  Reader, it's Jane Eyre - Crash Course Literature 207 25.09.2026 17мин

  In which John Green teaches you about Charlotte Brontë's classic coming of age novel, Jane Eyre. Look, we don't like to make judgment values here, but Jane Eyre is awesome. By which we mean the book is great, and the character is amazing. When Jane Eyre was published in 1847, it was a huge hit. It really hit the controversial balance beautifully, being edgy enough to make news, but still mainstream enough to be widely popular. It was sort of like the Fight Club of its day, but not quite as testosterone-fueled. You'll learn a little about the story, learn about Jane as a feminist heroine, and even get some critical analysis on how Bertha might just be a dark mirror that acts out Jane's emotional reactions.Consider supporting local bookstores by purchasing your books through our Bookshop affiliate link https://bookshop.org/shop/complexly​ or at your local bookseller.Crash Course is on Patreon!

  Tyranny of the Map: Crash Course Geography #35 25.09.2026 15мин

  Today we’re going to talk about borders. Borders can bring people together, evoke passion and war, divide, conquer, and solidify power. We’re going to focus on the tyranny of the map which is what happens when those in power draw boundaries in ways that conflict with how people in that place want to be grouped. We’ll look at the repercussions of the Berlin Conference of 1884 on boundaries within Africa, take a closer look at continued political unrest in Mali, and look at how this can even happen at a local level like when gerrymandering occurs within a US state.
