In this video, we break down the physics behind clay pendulum balls and their collisions. Learn about momentum, energy transfer, and how these simple systems can explain key concepts in ...

At the Houston Museum of Natural Science they recently made a disturbing discovery: their Foucault pendulum had stopped ...

This is a requested post. Clearly, I do requests. The idea here is that I am going to give all the details needed to determine the equation of motion (and then model it) for a basic pendulum. Warning: ...

The first Foucault’s pendulum I ever saw was at the Franklin Institute in Philadelphia, the city where I was born. The pendulum hung in a stairwell. Its wire was attached to the ceiling four stories ...

For the first time, researchers have measured the lifetime of an excited state in the nucleus of an unstable element. This is a major step toward a nuclear clock that could keep even better time than ...

Next month a total solar eclipse will be seen across the United States. It is one of the few eclipses to trace a path through several densely populated areas, and that means there's plenty of ...

In the 17th century, Christiaan Huygens, inventor of the pendulum clock, noticed a curious phenomenon. When two identical pendulum clocks are mounted next to each other on a wall, their swings ...
