What Does Dark Energy Really Do?
How does dark energy affect the universe's expansion? Measuring past expansion history should tell us the future expansion without ever having to count any galaxies. To measure this we need to measure the redshift-distance relationship,...

Fluids at Rest: Crash Course Physics
In this episode of Crash Course Physics, Shini is very excited to start talking about Fluids. You see, she's a Fluid Dynamicist and Mechanical Engineer, so fluids are really important to her. Actually they're really important to anyone...

Light
In order to understand how we study the universe, we need to talk a little bit about light. Light is a form of energy. Its wavelength tells us its energy and color. Spectroscopy allows us to analyze those colors and determine an object’s...

The Missing Mass Mystery
For years, astronomers have been unable to find up to half of the baryonic matter in the universe. We may just have solved this problem.

TED-ED: How do we separate the seemingly inseparable? - Iddo Magen
Your cell phone is mainly made of plastics and metals. It's easy to appreciate the process by which those elements add up to something so useful. But there's another story we don't hear about -- how did we get our raw ingredients in the...

Bernoulli's Equation
In the video Paul Andersen explains how Bernoulli's Equation describes the conservation of energy in a fluid. The equation describes the pressure energy, potential energy, and kinetic energy of a fluid at a single point. A sample problem...

Continuity Equation
In this video Paul Andersen explains how the continuity equation is an application of conservation of matter in a fluid. The continuity equation may apply to either mass or volumetric flow. Example problem and examples are included.

Why does ice float?
Why does ice float? You might not think about it, but this special property of frozen water is what makes your iced tea tinkle and makes a lot of aquatic life possible. Hank gets in touch with his inner Olaf to explain the wonder that is...

Fluid Flow & Equipment: Crash Course Engineering #13
Today we’ll dive further into fluid flow and how we can use equipment to apply our skills. We explain Bernoulli’s Principle and the relationship between speed and pressure in certain flowing fluids. We’ll also discuss how to apply the...

Density
In this video Paul Andersen explains how density measures the compactness of a material. You can calculate the density of a material by measuring the mass and dividing this by the volume. Water displacement is an effective way to measure...
