Now we can finally grasp the grandeur and complexity of these ideas, and their significance in our lives. Revised and updated to include the latest discoveries that are changing the way we view the world and the universe, this new edition of The Science Class You Wish You Had will take you on a journey through space and time--from the subatomic to the universal. It explains in a lively, accessible way what these milestones of scientific discovery mean and what direct impact they have on our lives today and will have in the future. For everyone interested in science, history, and biographies of extraordinary people--or anyone who wants to understand the workings of the physical world--this thorough and authoritative book is a perfect introduction to science's most profound discoveries, and a testament to the triumph of human knowledge.
