In this video Paul Andersen details the important structures and functions of the integumentary system. The integumentary system includes the skin, hair and nails in humans.

Rockets are super amazing, but how do we get something that weighs as much as 100 elephants all the way into space?

You probably won't get stuck in quicksand. But if you do, you can use physics to get yourself out.

What if we could harness the sticking powers of sea creatures like mussels, oysters and barnacles, which refuse to budge even on wet, stormy coastlines? Dive into the wonderful world of animals that make their own glue and cement with...

Paul Andersen defines the major elements of feedback loops. The receptors and effectors both sense and respond to changes in their environment. The following examples are used to illustrate the importance of feedback loops in...

Imagine a cup of tea that doesn't obey the laws of physics, it pours out of the bottom of your cup while crawling up the sides to the top, and you'll have a pretty good picture of the ultracold phenomena of superfluids.

The science of hot air balloons may surprise you.

If you ask someone to picture a thunderstorm, chances are they will have no problem slipping into a memory of dark clouds and bright flashes screaming out from them. But, incredibly, they’re probably picturing the tame version of...

Meet some of the world’s tiniest animals -- micro-animals, that can live at the bottom of the ocean, on our skin, even in space!

It's true. You have tiny mites living all around your face. But who are they? And how did they get there? QQ has the A!

Is it in the Arctic Ocean? In Canada? Russia?

In 1963, Jacques Cousteau lived for 30 days in an underwater laboratory positioned on the floor of the Red Sea, and set a world record in the process. This summer, his grandson Fabien Cousteau broke that record. Cousteau the younger...

Today we’re exploring social mobility in some more depth. We’ll look at intergenerational and intragenerational mobility and the difference between absolute and relative mobility. We’ll go over the long run upward social mobility trends...

Hank and Dr. Rebecca Bendick talk about her work in the science of earthquake forecasting, and then Jessi joins the show to show off Sandy the sand boa!

During peak thunderstorm season, Lake Maracaibo has an average of 28 lightning strikes per minute hit its surface. But why?

You might have heard that Earth is due for a complete flip of its magnetic field. And while our planet does have a history of this behavior, predictions of when it might happen are too complex to estimate a date for.

You just wanted to shuffle across the room in your pajamas and bunny slippers, but when you go to reach for the door knob... you get shocked! What gives!? What causes this strange effect?

In this video Paul Andersen explains how waves interact when moving through one another. Unlike particles waves can interfere both constructively and destructively. The amount of interference is determined through the superposition...

Mister Brown and Squeaks take a look at some flowers and their pollinators, and learn about special structures that help them work together perfectly!

In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized...

Potatoes are amazing! You can make them into french fries, baked potatoes, hash browns, potato chips, and tons of other tasty foods! And best of all, they're super easy to grow! Join Jessi and Squeaks to learn how!

Have you ever wondered why we wear clothes? I mean, beyond the obvious. Why does wearing a jacket in the cold keep your warmer? What is happening to all the heat inside your body? In this episode of Crash Course Physics, Shini talks...

Why does fire burn? What's the chemistry and physics of a flame? This week, learn about the beautiful science happening inside a flame!
