I was fascinated by this book from the moment I picked it up at Barnes & Noble. I had heard of a few of the writers Brockman tapped for this volume, but I was unfamiliar with most of the names listed in the table of contents. Moreover, I could not find any rhyme or reason to the authors selected to present their various perspectives on what should, in fact, be on our radar screens when it comes to what we should be distressing about. Although everyone arguably has some connection to science, I found it impossible to identify a common thread characterizing all of the contributors.
Most of the selections run only two to three pages, which made the book particularly easy to digest in a series of short sittings. Over the week it took me to get through all of the vignettes, I probably spent no more than an hour reading the book at any one time. Still, many of the ideas resonated with me on several levels. I found myself thinking about what I had read as I was involved in other activities throughout the day. For example, I spent my entire run one afternoon reflecting on the chapter by Martin Rees, “We are in denial about catastrophic risks.” Rees is an emeritus professor of cosmology and astrophysics at the University of Cambridge.
