Great new episode with Harvard University geologist Andrew Knoll who chats about the grand sweep of Earth’s history.
Harvard University geologist Andrew H. Knoll takes on the grand sweep of Earth’s formation and evolution in his new book A Brief History of Earth: Four Billion Years in Eight Chapters. He succinctly describes Earth from its cosmological beginnings in a molecular cloud on through to the present day. It’s a fine line between the vacuum of space and the planet on which we walk.
