The purpose of this learning video is to show students how to think more freely about math and science problems. Sometimes getting an approximate answer in a much shorter period of time is well worth the time saved. This video explores techniques for making quick, back-of-the-envelope approximations that are not only surprisingly accurate, but are also illuminating for building intuition in understanding science. This video touches upon 10th-grade level Algebra I and first-year high school physics, but the concepts covered (velocity, distance, mass, etc) are basic enough that science-oriented younger students would understand. If desired, teachers may bring in pendula of various lengths, weights to hang, and a stopwatch to measure period. Examples of in- class exercises for between the video segments include: asking students to estimate 29 x 31 without a calculator or paper and pencil; and asking students how close they can get to a black hole without getting sucked in.

The Harlem Renaissance was one of the richest, most vibrant, and most culturally generative artistic periods in American history and the work that emerged from that period continues to shape the landscape of American arts and letters today. In this episode, we’re going to explore some of the writers, artists, and musicians who turned Harlem into a world-renowned hub of art and culture, and delve into the factors that brought them all together in the first place.

In which John Green teaches you about Imperialism, but not from the perspective of the colonizers. This week John looks at some Asian perspectives on Imperialism; specifically, writers from countries that were colonized by European powers. We'll look at the writings of Sayyid Jamal ad-Din al-Afghani from the Middle East, Liang Qichao from China, and Rabindranath Tagore from India. these voices from the countries that were colonized give us a sense of how conquered people saw their conquerors, and give an insight into what these nations learned from being dominated by Europe. It's pretty interesting, OK? A lot of this episode is drawn from a fascinating book by Pankaj Mishra called The Ruins of Empire: The Revolt Against the West and the Remaking of Asia. You should read it.

Explore some of the wonders of modern engineering in this video from the Sciencenter in Ithaca, New York. Hear a diverse selection of engineers explain how things work.

As we wrap up Crash Course Philosophy, we’re using the things we’ve learned to explore big issues like the value of life. Today, we’re discussing abortions in cases of fetal abnormality, assisted suicide, and euthanasia. We will consider the standard of substituted judgment and the values people hold on both sides of these issues—values about the sacredness of life, and the importance of a life of quality, as well as the values of personal liberty and avoiding pain.

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 has 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!

This patient education program explains asthma including the causes, symptoms, and treatment of the disease. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

It's time for the end. At least the end of our first series on physics here at Crash Course. In this episode of Crash Course Physics, Shini sits down to talk about astrophysics and cosmology. By using what we've learned this year, we can better understand our universe. Join us for this final episode of Crash Course Physics as we head into the final frontier.

Aswaat Arabiyya is an archive of 245 videos in Arabic, listed by difficulty level and accompanied by glossaries and four worksheets each that focus on every aspect of listening comprehension. Selections come largely from Arabic media, with some cultural presentations by native speakers. Videos cover the entire Arabic-speaking world and include MSA and different dialects. Materials are designed to be used both as in-class activities and homework assignments. Videos can be slowed down.

PowerPoint Tutorial on the different program windows elements that make up the user interface. We examine the PowerPoint Title Bar, PowerPoint Ribbons and PowerPoint Status Bar.

Today, Andre is going to talk about the rise of Atari and with it the rise of the video game industry. So if you remember from last episode, we mentioned that the first arcade machine, Galaxy Game, happened to have a coin slot, but this was just the beginning. Nolan Bushnell, often considered the Father of the Video Game Industry, saw the opportunity for the commercialization of video games. Bushnell founded Atari and oversaw the development of its first game - Pong. And then, through some questionably ethical business strategies, Bushnell was able to get his machines into arcades all across the United States. But if this is all Atari had done, we probably wouldn’t be dedicating an entire episode to it. Atari also played a major role in getting video games into the home with the Atari 2600 console. Video games were becoming a part of peoples’ everyday lives and they were becoming a part of popular culture. But Atari wasn’t the only video game company in the 1970s, it wasn’t even the first. So we’re going talk about some of the other companies that took part in the war for a place in our living rooms next week!

This Wide Angle video segment illustrates Islamic and secular elements of life in Turkey, and introduces Mustafa Kemal Ataturk, the first president of Turkey, and his reforms.

In which John Green teaches you about one of the least funny subjects in history: slavery. John investigates when and where slavery originated, how it changed over the centuries, and how Europeans and colonists in the Americas arrived at the idea that people could own other people based on skin color.

Slavery has existed as long as humans have had civilization, but the Atlantic Slave Trade was the height, or depth, of dehumanizing, brutal, chattel slavery. American slavery ended less than 150 years ago. In some parts of the world, it is still going on. So how do we reconcile that with modern life? In a desperate attempt at comic relief, Boba Fett makes an appearance.

Chapters:
Introduction
The Atlantic Slave Trade
The History of European Slave Trade
How Africans Became Enslaved
Living Conditions of Enslaved People
An Open Letter to the Word 'Slave'
What is the Definition of Slavery?
Other Models of Slavery: Greek, Roman, Judeo-Christian, and Muslim

The story picks up where we left off last time, with Einstein writing the president of his new homeland, the United States, urging him to build a nuclear weapon before Hitler. This is the tale of the most destructive force humans have ever unleashed. The Atomic Bomb.

Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are. Unlike human relationships, we can analyze exactly what makes chemical relationships work, and that's what this episode is all about.

If you are paying attention, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law.
