Book Reviews of Powers of Ten (Revised) (Scientific American Library Paperback)

Book Review: Influential and awe-inspiring
Summary: 5 Stars

The original film was potent too; more so in the directness with which it expresses the scale of the world. But the book, with its annotations and additional pictures, has its own power. You can flip back and forth, and take as much time as you want absorbing the incredible range of scale in the universe.

The book's first picture is scaled at about a billion light years across--ten to the twenty-fifth metres. On this scale even super-clusters of galaxies are just clots of dust on a black background. The right hand side of each page, as you go through the book, zooms in by a factor of ten, and we dive into galaxy clusters, into our galaxy, our spiral arm, our solar system, through the moon's orbit and into the earth's atmosphere, down into North America, and then Chicago, and a picnicker asleep in a park. After twenty five pages we're at a human scale; the pictured scene is a metre across. But the camera continues to zoom in; to the picnicker's hand, through his skin to a lymphocyte, and on down through the cell nucleus to coils of DNA, to a carbon atom and through its electron cloud, and down to the nucleus and beyond. Sixteen pages from the picnicker have brought us to the quarks.

The left hand side of each page provides companion pictures and comments, some drawn from the history of science. For the nanometre picture there's a copy of John Dalton's two-hundred-year-old models of simple molecules; at the millimetre and tenth-millimetre scale there are pictures of radiolaria, seeds, and other microscopic beauties. All are interesting and informative.

I can't recommend this book too strongly--it's a fundamental work of scientific culture, and should be in every house. However, I particularly recommend that you buy this for any nine-to-fourteen-year-old child in your life; it's the best way I know to introduce a child to a love of science.

Summary of Powers of Ten (Revised) (Scientific American Library Paperback)

Starting with a view of a billion light-years, the book (like the film) moves inward, with each page being at one-tenth the scale of the previous one. In 25 steps, you're looking at a picnic by the shores of Lake Michigan, then plunging into a human hand, down through the cells inside it, the DNA inside the cells, the atoms inside the DNA, and the subatomic particles inside the atom. By the time you've gone a total of 40 steps, you're in a world of quantum uncertainty.

There is no better guide to the relative sizes of things in the universe, and no better teacher about what exponential, scientific notation really means. --Mary Ellen Curtin
