- johncolanduoni 11y ago> C-algebras are an esoteric subject—“the most abstract nonsense that exists in mathematics,” in Casazza’s words. “Nobody outside the area knows much about it.” Wait what? C algebras are very familiar to many doing quantum information, even those on the more experimental side. I don't think they even make the top 10 for "most abstract nonsense that exists in mathematics".
