Explore the possibility of transitioning to a green economy, and if the trillion-dollar up-front cost is worth the investment.

--

Global warming is very, very expensive: extreme weather, rising sea levels, crop failures, health issues, and industry disruptions all cost money. So, what’s the best way forward? Is the estimated trillion-dollar price tag that comes with transitioning the world to clean energy worth the cost of investment? George Zaidan explores what it would take to become a green economy.

Lesson by George Zaidan, directed by Sofia Pashaei.

Dive into Herman Melville’s classic novel “Moby Dick,” the story of Captain Ahab’s hunt for revenge against the white whale who bit off his leg.

Uploaded 26-05-20

--

A mountain separating two lakes. A room papered floor to ceiling with bridal satins. The lid of an immense snuffbox. These seemingly unrelated images take us on a tour of a sperm whale’s head in Herman Melville’s "Moby Dick." Though the book features pirates, typhoons, high-speed chases, and giant squid, it’s anything but a conventional seafaring adventure. Sascha Morrell digs into the classic novel.

Lesson by Sascha Morrell, directed by Martina Meštrović.

Take a journey into the respiratory system to see how ventilators bypass constricted airways and help damaged lungs send oxygen to the body.

Uploaded 21-05-20

--

In the 16th century, physician Andreas Vesalius described how a suffocating animal could be kept alive by inserting a tube into its trachea and blowing air to inflate its lungs. Today, Vesalius’s treatise is recognized as the first description of mechanical ventilation— a crucial practice in modern medicine. So how do our modern ventilators work? Alex Gendler explains the life-saving technology.

Puzzle through the ethical dilemma of intellectual property rights, and decide: how should we determine ownership of work?

--

In the city of Ockham, spellcasters invent incantations and publish them in scrolls that others can purchase. Unfortunately, you can’t always afford them. But one day, a friend tells you he uses an illegal duplication spell to copy scrolls. So, do you use his counterfeit scrolls to further your own research? Michael Vazquez and Will Kanwischer explore the ethics of intellectual property rights.

Lesson by Michael Vazquez and Will Kanwischer, directed by Patrick Smith.

Travel into the digestive system to see how food is turned into waste, and what causes the different colors and textures of poop.

--

The average person poops out approximately 11,030 kilograms of cumulative waste in a lifetime. That’s the equivalent of more than 6 SUVs. Oftentimes, that poop is brown. Why is that, considering all the comestibles one consumes? And what’s going on when poop appears in different colors and textures? Hannibal Person explains the colorful choreography going on inside your bowels.

Lesson by Hannibal Person, directed by Flávia Godoy, Lívia Serri Francoio.

Uploaded 15-07-14

We typically experience classic works of art in a museum, stripped of their original contexts, but that serene setting can belie a tumultuous history. Take Michelangelo's statue of David: devised as a religious symbol, adopted as a political emblem, and later iconized for its aesthetic beauty. James Earle walks us through the statue's journey, to show how art gains layers of meaning over time.

Explore how greenhouse gas emissions impact global warming and why it’s necessary to get emissions down to net zero.

Uploaded 16-02-21

--

Since 1850, global average temperatures have risen by 1 degree Celsius. That may not sound like a lot, but it is. Why? 1 degree is an average. Many places have already gotten much warmer and if average temperatures increase one more degree, the coldest nights in the Arctic might get 10 degrees warmer. So how did we get here? And what can be done? Explore the challenges of net zero emissions.

When Sue Austin got a power chair 16 years ago, she felt a tremendous sense of freedom -- yet others looked at her as though she had lost something. In her art, she aims to convey the spirit of wonder she feels wheeling through the world. Includes thrilling footage of an underwater wheelchair that lets her explore ocean beds, drifting through schools of fish, floating free in 360 degrees. (Filmed at TEDxWomen.)
