All life on Earth— living and inanimate, microscopic and cosmic— is governed by mathematical laws with apparently arbitrary constants. And this opens up a question: If the universe is completely governed by these laws, couldn't a...

Paul Andersen explains pH as the power of hydrogen. He explains how increases in the hydronium ion (or hydrogen ion) concentration can lower the pH and create acids. He also explains how the reverse is true. An analysis of a strong...

In which John Green, Hank Green, and Emily Graslie teach you about, well, everything. Big History is the history of everything. We're going to start with the Big Bang, take you right through all of history (recorded and otherwise), and...

In this video Paul Andersen explains the importance of scale in science and engineering. The Universe varies in size along three scales: size, timespan, and energy. Many phenomenon are too small and fast, or two large and slow to...

How successful are we compared to other species? It turns out that biomass, or what things weigh, can be more important than how many of something there are. Find out how our numbers stack up against everything from bugs to bacteria, and...

People around the world are demanding clean air -- and cities are starting to respond, says electrification advocate Monica Araya. She takes us on a world tour of urban areas that are working to fully electrify their transportation...

In this video Paul Andersen explains how matter, like light, can be treated as both a particle and a wave. Louis de Broglie proposed that matter could act as a wave and described the wavelength of matter as a function of Planck's...

I took a trip to one of Austin's famous moontowers so I could put the enormity of our solar system into perspective. With the help of a grapefruit, and a lot of walking, you'll get an idea of just how tiny everything is out there!!

When they're used well, graphs can help us intuitively grasp complex data. But as visual software has enabled more usage of graphs throughout all media, it has also made them easier to use in a careless or dishonest way - and as it turns...

What is Skin For

New ReviewOrganizational Change and Business Transformation are terms Project Managers encounter a lot. And it can be tricky to distinguish between what we mean by change and transformation. Let’s have a go.

New ReviewIn this video, I will show you how to graph trigonometric functions, specifically focusing on cosecant (csc) and sine. We will examine how to identify key characteristics such as amplitude and period to effectively graph these functions....

New ReviewIn this video, I'll walk you through how to graph cosecant functions, especially when they include a phase shift. We'll cover the amplitude and period to accurately graph the cosecant graph by first understanding its related sine...

New ReviewThis video program compares mass and weight, while illustrating how these are measured. Metric units are used to measure these things using a scale or balance. The video correlates to the Next Generation Science Standard for Middle...

New Review“Types of Maps” explores different types of maps and how each type is used.

In this video students will observe that regardless of the type of change that occurs in heating, cooling, or mixing, the total weight of matter is conserved. A hands-on demonstration helps students set-up their own activity to prove...

In this shorts video we will determine scale using scale drawings and ratios. We will draw a picture to represent the drawing and the real world building. We will then write the ratio of drawing to building. We will identify the scale...

Discover how buoyancy and tension interact in this physics experiment! Learn why a wood sphere attached to a beaker changes the scale reading, even though it’s submerged like a steel sphere. Perfect for students exploring forces,...

Learn about buoyancy and pressure in this physics experiment! See why the scale reading stays the same, even with a steel sphere submerged. Perfect for students curious about forces, pressure, and fluid dynamics.<b<br/>r/>

Once you've got simple major and minor chords under your fingers, 7th barre chords are the next stage to make your playing sound more professional. Stuart Ryan shows you the relevance of the major 7, minor 7 and dominant 7 chords.

An extensive guide to the security perspective of the AWS Cloud Adoption Framework, covering nine key capabilities: security governance, security assurance, identity and access management, threat detection, vulnerability management,...
