Solar power is cheaper and more sustainable than our current coal-fueled power plants, so why haven't we made the switch? The real culprits here are the clouds, which make solar power difficult to control. Alexandros George Charalambides explains how solar towers and panels create electricity and how scientists are trying to create a system that can function even under cloud cover.

Lesson by Alexandros George Charalambides, animation by Ace and Son Moving Picture Co., LLC.

Ragnarok: The fabled end of the world, when giants, monsters, and Norse gods battle for the future. The gods were winning until the great serpent Jörmungandr emerged. It swallowed Valhalla and contorted itself across the land. Odin has just enough power to strike with one final bolt of lightning, and you have the fabled hammer, Mjölnir. Can you two destroy the serpent? Dan Finkel shows how.

Lesson by Dan Finkel, directed by Artrake Studio.

Solve this classic game theory challenge: given integers from 0 to 100, what would the whole number closest to ⅔ of the average of all numbers guessed be?

Uploaded 05-11-19

--

Given a range of integers from 0 to 100, what would the whole number closest to 2/3 of the average of all numbers guessed be? For example, if the average of all guesses is 60, the correct guess will be 40. The game is played under conditions known to game theorists as “common knowledge:” every player has the same information— they also know that everyone else does too. Lucas Husted explains.

How can animation convey complex, intangible concepts? A visual metaphor, or an idea represented through imagery, can take an idea as massive as Big Data and tie it to the familiar depiction of a growing tree. TED-Ed animators explain how to make an abstract idea come alive visually.

In 1980, philosopher John Searle developed a thought experiment in response to AI advancement at the time. His aim was to interrogate whether a programmed computer has cognitive states, and asked: if a computer looks like it understands something, does that mean it actually understands the way a human does? Charles Wallace and Dan Kwartler explore whether or not AI could have a mind like ours.

Lesson by Charles Wallace and Dan Kwartler, directed by Hernando Bahamon, Vicente Numpaque, Globizco Studios.

Puzzle through the ethical dilemma of a spouse accused of murder and decide: do you believe your spouse or the evidence?

--

You’re sitting on the couch, when you hear a knock on the door. The police have arrived to arrest your spouse— for murder. This accusation comes as a total shock, but their fingerprints were found on the murder weapon. Your spouse insists they’re innocent. Should you believe your spouse, even though the evidence against them looks damning? Alex Worsnip takes a look at this classic ethical dilemma.

Lesson by Alex Worsnip, directed by Emily Howells and Aaron Brady.

This video was produced in collaboration with the Parr Center for Ethics, housed within the renowned Philosophy Department at the University of North Carolina at Chapel Hill. The Parr Center is committed to integrating abstract work in ethical theory with the informed discussion of practical ethical issues, and prides itself on the development of innovative and inclusive approaches to moral and civic education.

Is there a best sleep position? Dig into how sleeping on your side, back, or stomach can impact your body and health.

--

Sleep positions go by countless creative names— the zombie, mountain climber, free faller, soldier, and more. Yet sleep experts typically simplify them into the basic types: side, stomach, or back. Individual sleep styles are highly personal, but how we spend the night affects our bodies and health in several ways. So, what’s the best position to sleep in? Rachel Marie E. Salas investigates.
