I keep hoping that I’ll have time to learn where science has gone since I last had a chance to study it. And to relearn some of the math I’ve forgotten over the years. At the very least, this will come in handy as my boys continue to take harder courses in school and high school. Sure wish I’d had access to these kinds of tools when I was in school.
