Einstein started a book club, and here's the reading list
What the beloved genius and his buddies discussed in the Olympia Academy is legendary.
'Don Quixote' by Miguel de Cervantes
"Don Quixote" is the sword in the stone of high school Spanish classes worldwide. In this novel, a noble named (guess who) Don Quixote decides that being an old-timey knight would be awesome. Everyone thinks he's crazy since he's a few hundred years too late for the feudal system.
He ends up going on various absurd quests and finally confuses a windmill with a giant and fights it to death (his death, not the windmill's).
Plus, a character says, "Thou hast seen nothing yet." The book was written in Spanish, meaning a translator amazingly put that sentence together.
The book explores a lot of philosophical themes that probably interested the Olympia Academy's young men.
