While I read this, I kind of assumed that this was written by a math-enthusiastic 9th grader and it felt wonderful! Write down your new-found math skills, that will make you remember them even better for the future and also trains writing skills! Then I learned that he'd been out of school for quite a few years and is a programmer now. That makes me pretty sad. Is it really such a novel insight to learn about the relationship between exponentiation, roots and logarithms that you need to write a blog post? Isn't this basic school math anymore that everybody doing anything even remotely related to math should know by heart? (Programming definitely counts into that..) How do you even do things like basic finance, interest rates, inflation, without groking this? It makes me worried not just about the future of society in general, but about our industry in particular. I'd feel uncomfortable working at a place where any of my coworkers would feel compelled to write a blog post about the relationship between exponentiation and logarithm that explains that exponentiation is not commutative.
