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 ...

A clever mathematical tool known as virtual particles unlocks the strange and mysterious inner workings of subatomic ...

Physics has a bit of a messy problem: There's matter missing in our universe. Something is there that we can't see, but scientists can detect. "When we look at how stars move in galaxies, they move as ...

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 ...

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 ...
