These books show more than anything else why Feynman is so revered among physicists as a teacher. An introductory course in physics, simple yet demanding, and shot through with Feynman's unique approach and personality.
That's correct. Having said that, they're a fantastic refresher for someone who has studied all of this at the high school / university level and wants to get a crash course. Feynmann loved his technical crash courses and these lectures show that he has a mastery of distilling out all of the details and leaving none of the chaff.
this is obviously a great news for Physics lovers like myself. I have been always intrigued and fascinated by Physics and unfortunately did not able to pursue it as my career but having free access to Feynman's lectures would definitely ignite passion in me and lot of others who are interested in subject.
