Chin follows his acclaimed Your Place in the Universe (rev. 11/20) with an equally stellar exploration of the tiniest components of matter conceptualized by science. The book opens with a brown-skinned child who uses a wheelchair visiting a Southwestern desert. The United States’ smallest bird, butterfly, and bee, in turn, alight on her finger, in close-ups that ultimately zoom in to a hair on that finger and put in motion a journey inward to the “building blocks” of biology and physical science.
