Why do animals do what they do? It’s a huge question, and in this episode, we’ll learn how scientists break it down. We’ll talk about the proximate and ultimate studies they use to understand animal behavior, and some of what they’ve learned along the way — including how much decision-making other animals are really doing.
Chapters:
Introduction: Animal Behavior

When you think about the body’s infrastructure, you probably think of bones. But what about the heart, the blood vessels, and the lymphatic system? In this episode of Crash Course Biology, we’ll tour the cardiovascular, lymphatic, and musculoskeletal systems, learning how all of them keep a vertebrate’s inner workings connected, powered up, and ready to move.

Social behavior like caring for our young, fighting off rivals, joining a pack, or even fusing together into a huge super animal like the Power Rangers, adds a whole other layer of complexity to the lives of animals out there. And it even raises questions about being, culture, and what it means to be an individual. So today, we're going to dive into the amazing ways animals interact with other animals, live a day in the life of the Portuguese Man O'War, and learn how these complex social interactions can go way beyond anything humans are capable of!

The world is driven by fossil fuels like oil and gas. This has some negative repercussions: Rising energy prices due to decreasing deposits, dependence on unstable oil and gas producing regimes and global warming.
It becomes clear, that a revolution in the way how we produce and use energy is necessary. Central to this energy transition are new technologies, which produce energy from renewable sources such as wind or sun.
With Germany as an example, this clip shows what renewable energies are and how they work as well as what the concept of energy transition means.

The clip is part of the WissensWerte Project of the german non-profit organization /e-politik.de/ e.V.

Today, Clint will teach you about the Supreme Court confirmation hearing of Clarence Thomas. During the screening process, Anita Hill came forward alleging that Thomas had sexually harassed her when the two of them worked together at the Department of Education. The public response to Hill's allegations was tense and split the Black American community along gendered lines. Thomas's nomination was ultimately confirmed by a margin of 52-48, and he became the second Black American appointed to the U.S. Supreme Court.

Today we are introducing a new area of philosophy – philosophy of religion. We are starting this unit off with Anselm’s argument for God’s existence, while also considering objections to that argument.

This patient education program explains the causes and types of anthrax. It also reviews the symptoms, diagnosis, treatment, and prevention of anthrax through vaccination and awareness of bioterrorism. This resource is a MEDLINEplus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

In which John Green, Hank Green, and Emily Graslie teach you about the Anthropocene, an unofficial geological era that covers the last century or so, in which humanity has made massive progress. We've discovered the Higgs-Boson particle, and awesome electric cars, and amazing smartphones. So all this collective learning and progress has been good for everyone, right? Maybe not. We'll look at some of the pros and cons of all this "progress," including environmental impact, changes in the way people live and work, and political changes and wars that come along with the modern world. We've come a long way, but there's a long way to go. Crash Course will also take a look at what's going to happen in the near future. If we manage to make our way through the coming bottlenecks, we could be OK in coming centuries. Don't get too hopeful, though. The Sun will eventually die, and the Earth will be destroyed, and later the universe will eventually experience heat death. But we won't talk about those downers until next week.

Today we explore what obligations we hold with our personal beliefs. Hank explains epistemic responsibility and the issues it raises with everything from religious belief, to ship owning, to vaccinations.

The purpose of this video lesson is to expand the student's knowledge about enzymes by introducing the antioxidant enzymes that are intimately involved in the prevention of cellular damage and eventual slowing of the aging process and prevention of several diseases. Students will learn that natural antioxidant enzymes are manufactured in the body and provide an important defense against free radicals. The topic of free radical action is introduced, covering how they are constantly generated in living cells both by ''accidents of chemistry'' and also by specific metabolic processes.

This art history video discussion examines Antoine or Louis Le Nain's "Peasant Family in an Interior", 2nd quarter of the 17th century, oil on canvas (Musee du Louvre, Paris).

I don't mean it mean, but today we're going to be cruel. It's the fun-loving Theater of Cruelty, which was pioneered by the genius Antonin Artaud in France during the inter-war period in twentieth century. The Theater of Cruelty was meant to force an audience into looking at the ridiculous illusions of their bourgeois lives. Is it entertaining? Not always. Was it hugely influential? Absolutely.

Francis Ford Coppola's "Apocalypse Now" is a different kind of war movie. It's a multi-genre film that maybe says more about human psychology than it does about war. In this episode of Crash Course Film Criticism, Michael Aranda takes us on a trip through the Vietnam War through the eyes of a director at the end of his rope.

Mike Rugnetta is going to tell you stories of death, destruction, divine judgment, damnation, and the occasional happy ending. That's right, this week we're talking about the Apocalypse. Actually, we're talking about a bunch of ways the world could end. Prepare for stories of the end times from Judaism, Zoroastrianism, Christianity, and Islam! It's the (mostly) Abrahamic Apocalypses on Crash Course World Mythology.

Each lecture in this series focuses on a single play by Shakespeare, and employs a range of different approaches to try to understand a central critical question about it. Rather than providing overarching readings or interpretations, the series aims to show the variety of different ways we might understand Shakespeare, the kinds of evidence that might be used to strengthen our critical analysis, and, above all, the enjoyable and unavoidable fact that Shakespeare's plays tend to generate our questions rather than answer them.
