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.

**Special Thanks to Matt Young at the University of Montana (Geosciences Department, Environmental Biogeochemistry Lab) who helped with the chemical demonstrations.**

When collecting data to make observations about the world it usually just isn't possible to collect ALL THE DATA. So instead of asking every single person about student loan debt for instance we take a sample of the population, and then use the shape of our samples to make inferences about the true underlying distribution our data. It turns out we can learn a lot about how something occurs, even if we don't know the underlying process that causes it. Today, we’ll also introduce the normal (or bell) curve and talk about how we can learn some really useful things from a sample's shape - like if an exam was particularly difficult, how often old faithful erupts, or if there are two types of runners that participate in marathons!

Description

chant bulgare par les Cosmic Voices from Bulgaria

Our exploration of ethical theories continues with another theistic answer to the grounding problem: natural law theory. Thomas Aquinas’s version of this theory says that we all seek out what’s known as the basic goods and argued that instinct and reason come together to point us to the natural law. There are, of course, objections to this theory – in particular, the is-ought problem advanced by David Hume.

Dios te salve, Reina y Madre de misericordia,
vida, dulzura y esperanza nuestra.

Dios te salve.

A Tí clamamos los desterrados hijos de Eva,
a Tí suspiramos, gimiendo y llorando en este valle de lágrimas.

Ea, pues, Señora Abogada Nuestra,
vuelve a nosotros tus ojos misericordiosos,
y después de este destierro, muéstranos a Jesús,
fruto bendito de tu vientre.

Oh, clemente, oh piadosa, oh dulce Virgen María.

Ruega por nosotros, Santa Madre de Dios,
para que seamos dignos de alcanzar las promesas de Nuestro Señor Jesucristo.

Amén

Today, we're going to discuss how numbers, like statistics, and visual representations like charts and infographics can be used to help us better understand the world or profoundly deceive. Data is a really powerful form of evidence because it can be absorbed quickly and easily, but neither data, nor interpretations of it, are neutral, so today we're going to discuss how to think critically about the statistics we encounter in everyday life.

Our final episodes of Anatomy & Physiology explore the way your body keeps all that complex, intricate stuff alive and healthy -- your immune system. The immune system’s responses begin with physical barriers like skin and mucous membranes, and when they’re not enough, there are phagocytes -- the neutrophils and macrophages. It also features the awesomely named natural killer cells and the inflammatory response, and we'll explain how all of these elements work together to save the day if you happen to slip on a banana peel.

We love the internet! It's a wealth of information where we can learn about just about anything, but it's also kind of a pit of information that can be false or misleading. So, we're partnering with Mediawise and the Stanford History Education Group to make this series on Navigating Digital Information. Let's learn the facts about facts!
