Planet Rock Doc

Geologist Dr. Elsa Kirsten Peters, also known as the Rock Doc, regularly conveys her enthusiasm for all things science in her nationally syndicated newspaper column. Now she has compiled her favorite essays, along with a few new contributions, into "Planet Rock Doc." With a wry sense of humor, personal anecdotes, and knack for explaining the complex in simple terms, Peters stretches far beyond geology to explore a wide range of contemporary topics and research related to natural and applied sciences. Articles are arranged by subject matter—geology and paleontology, energy and engines, food and agriculture, climate change, human health, biology, physics, chemistry, astronomy, and education and history.
