In which John Green teaches you about founding father and third president of the United States, Thomas Jefferson. Jefferson is a somewhat controversial figure in American history, largely because he, like pretty much all humans, was a big bundle of contradictions. Jefferson was a slave-owner who couldn t decide if he liked slavery. He advocated for small government but expanded federal power more than either of his presidential predecessor. He also idealized the independent farmer and demonized manufacturing, but put policies in place that would expand industrial production in the US. Controversy may ensue as we try to deviate a bit from the standard hagiography/slander story that is usually told about old TJ. John explores Jefferson s election, his policies, and some of the new nation s (literally and figuratively) formative events that took place during Jefferson s presidency. In addition to all this, Napoleon drops in to sell Louisiana, John Marshall sets the course of the Supreme Court, and John Adams gets called a tiny tyrant.

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 Chapters: Introduction 00:00 Alexander Hamilton s Vision for America 0:26 Thomas Jefferson s Vision for America 2:10 Democratic-Republicans vs. Federalists 3:32 George Washington and the First U.S. Presidential Election 4:33 Hamilton s Five-Point Plan 5:04 Republican Opposition to Hamilton s Economic Plan 6:20 The Whiskey Rebellion 7:02 Early U.S. Foreign Affairs 7:31 The End of Washington s Presidency 8:36 Mystery Document 9:21 John Adams Presidency 10:48 The Alien and Sedition Acts 11:56 Credits 13:24 Crash Course is on Patreon!

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.

The world s roundest object helps solve the longest running problem in measurement -- how to define the kilogram. Support Veritasium on Patreon: http://bit.ly/VePatreon A kilogram isn t what it used to be. Literally. The original name for it was the grave , proposed in 1793 but it fell victim to the French Revolution like its creator, Lavoisier. So begins the tale of the most unusual SI unit. The kilogram is the only base unit with a prefix in its name, and the only one still defined by a physical artifact, the international prototype kilogram or IPK. But the problem with this definition has long been apparent. The IPK doesn t seem to maintain its mass compared to 40 similar cylinders minted at the same time. The goal is therefore to eliminate the kilogram s dependence on a physical object. Two main approaches are being considered to achieve this end: the Avogadro Project and the Watt Balance. The Avogadro project aims to redefine Avogadro s constant (currently defined by the kilogram -- the number of atoms in 12 g of carbon-12) and reverse the relationship so that the kilogram is precisely specified by Avogadro s constant. This method required creating the most perfect sphere on Earth. It is made out of a single crystal of silicon 28 atoms. By carefully measuring the diameter, the volume can be precisely specified. Since the atom spacing of silicon is well known, the number of atoms in a sphere can be accurately calculated. This allows for a very precise determination of Avogadro s constant. Special thanks to Katie Green, Dr. David Farrant, the CSIRO, and the National Measurment Institute for their help. Thanks also to Nessy Hill for filming and reviewing earlier drafts of this video. There is debate as to whether this is truly the roundest object ever created. The Gravity Probe-B rotors are also spherical with very low tolerances such that they may in fact be rounder.
