From measurements on both large and small scales, to statistics, to particle physics and cosmology, with a couple of detours into artistic creativity, Dr. Randall has been effective at communicating the enthusiasm toward her subject into a text that is accessible to even those who don't have a strong base of knowledge of that subject matter.
As CERN's LHC produces new data that researchers are able to parse and add information to our ever expanding knowledge of the universe, I expect that we'll be seeing an enhanced version of this, or even better a sequel.
