Meaning of: "Make everything as simple as possible, but not simpler." I'm new to physics, but have been reading biographies and watching documentaries on physics for the past year (before I take it next year in school). I've heard that Einstein said, "Make everything as simple as possible, but not simpler." I'm wondering what he meant by that? It was confusing, because I thought physics is not simple at all!!! Do you guys know what he was referring to or what he even meant at all? I've seen this quote actually from a lot of websites too. Thanks a lot for your thoughts. I hope to learn more from this site as well.
