Apparently Bill Gates bought some tapes and released them to the public. I've been listening to them all day, and I'm enjoying the hell out of them. In lecture #2, the one on the relationship between mathematics and physics, he talks about how mathematics is the language of physics but that mathematics alone cannot give one a thorough understanding of physics. He starts talking about how mathematicians are restricted and that language (concepts) plus mathematics is what makes physicists so brilliant. I'm paraphrasing him, but that's essentially what he said. Here's my question: where can I get a list of all the key terms in physics? Inertia, gravity, acceleration, velocity, etc. Yeah, I already have those, but I want the rest. Is there either a website or a general book for the public that contains all the important words involved in understanding physics, at least on a non-mathematical level? In other words, I accept that I'm not smart enough to learn the mathematics of theories like general relativity, but I absolutely enjoy meditating on the language of physics. I do it all the time, and I'm just wanting a more organized way (list or book) of doing it.
