The Harlem Renaissance produced many remarkable artists, writers, and thinkers. Today we'll talk about one of the most interesting minds of the time, Zora Neale Hurston. Hurston was an anthropologist by training and spent much of her career studying and documenting the lives of Black people in the southern US. She later went on to write several remarkable novels, including Their Eyes Were Watching God, which we discussed in Crash Course Literature. https://www.youtube.com/watch?v=4kF0U8kIMp4&t=1s

Hank veers away from human anatomy to teach us about the (mostly) single-celled organisms that make up two of the three taxonomic domains of life, and one of the four kingdoms: Archaea, Bacteria, and Protists. They are by far the most abundant organisms on Earth and are our oldest, oddest relatives.

In the late 19th and early 20th centuries, Black American Women were struggling with both racism and misogyny as they fought for their rights. Black Women formed clubs and organized to make sure civil and political rights were extended to ALL Black people, not just Black men. These clubs were grass-roots organizations of middle-class women who were often only one generation removed from slavery. Today we'll learn about the origins of these clubs and some of the notable women who drove this movement.

We've been talking about the unavoidables recently. Last time, we covered Death. This time, it's taxes. So, what are taxes? Why do we pay taxes? What is all that tax money used for? This week, Adriene is going to cover all that and more. We'll talk about types of taxes, progressive and regressive taxes, tax brackets, and we'll even get into a few historical scenarios where bad tax policy led to revolutions.

In which John Green teaches you about the beginning of the so-called Age of Discovery. You've probably heard of Christopher Columbus, who "discovered" America in 1492, but what about Vasco da Gama? How about Zheng He? Columbus gets a bad rap from many modern historians, but it turns out he was pretty important as far as the history of the world goes. That said, he wasn't the only pioneer plying the seas in the 1400s. In Portugal, Vasco da Gama was busy integrating Europe into the Indian Ocean Trade by sailing around Africa. Chinese admiral Zheng He was also traveling far and wide in the largest wooden ships ever built. Columbus, whether portrayed as a hero or a villain, is usually credited as the great sailor of the 15th century, but he definitely wasn't the only contender. What better way to settle this question than with a knock-down, drag-out, no holds barred, old-fashioned battle royal? We were going to make it a cage match, but welding is EXPENSIVE.

Today we're going to tell the story of a quiet revolution in the 1960s that shifted our entire understanding of how the Earth works. We currently believe that the Earth's broken outer shell rises from the mantle and folds back in - kind of like a dance of creative destruction and reconstruction - giving us our continents and oceans, mountains and valleys, volcanoes, and earthquakes. And it would take a group of scientists all over the world to get us this grand unifying theory of plate tectonics.

In which John Green teaches you about the Mughal Empire, which ruled large swaths of the Indian Sub-Continent from 1526 to (technically) 1857. While John teaches you about this long-lived Muslim empire, he'll also look at the idea of historical reputation and how we view people from history. Namely, he'll look at the reputations of Mughal emperors Akbar I and Aurangzeb. Traditionally, Akbar I is considered the emperor that made the Mughal Empire great, and Aurangzeb gets the blame for running the whole thing into the ground and setting it up for decline. Is that really how it was, though? It turns out, it's complicated.

In which John Green teaches you about the early days of the Civil Rights movement. By way of providing context for this, John also talks a bit about wider America in the 1950s. The 1950s are a deeply nostalgic period for many Americans, but there is more than a little idealizing going on here. The 1950s were a time of economic expansion, new technologies, and a growing middle class. America was becoming a suburban nation thanks to cookie-cutter housing developments like the Levittowns. While the white working-class saw their wages and status improve, the proverbial rising tide wasn't lifting all proverbial ships. A lot of people were excluded from the prosperity of the 1950s. Segregation in housing and education made for some serious inequality for African Americans. As a result, the Civil Rights movement was born. John will talk about the early careers of Martin Luther King, Thurgood Marshall, Rosa Parks, and even Earl Warren. He'll teach you about Brown v Board of Education, the lesser-known Mendez vs Westminster, the Montgomery Bus Boycott, and all kinds of other stuff.

Much like a cell membrane, our atmosphere forms a protective boundary between outer space and the biosphere that allows for all life to exist on Earth’s surface. Today, we’re going to talk about its composition and layers (the troposphere, stratosphere, mesosphere, and thermosphere), follow the path of a sunbeam of light as it travels through space and (potentially) reaches Earth’s surface, and discuss how the greenhouse effect can be both a good and bad thing!

#CrashCourse #Geography
In which John Green teaches you about the poetry of Langston Hughes. Langston Hughes was a poet and playwright in the first half of the 20th century, and he was involved in the Harlem Renaissance, which was a cultural movement among African Americans of the time that produced all kinds of great works in literature, poetry, painting, sculpture, music, and other areas. The Harlem Renaissance mainly happened in Harlem, the traditionally black neighborhood in upper Manhattan in New York City. Langston Hughes was primarily known as a poet, but he was involved deeply in the movement itself as well. John will teach you a bit about Hughes's background, and he'll examine a few of his best-known poems.

Population ecology is the study of groups within a species that interact mostly with each other, and it examines how they live together in one geographic area to understand why these populations are different in one time and place than they are in another. How is that in any way useful to anyone ever? Hank uses the example of the West Nile virus outbreak in Texas to show you in this episode of Crash Course: Ecology.

Today we’re going to talk about climate change which is when there is a change in the average weather patterns in a region over a long period of time - these changes can be natural or human-caused. We’ll discuss the main driving forces of climate change in the past and show you how what’s happening now is unlike anything in the past. Global warming, or when there is an increase in the average surface temperature of the planet, has been well-documented since the Industrial Revolution, and scientists have concluded that there is a 95% probability that human activities like burning fossil fuels, industrialization, modern agriculture, and deforestation have caused most of this most recent warming. And while individual actions do matter in helping to curb the disastrous implications of a warming planet, it’s also up to us to hold corporations and governments responsible for the policies and the large-scale emissions that play a disproportionate role in impacting our atmosphere and climate.

Just like many great duos throughout history, Bulgaria and Germany have a fascinating (though uneven) relationship. In today’s episode, we’re going to take a closer look at the impact of politics on economies as we trace this history of Bulgaria and Germany following World War II, and examine the ways capitalism, and communism, impacted their economic strength today.

Today on Crash Course Economics, Adriene and Jacob talk about the 2008 financial crisis and the US Goverment's response to the troubles. So, all this starts with home mortgages, and the use of mortgages as an investment instrument. For years, it seemed like the US housing market would go up and up. Like a bubble or something. It turns out it was a bubble. But not the good kind. And the government response was...interesting. Anyway, why are you reading this? Watch the video!

We’ve talked about how broad a concept “the media” really is – and given that, it can be hard to keep track of all the different forces that constitute “the media.” It can be tough, but it’s not impossible. Today we’re talking about how all those big players fit together and why all those mergers and acquisitions matter to being a media literate citizen.
