Ever feel like there's an international team of bad guys changing all of the easily remembered chemical names and turning them into test-failing, number-infused, pain-in-the-neck names? Well... you're not wrong. IUPAC exists, but try to keep in mind that they're doing it for the greater good. In this episode, Hank talks about IUPAC, prefixes, suffixes, ranking, numbers for carbon chains, and cis or trans double bonds.

This week Craig Benzine takes a first look at the judicial branch. It's pretty easy to forget that the courts, and the laws that come out of them, affect our lives on a daily basis. But how exactly these decisions are made and where each law's jurisdiction starts and ends can get pretty complicated. So complicated in fact that you may want to smash something. But don't worry, Craig will clear the way.

Waves are cool. The more we learn about waves, the more we learn about a lot of things in physics. Everything from earthquakes to music! Ropes can tell us a lot about how traveling waves work so, in this episode of Crash Course Physics, Shini uses ropes to talk about how waves carry energy and how different kinds of waves transmit energy differently.

Over the next few episodes we’re going to talk about the history of video games. Today, we’re going to start with the first re-programmable computers in the 1940’s. Now, these computers were serious tools. They were for codebreaking and calculating artillery tables during World War II - but like most tools we human use, we eventually looked for ways to make them playthings. And over the next three decades the advances of computer technology and the tentative curiosity of many engineers and programmers would inspire a new culture and eventually the first true coin-operated video game in 1971.

This week Craig looks at the expressed powers of the President of the United States - that is the ones you can find in the Constitution. From appointing judges and granting pardons, to vetoing laws and acting as the nation’s chief diplomat on foreign policy, the Commander in Chief is a pretty powerful person, but actually not as powerful as you might think. The Constitution also limits presidential powers to maintain balance among the three branches of government. Next week we'll talk about the President's powers NOT mentioned in the Constitution - implied powers.

So we ended last episode at the start of the 20th century with special purpose computing devices such as Herman Hollerith’s tabulating machines. But as the scale of human civilization continued to grow as did the demand for more sophisticated and powerful devices. Soon these cabinet-sized electro-mechanical computers would grow into room-sized behemoths that were prone to errors. But is was these computers that would help usher in a new era of computation - electronic computing.

Last week we introduced the idea of socialization and today we’re talking a little more about how it works, including an introduction to five main types of socialization. We’ll explore anticipatory socialization from your family, the “hidden curriculum” in schools, peer groups, the role of media in socialization, and we’ll discuss total institutions and how they can act as a form of re-socialization.

In which Craig Benzine tells you how we keep bureaucracy in check. So we've spent the last few episodes telling you all about what bureaucracies are and why they are formed. And throughout we've hinted about this ever-expanding power within the executive branch. So today, we're going to finish our discussion of bureaucracy by looking at methods the other branches of government use to manage this power. From watch-dog organizations to reporting requirements there has been quite a bit of legislation passed aimed at taming the bureaucracy.

So today Craig is going to talk about where our political opinions come from. Of course, most people’s politics are grounded in their ideologies, but there are also other external influences such as the government itself, interest groups, and the media. So we're going to talk about how these influencers factor into the overall public opinion and how their roles have changed over time. Now this stuff may seem like common sense, but it’s important to know where our opinions come from, especially when you consider how quickly the media landscape is changing.

In which Craig Benzine breaks down the different types of bureaucracies. I mean sure, they’re all part of the executive branch, but some work more directly with the President than others. Some bureaucracies exist solely to independently regulate industry whereas others are expected to operate like corporations and make a profit. And on top of all that, some of these agencies have sub-agencies! It can all get pretty complicated, so we’ll try to discuss some of the most significant agencies out there and the ones you hear a lot about on the news. We’ll talk about how they seem to have steadily gained more and more power, and of course, we’ll talk about what all the agencies are for in the first place!

In which Craig Benzine teaches you about delegation and informal powers. What are all these federal agencies about? Well, the President has a lot of stuff to do as the chief executive, and as much as Americans like to talk about personal responsibility, the President can't really do all this stuff alone. Because it's a huge job! Same deal with Congress. So, they delegate authority. This is where all the government agencies and stuff come from. Congress creates them to actually get around to enforcing laws. You'll learn about stuff like OSHA, the FDA, and maybe even the FCC. Although you hear an occasional complaint about bureaucracies and such, the business of government wouldn't get done without agencies and delegation.

Finally, after what seems like eons and eons, the end is nigh. We're talking not only about the end of Crash Course Big History but also the end of everything. The end of humanity and the end of the universe. John and Hank Green will teach you about what the future holds for humanity and the universe. Spoiler alert: in the long, long, long, long, long, long term, it doesn't look good. In the short term though, it's not too bad. But don't lose hope, there is an upside. You'll have to watch the video to find out.

In which John Green kicks off the Crash Course Literature mini-series with a reasonable set of questions. Why do we read? What's the point of reading critically. John will argue that reading is about effectively communicating with other people. Unlike direct communication though, the writer has to communicate with a stranger, through time and space, with only "dry dead words on a page." So how's that going to work? Find out with Crash Course Literature! Also, readers are empowered during the open letter, so that's pretty cool.

Today, FINALLY, Craig is going to talk about Free Speech! Now, free speech is so important because it not only allows you to critique the government, but it also protects you from the government. But it's essential to remember that not ALL speech is protected equally under the First Amendment, and just because you have a right to free speech doesn't mean your employer, for instance, can't fire you for something you say (unless your work for the government and then things get a bit more complicated). So we'll take a look at a couple significant Supreme Court cases that have gotten us to our current definition of free speech, and we'll also discuss some of the more controversial aspects of free speech - like hate speech.
