Science Quotes by Moshé Flato (1 quote)
One evening at a Joint Summer Research Congerence in the early 1990s Nicholai Reshetikhin and I [David Yetter] button-holed Flato, and explained at length Shums coherence theorem and the role of categories in quantum knot invariants. Flato was persistently dismissive of categories as a mere language. I retired for the evening, leaving Reshetikhin and Flato to the discussion. At the next mornings session, Flato tapped me on the shoulder, and, giving a thumbs-up sign, whispered, Hey! Viva les categories! These new ones, the braided monoidal ones.
