The myth of Loki and the master builder - Alex Gendler
Dive into the Norse myth of how Loki tricked a stranger into building the great wall of Asgard to keep the realm safe from giants. -- Asgard, a realm of wonders, was where the Norse Gods made their home. There Odin’s great hall of Valhalla towered above the mountains and Bifrost, the rainbow bridge, anchored itself. Though their domain was magnificent, it stood undefended from the giants and trolls who sought to destroy them. But a stranger appeared and made the gods an offer. Alex Gendler details the myth of the master builder. Lesson by Alex Gendler, directed by Hype CG.

On being a woman and a diplomat - Madeleine Albright
View full lesson: http://ed.ted.com/lessons/madeleine-albright-on-being-a-woman-and-a-diplomat In a frank and funny Q&A with Pat Mitchell from the Paley Center, former U.S. Secretary of State Madeleine Albright talks bluntly about politics and diplomacy, making the case that women's issues deserve a place at the center of foreign policy. Far from being a "soft" issue, she says, women's issues are often the very hardest ones, dealing directly with life and death. Since leaving office as U.S. Secretary of State in 2001, Madeleine Albright has continued her distinguished career in foreign affairs as a businesswoman, political adviser and professor.

The most widespread falsehoods about Neanderthals - Bruce Hardy
Dig into the surprisingly complex lives of Neanderthals, and explore theories on what happened to our evolutionary cousins. -- In 1856, quarriers working in Germany’s Neander Valley discovered several mysterious fossils. The remains changed hands until being identified as the skullcap and femur bones of something ancient and human, but not quite us. It soon became clear they belonged to an extinct human species— the first ever known to science: Neanderthals. Bruce Hardy explores what happened to our evolutionary cousins.

Why every world map is wrong - Kayla Wolf
Dig into the inaccuracies of flat maps and how different map designs can shift our point of view. -- Fourteen Greenlands could fit in Africa— but you wouldn’t guess it from most maps of the world. The fact is, every world map humans have ever made is wrong. Actually, it’s impossible to make a flat map of the whole spherical world 100% right. So why do we bother with these inaccurate maps at all? Kayla Wolf explores how even the simplest changes in map design can shift our point of view.

Can you outsmart the apples and oranges fallacy? - Elizabeth Cox
Dig into the false analogy fallacy, which assumes that because two things share a characteristic, they must be alike in other respects. -- It’s 1997. The United States Senate has called a hearing about global warming. Some expert witnesses point out that past periods in Earth’s history were warmer than the 20th century. Because such variations existed long before humans, they claim the current trend is also the result of natural variation. Can you spot the problem with this argument? Elizabeth Cox explores the false analogy fallacy. Lesson by Elizabeth Cox, directed by TOGETHER.

Do tax cuts invigorate the economy? - Jonathan Smith
Dig into trickle-down economics, which claims that tax cuts for corporations and the wealthy stimulate the economy and improve people's lives. -- In 1981, the US economy was struggling: unemployment rates were climbing and inflation had peaked at an all-time high. To combat these issues, President Reagan introduced a number of economic policies, including tax cuts for large corporations and high-income earners. But did these policies actually stimulate economic growth or improve circumstances for Americans? Jonathan Smith investigates. Lesson by Jonathan Smith, directed by Gavin Edwards, Movult.
