Wave-Particle Duality of Light
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 a...

Einstein's Revolution: Crash Course History of Science
There was physics before Einstein in the same way that there was biology before Darwin. Einstein didn’t just add some new ideas to physics. And he didn’t just add a unifying framework for doing physics, like Newton. Einstein took what...

Matter as a Particle
In this video Paul Andersen explains how matter, like light, can be treated as both a particle and a wave. Louis de Broglie proposed that matter could act as a wave and described the wavelength of matter as a function of Planck's...

Why Is the Speed of Light Limited—and What If It Weren’t?
New ReviewWhy does the universe have an upper speed limit on the speed of light? Why isn’t the top limit infinite? Or what if the speed of light was not constant but changed in different reference frames? The speed of light is dependent on two...

Could Dark Matter Be an Illusion? Exploring the Case for MOND
Is it possible that what we have invented as dark matter to explain the motion of stars in galaxies and clusters is a figment of our imagination? Could it be that Einstein’s General Relativity has a flaw? Does dark matter exist? Vera...
