Jupiter is the biggest planet in our solar system. The gas giant is NOT a failed star, but a really successful planet! It has a dynamic atmosphere with belts and zones, as well as an enormous red spot that’s actually a persistent hurricane. Jupiter is still warm from its formation, and has an interior that’s mostly metallic hydrogen, and it may not even have a core.

Hank explores different ways of understanding identity – including the Indiscernibility of Identicals, and essential and accidental properties. In what ways does affect identity? In what ways does it not? What does it mean for a thing to persist over time?

The majority of the universe is made up of a currently mysterious entity that pervades space: dark energy. We don’t know exactly what it is, but we do know that dark energy accelerates the expansion of space. We think this means the Universe will expand forever, even as our view of it shrinks while space expands faster all the time.

So, during times of inflation or deflation, why doesn't the government just set prices? It sounds reasonable, but price ceilings or floors just don't work. Adriene and Jacob explain why. Subsidies, however, are a little different, and sometimes they even work. We'll also explain that. Today you'll learn about stuff like price controls, deadweight loss, subsidies, and efficiency.

In which John Green teaches you how Russia evolved from a loose amalgamation of medieval principalities known as the Kievan Rus into the thriving democracy we know today. As you can imagine, there were a few bumps along the road. It turns out, our old friends the Mongols had quite a lot to do with unifying Russia. In yet another example of how surprisingly organized nomadic raiders can be, the Mongols brought the Kievan Rus together under a single leadership, and concentrated power in Moscow. This set the stage for the various Ivans (the Great and the Terrible) to throw off the yoke and form a pan-Russian nation ruled by an autocratic leader. More than 500 years later, we still have autocratic leadership in Russia. All this, plus a rundown of some of our favorite atrocities of Ivan the Terrible, and a visit from Putin!

In which Craig Benzine teaches you about the US Governments Separation of powers and the system of checks and balances. In theory, the Legislative Branch, the Executive Branch, and the Judicial Brach are designed to keep each other in check, and to keep any branch from becoming too powerful. In reality, the system was designed to keep the president from becoming some kind of autocrat. For the most part, it has worked. Craig will call in the clones to explain which powers belong to which branches, and to reveal some secret perks that the Supreme Court justices enjoy.

We’re picking up where we left off last time, exploring the “ethics of care” and how it applies to extreme poverty. Are we responding to global poverty in a moral way? Philosophers like Peter Singer argue that we have an obligation to prevent harm caused by poverty, whereas Garrett Hardin offers a “lifeboat analogy” to explain our obligations to focus on caring for our own.

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 a of West Nile virus outbreak in Texas to show you in this episode of Crash Course: Ecology.

READ THIS: THERE ARE TWO MORE VIDEOS IN THE WORLD HISTORY SERIES. You should also turn on the captions. You'll like them.
In which John Green teaches you about the post-World War II breakup of most of the European empires. As you'll remember from previous installments of Crash Course, Europeans spent several centuries sailing around the world creating empires, despite the fact that most of the places they conquered were perfectly happy to carry on alone. After World War II, most of these empires collapsed. This is the story of those collapses. In most places, the end of empire was not orderly, and violence often ensued. While India was a (sort of) shining example of non-violent change, in places like The Congo, Egypt, Rwanda, Vietnam, Cambodia, and Laos, things didn't go smoothly at all. John brings you all this, plus pictures of Sea Monkeys. Sadly, they don't look anything like those awesome commercials in the comic books.

To explore this idea further, this week Shini sits down with us to discuss centripetal force, centrifugal force, and a few other bits of physics to help us understand Uniform Circular motion.

Today we are moving on from the existence of God to look at the philosophical debate surrounding the traditional divine attributes - omnipotence, omniscience, omnitemporality, and omnibenevolence. We are exploring the puzzles that these attributes create as well as some possible solutions to those puzzles, from Aquinas’ ideas of analogical predication, to the work of Eleanor Stump.

So, if economics is about choices and how we use our resources, econ probably has a lot to say about the environment, right? Right! In simple terms, pollution is just a market failure. The market is producing more pollution than society wants. This week, Adriene and Jacob focus on the environment, and how economics can be used to control and reduce pollution and emissions. You'll learn about supply and demand, incentives, and how government intervention influences the environment.

In which John Green teaches you about water! So, we talk about resources a lot on Crash Course, and today is no exception. It turns out people can't live without water, which means it's absolutely necessary for civilization. Today John talks about water in the context of classical civilizations, but not like Greece or Rome or something. We're talking about the Maya civilization in Central America, and the Khmer civilization in what is now Cambodia. So this is an awesome video, OK?

So who was this smarty pants? In this episode Hank talks to us about Socrates and his two important students, Plato and Aristotle.
