I first read these as an undergraduate physics major. They are fascinating if you already understand the physics, because his approach is always unconventional and a little brain-bending. For an introductory text for those not familiar with the physics, they are often very confusing. I would not recommend them to someone trying to learn physics. Go learn physics elsewhere, but then absolutely come back to Feynman and look at the things you have already learned in a very different light.
