Topic 1 : Introduction & Some Lessons from Ptolemy
We will start with an introduction to some of the
basic issues in considering the evolution of the Universe
and the essentials of modern cosmology : the big bang theory.
Then we will digress to consider a very different but, at the
time, very successful picture of the Universe, namely Ptolemy's
model in the Almagest, and consider what it can tell us
about how to approach understanding of the Universe.
