Crash Course!

Grumpy Professor Hank admits to being wrong about how everything is chemicals. But he now wants you to listen as he blows your mind with a new sweeping statement: everything (yes, really everything this time) is energy. Wh...

In which John Green teaches you about the Mexican-American War in the late 1840s, and the expansion of the United States into the western end of North America. In this episode of Crash Course, US territory finally reaches ...

We have learned over the past few weeks that gases have real-life constraints on how they move here in the non-ideal world. As with most things in chemistry (and also in life) how a gas moves is more complex than it at fir...

In which John Green teaches you that things don't always go as planned on the Crash Course set. Here we have outtakes from our Crash Course in Literature and some of the early US History episodes. Warning: there is some ce...

This week we continue to spend quality time with gases, more deeply investigating some principles regarding pressure - including John Dalton's Law of Partial Pressures, vapor pressure - and demonstrating the method for col...

In which John Green finally gets around to talking about some women's history. In the 19th Century, the United States was changing rapidly, as we noted in the recent Market Revolution and Reform Movements episodes. Things ...

Hank bursts our ideal gas law bubble, er, balloon, and brings us back to reality, explaining how the constants in the gas law aren't all that constant; how the ideal gas law we've spent the past two weeks with has to be co...

In which John Green teaches you about various reform movements in the 19th century United States. From Utopian societies to the Second Great Awakening to the Abolition movement, American society was undergoing great change...

We don't live in a perfect world, and neither do gases - it would be great if their particles always fulfilled the assumptions of the ideal gas law, and we could use PV=nRT to get the right answer every time. Unfortunately...

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...

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...

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 wha...

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.

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 yea...

All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemistry, which contains the majority of chemical reactions. As electro...

In which John Green teaches you about the War of 1812. The War of 1812 was fought between the United States and its former colonial overlord England. It started in, you guessed it 1812. The war lasted until 1815, and it re...

A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other that form an insoluble compound, they suddenly fall out of solution in what's called a precipitation reaction...

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 h...

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 ne...

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 opposit...

Sometimes words can be hard to say.

Dihydrogen monoxide (better know 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,...

In which John Green teaches you about the United States Constitution. During and after the American Revolutionary War, the government of the new country operated under the Articles of Confederation. While these Articles go...

Chemists need stoichiometry to make the scale of chemistry more understandable - Hank is here to explain why, and to teach us how to use it.

In which John Green teaches you about the American Revolution. And the Revolutionary War. I know we've labored the point here, but they weren't the same thing. In any case, John will teach you about the major battles of th...

Hank brings us the story of the electron and describes how reality is a kind of music, discussing electron shells and orbitals, electron configurations, ionization and electron affinities, and how all these things can be u...

In which John Green teaches you about the roots of the American Revolution. The Revolution did not start on July 4, 1776. The Revolutionary War didn't start on July 4 either. (as you remember, I'm sure, the Revolution and ...

Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of th...

In which John Green teaches you about the beginnings of the American Revolution in a video titled The Seven Years War. Confusing? Maybe. John argues that the Seven Years War, which is often called the French and Indian War...

Today's Crash Course Chemistry takes a historical perspective on the creation of the science, which didn't really exist until a super-smart, super-wealthy Frenchman put the puzzle pieces together - Hank tells the story of ...

In which John Green teaches you about some of the colonies that were not in Virginia or Massachussetts. Old New York was once New Amsterdam. Why they changed it, I can say; ENGLISH people just liked it better that way, and...

A unit is the frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the...

In which John Green teaches you about relations between the early English colonists and the native people the encountered in the New World. In short, these relations were poor. As soon as they arrived, the English were in ...
