I think this is still fair. I mean when you study Physics you learn to use apparently confusing tools - theoretical or experimental - with confidence. Sometimes in areas that only few people find interesting/appealing, like for instance complex problems in classical mechanics or thermodynamics. Only 1% of the studies is about crazy, absolutely counter-intuitive stuff that sounds like Sci-Fi. But isn't that what differentiates the amateur from the Pro? ;) I mean if people want to do actual Research Physics, they must either go to a University (offline or online) or be mega disciplined. In the latter case they need a few more books though/adjust them also to personal taste.
