Happy Pi Day, readers! Don’t forget also to celebrate International Pi Approximation Day, which falls on the 22nd of July. (That’s 22/7, according to the more common method of abbreviating dates.)
Today I started reading the first chapter of my calculus book, which provides a review of functions. I struggled badly to concentrate on today’s reading, for reasons I’m not sure of. Possibly it is just that I slept poorly last night. Better luck in the morning, I hope.
