Art is the perfect tool for activists to get across their message and make people pay attention. In this episode of Crash Course Art History, we’ll learn about the centuries-long practice of iconoclasm, how art intersects with protest movements, and what happens to artists when the authorities aren’t thrilled by their acts of resistance.

Last week, Hank talked about how stuff mixes together in solutions. Today, and for the next few weeks, he will talk about the actual reactions happening in those solutions - atoms reorganizing themselves to create whole new substances in the processes that make our world the one we know and love. This week, we focus on acids and bases and their proton-exchanging ways.

Hank resists the urge to devour a slice of pizza so that he can walk you through the way we experience our major special senses. It all boils down to one thing: sensory cells translate chemical, electromagnetic, and mechanical stimuli into action potentials that our nervous system can make sense of. Today we're focusing on smell (olfaction) and taste (gustation), which are chemical senses that call on chemoreceptors. As usual, we'll begin with a quick look at how these things can go wrong.

In which John Green teaches you where American politicians come from. In the beginning, soon after the US constitution was adopted, politics were pretty non-existent. George Washington was elected president with no opposition, everything was new and exciting, and everyone just got along. For several months. Then the contentious debate about the nature of the United States began, and it continues to this day. Washington and his lackey/handler Alexander Hamilton pursued an elitist program of federalism. They attempted to strengthen the central government, create a strong nation-state, and leave less of the governance to the states, They wanted to create debt, encourage manufacturing, and really modernize the new nation/ The opposition, creatively known as the anti-federalists, wanted to build some kind of agrarian pseudo-paradise where every (white) man could have his own farm, and live a free, self-reliant life. The founding father who epitomized this view was Thomas Jefferson. By the time Adams became president, the anti-federalists had gotten the memo about how alienating a name like anti-federalist can be. It's so much more appealing to voters if your party is for something rather than being defined by what you're against, you know? In any case, Jefferson and his acolytes changed their name to the Democratic-Republican Party, which covered a lot of bases, and proceeded to protest nearly everything Adams did. Lest you think this week is all boring politics, you'll be thrilled to hear this episode has a Whiskey Rebellion, a Quasi-War, anti-French sentiment, some controversial treaties, and something called the XYZ Affair, which sounds very exciting. Learn all about it this week with John Green.

Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. Much of America's politics came from debates between democratic republican Thomas Jefferson and federalist Alexander Hamilton: https://www.commonlit.org/texts/alexander-hamilton
While Jefferson would go on to become president, Hamilton heavily influenced President George Washington who set many American political ideals in his farewell address that Hamilton helped craft: https://www.commonlit.org/texts/washington-s-farewell-address

Dihydrogen monoxide (better known as water) is the key to nearly everything. It falls from the sky, makes up 60% of our bodies, and just about every chemical process related to life takes place with it or in it. Without it, none of the chemical reactions that keep us alive would happen - none of the reactions that sustain any life form on earth would happen - and the majority of inorganic chemical reactions that shape the surface of the earth would not happen either. Every one of us uses water for all kinds of chemistry every day - our body chemistry, our food chemistry, and our laundry chemistry all take place in water.

In today's Crash Course Chemistry, we use Hank's actual dirty laundry (ew) to learn about some of the properties of water that make it so special - its polarity and dielectric property; how electrolytes can be used to classify solutions; and we discover how to calculate a solution's molarity as well as how to dilute a solution using the dilution equation.
