+"I think, however, that there isn't any solution to this problem of education
+other than to realize that the best teaching can be done only when there is
+a direct individual relationship between a student and a good teacher---a
+situation in which the student discusses the ideas, thinks about the things,
+and talks about the things. It's impossible to learn very much by simply
+sitting in a lecture, or even by simply doing problems that are assigned."
