I used a vacation day from work today to attend my Wife's chemistry lecture over at MCTC as a guest. It was pretty cool. The instructor discussed buffer solutions, aqueous solutions composed of a weak acid and its conjugate base that is resistant to changes in pH when relatively small amounts of a stronger acid or base are introduced to the mixture. She also showed the class how to calculate a mixture's rating on the pH scale based on the molarity of dissolved hydronium ions (H3O+) contained therein. I have some catching up to do in reviewing the textbook for the class to bridge this concept to those I have already read about, but I think I understood the basics. I was able to surmise the appropriate means of solving most of the problems on the worksheet that was handed out based on what I've read from the textbook, the day's lecture and what I've retained from taking Pre-Calculus last Spring (I'm extra glad I took pre-calc now); that was pretty cool. Right now, I am super excited for Principles of Chemistry [I] this Fall.
Before I attended the lecture this morning I got up early enough to make some breakfast (I lied it in spite of the portion I burned) and took advantage of the available time to visit the bench dedicated to Abdu’l-Bahá in Loring Park again where I practiced some solitary prayer and meditation. After the lecture I picked up a copy of Scott Pilgrim's Finest Hour which Kristin and I successively read with enough enthusiasm that we were both finished within a couple of hours. I felt it was pretty intense as a concluding volume for the six-book series, and very fast paced. Good closure, and I'm still looking forward to the movie.
I am very proudly a geek/nerd.
