While the focus has been on Western Europe so far, there has also been a lot going on in Eastern Europe, which we'll be looking at today. The Commonwealth of Poland-Lithuania, The Ottoman Empire, and Russia were all competing at the eastern end of the continent/landmass of Europe at during the 16th century. You'll learn about the various Ivans in Russia, and the Time of Trouble that followed them, and you'll learn about the Ottomans' expansion into Europe. You'll also learn how the great power you may not have heard of, Poland-Lithuania was right in the middle of all these events, from the rise of the False Dmitry to the Battle of Vienna.

In this episode of Crash Course Psychology, Hank walks us through the troubling world of Eating and Body Dysmorphic disorders. There's a lot going on here and, even though we still have a lot of dots to connect, a lot we can learn to help ourselves and each other.

In the world of ecology, the only constant is change - but change can be good. Today Hank explains ecological succession and how ecological communities change over time to become beautiful, biodiverse mosaics.

Chapters:
1. Primary Succession :1
2. Secondary Succession
3. Climax Community Model
4. Intermediate Disturbance Hypothesis :1

We’ve explored the origins of modern biology, the earth sciences, and even the sciences of outer space. Now it’s time to put these disciplines together. It's Ecology time!!!

Hank introduces us to ecology - the study of the rules of engagement for all of us earthlings - which seeks to explain why the world looks and acts the way it does. The world is crammed with things, both animate and not, that have been interacting with each other all the time, every day, since life on this planet began, and these interactions depend mostly on just two things... Learn what they are as Crash Course Biology takes its final voyage outside the body and into the entire world.

Chapters:
1) Ecological Hierarchy :2
a) Population
b) Community :1
c) Ecosystem
d) Biome :1
e) Biosphere

2) Key Ecological Factors
a) Temperature :1
b) Water

3) Biome Type :1

We're still leading up to World War II, but first we gotta talk about the rise of the dictators. Today we talk about the rise of militaristic dictatorships in Germany, the Soviet Union, Japan, and Spain, and the economic depression that set the stage for their rise.

We talk a lot about Keynesian economics on this show, pretty much because the real world currently runs on Keynesian principles. That said, there are some other economic ideas out there, and today we're going to talk about a few of them. So, if you've been aching to hear about socialism, communism, the Chicago School, or the Austrian School, this episode is for you.

In which Jacob Clifford and Adriene Hill teach you about Economic Systems and Macroeconomics. So, economics is basically about choices. We'll look at some of the broadest economic choices when we talk about the difference between planned economies and market economies. We'll get into communism, socialism, command economies, and capitalism. We'll look at how countries choose the kind of system they're going to use (spoiler alert: many end up with mixed economies). We'll also look into how individuals make economic choices.

This week we’ll see how economies can be broken down into the primary, secondary, and tertiary sectors. We’ll look at the three stages of economic revolution that brought us to the modern post-industrial era. We’ll also explore two types of economic models: capitalism and socialism.

We need to have a talk about your future. You're going to die. We all are. And it's probably going to be expensive. This week on CC Econ, Adriene is talking about the economics of death. Some of the expense is tied to the cost of end-of-life health care, but funerals are a big business, too.

How does education work? Where does the money come from? Who pays for it? Is going to college a good investment? Adriene and Jacob are talking today about the economics of education. Most countries require that their citizens get some education, and most countries pay for basic education, but the quality of education can vary widely. And in the US, post-secondary education can come with a lot of costs.

They say money can't buy happiness, but who are they? Can money buy happiness? The answer is: sort of. While money may not be able to buy true happiness, lack of money can cause very real misery. Today, we look at the economics of happiness, and talk about how much money it takes to be happy. And where you should live to maximize your income-to-happiness ratio.

Why is health care so expensive? Once again, there are a lot of factors in play. Jacob and Adriene look at the many reasons that health care in the US is so expensive, and what exactly we get for all that money. Spoiler alert: countries that spend less and get better results are not that uncommon.

Is Immigration good or bad? Immigration is a touchy subject in the United States. The 2016 election has been filled with debate about the subject, and both proponents and opponents have lots of reasons for their stance. But, this is a show about economics, and when it comes to the effects of immigration on economies, there is actually a lot of consensus. It turns out, immigration is economically beneficial.

Hank brings us to the next level of ecological study with ecosystem ecology, which looks at how energy, nutrients, and materials are getting shuffled around within an ecosystem (a collection of living and nonliving things interacting in a specific place), and which basically comes down to who is eating who.

Chapters:
1) Defining Ecosystems :1
2) Trophic Structure :1
a) Primary Producers
b) Primary Consumers
c) Secondary Consumers :1
d) Tertiary Consumers :2
e) Detrivores :1
3) Bioaccumulation

The Editor is yet another unsung hero in the filmmaking process. For a century of film history, Editors have taken raw footage and worked to transform it into a cohesive whole. Basically making one thing from many. But, how do they do it? In this episode of Crash Course Film Production, Lily Gladstone walks us through the editor's process and talks about some of the guidelines different editors use to make movies great!

Today we’ll explore the history of education as a social institution, with a specific focus on how the US organizes its educational system. We’ll look at education through the lenses of some sociological paradigms: structural functionalist approaches (including some of the manifest and latent functions associated with education), and a symbolic interactionist approach to education that shows us how self-fulfilling prophecies in educational settings contribute to differences in academic outcomes for students.

Chess, Number Munchers, The Oregon Trail! Today, we’re going to talk about gaming’s role in education. Now technically all games have an educational component, because games are defined by their rules and players have to learn those rules to participate. But of course there is a subset of games designed to teach players skills useful within but but also outside game worlds. And these kinds of games have actually been around for thousands of years! So today we’re going to focus a few educational game successes, talk about how they got there, and what they have done for us in the process.

Today we’re going to go a little meta and talk about how computer science can support learning with educational technology. We here at Crash Course are big fans of interactive in-class learning and hands-on experiences, but we also believe in the additive power of educational technology inside and outside the classroom from the Internet itself and Massive Open Online Courses, or MOOCs to AI driven intelligent tutoring systems and virtual reality.
