This book was extremely useful for me as an undergrad - the way it explains things really gels with me.  It's still a very useful reference now.<br><br>It's a shame though that the typesetting for the Kindle edition is a shoddy bodge job.  Mathematical equations (which are self-evidently vital content in this book!) have just been imported as images.  They have a fuzzy grey background and don't scale properly when you change the font size.  Quite annoying and distracting!
