Researchers at Tampere University and the University of Eastern Finland have reached a milestone in a study where they derived a new kind of wave equation, which applies for accelerating waves. The ...

Whenever light interacts with matter, light appears to slow down. This is not a new observation and standard wave mechanics can describe most of these daily phenomena. For example, when light is ...

This is a classic introductory physics problem. Basically, you have a cart on a frictionless track (call this m 1) with a string that runs over a pulley to another mass hanging below (call this m 2).

Quantum physics tells us about the properties and behaviors of atomic and subatomic particles. But scientists have long held the belief that the rules that govern the microscopic world should also be ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Our standard model of elementary particles and forces has recently become as close to “complete” as we could conceivably ask for. Every single one of the elementary particles — in all their different ...
