Circulatory & Respiratory Systems – CrashCourse Biology #27

Hank takes us on a trip around the body – we follow the circulatory and respiratory systems as they deliver oxygen and remove carbon dioxide from cells, and help make it possible for our bodies to function.

The Amazing Life and Strange Death of Captain Cook: Crash Course World History #27

In which John Green teaches you about the life and death of one of history’s great explorers, Captain James Cook of the British Navy. He charted large swaths of the Pacific ocean, laid claim to Australia and New Zealand, and died a bizarre death in the Sandwich Islands, which are now called the Hawaiian Islands. Exactly how and why Captain Cook was killed in Hawaii is a long-running historical debate. John presents two interpretations of the event, and talks about what the differing interpretations say about history. It turns out how the story is told depends on who is doing the storytelling, and people from different backgrounds can interpret events in very different ways. Also, there is a celebration and a moustache involved in this episode, so you definitely don’t want to miss it.

The Nervous System – CrashCourse Biology #26

Hank begins a series of videos on organ systems with a look at the nervous system and all of the things that it is responsible for in the body.

The Seven Years War: Crash Course World History #26

The totally beautiful Crash Course poster by Thought Bubble is now available for preorder! http://dftba.com/artist/46/CrashCourse Also, the Mongols T-shirt is back in stock.

In which John teaches you about the Seven Years War, which may have lasted nine years. Or as many as 23. It was a very confusing was. The Seven Years War was a global war, fought on five continents, which is kind of a lot. John focuses on the war as it happened in the Americas, Asia, and Africa. the “great” European powers were the primary combatants, but they fought just about everywhere. Of course, this being a history course, the outcomes of this war still resonate in our lives today. The Seven Years war determined the direction of the British Empire, and led pretty directly to the subject of Episode 28, the American Revolution.

The Spanish Empire, Silver, & Runaway Inflation: Crash Course World History #25

Crash Course Poster available for pre-order now: http://dftba.com/crashcourseposter This is the first in a series of three Crash Course World History posters featuring many of the Thought Bubble characters from the episodes. When the series is complete, they’ll all fit together to make one giant, beautiful poster. Hooray!

In which John Green explores how Spain went from being a middling European power to one of the most powerful empires on Earth, thanks to their plunder of the New World in the 16th and 17th centuries. Learn how Spain managed to destroy the two biggest pre-Columbian civilizations, mine a mountain made of silver, mishandle their economy, and lose it all by the mid-1700s. Come along for the roller coaster ride with Charles I (he was also Charles V), Philip II, Atahualpa, Moctezuma, Hernán Cortés, and Francisco Pizarro as Spain rises and falls, and takes two empires and China down with them.

Chordates – CrashCourse Biology #24

Hank introduces us to ourselves by taking us on a journey through the fascinatingly diverse phyla known as chordata. And the next time someone asks you who you are, you can give them the facts: you’re a mammalian amniotic tetrapodal sarcopterygian osteichthyen gnathostomal vertebrate cranial chordate.

The Atlantic Slave Trade: Crash Course World History #24

In which John Green teaches you about one of the least funny subjects in history: slavery. John investigates when and where slavery originated, how it changed over the centuries, and how Europeans and colonists in the Americas arrived at the idea that people could own other people based on skin color.

Slavery has existed as long as humans have had civilization, but the Atlantic Slave Trade was the height, or depth, of dehumanizing, brutal, chattel slavery. American slavery ended less than 150 years ago. In some parts of the world, it is still going on. So how do we reconcile that with modern life? In a desperate attempt at comic relief, Boba Fett makes an appearance.
