Update:<br><br>The previous review below mostly applies to Kindle App on Android (phone or tablet).<br><br>Reading on Kindle on a Windows computer (I am using the Cloud reader) is much easier and the equations can be read.<br><br>So if you are planning to use Kindle on a computer to read or the print version, the book is fine.<br><br>Well-written, has expected content.<br><br>Previous review (applies to Kindle on Android):<br><br>When somebody buys a book that costs as much as this one, they have a right to expect a product that has high quality in every sense.<br><br>As another reviewer has pointed out, equations and other mathematical notation are in very small, virtually unreadable font size.<br><br>Zooming leads to a dark blurry image, pictures that do little to aid readability.<br><br>The content of this book is what is should be - it is a shame that the Kindle version is so hard to read.<br><br>All equations and pictures need to be re-formatted and that updated version should be offered free to current owners of the Kindle book as an update. As it stands, buyer beware!!
