The Persistence of Memory

   1980    Science
The idea of intelligence is explored in the concepts of computers (using bits as their basic units of information), whales (in their songs and their disruptions by human activities), DNA, the human brain (the evolution of the brain stem, frontal lobes, neurons, cerebral hemispheres, and corpus callosum under the Triune Brain Model), and man-made structures for collective intelligence (cities, libraries, books, computers, and satellites). The episode ends with speculation on alien intelligence and the information conveyed on the Voyager Golden Record.

Alexandria

   2020    History
Feast your eyes on a reconstruction of the mega-city and its amazing buildings. Alexandria, built in the middle of rancid marshland, had become in less than a century, the greatest city of the Mediterranean. An ideal position at the crossroads of east and west, and one that brought her great riches. Huge, modern, gleaming white and cosmopolitan, like no other in antiquity, it created its own identity.
While the beauty of its planning, its great arteries, its temples and its ports would be equalled only by its openness to the rest of the world. And the monumental achievements of its sovereigns, still shrouded in mystery, we'll never cease to fire our imagination for millennia to come.

The Librarians

   2025    Culture
Across the United States, a growing wave of censorship is turning libraries into battlegrounds. This gripping documentary follows a group of librarians in Texas, Florida, and beyond who refuse to stay silent as book bans spread through schools and communities. What begins as a local fight over reading lists becomes a powerful defense of free thought, truth, and democracy itself. Through emotional testimonies and scenes of quiet defiance, the film reveals how the right to read is being tested like never before.
As pressure mounts from political groups and extremist movements, these librarians stand their ground—facing threats, intimidation, and public outrage to protect the stories that shape us all. Their courage transforms a profession built on order and access into a movement for freedom, reminding us that knowledge, once lost, is the hardest thing to reclaim.
