Sensation and Perception: Crash Course Psychology #5

The carbon dioxide we’re pumping into the air every day is causing unprecedented global warming and climate change. In this episode of Crash Course Climate and Energy, we’ll give you a better understanding of the types of energy that cause carbon emissions, and discuss the disparities between the countries with the most emissions and those already facing the worst effects of climate change.

In which John Green continues to teach you about Slaughterhouse-Five by Kurt Vonnegut. (WARNING: When Slaughterhouse-Five was published, some of the crude language in the book caused controversy. We quote one mildly controversial line in this video. If you're mature enough to read this book, you're likely mature enough to tolerate this quote, but we're obliged to warn you about it.) Anyway, this week, John is going to talk about Slaughterhouse-Five's status as an anti-war novel, and what exactly anti-war novels are good for. He'll also get into the idea of free will, and to what degree Billy Pilgrim's time travel and abduction by aliens were hallucinations induced by posttraumatic stress disorder. John will even give you an interpretation of why the Tralfamadorians look like toilet plungers. Hint: it has to do with plunging metaphorical toilets.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!

Nearly a third of all our greenhouse gas emissions come from generating electricity. Scientists agree that we have to find ways to make electricity without releasing so much carbon dioxide into the air. In this episode of Crash Course Climate and Energy, we’re going to tell you about some of the ways scientists and engineers are decarbonizing the electricity supply with energy sources such as solar, wind, nuclear, and hydroelectric and the benefits and drawbacks of each.Chapters:Introduction: Decarbonizing Electricity 00:00Electricity From Solar & Wind Power 2:05Challenges of Solar & Wind Power 3:36Hydroelectric Power 6:46Nuclear Power 8:21Why Carbon-Free Electricity Matters 9:52Review & Credits 11:35Sources: https://docs.google.com/document/d/1rRJ-L9TLNfPwPfzn3LdjDEw-wHtThwTfDUe2rDtFXQQ/edit?usp=sharing***Crash Course is on Patreon!

We used to think that the human brain was a lot like a computer; using logic to figure out complicated problems. It turns out, it's a lot more complex and, well, weird than that. In this episode of Crash Course Psychology, Hank discusses thinking & communication, solving problems, creating problems, and a few ideas about what our brains are doing up there.
