Several years ago, when Neil deGrass Tyson was on Reddit’s popular Ask Me Anything (AMA), he was asked a particularly insightful question by Reddit user ElCracker: Which books should be read by every single intelligent person on planet?
His answers might not surprise you, but the fact that all of the books are free and readily available online is a feat of technology that makes the internet a marvel. Here, we list the books as prescribed by Tyson and their relevant links to the eBooks version on the Project Gutenberg Project and their audiobooks on Librivox. We think they’re perfect classics to start your new year’s reading lists. Enjoy!
