Emmy Noether's Wonderful Theorem by Dwight E. Neuenschwander
Emmy Noether's Wonderful Theorem by Dwight E. Neuenschwander

This is a wonderful book that explains both the physics and the mathematics very well. Other reviewers have already written about the specifics that make this a good book.

The reason why I give only four stars is that the Kindle edition is pretty awful. If you care about beautiful typesetting of mathematics you should buy the paper version of this book, because all the formulas are set as low-resolution images (as seen on retina display). This is really distracting, and frankly unacceptable. The problem of typesetting mathematics on screen has already been solved (e.g., using MathML), and I am really disappointed that Kindle does not seem to support this. In addition, the regular… Read more
Kyoto & Nara The Soul of Japan by Philip Sandoz
3.0 out of 5 stars low-quality scans, 24 Jun 2013
I bought this ebook prior to my trip to Nara and Kyoto, and it was a bit of a disappointment as a guide to the cities. The text is short and rather superficial, but that is not entirely unexpected of a photo book.

The photos in this book are of reasonable quality (although some are a bit lifeless due to overcast skies), but in the transition from print to ebook rather low-quality scans are used. The pictures look grainy on my retina iPad, and the colours are not deep enough. Ultimately, I regret my decision to buy this.
Quantum detection and estimation theory by Carl W. Helstrom
This is the classic early work by Helstrom on quantum measurement theory that has been out of print for years and has been available only at a highly inflated price (I have seen it online for in excess of $380). Most of the content of this book has been incorporated in more modern texts on advanced quantum (information) theory, but there is definitely value in going back to the source, if only for giving proper attribution to this pioneer of the field.

However, why are we expected to hand over 70 for a paperback that is a straight facsimile of the original? The publisher did not even bother to invite a big name to write a preface. When printing on demand is a cost-effective… Read more
