  • Father vs. Son: A descent into the underworld - Joseph Mbele

    Dig into the epic of Mwindo, a boy seeking vengeance upon his power-hungry and murderous father who has fled to the underworld.

    --

    If any of his wives ever birthed a son, he’d be killed immediately. That was the threat Shemwindo, ruler of the village of Tubondo, had delivered, for he wanted all the power to himself. But he was about to meet his match— and enter a rivalry that would take him to the underworld and back. Joseph Mbele shares the epic journey of Mwindo and his quest for vengeance.

    Lesson by Joseph Mbele, directed by Raghav Arumugam, Jagriti Khirwar.

    --

    A fleet of rebel spaceships is greeted by a frenzy of laser blasts – illuminating the sector with brilliant bursts of light. Science fiction has shown us scenes like this for decades, but the lasers in our daily lives seem far less dazzling and destructive. So, could sci-fi laser weaponry ever exist? And how do lasers even work in the first place? Christopher Baird investigates.

    Lesson by Christopher Baird, directed by Igor Ćorić, Artrake Studio.

  • The pioneering work of female explorers - Courtney Stephens

    View full lesson: http://ed.ted.com/lessons/the-contributions-of-female-explorers-courtney-stephens

    During the Victorian Age, women were unlikely to become great explorers, but a few intelligent, gritty and brave women made major contributions to the study of previously little-understood territory. Courtney Stephens examines three women -- Marianne North, Mary Kingsley and Alexandra David-Néel -- who wouldn't take no for an answer (and shows why we should be grateful that they didn't).

    How do we grow crops quickly enough to feed the Earth's billions? It's called the Haber process, which turns the nitrogen in the air into ammonia, easily converted in soil to the nitrate plants need to survive. Though it has increased food supply worldwide, the Haber process has also taken an unforeseen toll on the environment. Daniel D. Dulek delves into the chemistry and consequences.

  • How the Suez Canal shaped global history - Lucia Carminati

    Dig into the construction of the Suez Canal, and discover how it became one of the world’s busiest maritime passages.

    --

    Today, nearly 30% of all global ship traffic passes through the Suez Canal, totaling over 20,000 ships in 2021. The site of the canal had been of interest to rulers as far back as the second millennium BCE, but plans to construct a passageway were obstructed by cost, political strife, and the ever-shifting sands— until the 19th century. Lucia Carminati details the creation of the Suez Canal.

    Lesson by Lucia Carminati, directed by Michael Kalopaidis, Zedem Media.
