The Universe in You

This microscopic journey moves from the visible world into the increasingly small building blocks of the human body. It begins with comparisons among small living things, including a Calliope hummingbird, butterflies, bees, and fine human hairs. The scale then narrows to skin cells, nuclei, molecules, atoms, and particles. The book reaches quarks and gluons, elementary particles that people cannot currently measure or divide. Its narrative explores how familiar bodies are composed of structures at vastly smaller scales.
