The audio book starts out strong in regards to the main title “When Einstein walked with Godel”. I had expected the book to continue on this premise. After the first half the author started wandering into more diverse topics beyond the range of science and more into philosophy as the author clearly states his own ideas. There are some interesting comparisons to science and philosophy such “Flatland” and others. Trying to enhance the quantum states with the real world can be a real challenge. Over all I was pleased with the book. Excursions to the edge of thought though are really out of Jim Holts mind, not Einstein or Godel’s.
