While the Earth's oceans are known as five separate entities, there is really only one ocean. So, how big is it? As of 2013, it takes up 71% of the Earth, houses 99% of the biosphere, and contains some of Earth's grandest geological features. Scott Gass reminds us of the influence humans have on the ocean and the influence it has on us.

Lesson by Scott Gass, animation by Sandro Katamashvili.

Explore the history of IQ tests; how they measure a person’s intelligence and the ways they have been used to justify scientifically baseless ideologies.

Uploaded 27-04-20

--

In 1905, psychologists Alfred Binet and Théodore Simon designed a test for children who were struggling in school in France. Designed to determine which children required individualized attention, their method formed the basis of the modern IQ test. So how do IQ tests work, and are they a true reflection of intelligence? Stefan C. Dombrowski explores how the tests have been used throughout history.

Lesson by Stefan C. Dombrowski, directed by Kozmonot Animation Studios.

Marie Brodsky shows how.

Uploaded 07-08-14

Right now, you are inhabited by trillions of microorganisms. Many of these bacteria are harmless (or even helpful!), but there are a few strains of ‘super bacteria’ that are pretty nasty -- and they’re growing resistant to our antibiotics. Why is this happening? Kevin Wu details the evolution of this problem that presents a big challenge for the future of medicine.

Dig into Moore’s Law and explore its 4 main limitations and how they could change how we are able to make progress in computing.

--

Moore’s Law states that every 1 to 2 years the number of transistors that can fit on a given size computer chip will double. Thanks to this law, chips have gotten smaller, faster, more efficient, and cheaper. But today, there are four key problems that trip up this trend, potentially ending Moore’s Law and fundamentally changing how computing progresses. Sajan Saini and George Zaidan investigate.

Lesson by Sajan Saini and George Zaidan, directed by Jeff Le Bars, JetPropulsion.space.

On the dusty roads of a small village, a traveling salesman was having difficulty selling his wares. As he wandered the outskirts of town in the hopes of finding some new customers, he heard a high-pitched yelp coming from the edge of the forest. Following the screams to their source, he discovered a trapped tanuki. Iseult Gillespie details the Japanese myth of the shape-shifting creature.

When reading "Alice's Adventures in Wonderland," most readers visualize the queen’s croquet game play out in their heads. A few might see the scene in vivid detail. However, a small fraction of readers have a drastically different experience: within their heads, they "see" absolutely nothing. Why do some people have an inability to visualize images? Adam Zeman explores the science of aphantasia.
