Electric Charge
In this video Paul Andersen introduces electric charge. Electric charge has been studies by humans and was generalized by scientists such as Benjamin Franklin. The amount of charge in a system is conserved but individual charges can move...

Jennifer Vail: The science of friction -- and its surprising impact on our lives
Tribology: it's a funny-sounding word you might not have heard before, but it could change how you see and interact with the physical world, says mechanical engineer Jennifer Vail. Offering lessons from tribology -- the study of friction...

Check Out the Satellites!
You might not know it, but there are thousands of human-made satellites orbiting the Earth! They help us do everything from study the climate to make phone calls, and there are even some satellites that people can live on!

Does The Moon Really Orbit The Earth?
According to Newton's law of gravitation, the sun should "pull" way harder on the moon than the Earth does. So does the moon actually orbit the Earth? Why?

Doppler Effect
In this video Paul Andersen explains how the perceived frequency of a source depends on the motion of both the source and the observer. As a source approaches an observer the frequency will increase and as it moves away it will decrease....

Relativistic Addition of Velocity | Special Relativity Ch. 6
This video is chapter 6 in my series on special relativity, and it covers the topic of relativistic addition of velocity: aka, how things that are moving relative to one inertial reference frame, which is moving relative to another...

TED-ED: How fast are you moving right now? - Tucker Hiatt
"How fast are you moving?" seems like an easy question, but it's actually quite complicated -- and perhaps best answered by another question: "Relative to what?" Even when you think you're standing still, the Earth is moving relative to...

Sound: Crash Course Physics
We learn a lot about our surroundings thanks to sound. But... what is it exactly? Sound, that is. What is sound? And how does it travel? And what is this Doppler Effect that we've heard so much about? In this episode of Crash Course...

Spacetime
In this video Paul Andersen explains how the dimensions of space and time are combined in relativistic mechanics. Gravity and velocity can affect both space and time according to Albert Einstein's Special Law of Relativity.

TED: What happens in your brain when you pay attention? | Mehdi Ordikhani-Seyedlar
Attention isn't just about what we focus on -- it's also about what our brains filter out. By investigating patterns in the brain as people try to focus, computational neuroscientist Mehdi Ordikhani-Seyedlar hopes to build computer...

Why Do Our Eyes Move When We Think?
You might have heard the myth that you can tell when someone is lying based on how their eyes move. While that is not exactly true, there has been plenty of science that looks into where and how we look when we think.

Using Sunlight to Propel Spaceships
When scientists are planning missions, they sometimes have to take into account the fact that the light from the Sun pushes on the spacecraft. But with solar sails, they can also use that pressure to propel the craft along.
