I honestly admire the author for being able to waffle 400 pages of uncritical content. This book tries to approach so many topics in such a vague way that it could well have been 100 different Buzzfeed listicles. The author is a theoretical physicist, so you just know she thinks she knows everything. In one single unnecessarily long book, she talks about the philosophy of religion and science, the nature of spiritual belief and its opposition (or not) to scientific belief (all the while asserting that only science provides the OnE tRuE oBjEcTiVe KnOwLeDgE), the nature of the mind and of consciousness, climate change, macroeconomics, government policy, the history of CERN and the LHC, the fundaments of particle physics, string theory, dark matter and the cosmos. At one point, the author blatantly states that “we know dark matter exists because (…)”, girl do we? Do we, now? If you’re so certain, go get that Nobel Prize you didn’t win for string theory! Also, she really tries to sell string theory as the answer to God, but girl come on we all know it’s a failed ~hypothesis~ (not even a theory). If all of this doesn’t put you off, there is an excessive amount of unnecessary anecdotes which seem to serve only for name-dropping famous people the author knows; all throughout the book she repeats ideas three times in the same paragraph; and, while sometimes she takes time to explain in detail what a concept is (say, the equivalence between high energies and short lengths), sometimes she just drops a completely new thing out of the blue, like beta decay. The author just mentions it in a sentence without explaining it one bit. Who is this book even for? Physics undergraduates? Philosophy students? The general public? I argue it’s for no one but the author’s ego.
