Loved Cosmos by Carl Sagan? If its nonfiction, astronomy and popular science hooked you, these 20 books hit the same notes — starting with Physics of the Future: How Science Will Shape Human Destiny and Our Daily Lives by the Year 2100, A City on Mars: Can We Settle Space, Should We Settle Space, and Have We Really Thought This Through? and The Future Is Now: Solving the Climate Crisis with Today's Technologies. Every pick is matched by what’s actually inside the book, not just its genre, and we skip other books by the same author so you find someone new.
