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 century after Einstein predicted the outcome from a black hole collision, Frans Pretorius helped pave the way for the actual discovery of the ripples that would expand our understanding of the ...

Random conditions in the ocean occasionally produce mammoth waves. A wave must be at least 2.2 times the height of the so-called significant wave height to qualify as a freak wave. The significant ...

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 ...
