So I read another textbook, this one was about high school chemistry. I gave it a pretty light read because I'm not a big chemistry fan and didn't want to do a bunch of stoichiometry exercises. It was interesting enough I guess, but one thing that struck me was that there was an entire chapter (the whole book is only 12 chapters) on Moles. For those who don't know, a mole is a unit in chemistry, it's like how a dozen means 12 things, a mole means 6.022*10^23 things. Doesn't seem like the most complicated thing in the world. In fact, this really comes as a shock if you're also learning physics like I am, where a textbook will introduce some random ass unit from out of nowhere (Teslas, Farads, Pascals) and explain it in literally one sentence. Anyway, the elitist in me was all shocked that it takes so long to explain such a simple concept to 11th graders. Then my prof said something enlightening, along the lines of "you'd probably have a hard time explaining to someone why 2+2=4, because you just get it." I realized that I have absolutely no concept of how difficult certain things are in school, because I've been surrounded by concepts for so long that they seem obvious to me. This book helped me realize that I'm missing that perspective and that I need to be more respectful of people who don't get the same things as me.
