Just starting out on this book. Only covered the first chapter. I will write a fuller review once I'm deepr into the book.<br>I have always been of the persuasion that professional mathematicians get a 'handle' , 'hook' on a subject by analogies, once these anaolgies hit there limits then these original thought processes are rightly replaced by the core mathematics.<br>What I like about this book and the sister book on complex analysis is that the author gives us the analogies along with the mathematics and equal weight are placed on both and they both go hand in hand.<br>Having had mathematics thrown at me wrapped up in a muddy ball at University and failing miserably at it. I have since spent a large part of my adult life being an ' amatuer mathematician', taking MY time to comprehend subjects MY way and the two books by the author are the closest I have come to finding someone who thinks like me (or I think like them).<br>Great book. I'm looking forward to continuing on the journey with this book.
