Kathryn Schultz’ New Yorker review of “Invisible: The Dangerous Allure of the Unseen” (Chicago), by Philip Ball, is a brief and clearly-written read, with a sharply focused ending:

“…I cannot see the people I love as I write this, but I can sense their pull, and I act as I do because of their existence. Taken literally, that is how the cosmos works. An invisible mass alters the orbit of a comet; dark energy affects the acceleration of a supernova; the earth’s magnetic field tugs on birds, butterflies, sea turtles, and the compasses of mariners.  The whole realm of the visible is compelled by the invisible. Our planet, our solar system, our galaxy, our universe: all of it, all of us, are pushed, pulled, spun, shifted, set in motion, and held together by what we cannot see”.
