In the aftermath of a 8 – 20 solar mass star’s demise we find a weird little object known as a neutron star. Neutrons stars are incredibly dense, spin rapidly, and have very strong magnetic fields. Some of them we see as pulsars, flashing in brightness as they spin. Neutrons stars with the strongest magnetic fields are called magnetars, and are capable of colossal bursts of energy that can be detected over vast distances.

In which John Green teaches you about World War 2, as it was lived on the home front. You'll learn about how the war changed the country as a whole, and changed how Americans thought about their country. John talks about the government control of war production, and how the war probably helped to end the Great Depression. A broader implementation of the income tax, the growth of large corporations, and the development of the West Coast as a manufacturing center were also results of the war. The war positivelychanged the roles of women and African Americans, but it was pretty terrible for the Japanese Americans who were interred in camps. In short, World War II changed America's role in the world, changed American life at home, and eventually spawned the History Channel.

Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. At home in America, everyone joined in the war effort, with everyone contributing to American industry: https://www.commonlit.org/text....s/how-american-indus
But America had its fair share of shame, such as when the country turned away Jewish refugees on the St. Louis who would die in the Holocaust: https://www.commonlit.org/text....s/jewish-refugees-on

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.

In which John Green teaches you about globalization, a subject so epic, so, um, global, it requires two videos. In this video, John follows the surprisingly complex path of t-shirt as it criss-crosses the world before coming to rest on your doorstep, and eventually in your dresser. (Unless you're one of those people who never puts their laundry away and lives out of a laundry basket. If that's the case, shame on you.) Anyway, the story of the t-shirt and its manufacture in far-flung places like China, Guatemala, and India is a microcosm of what's going on in the global economy. Globalization is a bit of a mixed bag, and there have definitely been winners and losers along the way. In this episode John will talk about some of the benefits that have come along with it. Next week, he'll get into some of the less-positive side effects of globalization.

Also, you should turn on the captions.

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.
