, quantum mechanics, cosmology and more. Sean and I were cosmology grad students at the same time, and it was a pleasure and an honour to spend time with him online.

Surprised that Taylor needs to promote her latest with an A4 poster at the Imperial College elevators (lifts).
