Whether you identify as a wayfinding whiz or get lost returning from the grocery store, your brain has a built-in navigation system that facilitates spatial skills, from sensing which direction is north to map-reading and route-learning. So, why do we still struggle to find our way? And why do some of us find ourselves lost more often than others? Oliver Baumann digs into our sense of direction.

Lesson by Oliver Baumann, directed by Anton Bogaty.

You enter your living room, then pause. Uh-oh, what was it that you were doing? You feel your mission’s momentum wane, and its aim is suddenly lost. So, what just happened? Well, you’re not alone; this is a common memory lapse phenomenon scientists have termed the “doorway effect.” Gabriel Radvansky explores why walking into a new space can make you suddenly forget what you were doing.

In 1930, in hopes of supporting farms and manufacturing, President Hoover made a bold decision: he approved a sweeping 20% tax on all imported agricultural and industrial goods. But the plan completely backfired, leading exports to fall and global trade to decline. And it wouldn't be the last time a world leader was shocked by a tariff’s consequences. Trace the economic chain reaction of tariffs.

This is episode 7 of the animated series, “Public Speaking 101.” Ideas change everything — and since language lets us share our ideas, learning how to use it well gives speakers the power to inspire people and even change how they think. This 11-episode course will teach you how to identify, develop, and share your best ideas, while mastering essential communication skills along the way.

Directed by Tolga Yıldız, Kozmonot Animation Studio.

The TED-Ed Student Talks program provides free, customizable activities for educators to support their students in identifying, developing and sharing their ideas with each other and the world. Learn more at https://ed.ted.com/student_talks

Imagine a ship struggling in an endless storm. Its captain, though strong and commanding, is a terrible navigator. Neither he nor his crew have been trained to sail, yet they tirelessly vie for control through bribery, flattery, and mutiny, and ignore those with real navigation knowledge. This dysfunctional vessel is Plato's Ship of State. Michael Vazquez explores the infamous thought experiment.

Lesson by Michael Vazquez, directed by Luis Torres, Mr. Flama.

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.

As a young woman, Cassandra of Troy had been pursued by the god Apollo, who offered her the gift of prophecy. But when she withdrew from his advances, he twisted his gift into a maddening hex: from that day on, Cassandra would be able to precisely see and describe the future— but her prophecies would never be believed. Iseult Gillespie details the Greek tragedy of the cursed seer.

To coincide with the 1964 Tokyo Olympics, Japan launched a groundbreaking bullet train that inspired countries around the world to invest in high-speed rail. Today, high-speed trains regularly travel at over 300 km/h, on par with the take-off speed of a commercial airplane. But can it ever be faster than flying? Ning Zhao details the possibilities and hurdles facing high-speed rail transit.

After hours of delay, your flight is finally boarding. But as the line grinds to a halt, you can’t help but think — there must be a faster way to board this plane. Mathematicians have been studying this problem for years, devising and testing a range of different boarding methods. Rachel Yang digs into our biggest plane-loading bottlenecks and potential methods to alleviate this travel headache.

Spices are often far pricier proportionately than the foods they flavor. But one’s cost has long topped them all. Saffron’s red threads regularly run at rates of over 600 USD an ounce. So what is this so-called “red gold,” and what makes it so expensive? Carolyn Beans digs into the unique biology of saffron and humanity's enduring obsession with the spice.

Like any other plant, kelps require light to grow. Yet kelps found nearly 90 meters below the ocean's surface, where sometimes only 0.1% of sunlight can reach, grow as large as, and often even larger than, their shallow counterparts. So how have these large, light-dependent organisms adapted to thrive at such depths? Luka Seamus Wright and Salomé Buglass explore the ocean's hidden forests.

Lesson by Luka Seamus Wright and Salomé Buglass, directed by Upamanyu Bhattacharyya, Otter Studios.

Passports are not the first form of travel documents: in Ancient Egypt, travelers carried “letters of safe conduct” issued by rulers; in Han China and Tudor England, foreigners were issued travel passes. However, for much of human history, borders have been relatively fluid, and travel lacked bureaucratic requirements. So, what changed? Kristin Surak details the history of the passport system.

For over 25 years, the International Space Station’s air supply systems have revolutionized space missions. Yet the need for regular maintenance, repairs, and upgrades has pushed engineers to develop even more reliable systems for future spacecraft. How do we create breathable air in space? And what does that look like for longer expeditions? Alvaro Romero-Calvo and Theo St Francis investigate.

Lesson by Alvaro Romero-Calvo and Theo St Francis, directed by Lazy Chief.

The diverse fungal kingdom, which includes everything from baker’s yeast to edible mushrooms to foot infections, has long defied assumptions. Scientists estimate that somewhere between 2 and 12 million species of fungi remain undiscovered— either because they’re microscopic, live hidden within other species, or for other unknown reasons. Max G. Levy digs into the vast and wild world of fungi.
