[00:00:00]This Persian scholar risked everything to save human knowledge from complete destruction. Around 1260, Mongol armies were burning libraries across the Islamic world. Centuries of Greek philosophy, Persian medicine, and mathematical breakthroughs were going up in flames. But, Nasir al-Din al-Tusi had a dangerous plan. He convinced the Mongol Khan to fund what looked like an astronomy project, the Maragheh Observatory. But, secretly, he was running the greatest rescue operation in history. While serving his Mongol rulers by day, al-Tusi was training scholars to copy and hide thousands of manuscripts by night. One wrong move meant death. He even made his own breakthrough, the Tusi couple, solving major problems with ancient astronomy 250 years before Copernicus. His students smuggled the saved knowledge across Europe and Asia.

[00:00:54]Greek texts that would have been lost forever, advanced algebra, medical discoveries. Here's the incredible truth. The Renaissance happened because of what this man saved. Every scientific advance Europe claimed built on knowledge al-Tusi rescued from the flames. He literally saved human civilization, and almost no one knows his name.
