Right now, invisible signals are flying through the air all around you. Massive radio waves carry information between computers, GPS systems, cell phones, and more. And the sky is flooded with interference from routers, satellites, and,...

One Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in one minute!

Part of being very far away from the rest of the universe is that the signals are very faint, so sometimes you need a nice, quiet spot to listen from.

In this video Paul Andersen explains how the location of matter can be determined at the nanoscale using the wave function. The absolute value of the wave function can be used to determine the probability of finding matter in a...

Whether you've got the latest iPhone or the same flip phone you've had since 2002, you're still asked to turn off your device before take off. Why is that?

In this REALLY IMPORTANT EPISODE of Crash Course Psychology, Hank talks about how we remember and forget things, why our memories are fallible, and the dangers that can pose.

In this video Paul Andersen explains how matter can act as a wave at the nanoscale. Louis de Broglie showed that the wavelength of matter can be calculated using the momentum of an object and Planck's constant. The Davisson-Germer...

Pet trackers, and lots of other electronics, have little cylinders inside them called ferrite beads. If they didn't, they'd probably be picking up the local traffic report instead.

You might have realized that lots of ground-based telescopes are located in Hawaii...but why? It's not just for the beautiful sunsets.

What’s with all the "G"s and why do we keep having to develop new ones to use our phones in this technology.

The task sounds like it should be pretty easy, but the Stroop task is a fantastic, and very well studied, example of how your brain’s automatic processing can trip you up!

Can we accurately describe light as exclusively a wave or just a particle? Are the two mutually exclusive? In this third part of his series on light and color, Colm Kelleher discusses wave-particle duality and its relationship to how we...

In this video Paul Andersen explains how traveling waves move through space and time. The reflection and interference of traveling waves can create standing waves which appear motionless. Examples of traveling waves in one and two...

In this video Paul Andersen explains how beats are created through interference of waves with similar frequencies. The changes in amplitude are caused by destructive and constructive interference. The frequency of beats is equal to the...

In this video Paul Andersen explains how light can be treated as both a particle and a wave. Physicists use scale to determine which model to use when studying light. When the wavelength of light is equivalent to the size of the object...

The way light behaves can seem very counter intuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense! In this episode of Crash Course Physics, Shini shows us how we know...

In this video Paul Andersen explains how waves interact with objects and with other waves. When a wave hits a fixed object it will be reflected and inverted. When a wave hits a free object it will be reflected without being inverted. ...

In this video Paul Andersen explains how constructive and destructive interference can create interference patterns. Interference patterns can be created by all types of waves, including water, sound, and light. A classic experiment...

Light is everywhere … but it’s not as predictable as you might think. It’s a wave that travels in straight lines, yet it also reflects off of surfaces, refracts through various materials, and generally changes direction all the time!...
