So, Negative Gravity Is a Thing
In nature, most of our basic forces both attract and repel. In fact, gravity is the only exception. But, according to theorists, sound waves actually have negative gravity.

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.

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...

Hardy's Paradox | Quantum Double Double Slit Experiment
This video is about Hardy's Paradox, wherein an electron and positron (or photons polarized horizontally and vertically) pass through Mach-Zehnder interferometers that overlap such that the particles have a chance of annihilating. If...
