How Humanity Lost Most of Its Knowledge

You think knowledge, once written down, is safe forever. But for most of human history, that wasn't true. It could burn. It could rot. It could simply be forgotten by the one civilization that remembered how to read it. In this video, you'll discover how the greatest library ever built, the Library of Alexandria, gathered the accumulated knowledge of the ancient world, and how that knowledge didn't vanish in a single fire, but through centuries of neglect, war, funding cuts, and quiet indifference. You'll see how entire fields of ancient science, mathematics, and medicine were lost, some rediscovered a thousand years later, some never recovered at all. And you'll understand why the fragility of knowledge is a lesson that still applies to the world you live in today.
