At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow. Scientists in Amsterdam have found that this same kind of behavior happens at a ...

Sometimes you think you have a complete understanding of something and then BOOM—a simple problem throws everything out the window. Let's consider a very basic physics problem involving pushing a ...

Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects - particularly in wet ...

Because of friction, sleds don't technically touch the snow and instead ride on a small layer of water created by the heat of the sled sliding down the hill. Sledding is one of many ways Wisconsinites ...

Neely Myers, Executive Director for the Schroeder Family Exploreum brings two athletes from the Joplin Eagles Football team to demonstrate the power of friction. 26,706 people played the daily ...

Charging from friction. Flexoelectricity and tribology may explain how. Credit: Laurence Marks/Northwestern University The electric shock you get from shuffling along a carpet might be the first ...

Memory fault: friction study could provide new insights into why earthquakes happen. (Courtesy: iStock/allanswort) Experiments by Sam Dillavou and Shmuel Rubinstein at Harvard University have, for the ...

I learned to respect friction, as a phenomenon with many nuances, when I was a graduate student. One day, while teaching a problem session in elementary mechanics, I unwisely invented a new problem to ...

MIT scientists have coaxed atoms into an exotic “edge state” for the first time, allowing them to flow completely friction-free. The breakthrough could lead to better superconductor materials. As ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...
