Medusa, transformed into a monstrous Gorgon by a wrathful Athena, sought refuge in a hidden cave. Time after time, would-be heroes journeyed to the cave to make their names by murdering Medusa— but fell to her gaze every time. Until another young man, Perseus, began his quest for glory. Laura Aitken-Burt shares the myth of Medusa and her infamous power to petrify.

Lesson by Laura Aitken-Burt, directed by Yael Reisfeld.

Dig into the mathematical rules and patterns of folding origami, the ancient Japanese art of paper folding.

Uploaded 11-02-21

--

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.

When you listen to music, multiple areas of your brain become engaged and active. But when you actually play an instrument, that activity becomes more like a full-body brain workout. What's going on? Anita Collins explains the fireworks that go off in musicians' brains when they play, and examines some of the long-term positive effects of this mental workout.

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.

Uploaded 18-02-21

--

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.

Dig into two testing techniques for viruses: PCR tests to diagnose an infection and immunoassays to detect antibodies.

Uploaded 18-05-20

--

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.

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.'

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?
