Our first of two episodes about Gabriel Garcia Marquez's novel, 100 Years of Solitude. This week, we're looking at the Buendia family, and their many generations of people with the same names. We'll also look at the fascinating way the author thinks about time, and how time is represented in the book. Later, we'll get into the genre that Garcia Marquez worked in, which is called magical realism. Years later, we will have talked about all of this before.

In which we continue our exhaustive look at One Hundred Years of Solitude by Gabriel Garcia Marquez.

The 17th Century in Europe was pretty rough in a lot of ways. The Thirty Years War involved a lot of countries, and a lot of battles, and it was terrible for everyone involved, as wars have aa historical tendency to be. At the same time, disease and hunger were common, thanks in part to the climate change of the Little Ice Age. Get ready for some misery.

European powers had a lot of wars in the 18th century, and they weren't confined to Europe. Conflict raged across the globe, in what might be called a World War...but we don't call it that, because we already have a couple of those coming up in the 20th century. Some call it the Great War for Empire, and some call it a bunch of separate wars, but in any case, all this conflict was important, and you're going to learn all about it right now.

In which John Green returns for a dystopian new season of Crash Course Literature! We're starting with George Orwell's classic look at the totalitarian state that could be in post-war England. Winston Smith is under the eye of Big Brother, and making us think about surveillance, the role of government, and how language can play a huge part in repressive regimes.

In which John Green teaches you about various reform movements in the 19th century United States. From Utopian societies to the Second Great Awakening to the Abolition movement, American society was undergoing great changes in the first half of the 19th century. Attempts at idealized societies popped up (and universally failed) at Utopia, OH, New Harmony, IN, Modern Times, NY, and many other places around the country. These utopians had a problem with mainstream society, and their answer was to withdraw into their own little worlds. Others didn't like the society they saw and decided to try to change it. Relatively new Protestant denominations like the Methodists and Baptists reached out to "the unchurched" during the Second Great Awakening, and membership in evangelical sects of Christianity rose quickly. At the same time, Abolitionist societies were trying to free the slaves. Americans of the 19th century had looked at the world they were living in and decided to change it.

In which John introduces you to quite a lot of Chinese history by discussing the complicated relationship between the Confucian scholars who wrote Chinese history and the emperors (and empress) who made it. Included is a brief introduction to all the dynasties in Chinese history and an introduction to Confucius and the Confucian emphasis on filial piety, the role the mandate of heaven played in organizing China, and how China became the first modern state.

The 21st century brought a whole new host of challenges to the world, and Europe was no exception. In this video you'll learn about how an increasingly connected and complex world led to some pretty deep rifts in countries across the continent. We'll learn about financial crises that rippled across the world. We'll learn about wars and resultant migrations that sowed discord in many European nations. Increasing polarization and populism played out in movements like Brexit in the UK. While we don't know what the future holds, an understanding of the roots of conflict can help create a roadmap for the future.

Today we’re going to discuss how 3D graphics are created and then rendered for a 2D screen. From polygon count and meshes, to lighting and texturing, there are a lot of considerations in building the 3D objects we see in our movies and video games, but then displaying these 3D objects of a 2D surface adds an additional number of challenges. So we’ll talk about some of the reasons you see occasional glitches in your video games as well as the reason a dedicated graphics processing unit, or GPU, was needed to meet the increasing demand for more and more complex graphics.

The organic molecules that make up life on Earth are more than just the 2-D structures we’ve been drawing so far. Molecules have 3-D shapes that help us understand what they can do. In this episode of Crash Course Organic Chemistry, we’ll learn how orbital hybridization and valence bond theory can help us explain 3D molecular structures and about constitutional and geometric isomers.

Hank gives the rundown on the top five ways humans are negatively impacting the environment and having detrimental effects on the valuable ecosystem services which a healthy biosphere provides.

We've talked about AC Circuits, but now it's time to delve into the world of AC Circuits (or alternating currents). We’ve talked about how they change voltage, which helps transmit electricity over long distances, but there’s so much more to the physics of AC circuitry.

As we mentioned last episode, one of the best test spaces for building new AI systems are games. This is because games provide a great framework for an AI to learn an objective and slowly improve. In recent years, AI has made huge strides in games from beating Jeopardy! champions to crushing a five-person team in DOTA 2. Today, we’re going to walk you through creating a Tic Tac Toe bot that uses the minimax algorithm to become undefeatable and we’ll talk about evolutionary neural networks like in SethBling’s MarI/O project. Next week we’ll create our very own game and create an AI to master it!

Today we're going to continue our discussion of statistical models by showing how we can find if there are differences between multiple groups using a collection of models called ANOVA. ANOVA, which stands for Analysis of Variance is similar to regression (which we discussed in episode 32), but allows us to compare three or more groups for statistical significance.

Do you think a red minivan would be more expensive than a beige one? Now what if the car was something sportier like a corvette? Last week we introduced the ANOVA model which allows us to compare measurements of more than two groups, and today we’re going to show you how it can be applied to look at data that belong to multiple groups that overlap and interact. Most things after all can be grouped in many different ways - like a car has a make, model, and color - so if we wanted to try to predict the price of a car, it’d be especially helpful to know how those different variables interact with one another.

So far, the rulers of Europe have been working to consolidate their power and expand their kingdoms, and this is it. The moment they've been working toward: Absolute Monarchy. We're going to learn about how kings and queens became absolute rulers in Europe, and where better to start than with Louis XIV of France, who is really the model for absolute rule.

Last week, Hank talked about how stuff mixes together in solutions. Today, and for the next few weeks, he will talk about the actual reactions happening in those solutions - atoms reorganizing themselves to create whole new substances in the processes that make our world the one we know and love. This week, we focus on acids and bases and their proton-exchanging ways.

Acids and Bases are Complicated

Acidity is a tricky concept, and it’s not always like how we see it in the movies. As organic chemists, we need to know how to predict the strength of weak acids and bases. In this episode of Crash Course Organic Chemistry, we’ll learn four key factors that we can use to predict relative acidity. This important tool will help us us to predict the products of chemical reactions.

So now that we’ve built and programmed our very own CPU, we’re going to take a step back and look at how CPU speeds have rapidly increased from just a few cycles per second to gigahertz! Some of that improvement, of course, has come from faster and more efficient transistors, but a number hardware designs have been implemented to boost performance. And you’ve probably heard or read about a lot of these - they’re the buzz words attached to just about every new CPU release - terms like instruction pipelining, cache, FLOPS, superscalar, branch prediction, multi-core processors, and even super computers! These designs are pretty complicated, but the fundamental concepts behind them are not. So bear with us as we introduce a lot of new terminology including what might just be the best computer science term of all time: the dirty bit. Let us explain.
