This book does a few things really well.

It uses the double-slit-experiment (and a few related experiments) to critically review the most important interpretations of QM. This includes pointing out the problems with each theory. This is actually rather tricky to do in a book for non-scientists, and this is one of the only books that I have read that does this well. This is refreshingly straightforward without the bombastic exaggeration, mysticism, or fringe theories common in such books.

It covers the double slit experiment and a few others without making numerous mistakes (which is rare for this sub-genre) while keeping the descriptions remarkably clear. This must have been edited very carefully.

It would have helped to have a pdf to provide diagrams of the experiments and complex cases. Instead you can google the author to find good diagrams of each experiment (particularly the Elitzur–Vaidman bomb tester).

Usually Bohmian Mechanics gets faint praise and the worst criticisms, but here its importance was highlighted and is was criticized less than it should have been. Although Bohmian Mechanics is very *important*, its focus on Position is a critical issue…not that position is problematic, but Bohmian Mechanics could be reformulated to focus on Momentum (instead of position). Having complementary theories like this leads one to doubts about which (or either) can be real.

Another nit is that the author seems to go out of his way to avoid discussing Action (which leaves a layman reader thinking energy is quantized). He briefly discusses Feynman’s multipath method without mentioning Action. I understand the desire to avoid the topic, but books that ignore it leave the reader with a critical misunderstanding.

The narration was completely excellent.
