This book breaks ground even now in the 21st Century! There's not a day that goes by - and I mean this literally - that I do not use this book to break ground - and I mean that figuratively. Wait - no, I mean that literally, too, come to think about it, if one considers the as-yet-untilled fertile loam of consciousness the ground through which this slender tome "turns the soil..." When seedling theory raises a tentative monocotyledon into the light of possibility, it quickly wellsprings into that cornucopia however you spell it of brilliant whatchamacallit - information theory or simply the plain old everyday garden variety GENIUS that we have come to expect of Peter D. Johnson, boy inventor. More, Professor Johnson, MORE!!!
