Today we’re going to talk about numeracy - that is understanding numbers. From really really big numbers to really small numbers, it's difficult to comprehend information at this scale, but these are often the types of numbers we see most in statistics. So understanding how these numbers work, how to best visualize them, and how they affect our world can help us become better decision makers - from deciding if we should really worry about Ebola to helping improve fighter jets during World War II!

Episode Notes:

Tim Urban’s wonderful post about visualizing large numbers:

We’re continuing our exploration of conflict theories with W.E.B. Dubois, who is one of the founders of sociological thought more broadly and the founder of race-conflict theory. We’ll discuss shifting ideas about race, Dubois’ idea of ‘double-consciousness’, and the modern day field of racial identity. We’ll explore the idea racial formation and discuss Dubois’ survey of African Americans in Philadelphia to look at how economic, political, and social structures affect how we perceive different races – and vice versa. We’ll also discuss the activist side of Dubois’ life as co-founder of the NAACP and editor of the Crisis, and how modern day sociologists study racial politics and racial resistance.

How do different societies establish a social hierarchy? Today we’re starting our unit on social stratification, starting with four basic principles of a sociological understanding of stratification. We’ll explain open and closed systems of stratification and explore examples of different kinds of stratification systems, including caste systems and class systems.

This week, John i s talking about one of his least favorite novels, The Lord of the Flies by William Golding. Lord of the Flies is a novel of ideas, and John doesn't agree with the central idea of the novel, which diminished his enjoyment of the book. The central idea of the book is that everyone has evil in their hearts. Which we don't necessarily agree with. That said, it's a good read, and worth reading.

Today we’re going to talk about good and bad surveys. From user feedback surveys, telephone polls, and those questionnaires at your doctors office, surveys are everywhere, but with their ease to create and distribute, they're also susceptible to bias and error. So today we’re going to talk about how to identify good and bad survey questions, and how groups (or samples) are selected to represent the entire population since it's often just not feasible to ask everyone.

Learn about hadiths, Abu Bakr, and whether the Umma has anything to do with Uma Thurman (spoiler alert: it doesn't). Also, learn a little about the split between Sunni and Shia Muslims, and how to tell if this year's Ramadan is going to be difficult for your Muslim friends. Let's try to keep the flame wars out of this reasoned discussion.

You're being watched. That sounded more sinister than I intended, but online, it's true. Facebook, Instagram, Amazon, Netflix... the list goes on and on. They're watching what you do, what you shop for, what you watch... all of it. And have you actually read the Terms of Service? In this episode of Crash Course Media Literacy, Jay talks about how Online Advertising works and why companies want to know everything you're looking at.

How much should you get paid for your job? Well, that depends on a lot of factors. Your skill set, the demand for the skills you have, and what other people are getting paid around you all factor in. In a lot of ways, labor markets work on supply and demand, just like many of the markets we talk about in Crash Course Econ. But, again, there aren't a lot of pure, true markets in the world. There are all kinds of oddities and regulations that change the way labor markets work. One common (and kind of controversial one) is the minimum wage. The minimum wage has potential upsides and downsides, and we'll take a look at the various arguments for an against it.

Today we’re going to talk about confidence intervals. Confidence intervals allow us to quantify our uncertainty, by allowing us to define a range of values for our predictions and assigning a likelihood that something falls within that range. And confidence intervals come up a lot like when you get delivery windows for packages, during elections when pollsters cite margin of errors, and we use them instinctively in everyday decisions. But confidence intervals also demonstrate the tradeoff of accuracy for precision - the greater our confidence, usually the less useful our range.

In which John Green teaches you about a time of relative tumult in the United States, the 1960s. America was changing rapidly in the 1960s, and rights movements were at the forefront of those changes. Civil Rights were dominant, but the 60s also saw growth in the Women's Movement, the LGBT rights movement, the Latino rights movement, and the American Indian movement. Also, Americans began to pay a bit more attention to the environment. All this change happened against the backdrop of the Cold War and the Rise of Conservatism. It was just wild. John will teach you about sit-ins, Freedom Rides, The March on Washington, MLK, JFK, LBJ, and NOW. Man, that is a lot of initialisms. And one acronym.

Today we're going to introduce one of the most flexible statistical tools - the General Linear Model (or GLM). GLMs allow us to create many different models to help describe the world - you see them a lot in science, economics, and politics. Today we're going to build a hypothetical model to look at the relationship between likes and comments on a trending YouTube video using the Regression Model. We'll be introducing other popular models over the next few episodes.

We’ve talked about how broad a concept “the media” really is – and given that, it can be hard to keep track of all the different forces that constitute “the media.” It can be tough, but it’s not impossible. Today we’re talking about how all those big players fit together and why all those mergers and acquisitions matter to being a media literate citizen.

As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they're really fascinating and a crucial part of physics. In this episode of Crash Course Physics, Shini chats about capacitors, conductors, electric field lines, and how objects with net charge generate electric fields.

As the Roman Empire fell, so did the theater. If there's anyone who hates theater and actors more than Romans, it's early Christians. As Christianity ascended in the west, theater declined. But, fear not. This isn't the end of the series. Theater would be back, and in the best subversive theater-y fashion, it would return via the Catholic mass!

What is culture? How do we define it and how does it change? We’ll explore different categories of culture, like low culture, high culture, and sub-cultures. We'll also revisit our founding theories to consider both a structural functionalist and a conflict theory perspective on what cultures mean for society.

The way light behaves can seem very counter intuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense! In this episode of Crash Course Physics, Shini shows us how we know that light exists as a wave and why that's really cool!
