The End of Light: Searching for Natural Darkness in an Age of Artifical Light by Paul Bogard has taken me to Paris as an observer of how light has forced the redefinition of night. I did not walk the streets in the dark, out of fear, I suppose. After reading the chapter "Tales From Two Cities" (the other city being London), I wish I had walked the same streets as the author and Francois Jousse, the man who for more than 30 years has been responsible for lighting the monuments and bridges of Paris. The books is so much more than a portrait of Paris, of course, and I encourage people to evaluate the use of lighting in the world through this book. The Notes section is especially entertaining.
As Charlie tells Sophie, "Books crowbar the world open for you."
