There's quite a bit in there that could be "more" correct than what we were taught in school, but keep in mind, there may be other things that are way off from the true reality.  The best take I get from the whole thing is to keep an open mind and think for yourself.  Just because someone says something is so, doesn't mean it is.  Knowledge is clearly an evolutionary process.  You take bits and pieces where you can get them and try to put a puzzle together that you can work with.  Hopefully by the end (of your life), you have something that makes sense and plays well between your perception and the environment around you.  There is no free lunch and what I mean by that is sure, someday you may make a free energy device, but the path it took to get there, the understanding you had to assemble, was by no means free; it takes a whole lot of work.  The hardest part is keeping straight in your head what always works, what sometimes works and what never works.  Those are constantly moving targets and you need to stay on top of them to move ahead.
