of “precision cosmology” has led to the currently accepted paradigm of a
universe that began in a dense, hot, nearly uniform state, and subsequently
expanded and cooled through dynamics controlled by dark matter and dark
energy.  Within this framework, however,
there are still many unanswered questions. 
One question is the process through which galaxies, stars, planets, and
ultimately life emerged from the primordial soup.  Theoretical physicists are building models of
the emergence of structure and, aided by today’s powerful computers, are making
remarkably detailed predictions. 
Experimental physicists are building large telescopes that are sensitive
enough to detect signals from objects so far away that we are seeing them as
they were thirteen billion years ago, when the first stars and most chemical
elements were just starting to form. 
This lecture will describe some of the first confrontations between the
theories and the measurements, with a focus on the large radio telescopes that
detect distant hydrogen gas to trace the formation of structure.</font></span></p>
