I really liked First Stringers since it is the first book of the Sci-Fi
genre that I read which incorporates the String Theory. However, to
understand what's going on and how the main characters do what they do
no knowledge whatsoever of this theory is required.
In the end two things in this book stand out for me. All of the
main characters are special. Special in this case stands for the best
and the worst meaning of the word. They all have a "superpower" but were
all born with handicaps.
It made me think about how (in-)appropriate language at some times is.
The second point is the criticism Weinberg has on so called "patriots"
of the United States. Always watch out for people who blur the lines
between patriotism and nationalism, especially when the odd portion
of religious (here: Christian) fanatism is added .
On a final note having read several of Weinberg's non-fiction books it is
interesting to see how he let's people and groups of people develop
dynamics in the same way as describe there.
