Yesterday, two books arrived in the mail, taking me back to those days of ranked scores. My friend Bernard (who took calculus at the university that year from his professor father) has written calculus textbooks and sent our family the latest edition. He is also the author of climbing guides for Rocky Mountain Natuonal Park and now this latest for St. Vrain Canyons. He is an engaging writer and excellent at description. So, this afternoon I began reading Calculus for Scientists and Engineers: Early Transcendentals. Armed with a composition book, I am motivated to restart my own calculus journey (halted 28 years ago when I did not need it for graduation). Interspersed between pages are notes from Bernard about things we should know, making me smile as much as the letters he and I exchanged every summer while their family lived in Estes Park during middle school.
I love the definition in the first page.
"Calculus is the study of functions, and because we use functions to describe the world around us, calculus is a universal language for human inquiry."
