Father's Day is coming.

According to NPR, NASA's new (and free!) 300-page e-book Archaeology, Anthropology, and Interstellar Communication is a fascinating exploration of the question of what would happen if an "information-rich signal emanating from another world" was actually detected. The book features the work of more than a dozen scholars, who look to archaeology and anthropology for clues on how they might decode extraterrestrial messages. I'm not sure how civilian-friendly the science in the book will be, but this sounds like a downright spectacular science-nerd Father's Day gift.
