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.

When presented with the problem of hoards of illiterate commoners, English clergymen in the 11th century created plays to spread word about the Bible. Eventually, the plays moved out of the church and into the streets. Mindy Ploeckelmann tracks the development of drama from mystery plays to morality plays and, eventually, to Shakespeare.

--

The species of slug known as Elysia chlorotica may not look like much— it resembles a bright green leaf— but it’s one of the most extraordinary creatures on our planet. Living in marshes along the coast of North America, it can go about a year without eating. During that time, it lives like a plant. How is this possible? Luka Seamus Wright digs into the incredible adaptations of these mixotrophs.

Dig into how scientists are attempting to revive the functionally extinct northern white rhino through artificial reproduction.

Uploaded 13-08-20

--

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.

Discover how alcohol impacts your body’s processes and causes hangovers, and find out what causes the most common hangover symptoms.

--

The molecule responsible for hangovers is ethanol, which we colloquially refer to as alcohol. Ethanol is present in all alcoholic beverages, and generally speaking, the more ethanol, the greater the potential for a hangover. So, how exactly does alcohol cause a hangover— and is there any way to prevent one? Judy Grisel explores the surprising ways that alcohol affects the body.

Lesson by Judy Grisel, directed by Anton Bogaty.

More than 2 kilometers below the surface of northern Ontario, suspended in 345,000 liters of ultra-pure water, there’s a perfect sphere. Scientists continuously monitor this chamber, looking for a glimmer of light in the darkness. Why? Because that light would indicate the presence of one of the universe’s greatest mysteries: dark matter. Jenna Saffin describes how this dark matter detector works.
