Robert M. Hazen’s exciting explanations of how the Earth and its geologic and biologic systems formed and changed had my head spinning with growing knowledge and dawning comprehension. About five billion years ago—several billion years after the Big Bang, which Hazen explains well enough for me to finally grasp, somewhat—an event such as a shock wave from an exploding star caused a cloud of gas and dust to collapse into a star system, our Solar System. “Like a twirling ice-skater, the big cloud rotated faster and faster as gravity pulled its wispy arms to the center. As it collapsed and spun faster, the cloud became denser and flattened into a disk with a growing central bulge—the nascent Sun.” Scientists can’t say for sure how the planets formed, but because all the planets more or less rotate in the same direction and are more or less on the same plane, Hazen explains, most scientists speculate that the planets formed from the same rotating gas and dust as the Sun, and were not objects hurtling through space captured by the Sun’s gravitational pull, as was once thought.
The Earth has gone through many drastic changes since forming. The names of the chapters in The Story of Earth illustrate this: Black Earth: The First Basalt Crust; Blue Earth, The Formation of the Oceans; Gray Earth: The First Granite Crust; Living Earth: The Origins of Life; Red Earth: Photosynthesis and the Great Oxidation Event; The “Boring” Billion: The Mineral Revolution (Surprise: these billion years were anything but boring!); White Earth: The Snowball-Hothouse Cycle; Green Earth: The Rise of the Terrestrial Biosphere. I’ve never really imagined our planet as anything other than a grey ball of rock slowly turning blue and green as life began. This book shows how that view is far from accurate.
The Moon, too, has changed over the billions of years. Did you know that it is moving away from the Earth by about 3.82 centimeters per year? Scientists know this because Apollo astronauts left mirrors on the surface of the moon in the 1960s and 70s, and scientists measure the distance very accurately by bouncing laser beams off them. If the moon is moving away from the earth at that rate, can you imagine how close the moon was to the earth 4.5 billion years ago? It would have looked gigantic. The surface of the Moon was quite different back then, too. According to Hazen, “The early Moon was a violent body of intense volcanism, quite unlike the static silvery-gray object we see now. Its surface would have appeared black, with glowing red magma-filled cracks and volcanic basins easily visible from Earth.” Hazen explains the current theory of how the Moon was formed by what he calls “The Big Thwack,” or the giant impact theory.
4.5 billion years is an unfathomably long time. In 283 pages, Hazen is able to clarify to someone like me, who never took many science classes, the current theories of how Earth and the Moon formed, how life began, how mineralogical forces influence life and how life in turn influences mineralogy, and many other fascinating phenomena. One of the more interesting sections was of the Great Oxidation Event, something I had heard about but had never understood. He writes about how he and his colleagues figured out that many of the minerals we see today—turquoise, azurite, malachite, and thousands of others—could never have occurred without the Great Oxidation Event, and thus how such minerals would never be found on a non-living astronomical body like the Moon or Mars.
If you have an interest in this planet on which we’re living, and you want to know more about how it got here, how it has changed throughout the estimated 4.5 billion years since it formed, and where it may be going, read this book. It’s fascinating.

A new Oliver Sacks book is always an anticipated event, as the library’s hold list for this book shows. His blend of scientific accuracy, accessible writing style, and empathy for his subject shine through. It also means that his 12 books are still in print even though the first one, Awakenings, was published almost 40 years ago. Williamsburg Regional Library owns Awakenings and seven of his other books and they are still flying regularly off the library shelves. My colleague, Barry, wrote about
Did you know that rabies still kills 55,000 people worldwide every year? And that there are plausible connections between rabies and the myths of werewolves, vampires, and zombies?




Grzimek’s Animal Life Encyclopedia lives up to its name. It is definitely an encyclopedia, with 17 huge volumes. I don’t necessarily want to admit to being a nerd who reads the encyclopedia for fun but this one is worth a second look, particularly for animal lovers. Our library has two sets of Grzimek’s and the set shelved at the James City County Library in Croaker Road can be checked out (and requested for library users who prefer to go to the Williamsburg branch), so I challenge anyone who is fascinated by books like 


I have to admit that I picked up We Have Met the Enemy: Self-Control in an Age of Excess because I thought it would annoy me. I saw a bomb made out of a chocolate-coated doughnut on the cover and thought, “Another screed blaming all the world’s ills on people the author considers fat!” I was annoyed less than I anticipated, laughed, and even learned, more than I anticipated.
Like many who have traveled I am intimately aware that umpteen people around the world have dirty, nasty, and awkward toilet facilities. It is great to see the world but sometimes even better to get back to my own bathroom. What I didn’t realize before reading The Big Necessity is that “2.6 billion people don’t have sanitation … Four in ten people have no access to any latrine, toilet, bucket, or box.”
