I wasn't sure I was going to finish this, but it really picked up about 30% of the way in.

It's a relatively light overview of a load of stuff (no prizes for guessing that bit)

You're probably familiar with all of it, but there will be gems and additions to knowledge that are delightful.

A highlight for me was the discussion of time, the age of the universe and how our understanding of that has changed (and is still changing)
