Are there any people in recent history who never went to university to learn physics and just taught themselves using the internet and books? Is it really possible to get a solid understanding of physics just from reading and practice? I guess it would be a bit hard to test certain experiements due to lack of equipment but nevertheless is it doable? I live 10mins from a university and thought about sitting in on their physics lectures as the lecture halls have no form of security. I could get copies of the lecture hand outs ect. Only thing is I wouldn't be able to get my work marked but just wanted a professional opinion.
