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.

The difference between atomic weight and atomic mass in chemistry, and how it compares to the physics definitions of weight and mass.

This lesson focuses on Audacity, a free audio editing application. Each lesson begins with one or more YouTube tutorials and an exercise based on the tutorial content which can be saved for evaluation. It concludes with a final assessment which can be used to evaluate the user's ability to use the application.

AR transforms traditional learning into an immersive, interactive experience. By blending real-world environments with digital enhancements, it fosters better engagement, understanding, and retention of information.

UniProt is a high quality, comprehensive protein resource in which the core activity is the expert review and annotation of proteins where the function has been experimentally investigated. At the same time the UniProt database contains large numbers of proteins which are predicted to exist from gene models, but which do not have associated experimental evidence indicating their function. UniProt commits significant resources to developing computational methods for functional annotation of these predicted proteins based on the data in entries that have gone through the expert review process.

We will describe the two main automated annotation systems currently in use. First, UniRule, which is an established UniProt system in which curators manually develop rules for annotation. Second ARBA (Association-Rule-Based Annotator), which has recently been introduced as a significant improvement in fully automated functional annotation. ARBA is a multiclass learning system which uses rule mining techniques to generate concise annotation models. ARBA employs a data exclusion set that censors data not suitable for computational annotation, and generates human-readable rules for each UniProt release.

We will also briefly touch on the mechanism UniProt has set up to enable researchers to run these automated annotation systems on their own protein datasets.

Who is this course for?
This webinar is for scientists and bioinformaticians with an interest in functional annotation of protein sequences.

Basic overview of the Autonomic Nervous system along with their respective receptors and neurotransmitters.

Hank takes you on a tour of your two-part autonomic nervous system. This episode explains how your sympathetic nervous system and parasympathetic nervous system work together as foils, balancing each other out. Their key anatomical differences - where nerve fibers originate and where their ganglia are located - drive their distinct anatomical functions, making your sympathetic nervous system the "fight or flight" while your parasympathetic nervous system is for "resting and digesting."

In this video segment from TV411, figure skaters compute their average daily practice time.

This learning video continues the theme of an early BLOSSOMS lesson, Flaws of Averages, using new examples—including how all the children from Lake Wobegon can be above average, as well as the Friendship Paradox. As mentioned in the original module, averages are often worthwhile representations of a set of data by a single descriptive number. The objective of this module, once again, is to simply point out a few pitfalls that could arise if one is not attentive to details when calculating and interpreting averages. Most students at any level in high school can understand the concept of the flaws of averages presented here. The essential prerequisite knowledge for this video lesson is the ability to calculate an average from a set of numbers. Materials needed include: pen and paper for the students; a blackboard or equivalent; and coins (one per student) or something similar that students can repeatedly use to create a random event with equal chances of the two outcomes (e.g. flipping a fair coin). The coins or something similar are recommended for one of the classroom activities, which will demonstrate the idea of regression toward the mean. Another activity will have the students create groups to show how the average number of friends of friends is greater than or equal to the average number of friends in a group, which is known as The Friendship Paradox. The lesson is designed for a typical 50-minute class session.

About 70% of our planet is covered by oceans and seas: large, full of life and mysterious.
They are a source of food, way of transportation, oxygen producer, and more.

But the sea is in danger: overfishing, plastic waste, acidification, species extinction.
We need to better understand the marine life and deal with it in a sustainable way, because our life is closely linked to the sea. If it is sick, we cannot stay healthy.

How should we understand Ayn Rand’s political philosophy? In this video, Professor Jennifer Burns of the University of Virginia argues that Rand belongs to the classical liberal tradition.

Nearly Everything You Need To Know About the Aztecs Can Be Found Within the Sacred Precinct.

This engaging video examines the most important part of the entire Aztec world: the literal center of the Universe: The Sacred Precinct of Mexico-Tenochtitlan. Now, nearly everything you need to know about the Aztecs can be found within this sacred space located in the center of its majestic city: Tenochtitlan. There’s about 78 structures, although all of them haven’t been found yet…. But these buildings can you teach you nearly everything… about the Culhua Mexica. You can learn about Aztec religion…. Social structure… architecture… engineering… sports… their cleanliness.

Model of Sacred Precinct is located at the Mexican National Museum of Anthropology and History.
