There are some startlingly black animals out there, whether they’re in the deep ocean or in the darkest corners of the rainforest. But humans have created some stunningly black substances too, using science and engineering. So who wins, nature or humans? In this video, I go in search of the blackest black things on Earth to see what’s really the blackest… and why.

It never gets dark anymore. Not REALLY dark, anyway. Not like it used to. Light pollution is not only making it more difficult to see the night sky, but it's also affecting our health. For the past century and a half, since the dawn of electric light, we’ve been losing our connection to the night. We need artificial light for modern society, of course. The problem is, we need darkness for our health, and for the health of wildlife and ecosystems, and we’re not getting enough of it. I traveled to McDonald Observatory in far west Texas, one of the darkest places in North America, to learn what people are doing in order to preserve dark skies, and to see truly dark skies for myself (and so I could show them to you!). This video features time lapse night sky images that I’ve been collecting for the past few years, and I hope they make you feel something special. Turn out the lights, keep looking up, and don’t be afraid of the dark.

Today, FINALLY, Craig is going to talk about Free Speech! Now, free speech is so important because it not only allows you to critique the government, but it also protects you from the government. But it's essential to remember that not ALL speech is protected equally under the First Amendment, and just because you have a right to free speech doesn't mean your employer, for instance, can't fire you for something you say (unless your work for the government and then things get a bit more complicated). So we'll take a look at a couple significant Supreme Court cases that have gotten us to our current definition of free speech, and we'll also discuss some of the more controversial aspects of free speech - like hate speech.

This week Craig continues our conversation on presidential powers by looking at those NOT found in the Constitution - implied or inherent powers. We’ll talk about how the President uses their power to negotiate executive agreements, recommend legislative initiatives, instate executive orders, impound funds, and claim executive privilege in order to get things done. Implied powers are kind of tough to tack down, as they aren’t really powers until they’re asserted, but once they are, most subsequent Presidents chose not to give them up. So we’ll try to cover those we’ve seen so far and talk a little bit about reactions to these sometimes controversial actions from the other branches of Congress.

In order to understand the history of media literacy we have to go all the way back to straight up literacy. In the first half of our look at the history of media literacy, Jay takes us all the way back to Ancient Greece and forward through the printing press, newspapers, and Yellow Journalism.

What is a trade deficit? Well, it all has to do with imports and exports and, well, trade. This week Jacob and Adriene walk you through the basics of imports, exports, and exchange. So, you remember the specialization and trade thing, right? So, that leads to imports and exports. Economically, in the aggregate, this is usually a good thing. Globalization and free trade do tend to increase overall wealth. But not everybody wins.

Welcome to Crash Course Statistics! In this series we're going to take a look at the important role statistics play in our everyday lives, because statistics are everywhere! Statistics help us better understand the world and make decisions from what you'll wear tomorrow to government policy. But in the wrong hands, statistics can be used to misinform. So we're going to try to do two things in this series. Help show you the usefulness of statistics, but also help you become a more informed consumer of statistics. From probabilities, paradoxes, and p-values there's a lot to cover in this series, and there will be some math, but we promise only when it's most important. But first, we should talk about what statistics actually are, and what we can do with them. Statistics are tools, but they can't give us all the answers.

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 electrons jump from atom to atom, they carry energy with them, and that transfer of energy is what makes all life on Earth possible.
