Concise, elegantly simple, and precisely measured for student consumption over one semester (16-17 weeks). Masterfully hidden from view are the edits, re-edits, discussions, Tex/Latex tutorials, file conversions, hand-written notes, lecture preps, student questions and a hundred other details that end in an 814 page treatise for humans to enjoy via that "other thing" they did at UIUC. Well done Jeff Erickson, et.al.
