Well, I didn't actually mean it like that.:) I meant it in the epiphany sense.

I am curious though, I didn't quite follow what your question was (excite things?) and what the current research might be? Can you elaborate? I am trying to leap from the beginning of the story, a glass of wine (mostly water), ice (frozen water), the notion of heat capacity and the delta between your desired wine temp and the room temp..... to ..... current research.:)

He was amazed at the small amount of ice it took to satisfy me and I explained the nature of those coefficients to go from one state to another but only in the most primitive form of why that might be. Sunday I was with a friend who is working on her PhD in physical chemistry at Caltech who I took aside to ask for a layman's explanation of why so much energy is required to excite things because I seemed to have forgotten that aspect. She said, "I'll give you the professional answer, 'Nobody knows,'" followed by laughing and explaining some of the areas of current research underway. But the bottom line was still the same.

>> 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?
