Slave codes were a method of protecting the investment of white enslavers in the Colonies by restricting the lives of enslaved people in almost every imaginable way. The codes restricted enslaved people’s ability to move around, or engage in commerce that could make them financially independent - they restricted the opportunities that would allow them to live with even relative freedom. Today, we'll learn how Colonies put laws in place to restrict the movement and freedoms of enslaved people and free Black people.

In this episode of Crash Course: How to College, Erica helps us think about how to best choose the right school for us. There's a lot to think about, like: what kind of learner you are, what kind of environment you like, how to know if your school is looking out for your success, what kinds of support do different schools offer, and of course what do you want to study?

Crash Course: How to College is part of Study Hall, a partnership between ASU and Crash Course. Head over to our new Study Hall channel to check out our Fast Guide series which break down different college majors.

Today we’re going to talk about measures of central tendency - those are the numbers that tend to hang out in the middle of our data: the mean, the median, and mode. All of these numbers can be called “averages” and they’re the numbers we tend to see most often - whether it’s in politics when talking about polling or income equality to batting averages in baseball (and cricket) and Amazon reviews. Averages are everywhere so today we’re going to discuss how these measures differ, how their relationship with one another can tell us a lot about the underlying data, and how they are sometimes used to mislead.

What is globalization? Is globalization a good thing or not. Well, I have an answer that may not surprise you: It's complicated. This week, Jacob and Adriene will argue that globalization is, in aggregate, good. Free trade and globalization tend to provide an overall benefit, and raises average incomes across the globe. The downside is that it isn't good for every individual in the system. In some countries, manufacturing jobs move to places where labor costs are lower. And some countries that receive the influx of jobs aren't prepared to deal with it, from a regulatory standpoint. Anyway, Jacob and Adriene can explain the whole thing to you in 10 minutes.

Bridges... bridges, bridges, bridges. We talk a lot about bridges in physics. Why? Because there is A LOT of practical physics that can be learned from the planning and construction of them. In this episode of Crash Course Physics, Shini talks to us about a particular mistake made in engineering the Millennium Bridge which allows us to talk about simple harmonic motion.

This week Craig breaks out the crystal ball to try and figure out why our congresspeople do the things that they do. We’ll talk about the three motivating factors of congressional decisions - constituency, interest groups, and political parties - and we’ll break down how each of these factors motivates certain actions like casework, public opinion polls, and logrolling. Craig will even weigh in on which of these factors probably contributes most significantly to the actions and decisions of our congresspersons and he'll do it without even a touch of cynicism!

This week Craig Benzine discusses bureaucracies. Bureaucracies tend to be associated with unintelligible rules and time-wasting procedures, but they play an important, though controversial, role in governing. From the FDA to the EPA, these agencies were established to help the government manage and carry out laws much more efficiently - to bring rule-making and enforcement closer to the experts. But the federal bureaucracy (which is part of the executive branch) has a lot of power and sometimes acts like Congress in creating regulations and like the courts through administrative adjudications. It's all a bit problematic for that whole "separation of powers" thing. So we'll talk about that too, and the arguments for and against increased federal bureaucracy.

Just how small are nanomaterials? And what can we do with stuff that small? Today we’ll discuss some special properties of nanomaterials, how some can change at different sizes, and the difference between engineered nanomaterials and ones that occur naturally. We’ll also talk about some of the future research that’s needed on the use of nanomaterials.

Today, Craig Benzine is going to tell you about the Supreme Court's most important case, Marbury v. Madison, and how the court granted itself the power of judicial review. Judicial review is the power to examine and invalidate actions of the legislative and executive branches. It happens at both the state and federal court levels, but today we're going to focus primarily on the court at the top - the Supreme Court of the United States. Now it's important to remember that the court has granted itself these powers and they aren't found within the Constitution, but as with the executive and legislative branches, the courts rely heavily on implied powers to get stuff done.

Today, Craig is going to talk about political parties and their role in American politics. So, when most people think about political parties they associate them with the common ideologies of the voters and representatives within that party, but the goal of a party is NOT to influence policies. The role of political parties is much simpler: to win control of the government. So today, we’re going got talk about why we have political parties in the first place and then finish with the five functions they use in reaching that goal. It’s a lot to cover, so next week we’ll talk about what each political party stands for and how that has changed historically.

And now we return to blood vessels. In this episode, we start discussing what blood pressure is, how it can become "high", and what that means for our health. One of the more interesting points is that your body has ways of dealing with high blood pressure, but they're not ways we want our bodies to operate on a full-time basis. And why can't we butter our bacon? WHY!?!?!

This week Craig is going to give you a broad overview of elections in the United States. So as you may have noticed, there are kind of a lot of people in the U.S, and holding individual issues up to a public vote doesn't seem particularly plausible. So to deal with this complexity, we vote for people, not policies, that represent our best interests. But as you'll see, this process was not thoroughly addressed in the Constitution, so there have been a number of amendments and laws at the state level implemented to create the election system we all know and (maybe) love today.

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, what is geography? In our first episode of Crash Course Geography, we will endeavor to answer this seemingly simple question with the help of a similarly simple factoid: that the US imports more than 3 billion pounds of bananas from Guatemala each year. But as it turns out, beneath the kinds of factoids we usually associate with Geography are much grander stories that really are Geography. So let's go a little bananas as we explore the sordid history of the Chiquita banana.
