    The satisfying math of folding origami - Evan Zodl

    Dig into the mathematical rules and patterns of folding origami, the ancient Japanese art of paper folding. -- Origami, which literally translates to “folding paper,” is a Japanese practice dating back to at least the 17th century. In origami, a single, traditionally square sheet of paper can be transformed into almost any shape, purely by folding. The same simple concepts yield everything from a paper crane with about 20 steps, to a dragon with over 1,000 steps. Evan Zodl explores the ancient art form. Lesson by Evan Zodl, directed by Charlotte Arene.

    Why do we, like, hesitate when we, um, speak? - Lorenzo García-Amaya

    Why do we fill pauses in speech with words like “um,” “uh,” and “like”? Dig into the hesitation phenomenon to find out their linguistic significance. -- For as long as we’ve had language, some people have tried to control it. And some of the most frequent targets of this communication regulation are the ums, ers, and likes that pepper our conversations. These linguistic fillers occur roughly 2 to 3 times per minute in natural speech. So are ums and uhs just a habit we can’t break? Or is there more to them? Lorenzo García-Amaya investigates.

    How do you know if you have a virus? - Cella Wright

    Dig into two testing techniques for viruses: PCR tests to diagnose an infection and immunoassays to detect antibodies. -- A new virus emerges and spreads like wildfire. In order to contain it, researchers must first collect data about who’s been infected. Two main viral testing techniques are critical: one tells you if you have the virus and the other shows if you’ve already had it. So, how exactly do these tests work? Cella Wright explores the science of PCR tests and immunoassays. Lesson by Cella Wright, directed by Hype CG.

    The true story of 'true' - Gina Cooke

    View full lesson: http://ed.ted.com/lessons/the-true-story-of-true-gina-cooke The older the word, the longer (and more fascinating) the story. With roots in Old English, 'true' shares etymological ancestors with words like betroth and truce...but also with the word tree. In fact, trees have been metaphors for steadfastness and faithfulness for as long as the word true has defined the same qualities. Gina Cooke describes the poetic relationship between 'tree' and 'true.' Lesson by Gina Cooke, animation by Brad Purnell. Learn more about your ad choices. Visit megaphone.fm/adchoices

    The death of the universe

    The shape, contents and future of the universe are all intricately related. We know that it's mostly flat; we know that it's made up of baryonic matter (like stars and planets), but mostly dark matter and dark energy; and we know that it's expanding constantly, so that all stars will eventually burn out into a cold nothingness. But is there any beauty in this dark ending? Animation by Giant Animation Studios. Learn more about your ad choices. Visit megaphone.fm/adchoices

    Ida B. Wells was an investigative journalist, civil rights leader, and anti-lynching advocate who fought for equality and justice. -- In the late 1800’s, lynchings were happening all over the American South, often without any investigation or consequences for the murderers.

    Why doesn't everyone have a jetpack? - Richard Browning

    Explore the physics of how jetpacks fly, and discover the technology that allows pilots to maneuver the engines. -- In 1961, Yuri Gagarin piloted a spacecraft in humanity’s first manned space flight. A week later, Bell Aerosystems debuted a gas-powered rocket pack that could fly 35 meters in 13 seconds. Unfortunately, engineers knew this short flight was all the rocket pack could muster. So why was a massive spacecraft easier to send flying than a single pilot? Richard Browning investigates.
