In which John Green teaches you about the New Deal, which was president Franklin D. Roosevelt's plan to pull the United States out of the Great Depression of the 1930s. Did it work? Maybe. John will teach you about some of the most effective and some of the best-known programs of the New Deal. They weren't always the same thing. John will tell you who supported the New Deal, and who opposed it. He'll also get into how the New Deal changed the relationship between the government and citizens, and will even reveal just how the Depression ended. (hint: it was war spending)

Today we're going to talk about rivers and how these dynamic, delicate, yet powerful systems are able to constantly change the landscape. We'll focus on the Zambezi River in Southeast Africa following its main features from the tributaries that feed into it in the upper course, to the deafening wonder that is Mosi-oa-Tunya waterfall (also called as Victoria Falls) in the middle course, all the way to the delta as the river flows into the Indian Ocean. Along the way, we'll teach you all about why rivers meander, why some rivers have rapids and others are calm, and how we talk about classify and river systems more broadly.

In this episode, Hank talks about Network solids and Carbon and how you can actually create a Diamond from plain old Carbon... well, YOU probably can't unless you own a bunch of elephants. It's a long story. BUT, within you will learn about Solid Networks, Diamond and Graphite Network Structures, as well as Sheet and 3D Networks. It's not making diamonds from scratch, but it's still pretty cool!
