How does this explain it all? I mean, how does this explain "why temperature and why is it related to molecular speed?" I am not being sarcastic, I am curious as to where you go with this. One of the problems I find with physics curriculums that are too lacking in math (which I am not inferring you meant) is that essential questions like "why temperature and why molecular speed?" can't even be asked, let alone answered. And I don't think you need calculus to get started in physics. Just plenty of algebra. But can you talk more to how and what goes into "explaining it all?". I use the phrase "it all makes sense now". I think we are talking the same thing, but what is your take on that thing?
