Coral reef fish, like the yellow tang surgeonfish, begin life in a fascinating and weird way – as tiny floating larvae! These babies are capable of drifting thousands of miles on ocean currents, far from the reefs where they were born. Amy McDermott describes how these tiny trekkers travel across vast oceans, searching for the far-flung reefs they will one day call home.

Dive into the Greek myth of Helios and Phaethon, where the Sun God allows his mortal son to drive his chariot for a day.

Uploaded 18-01-22

--

Every morning, Helios unleashed his golden chariot, and set out across the sky. As the Sun God transformed dawn into day, he thought of his son, Phaethon, below. To prove to Phaethon that he was truly his father, Helios decided to grant him anything he wanted. Unfortunately, what Phaethon wanted was to drive Helios’ chariot for a day. Iseult Gillespie shares the tragic myth of the charioteer.

Lesson by Iseult Gillespie, directed by Raghav Arumugam and Jagriti Khirwar.

We make important decisions every day -- and we often rely on experts to help us decide. But, says economist Noreena Hertz, relying too much on experts can be limiting and even dangerous. She calls for us to start democratizing expertise -- to listen not only to "surgeons and CEOs, but also to shop staff."

Talk by Noreena Hertz.

Investigate the theories surrounding cosmic dust bunnies and discover how the tiny particles could hold the key to the formation of life on Earth.

Consider the spot where you’re sitting. Travel backwards in time and it might’ve been submerged at the bottom of a shallow sea, buried under miles of rock or floating through a molten landscape. But go back about 4.6 billion years, and you’d be in the middle of an enormous cloud of dust and gas orbiting a newborn star. What exactly is this cosmic dust? Lorin Matthews investigates.

Lesson by Lorin Swint Matthews, directed by Frederic Siegel (Team Tumult).

Discover how scientists developed atomic clocks, which use the vibrations of atoms to measure and maintain a globally consistent time.

Uploaded 19-01-21

--

In 1967, researchers gathered to answer a long-running scientific question: just how long is a second? It might seem obvious at first. A second is the tick of a clock, the swing of a pendulum, the time it takes to count to one. But how precise are those measurements? And what is that length based on? John Kitching digs into how we scientifically define this fundamental unit of time.

Lesson by John Kitching, directed by Tjoff Koong.

When the son of the president of a desperately poor country starts buying mansions and sportscars on an official monthly salary of $7,000, Charmian Gooch suggests, corruption is probably somewhere in the picture. In a blistering, eye-opening talk (and through several specific examples), she details how global corruption trackers follow the money -- to some surprisingly familiar faces.
