As we learn more about electricity, we have to talk about fields. As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they're really fascinating ...

Interesting formations: an example of droplet shapes that are produced when an electric field is applied to an oil mixture. (Courtesy: Aalto University) When a simple system of two liquids is driven ...

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 ...

It is usually a good idea to keep water away from electrical equipment but researchers in Japan have discovered a new effect by breaking this rule. Masahide Gunji and Masao Washizu of the University ...

Electromagnetism is a simple example of a gauge theory where the underlying potentials (the vector and scalar potentials) are defined only up to a gauge choice. The vector potential generates magnetic ...

A central idea of physics is that reference frames don't change fundamental laws. It shouldn't matter where you observe an event or how fast you are moving, the laws of physics should remain the same ...

In 1832, Charles Darwin witnessed hundreds of ballooning spiders landing on the HMS Beagle while some 60 miles offshore. Ballooning is a phenomenon that's been known since at least the days of ...

Lightning has captivated scientists for centuries, but despite extensive research, the precise atmospheric conditions that trigger a lightning strike within thunderclouds have remained a profound ...

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

Math, specifically calculus, is a barrier to many natural sciences, technology and engineering fields. Physics, which is math-heavy, often proves similarly challenging to students who wish to pursue ...
