These essays are on topics reflecting the intersection of science and humankind. They concern time, consciousness,beauty, probability, and understanding. They supplement and compliment my book Important Things We Don't Know: About Nearly Everything and are presented here as an accompaniment to that book.
But, this volume can stand on its own.
For several years, I periodically updated Important Things. But, I decided to leave the last edition as the last. Nonetheless, I keep reading and thinking. So, I have been writing short essays on scientific subjects and including them in my Wanderings books. There are now enough that I thought it worth making them (updated and revised-in some cases, very substantially), along with some new ones, separately available as an addendum to the original book.
This is the second edition, revised and updated.
