Pre-order our book YOU ARE AN ARTIST (which includes new assignments!) here: http://bit.ly/2kplj2h In which we go to The Kemper Museum of Contemporary Art in Kansas City, Missouri, and give you some pointers on how to visit an art museum. Seems easy enough, but there are ways to maximize your experience. What are your museum tricks and tips? Let's talk about it in the comments!

Many thanks to The Kemper Museum of Contemporary Art for giving us access to their wonderful institution. Their admission is free, but they can only do this because of donations and memberships. So while we joke that you should always find a way to get in for free, you should also consider supporting your local institutions whenever you can and in whatever way you can. This can be through membership, donations, attending events, or volunteering your time. (And if you happen to have an amazing art collection of your own, you should will it to a museum. Really. Your grandchildren won't appreciate it nearly as much as an entire city will for many generations to come.)

A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other and form an insoluble compound, they suddenly fall out of the solution in what's called a precipitation reaction. In this episode of Crash Course Chemistry, we learn about precipitation, precipitates, anions, cations, and how to describe and discuss ionic reactions.

Today we're going to talk about a fundamental part of all modern computers. The thing that basically everything else uses - the Arithmetic and Logic Unit (or the ALU). The ALU may not have to most exciting name, but it is the mathematical brain of a computer and is responsible for all the calculations your computer does! And it's actually not that complicated. So today we're going to use the binary and logic gates we learned in previous episodes to build one from scratch, and then we'll use our newly minted ALU when we construct the heart of a computer, the CPU, in episode 7.

*CORRECTION*

We got our wires crossed with the Intel 4004, which we discuss later. The 74181 was introduced by Texas Instruments in 1970 but appeared in technical manuals around 1969. The design of the 74181, like most of the 74xx/74xxx series, was an open design which was manufactured by many other companies - Fairchild was one such manufacturer. They produced a chip, the Fairchild 9341, which was pin-for-pin compatible with the 74181.

Fairchild was the first to prototype an ALU, building the Fairchild 4711 in 1968 - a one-off device not optimized for scale manufacturing. In 1969, Signetics came out with the 8260, which they marketed in a very limited sense (it was attached, AFAICT, to one particular computer, the Data General SUPERNOVA). TI follows afterwards (March 1970) with the 74181, coupled with the 9341 from Fairchild. The 74181 became the standard number for this part, and was available from many manufacturers (back in those days, chip makers cross-licensed designs all over the place in order to provide assurance that their part could be sourced from multiple manufacturers).

SARS-CoV-2 and COVID-19 are nasty enemies. Invisible, mysterious, and deadly, they have spread around the world and caused much of humanity to hide away. Germs like these only succeed and spread because of our social evolution, and our social nature is why social and physical distancing is so deeply painful for us. But evolution has also given us the gifts we need to survive this difficult time.

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?

Here's why you aren't built like a lobster.

Our bodies are mirror images of lobsters and other arthropods from back to belly. We've know since the early 19th century that our guts and nervous systems are inverted from theirs, but only recently has molecular biology shown us why. Here's the evolutionary tale about a worm doing the backstroke and why your guts are on your front.

This is part 2 of 3 in my series about how our bodies evolved to look like they do. Check out the others:

Today, we’re going to take a closer look at borders and the stories they tell. When we look at a map, the shapes we’re seeing can seem so permanent, but a map is just a snapshot of the Earth at a particular time, and by looking a countries shape (and how it has changed across time) we can learn so much about how power moves and the ebb and flow of conflict. We’ll talk about the different types of borders, and power dynamics at play in Armenia and Azerbaijan and even look to the oceans as we explore conflict in the South China Sea.

It never gets dark anymore. Not REALLY dark, anyway. Not like it used to. Light pollution is not only making it more difficult to see the night sky, but it's also affecting our health. For the past century and a half, since the dawn of electric light, we’ve been losing our connection to the night. We need artificial light for modern society, of course. The problem is, we need darkness for our health, and for the health of wildlife and ecosystems, and we’re not getting enough of it. I traveled to McDonald Observatory in far west Texas, one of the darkest places in North America, to learn what people are doing in order to preserve dark skies, and to see truly dark skies for myself (and so I could show them to you!). This video features time lapse night sky images that I’ve been collecting for the past few years, and I hope they make you feel something special. Turn out the lights, keep looking up, and don’t be afraid of the dark.

In which John Green teaches you about the United States in the 1920s. They were known as the roaring 20s, but not because there were lions running around everywhere. In the 1920s, America's economy was booming, and all kinds of social changes were in progress. Hollywood, flappers, jazz, there was all kinds of stuff going on in the 20s. But as usual with Crash Course, things were about to take a turn for the worse. John will teach you about the Charleston, the many Republican presidents of the 1920s, laissez-faire capitalism, jazz, consumer credit, the resurgent Klan, and all kinds of other stuff.

In which John Green teaches you about Imperialism, but not from the perspective of the colonizers. This week John looks at some Asian perspectives on Imperialism; specifically, writers from countries that were colonized by European powers. We'll look at the writings of Sayyid Jamal ad-Din al-Afghani from the Middle East, Liang Qichao from China, and Rabindranath Tagore from India. these voices from the countries that were colonized give us a sense of how conquered people saw their conquerors, and give an insight into what these nations learned from being dominated by Europe. It's pretty interesting, OK? A lot of this episode is drawn from a fascinating book by Pankaj Mishra called The Ruins of Empire: The Revolt Against the West and the Remaking of Asia. You should read it.

So far, the rulers of Europe have been working to consolidate their power and expand their kingdoms, and this is it. The moment they've been working toward: Absolute Monarchy. We're going to learn about how kings and queens became absolute rulers in Europe, and where better to start than with Louis XIV of France, who is really the model for absolute rule.

#CrashCourse #EuropeanHistory #history

Today we're going to learn about perhaps the best-known leader in the Civil Rights Era, Martin Luther King, Jr. From his rise to notoriety during the Montgomery Bus Boycott in 1955, his leadership of the Southern Christian Leadership Conference, the March on Washington in 1963, his work toward the Civil Rights and Voting Rights Acts of the mid-1960s, and his assassination in 1968, Dr. King is very broadly known. But maybe he isn't that well understood. Like many extremely famous people, Martin Luther King can sometimes be drawn as a bit of a flat character, and his ideas can be reduced to platitudes. Today we'll try to give you a fuller picture of the man and leader he was.
