Skunk Works: A Personal Memoir of My Years at Lockheed

A Short History of Nearly Everything (Bill Bryson). It's a cursory overview of all of history (title) from the dawn of time to the evolution of humans. It seems to be only slightly dated in some information, but really interesting to learn how the knowledge we assume is true today came to fruition over time. Before that, Skunk Works: A Personal Memoir of My Years at Lockheed (Ben R. Rich) Such an awesome book about not only the engineering feats achieved by Lockheed Martin during the Cold War Era, but the incredible ability to keep developments secret from the mostly everyone. If you want to know more about the purpose of Area51, check it out.
