Lawrence Krauss is a lucid writer on science topics but I see few people that'd benefit from this book. The overview of science is a summary rather than an introduction except on some topics where the author seems to inconsistently go into depth. The difference between BOOMERANG and WMAP are neat but not necessary and seem to be largely filler in this otherwise thin book. The author talks about "symmetries" but doesn't really describe the much more in-depth types of symmetry that science provides vs. say left-right (bilateral) symmetry. There was little discussion on why some things are conserved and others are not and this is both handy in explaining a lot of things and quite beautiful.
This is short for one of my reviews as this book is like most of Krauss's, very meh. Watch the YouTube video of his presentation on the universe from nothing if it saves you the cost of this book.
