From Ancient Egypt to Leibniz... Brand‑new interview out with Robert Spekkens of the Perimeter Institute, one of the sharpest minds working on quantum foundations. In 2004, he constructed a classical toy theory where your maximum knowledge is always incomplete—and out popped the no-cloning theorem, teleportation, and interference effects Feynman deemed impossible to reproduce classically. Spekkens compares our situation to Egyptian hieroglyphs before Champollion: a category mistake where we treat quantum states as descriptions of reality when they actually describe knowledge of reality. If you’re interested in the topics above, you’ll love this podcast.
