Tsunamis... From the Sky?
Scientists have developed reliable early warning systems for tsunamis caused by earthquakes. The problem is, earthquakes aren't the only things that cause tsunamis.

Rogue Waves
For a long time, rogue waves (defined as waves that are greater than twice the height of surrounding waves) were thought to be a myth, like mermaids or the kraken, but recent developments in satellite imagery and oceanic instruments now...

Wave Energy
In this video Paul Andersen explains how the energy of a wave if directly related to the amplitude of a wave. The wave energy of a sound wave is the volume of the wave.

5 Measurements You Might Not Realize Are Named After Scientists
Units are a major way we describe the world around us, and by looking at the scientists some of them are named after, we can get a sense of how we’ve learned so much about our universe.

Wave-Particle Duality - Part 2
In this video Paul Andersen explains how classical waves (like light) can have particle properties. Albert Einsetein used the photoelectric effect to show how photons have particle properties.

Maxwell's Equations: Crash Course Physics
In the early 1800s, Michael Faraday showed us how a changing magnetic field induces an electromotive force, or emf, resulting in an electric current. He also found that electric fields sometimes act like magnetic fields, and developed...

Wave Speed
In this video Paul Andersen explains how the wave speed measure the speed of a wave through a medium. The medium determines the speed of the wave. The velocity of the wave is equal to the product of the wavelength and the frequency of...

TED-Ed: How to squeeze electricity out of crystals - Ashwini Bharathula
It might sound like science fiction, but if you press on a crystal of sugar, it will actually generate its own electricity. This simple crystal can act like a tiny power source because sugar happens to be piezoelectric. Ashwini...

Photons
In this video Paul Andersen explains how light travels in photons which can be described as both particles and waves. Einstein showed that photons can be described as particles using the photoelectric effect to show that the energy of a...

TED-Ed: What is the Heisenberg Uncertainty Principle? - Chad Orzel
The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Why not? Because everything in the universe behaves like both a particle and a wave at the same time....
