Not a great book for me, but might be useful to others. It purports itself to be the kind of reference book you keep next to your dictionary or cookbook - not sure anyone would really do that! I either already knew about the subjects - what is pH, how to calculate simple and compound interest, how vision is measured, what do the numbers mean in your blood pressure reading - or I didn't really care (what biorhythm cycle am I in, fabric for your pattern, gambling probabilities).
