Jonathan White’s Tides will hold a distinct place in literature as the story of tides on our planet, and perhaps beyond, unfolds. His book is not cursory, nor exhausting mathematically or astronomically. The author does impart substantive understanding, linkages to human dimensions, and speaks to the ephemeral nature of our existence. No one who is the least bit intrigued by the subject will have satisfied their interest in tides without reading this book. I believe it will be the classic work on the topic for the long foreseeable future.
