In which John Green teaches you about the Industrial Economy that arose in the United States after the Civil War. You know how when you're studying history, and you're reading along and everything seems safely in the past, and then BOOM you think, "Man, this suddenly seems very modern." For me, that moment in US History is the post-Reconstruction expansion of industrialism in America. After the Civil War, many of the changes in technology and ideas gave rise to this new industrialism. You'll learn about the rise of Captains of Industry (or Robber Barons) like Cornelius Vanderbilt, Andrew Carnegie, John D Rockefeller, and JP Morgan. You'll learn about trusts, combinations, and how the government responded to these new business practices. All this, plus John will cover how workers reacted to the changes in society and the early days of the labor movement. You'll learn about the Knights of Labor and Terence Powderly, as well as Samuel Gompers and the AFL.

You probably know some of the signs of industrialization in the nineteenth century: Trains connected cities, symbolizing progress. But they also brought about the destruction of rural lands, divisions between social classes, and rapid urbanization. But there's a whole lot more to talk about in this episode of History of Science!

In which Adriene and Jacob teach you about how and why prices rise. Sometimes prices rise as a result of inflation, which is a pretty normal thing for economies to do. We'll talk about how across the board prices rise over time, and how economists track inflation. Bubbles are a pretty normal thing for humans to do. One item, like tulips or beanie babies or houses or tech startups experience a rapid rise in prices. This is often accompanied by speculation, a bunch of outrageous profits, and then a nasty crash when the bubble bursts. People get excited about rising prices, and next thing you know, people are trading their life savings for a tulip bulb.

We’ve mentioned already that there’s a lot of money in media and a huge chunk of that money is spent on trying to get you to do something – buy something, vote a certain way, change a behavior. How does advertising work? And what’s the difference between advertising, public relations, and propaganda? We’re going to talk about all that and more today.

Today we’re going to talk about controllers. Controllers are incredibly important in the gaming experience because they are how we communicate actions within a game and often play a significant role in why we like or dislike certain games. And over the years they have seen some huge improvements mostly brought on by the creation of more complex and immersive video games. Controller design is so important in fact that some of the largest game console manufacturers spend hundreds of millions of dollars each cycle trying to update and refine their designs. But interestingly, the same can’t quite be said for one of the biggest gaming platforms right now - so we’ll talk about that too.

Today we’re going to take our first baby steps from hardware into software! Using that CPU we built last episode we’re going to run some instructions and walk you through how a program operates on the machine level. We'll show you how different programs can be used to perform different tasks, and how software can unlock new capabilities that aren't built into the hardware. This episode, like the last is pretty complicated, but don’t worry - as we move forward into programming the idea of opcodes, addresses, and registers at this machine level will be abstracted away like many of the concepts in this series.

Continuing with last week's calculus introduction, Shini leads us through how integrals can help us figure out things like distance when we have several other essential bits of information. Say, for instance, you wanted to know how far your window was off the ground. You can figure that out by using integrals, a tennis ball, and a stopwatch! It's all here in this episode of Crash Course Physics!
So you may have heard of Moore's Law and while it isn't …
So you may have heard of Moore's Law and while it isn't truly a law it has pretty closely estimated a trend we've seen in the advancement of computing technologies. Moore's Law states that we'll see approximately a 2x increase in transistors in the same space every two years, and while this may not be true for much longer, it has dictated the advancements we've seen since the introduction of transistors in the mid 1950s. So today we're going to talk about those improvements in hardware that made this possible - starting with the third generation of computing and integrated circuits (or ICs) and printed circuit boards (or PCBs). But as these technologies advanced a newer manufacturing process would bring us to the nanoscale manufacturing we have today - photolithography.

So last week we talked about what special interest groups are and how they influence the political system, and today we’re going to focus on why we even have them in the first place. As to avoid getting too cynical, we’re going to focus on five benefits of special interest groups and look at how these factor weigh in a group’s formation and size. We’ll also talk about lobbyists, recent congressional action to limit their influence, and finish with a discussion of both insider and outsider strategies that interest groups use to influence policy.

Today, Craig is going to talk about something you fans out there have been demanding for months - money in politics. Specifically, we're going to talk about special interest groups and their role in the U.S. political system. Special interest groups are groups of individuals that make policy-related appeals to government - like the NRA, AARP, or the U.S. Chamber of Commerce. It's all pretty controversial, as money plays an important role in the policies and people these groups influence, so we'll bring in the clones to argue for and against them.

Climate change is being addressed by individuals, activist groups, and large corporations, but it’s going to take getting entire nations on board if we want to really meet our climate goals. In this episode of Crash Course Climate and Energy, we’ll learn about the alphabet soup that is global climate organization and take a look at some successful – and not-so-successful – international climate policies.

This week, Stan Muller teaches you how intellectual property law functions internationally. Like, between countries. Well, guess what. There's kind of no such thing as international law. But we can talk about treaties. There is a bevy of international treaties that regulate how countries deal with each others' IP. The upside is that this cooperation tends to foster international trade. The downside is that these treaties tend to stifle creativity by making it harder to shorten copyright terms. You win some, you lose some.

Today, we're going to talk about how the Internet works. Specifically, how that stream of characters you punch into your browser's address bar, like "youtube.com", return this very website. Just to clarify we're talking in a broader sense about that massive network of networks connecting millions of computers together, not just the World Wide Web, which is a portion of the Internet, and our topic for next week. Today, we're going to focus on how data is passed back and forth - how a domain name is registered by the Domain Name System, and of course how the data requested or sent gets to the right person in little packets following standard Internet Protocol, or IP. We'll also discuss two different approaches to transferring this data: Transmission Control Protocol, or TCP, when we need to be certain no information is lost, and User Datagram Protocol, or UDP, for those time sensitive applications - because nobody wants an email with missing text, but they also don't want to get lag-fragged in their favorite first person shooter.

We’ve talked a lot about advances in biotech. But none of those could have happened without advances in computing. It’s time to get back to data and explore the unlikely birth, strange life, and potential futures of the Internet. In this episode of Crash Course History of Science, Hank sits down to talk about how computers have changed, where they're going, and how the internet fits into all of this.
