Title: Kindle edition has problems
Review: A brilliant book, but unfortunately the Kindle edition has problems. For example, the Greek letter pi, referenced often in the book, always shows up as a blank square. This makes it difficult to read. I'd expect this kind of textual error with an amateur OCR text, but not in a $10 version.
