They supplement and compliment my book <em>Important Things We Don't Know: About Nearly Everything</em> and are presented here as an accompaniment to that book. </p><p></p><p><span style=color: rgba(0 0 0 1)>But this volume can stand on its own.</span> </p><p></p><p>For several years I periodically updated <em>Important Things</em>. But I decided to leave the last edition as the last. Nonetheless I keep reading and thinking.
