Why aren’t commercial flights getting faster? Dig into the technological and environmental problems facing supersonic flight. -- In 1996, a British Airways plane flew from New York to London in a record-breaking two hours and fifty-three minutes. Today, however, passengers flying the same route can expect to spend no less than six hours in the air — twice as long. So why, in a world where everything seems to be getting faster, have commercial flights lagged behind? Alex Gendler details the problems facing supersonic flight.

Explore the circular reasoning fallacy, which occurs when the end of an argument comes back to the start without having proven itself. -- It’s 1990. A prospective student has filed a complaint about Virginia Military institute’s admissions policy that excludes women. The state argues that VMI’s single sex education is an “important governmental objective” and that the exclusion of women from VMI is essential to that objective. Can you spot the problem with this argument? Elizabeth Cox explores the circular reasoning fallacy. Lesson by Elizabeth Cox, directed by TOGETHER.

Find out whether a honeybee, a tarantula hawk wasp, or a bullet ant has the most painful insect sting, and what each of their stings feel like. -- One of these three creatures is thought to possess the world’s most painful insect sting: there’s an ant that forages in rainforest canopies, a bee that protects a hive of delectable honey, and a wasp that paralyzes tarantulas. So which has the nastiest sting? Justin Schmidt describes and ranks the pain inflicted by each insect. Lesson by Justin Schmidt, directed by Nicholas Paim, Alopra Studio.

Dig into how scientists are attempting to revive the functionally extinct northern white rhino through artificial reproduction. -- In the savannahs of Kenya, two female northern white rhinos, Nájin and Fatu, munch contentedly on grass. They are the last two known northern white rhinos left on Earth. Their species is functionally extinct— without a male, they can’t reproduce. And yet, there’s still hope to revive the northern white rhino. How can that be? Jan Stejskal dives into the science of reviving a dying species. Lesson by Jan Stejskal, directed by Denis Chapon.

For some reason, says educator Al Vernacchio, the metaphors for talking about sex in the US all come from baseball -- scoring, getting to first base, etc. The problem is, this frames sex as a competition, with a winner and a loser. Instead, he suggests a new metaphor, one that's more about shared pleasure, discussion and agreement, fulfillment and enjoyment. Let's talk about ... pizza. Talk by Al Vernacchio.

Get to know how a healthy marine ecosystem functions, and what creates the lethal conditions that lead to dead zones. -- For most of the year, the Gulf of Mexico is teeming with marine life, from tiny crustaceans to massive whales. But every summer, disaster strikes. Around May, animals begin to flee the area. And soon, creatures that can’t swim or can’t swim fast enough begin to suffocate and die off in massive numbers.

Explore how wind turbines convert wind into electricity, and the challenges of powering the world entirely with wind energy. -- Every 24 hours, wind generates enough kinetic energy to produce roughly 35 times more electricity than humanity uses each day. And unlike coal or oil, this resource is totally renewed each day. So how can we harness this incredible amount of energy, and is it possible to create a world powered entirely by wind? Rebecca Barthelmie and Sara Pryor dig into the science of wind turbine technology. Lesson by Rebecca J. Barthelmie & Sara C. Pryor, directed by Gavin Edwards, Movult.

Explore the science of what causes total solar eclipses, and find out how civilizations throughout history reacted to them. -- How can the shadow of the tiny moon eclipse the sight of the gargantuan sun? By sheer coincidence, the disc of the sun is 400x larger than the disc of the moon, but it's 390x farther from Earth -- which means that when they align just right, the moon blocks all but the sun's glowing corona. Andy Cohen details this extraordinary celestial phenomenon (and when it will next occur). Lesson by Andy Cohen, animation by Bevan Lynch.
