This is the most abstract episode of the series, and also the one where some of the most surprised experts have spoken on the record. Farah and Augustin start from symmetry and infinite-dimensional matrices and work up to problems that a generation of specialists expected to outlive them. We take each claim in its tier, follow the set-theory argument about Naimark's problem, and ask what it means when a field's grand open questions all appear answered in a single afternoon.
