Despite the name, we don’t know where the so-called “hell pigs” belong in the mammalian family tree. They walked on hooves, like pigs do, but had longer legs, almost like deer. They had hunched backs, a bit like rhinos or bison. But as is often, if not always, the case, there is some evolutionary method to this anatomical madness.

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 Kurt Vonnegut's most famous novel, Slaughterhouse-Five. Vonnegut wrote the book in the Vietnam era, and it closely mirrors his personal experiences in World War II, as long as you throw out the time travel and aliens and porn stars and stuff. Slaughterhouse-Five tells the story of Billy Pilgrim, a World War II veteran who was a prisoner of war, and survived the Battle of the Bulge and the fire-bombing of Dresden, goes home after the war, and has trouble adapting to civilian life (this is the part that's like Vonnegut's own experience). Billy Pilgrim has flashbacks to the war that he interprets as being "unstuck in time." He believes he's been abducted by aliens, and pretty much loses it. You'll learn a little about Vonnegut's life, quite a bit about Dresden, and probably more than you'd like about barbershop quartets as a metaphor for post traumatic stress.

This week we explore final ethical theory in this unit: Aristotle’s virtue theory. Hank explains the Golden Mean, and how it exists as the midpoint between vices of excess and deficiency. We’ll also discuss moral exemplars, and introduce the concept of “eudaimonia.”

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
During World War II, there was also a painful period of Japanese relocation and internment throughout the country: https://www.commonlit.org/text....s/japanese-relocatio

In which John Green teaches you about the fall of the Roman Empire, which happened considerably later than you may have been told. While the Western Roman Empire fell to barbarians in 476 CE, the Byzantines in Constantinople continued the Eastern Empire nicely, calling themselves Romans for a further 1000 years. Find out what Justinian and the rest of the Byzantine emperors were up to over there, and how the Roman Empire dragged out its famous Decline well into medieval times. In addition to all this, you'll learn about ancient sports riots and hipster barbarians, too.
