This was my favorite book on interpretations of QM I have read. I really enjoyed it. I really appreciated that unlike some books on the topic which are overwhelmingly theoretical, this book grounds its math and philosophy in real, tangible experiments. It returns to experiments again and again, reminding us why physicists have been forced by the results of these experiments to question some of our most basic ideas about the world… realism, locality, even the idea that the world has a single past, present and future.
