Brian does a great job of consolidating all the historical discoveries germane to this highly evocative insight of a very possible explanation of the full accounting of what we've learned about the universe to date. It's still one of mankind's greatest mysteries as to why elegant mathematical descriptions of nature often prove to be so accurate in the end - perhaps we're learning that our collective, scientific (apolitical) spirit will ultimately allow us to glimpse at the beautiful "mind of God" (for mathematics is the universally accepted language of all men). Truly a mind expanding book!
