Einstein understood something that most educational rhetoric glosses over: that joy and knowledge aren't pleasant accompaniments to learning but rather its very engines. Notice he doesn't praise teachers for delivering information efficiently or even for clarity—but for *awakening* something already present in the student, which is a fundamentally different enterprise. When a good math teacher shows a struggling teenager that an elegant proof is genuinely beautiful, something shifts; suddenly the student wants to understand, not because they fear a grade but because they've felt the pleasure of thinking. That's the difference between a teacher who transfers facts and one who makes a mind come alive.
