What exactly is Consciousness? Well... that's kind of a gray area. In this episode of Crash Course Psychology, Hank gives you the basic ideas of what Consciousness is, how our attention works, and why we shouldn't text and drive... ever... no, really, NEVER!

In which John Green teaches you about the poetry of Sylvia Plath. When a lot of people think about Sylvia Plath, they think about her struggles with mental illness and her eventual suicide. Her actual work can get lost in the shuffle a bit, so this video really tries to focus on the poetry. You'll learn about Sylvia Plath's role as a feminist poet, and you'll also learn about her extraordinary ability to recreate the experiences of real life in beautiful and relatable way.
Hear John read all of Sylvia Plath's "Lady Lazarus" here:

Continuing our look at Nuclear Chemistry, Hank takes this episode to talk about Fusion and Fission. What they mean, how they work, their positives, negatives, and dangers. Plus, E=mc2, Mass Defect, and Applications of Fission and Fusion in the real world!

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 the different sorts of atoms in the universe, and it has a wealth of information to tell us if we can learn to read it.

How did we get here? Well, in terms of Atomic Chemistry, Hank takes us on a tour of the folks that were part of the long chain of other folks who helped us get to these deeper understandings of the world. From Leucippus to Heisenberg to you - yes, YOU - the story of Atomic Chemistry is all wibbly-wobbly... and amazing.

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, 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 - it's 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.

Now that we’ve finished our tour of the planets, we’re headed back to the asteroid belt. Asteroids are chunks of rock, metal, or both that were once part of smallish planets but were destroyed after collisions. Most orbit the Sun between Mars and Jupiter, but some get near the Earth. The biggest, Ceres is far smaller than the Moon but still big enough to be round and have undergone differentiation.
CORRECTION: In the episode we say that 2010 TK7 is 800 km away. However, 2010 TK7 stays on average 150 million kilometers from Earth, but that can vary wildly.
Sorry about that!

In which Jacob Clifford and Adriene Hill teach you about Economic Systems and Macroeconomics. So, economics is basically about choices. We'll look at some of the broadest economic choices when we talk about the difference between planned economies and market economies. We'll get into communism, socialism, command economies, and capitalism. We'll look at how countries choose the kind of system they're going to use (spoiler alert: many end up with mixed economies). We'll also look into how individuals make economic choices.

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 corrected for volume because atoms and molecules take up space and for pressure because they're attracted to each other; that Einstein was behind a lot more of what we know today than most people realize; and how a Dutch scientist named Johannes van der Waals figured out those correction factors in the late 19th century and earned a Nobel Prize for his efforts.

In this episode, Hank goes over Reversible Reactions, the water dissociation constant, what pH and pOH actually mean, Acids, Bases, and Neutral Substances as well as the not-so-terrifying Logarithms, strong acids, weak acids, and how to calculate pH and pOH. Oh, and litmus paper!

This week Craig Benzine takes a first look at the judicial branch. It's pretty easy to forget that the courts, and the laws that come out of them, affect our lives on a daily basis. But how exactly these decisions are made and where each law's jurisdiction starts and ends can get pretty complicated. So complicated in fact that you may want to smash something. But don't worry, Craig will clear the way.

You might have recognized the names of some of the Greek natural philosophers. They were individuals with quirky theories, and we have records about them. But they weren’t the only people making knowledge back in the day. Today, Hank takes us to India to talk Vedas, Maurya Empires, and some really good doctoring.

In which John Green teaches you about what is often called the Reagan Era. Mainly, it covers the eight years during which a former actor who had also been governor of the state of California was president of the United States. John will teach you about Reagan's election victory over the hapless Jimmy Carter, tax cuts, Reagan's Economic Bill of Rights, union busting, and the Iran-Contra among other things. Learn about Reagan's domestic and foreign policy initiatives, and even a little about Bonzo the Chimp.

As the Roman Empire fell, so did the theater. If there's anyone who hates theater and actors more than Romans, it's early Christians. As Christianity ascended in the west, theater declined. But, fear not. This isn't the end of the series. Theater would be back, and in the best subversive theater-y fashion, it would return via the Catholic mass!
