Age of Jackson: Crash Course US History #14

In which John Green teaches you about the presidency of Andrew Jackson So how did a president with astoundingly bad fiscal policies end up on the $20 bill? That’s a question we can’t answer, but we can tell you how Jackson got to be president, and how he changed the country when he got the job. Jackson’s election was more democratic than any previous presidential election. More people were able to vote, and they picked a doozie. Jackson was a well-known war hero, and he was elected over his longtime political enemy, John Quincy Adams. Once Jackson was in office, he did more to expand executive power than any of the previous occupants of the White House. He used armed troops to collect taxes, refused to enforce legislation and supreme court legislation, and hired and fired his staff based on support in elections. He was also the first president to regularly wield the presidential veto as a political tool. Was he a good president? Watch this video and draw your own conclusions.

The Ideal Gas Law: Crash Course Chemistry #12

Gases are everywhere, and this is good news and bad news for chemists. The good news: when they are behaving themselves, it’s extremely easy to describe their behavior theoretically, experimentally and mathematically. The bad news is they almost never behave themselves. 
In this episode of Crash Course Chemistry, Hank tells how the work of some amazing thinkers combined to produce the Ideal Gas Law, how none of those people were Robert Boyle, and how the ideal gas equation allows you to find out pressure, volume, temperature or number of moles. You’ll also get a quick introduction to a few jargon-y phrases to help you sound like you know what you’re talking about. 

Slavery - Crash Course US History #13

In which John Green teaches you about America’s “peculiar institution,” slavery. I wouldn’t really call it peculiar. I’d lean more toward horrifying and depressing institution, but nobody asked me. John will talk about what life was like for a slave in the 19th century United States, and how slaves resisted oppression, to the degree that was possible. We’ll hear about cotton plantations, violent punishment of slaves, day to day slave life, and slave rebellions. Nat Turner, Harriet Tubman, and Whipped Peter all make an appearance. Slavery as an institution is arguably the darkest part of America’s history, and we’re still dealing with its aftermath 150 years after it ended.

How To Speak Chemistrian: Crash Course Chemistry #11

Learning to talk about chemistry can be like learning a foreign language, but Hank is here to help with some straightforward and simple rules to help you learn to speak Chemistrian like a native. 

The Market Revolution: Crash Course US History #12

In which John Green teaches you about the Market Revolution. In the first half of the 19th century, the way people lived and worked in the United States changed drastically. At play was the classic (if anything in a 30 year old nation can be called classic) American struggle between the Jeffersonian ideal of individuals sustaining themselves on small farms vs. the Hamiltonian vision of an economy based on manufacturing and trade. I’ll give you one guess who won. Too late! It was Hamilton, which is why if you live in the United States, you probably live in a city, and are unlikely to be a farmer. Please resist the urge to comment about this if you live in the country and/or are a farmer. Your anecdotal experience doesn’t change the fact that most people live in cities. In the early 19th century, new technologies in transportation and communication helped remake the economic system of the country. Railroads and telegraphs changed the way people moved goods and information around. The long and short of it is, the Market Revolution meant that people now went somewhere to work rather than working at home. Often, that somewhere was a factory where they worked for an hourly wage rather than getting paid for the volume of goods they manufactured. This shift in the way people work has repercussions in our daily lives right down to today. Watch as John teaches you how the Market Revolution sowed the seeds of change in the way Americans thought about the roles of women, slavery, and labor rights.
