No, you explained that really well!! Everything is a lot less fuzzy now! Thank you :) I think with science, the first time I read it, it makes sense to me, but I had such a bad habit of filing scientific facts into the "things you learn in school but don't really need to remember for real life" category of my brain that now, even when I actually care about learning new information, it still takes multiple explanations, and sometimes one really good one like yours, before it really start to sink in for me.
