Interactions between species are what define ecological communities, and community ecology studies these interactions anywhere they take place. Although interspecies interactions are mostly competitive, competition is pretty dangerous, so a lot of interactions are actually about side-stepping direct competition and instead finding ways to divvy up resources to let species get along. Feel the love?

Propaganda! Misinformation! Disinformation! Today we’re talking about the dark – or, shall we say, darkER – side of media. Understanding these media bogeymen is essential to being a more media literate citizen.

Today we kick off Crash Course Sociology by explaining what exactly sociology is. We’ll introduce the sociological perspective and discuss how sociology differentiates itself from the other social sciences. We’ll also explore what sociology can do, and how a concern with social problems was at the center of sociology's beginnings.

Welcome to Crash Course Statistics! In this series we're going to take a look at the important role statistics play in our everyday lives, because statistics are everywhere! Statistics help us better understand the world and make decisions from what you'll wear tomorrow to government policy. But in the wrong hands, statistics can be used to misinform. So we're going to try to do two things in this series. Help show you the usefulness of statistics, but also help you become a more informed consumer of statistics. From probabilities, paradoxes, and p-values there's a lot to cover in this series, and there will be some math, but we promise only when it's most important. But first, we should talk about what statistics actually are, and what we can do with them. Statistics are tools, but they can't give us all the answers.

Today we’re looking at silicon, and how introducing small amounts of other elements allow silicon layers to conduct currents, turning them into semiconductors. We’ll explore how putting two different types – N and P semiconductors – together gives us electrical components like diodes, transistors, and solar cells.

Today we’ll continue to explore sociology’s founding theorists with a look at Karl Marx and his idea of historical materialism. We’ll discuss modes of production, their development, and how they fit into Marx’s overall theory of historical development, along with class struggle and revolution. We’ll also discuss how Marx’s ideas gave rise to Gramsci’s idea of hegemony, and to conflict theories more generally.
