  • What if there were 1 trillion more trees? - Jean-François Bastin
    October 27, 2020

    How can trees help in the fight against climate change? Dig into the efforts to rebuild damaged ecosystems and reduce carbon emissions. -- Today humanity produces more than 1,400 tons of carbon every minute. To combat climate change, we need to reduce fossil fuel emissions, and draw down excess CO2 to restore the balance of greenhouse gases. Like all plants, trees consume atmospheric carbon through photosynthesis. So what can trees do to help in this fight? Jean-François Bastin digs into the efforts to restore depleted ecosystems.

  • Can you outsmart the fallacy that started a witch hunt? - Elizabeth Cox
    October 26, 2020

    Dig into the burden of proof fallacy, which assumes that something is true unless proven false and relies on arguments from ignorance. -- It’s 1950. Anti-communist sentiment in the United States is at an all-time high. Senator Joseph McCarthy claims he has a list of communists who are influencing government policy. He makes his first accusation without providing any legitimate evidence, yet the senate committee still schedules a hearing. Can you spot the problem with this hearing? Elizabeth Cox explores the burden of proof fallacy. Lesson by Elizabeth Cox, directed by Pazit Cahlon and Hector Herrera.

Living at the ends of the world's loneliest roads and subsisting off the rugged Alaskan bush, they battle whiteout snow storms, man-eating carnivores, questionable frozen terrain, and limited resources through a long and bitter winter. Some of them are lone wolves; others have their families beside them. All must overcome despairing odds to brave the wild and survive through to the spring. And when spring arrives in Alaska, rising temperatures bring mounting challenges as they work to prepare for yet another winter.

  • The hidden treasures of Timbuktu - Elizabeth Cox
    October 22, 2020

    Dig into the ancient manuscripts, scrolls, and books of Timbuktu— and find out why they’ve been hidden for centuries. -- On the edge of the vast Sahara desert, citizens snuck out of the city of Timbuktu and took to the wilderness. They buried chests in the desert sand, hid them in caves, and sealed them in secret rooms. Inside these chests was a treasure more valuable than gold: the city’s ancient books. Why were they hiding these priceless manuscripts? Elizabeth Cox digs into the literary tradition of Timbuktu. Lesson by Elizabeth Cox, directed by AIM Creative Studios.

  • Why Was the Islamic Golden Age of Science… Golden?
    October 21, 2020

    Around 750-1250 CE, the Islamic empire made incredible scientific advancements that still influence many fields of research today. What we know about some of the great minds of that time, as well as what we’ve learned from modern studies, suggest that the diversity of the scholars and their knowledge during that period might have played a big role in making that golden age what it was.

  • Why the Electoral College Exists | Nat Geo Explores
    October 21, 2020

    Every four years, people head to the polls to vote for the next President of the United States. However, the popular vote doesn't directly elect any candidate. Instead, citizens are voting for a slate of electors, who have promised to cast their states' votes after the election. Today, the Electoral College system is very controversial, leading many people to ask: why does it exist at all? That answer lies in the history of the Constitution and how its creators originally believed America's brand-new government should run and how its leader should be elected. As it turns out, the Electoral College was just as contentious in 1787 as it is today. ➡ Subscribe: http://bit.ly/NatGeoSubscribe ➡ Watch all clips of Nat Geo Explores here: https://bit.ly/NGExplores About Nat Geo Explores: From National Geographic Media, Nat Geo Explores breaks down the worlds of Science, History, and Animals.

  • Pragmatics: Crash Course Linguistics #6
    October 16, 2020

    We don’t always say exactly what we mean, and yet we’re still pretty good at understanding each other. That’s because we don’t just use meaning to figure out what’s going on, we also use context. This episode of Crash Course Linguistics is all about pragmatics, the area of linguistics that deals with context. We’ll cover the four main assumptions we make about context in language, also known as Grice’s Maxims, as well as the ways that languages can use grammar to convey politeness, and the different types of conversational styles within and between languages. Want even more linguistics?

    October 15, 2020

    Discover history’s first empire: Sumer, located in Mesopotamia, which built the world’s first cities and created the first writing system. -- History’s first empire rose out of a hot, dry landscape, without rainfall to nourish crops, without trees or stones for building. In spite of all this, its inhabitants built the world’s first cities, with monumental architecture and large populations— and they built them entirely out of mud. Soraya Field Fiorio details the rise and fall of the Sumerian empire. Lesson by Soraya Field Fiorio, directed by Tomás Pichardo-Espaillat.

  • E/Z Alkenes, Electrophilic Addition, & Carbocations: Crash Course Organic Chemistry #14
    October 14, 2020

    Alkenes are an important type of molecule in organic chemistry that we’re going to see a lot more of in this series. But before we can really get into the many cool reactions alkenes do, we need to go over some of the basics. In this episode of Crash Course Organic Chemistry, we’ll review and build on our knowledge of alkene nomenclature, revisit our friend the carbocation, and learn Markovnikov’s Rule: an important tool that will help us predict the products of addition reactions involving alkenes.

  • Semantics: Crash Course Linguistics #5
    October 9, 2020

    If you want to know what a word means, all you have to do is look it up in the dictionary, right? Actually, it’s a little more complicated than that. This episode of Crash Course Linguistics is all about semantics, or the area of linguistics concerned with meaning. We’ll learn about different types of semantic relationships, and how different languages define these relationships, as well as different approaches to semantics. And we’ll discover that the humble definition may be more complicated than we think. Want even more linguistics?

    October 8, 2020

    Dig into the science of what triggers panic attacks, how to recognize them, and the available treatments for panic disorder. -- Countless poets and writers have tried to put words to the experience of a panic attack— a sensation so overwhelming, many people mistake it for a heart attack, stroke, or other life-threatening crisis. Studies suggest that almost a third of us will experience at least one panic attack in our lives. So what exactly is a panic attack, and can we prevent them? Cindy J. Aaronson investigates.

  • Who owns the "wilderness"? - Elyse Cox
    October 6, 2020

    Explore the creation of national parks and the importance of finding a balance between public use and ecological preservation. -- In 1903, US President Theodore Roosevelt took a camping trip in California’s Yosemite Valley with conservationist John Muir.
