We’re picking up where we left off last time, exploring the “ethics of care” and how it applies to extreme poverty. Are we responding to global poverty in a moral way? Philosophers like Peter Singer argue that we have an obligation to prevent harm caused by poverty, whereas Garrett Hardin offers a “lifeboat analogy” to explain our obligations to focus on caring for our own.

Over the millennia, every region on Earth has developed its own successful agricultural ecosystem from flat fields of grain and mountainside rice terraces to coastal fish farms and goat herding. Today, we’re going to break down agricultural systems into three scales: subsistence, small-scale, and industrial agriculture. And we’ll take a look at how a place's history plays a huge role in the system we see today as we follow the story of agriculture in the Philippines.

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.

Why are some countries rich? Why are some countries poor? In the end it comes down to Productivity. This week on Crash Course Econ, Adriene and Jacob investigate just why some economies are more productive than others, and what happens when an economy is mor productive. We'll look at how things like per capita GDP translate to the lifestyle of normal people. And, there's a mystery.

Today Hank begins to teach you about Philosophy by discussing the historical origins of philosophy in ancient Greece, and its three main divisions: metaphysics, epistemology, and value theory. He will also introduce logic, and how you’re going to use it to understand and critically evaluate a whole host of different worldviews throughout this course. And also, hopefully, the rest of your life.

Before we dive into the big questions of philosophy, you need to know how to argue properly. We’ll start with an overview of philosophical reasoning and breakdown of how deductive arguments work (and sometimes don’t work).

So we all know that breathing is pretty important, right? Today we're going to talk about how it works, starting with the nameless evolutionary ancestor that we inherited this from, continuing to the mechanics of both simple diffusion and bulk flow, as well as the physiology of breathing, and finishing with the anatomy of both the conducting zone and the respiratory zone of your respiratory system.

Today we are investigating our moral obligations to our parents and our families. Do we owe our parents anything as adults? Would it be a good idea to license parents? We’ll explore these questions as well as the ethics of care, and some potential problems that type of approach to morality carries with it.

Have you ever heard of a perpetual motion machine? More to the point, have you ever heard of why perpetual motion machines are impossible? One of the reasons is because of the first law of thermodynamics! In this episode of Crash Course Physics, Shini talks to us about thermodynamics and entropy. Also, we learn about isovolumetric, isobaric, isothermal, and adiabatic processes. It'll all make sense in a minute!

This week Craig Benzine explores the leadership structure of congress. We’ll break out the clone machine to examine the responsibilities of the speaker of the house, the majority and minority leaders, and the majority and minority whips in both the Senate and the House. As the leadership heavily influences assignments to committees and acts as the primary point of contact with the media, they wield significant power in influencing public dialog.
