Ever since I read Italo Calvino's Invisible Cities (1972) and David Eagleman's Sum (2009), I've been interested in magical realism -- a playful, imaginative curiosity that, lately, has even snuck into my own writing.

Lightman's perspective on the genre I've particularly enjoyed given his background as an MIT physicist. So, I was excited when, once again prowling the stacks of Half Priced Books, I came across Mr. g: A Novel About the Creation (Vintage, 2012). ... Mr g is a first-person-except-when-it's-not narrative about God's creation of the universe (or rather a universe). Tolerating the squabbles and input of his Aunt Penelope and Uncle Deva, Mr g introduces space and time to "The Void" (the non-dimensional realm they inhabit), deciding thereafter to create a universe merely to keep himself occupied. Beginning with a few "organizing principles" (natural laws), he spends most of his time fawning over the harmony of the cosmos' as they effectively create themselves. In the book as in nature, it is rules that govern and build not a spirit's hands. Thus emerge stars and the fusion of basic elements to create more, which in clicks of the atomic clock form the richness of planets, solar systems, galaxies. The way Lightman lies out this natural progression -- leading to the emergence of life -- was where I found his prose most engaging. Unfortunately, when this life becomes intelligent, moral, that his writing slipped away. ...
