Nachos are delicious. And versatile because today they're also going to help us learn a thing or two about your digestive system. Nachos can provide us with energy and raw materials, by first ingesting something nutritious, propelling it through the alimentary canal where it will be mechanically broken down, and chemically digested by enzymes until my cells can absorb their monomers and use them to make whatever they need. And eventually, there will be pooping.

Now that we've talked about your blood vessels, we're going to zoom in a little closer and talk about your blood itself. We'll start by outlining the basic components of blood -- including erythrocytes, leukocytes, platelets, and plasma -- as well as the basic process of hemostasis that stops bleeding, and how antigens are responsible for the blood type that you have. By the end of this episode, you should be totally prepared for your next blood drive.

In which Craig Benzine teaches you about the compromises met in ratifying the U.S. Constitution. The United States didn’t always have its current system of government. Actually, this is its second attempt. Craig will delve into the failures (and few successes) of the Articles of Confederation, tell you how delegates settled on a two-house system of representation, discuss the issues of slavery and population that have been embedded into our constitution, and fire up the clone machine to discuss how federalists and anti-federalist opposition provided the U.S. a Bill of Rights. And who knows, maybe all this talk of compromise will even inspire Craig and eagle to find some middle ground.

Empire, imperialism, and colonialism are all interrelated tactics of geopolitics that are used to achieve similar goals of one state maintaining economic, political, or even cultural dominance over other territories. Today, we’re going to unravel the impacts of colonialism at different times throughout history from Taiwan to Myanmar as we examine the longstanding impacts of these relationships. We’ll also take a look at how some countries today, like Thailand, have taken the control of the narrative through culinary colonization.

Even though you probably don't choose to spend a lot of time thinking about it, your pee is kind of a big deal. Today we're talking about the anatomy of your urinary system, and how your kidneys filter metabolic waste and balance salt and water concentrations in the blood. We'll cover how nephrons use glomerular filtration, tubular reabsorption, and tubular secretion to reabsorb water and nutrients back into the blood, and make urine with the leftovers.

Metabolism is a complex process that has a lot more going on than personal trainers and commercials might have you believe. Today we are exploring some of its key parts, including vital nutrients -- such as water, vitamins, minerals, carbs, fats, and proteins -- as well as how anabolic reactions build structures and require energy, while catabolic reactions tear things apart and release energy.

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?

Energy is like the bestest best friend ever and yet, most of the time we take it for granted. Hank feels bad for our friend and wants us to learn more about it so that we can understand what it's trying to tell us - like that any bond between two atoms contains energy. How much energy? That's not the simplest question to answer, but today Hank will answer it (kinda), by teaching us about a nifty little thing called enthalpy.
If you are paying attention to this episode you'll learn what the state function is, and how it varies from a path-dependent function; why enthalpy change is different from heat; that bonds are energy and to form and break them they release and absorb heat to and from their environment. You'll get the quickest introduction to calorimetry ever (more on that in upcoming episodes) and learn the power of Hess's Law and how to use Germain Hess's concept of the standard enthalpy of formation to calculate exactly how much heat is produced by any chemical reaction.

This week Craig Benzine talks about how the President gets things done. Filling the role of the Executive Branch is a pretty big job - much too big for just one person. It's so big that the President employs an entire federal bureaucracy! Today, we’re just going to focus on those closest to the President, like the Vice President, the Cabinet, and the Executive Office of the President. We’ll figure out which strategy is most useful in helping the President make things happen and we’ll discuss the controversy around the President’s gradual increase in power. Oh, and as many of you noticed - last episode eagle got off too easy. Let’s see if we can make it up to you.

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.

In which John Green teaches you about Sub-Saharan Africa! So, what exactly was going on there? It turns out, it was a lot of trade, converting to Islam, visits from Ibn Battuta, trade, beautiful women, trade, some impressive architecture, and several empires. John not only covers the West African Malian Empire, which is the one Mansa Musa ruled, but he also discusses the Ghanian Empire and even gets over to East Africa as well to discuss the trade-based city-states of Mogadishu, Mombasa, and Zanzibar. In addition to all this, John considers emigrating to Canada.

Today we are moving on from the existence of God to look at the philosophical debate surrounding the traditional divine attributes - omnipotence, omniscience, omnitemporality, and omnibenevolence. We are exploring the puzzles that these attributes create as well as some possible solutions to those puzzles, from Aquinas’ ideas of analogical predication, to the work of Eleanor Stump.

In which John Green teaches you how the Civil War played a large part in making the United States the country that it is today. He covers some of the key ways in which Abraham Lincoln influenced the outcome of the war, and how the lack of foreign intervention also helped the Union win the war. John also covers the technology that made the Civil War different than previous wars. New weapons helped to influence the outcomes of battles, but photography influenced how the public at large perceived the war. In addition, John gets into the long-term effects of the war, including the federalization and unification of the United States. All this plus homesteading, land grant universities, railroads, federal currency, and taxes.
