Title: not sure the book has the right conclusions
Review: the author claims that there's no device which measures an imaginary number; well, for EE's, an imaginary number (phasor) can be measured with an oscilloscope since oscilloscopes can measure amplitude and phase; this representation can then be converted to an imaginary number. the author also claims that you can't have -5 apples in a box and this seems sinister since -5, for example, would mean that there's an IOU in the box after the vender had 5 apples and bartered 10 apples for something he wanted. in this case, when the vender got a dozen more apples, 5 of them would be owed. perhaps I should read more than amazon's sample pages but the ones I read didn't seem that complete.
