I like it when author use pictorial logic instead of mathematical formulas that sometimes complicate instead of helping readers to understand, Michael Young did an excellent job to convey by using diagrams that connect with each other; more intuitive way to learn for those less inclined to numerical formulas.  Still, the logic of the math remains robust and intact.
