This week, Adriene and Jacob teach you about macroeconomics. This is the stuff of big picture economics, and the major movers in the economy. Like taxes and monetary policy and inflation and policy. We need this stuff, because if you don't have a big picture of the economy, crashes and panics are more likely. Of course, economics is extremely complex and unpredictable. Today we'll talk about GDP as a measure of a country's economic health, the basics of economic analysis, and even a little about full employment, unemployment

This week on Crash Course Econ, Jacob and Adriene are talking about failure. Specifically, we're talking about market failures. When markets don't provide a good or service efficiently, that's a market failure. When markets fail, often governments step in to provide those services. Stuff like public education or military protection are good examples of market failures. So, what are some of the ways governments address, market failures? Well, it's funny you should ask, as we also talk about that in this episode. We'll get into taxes and subsidies and externalities and a bunch of other important stuff this week on Crash Course Econ.

In which John Green teaches you about World War II, a subject so big, it takes up two episodes. This week, John will teach you how the United States got into the war, and just how involved America was before Congress actually declared war. John will actually talk a little about the military tactics involved, and he'll get into some of the weaponry involved, specifically the huge amount of aerial bombing that characterized the war, and the atomic bombs that ended the war in the Pacific.

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.
