  Cosmology is the dot com of the sciences. Boom or bust. It is about nothing
less than the origin and evolution of the Universe, the all of everything. It
is the boldest of enterprises and not for the fainthearted. Cosmologists are
the flyboys of astrophysics, and they often live up to all that image conjures
up. It is hardly surprising then that words written about cosmology are rarely
balanced. They verve to one extreme or the other. .... Once or twice, I have
probably been guilty of irrational exuberance when it comes to cosmology.
