Calculus Made Easy is a book on calculus originally published in 1910 by Silvanus P. Thompson, considered a classic and elegant introduction to the subject.From Wikipedia
I read "Calculus Made Easy" by Silvanus P. Thompson and it's still to this day my inspiration for explaining complex technical topics to lay people. It's a fantastic book, and even if you know math you must read it if you want to understand how to teach complexity to others. (source)
Thompson creates a warm, inviting environment where students will learn and grasp the true essence of calculus without any added fluff or overt technicality. (source)-- MathBlog
Most college calculus texts weigh a ton; this one does not — it just gets to the point. This is how I learned calculus: my uncle gave me a copy. (source)
