At the Houston Museum of Natural Science they recently made a disturbing discovery: their Foucault pendulum had stopped swinging for the first time since its installation in the 1970s. (Video, ...

A basic pendulum is a mass at the end of a string that swings back and forth. It seems simple, and it appears in most introductory physics textbooks. But it's not a trivial problem to solve for the ...

The new device will still have the same size as the original Digimon Pendulum, but it will come with a lot of new features. Other than full-colored sprites, the device will have an internal battery ...

Check out Dr. Bob Grober on YouTube. I heard the term “harmonic oscillator” a few years ago and was lost until I found out it was simply a pendulum. Understanding how a pendulum works and how we can ...

This post has been sitting in my mind for quite some time. Really, it is about mechanics - not about pendulums. What is the goal in mechanics (classical mechanics, if you like)? Generally, it is to ...

Top 100 Teacher Erika Larkin explains the “pendulum” technique that will improve low-point control, consistency and contact.

As a rule, Donald Saff doesn’t collect clocks he can’t see inside of. It’s the harmonic entanglement of gears—and the skill needed to craft them—that first lured him to horology, the study 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 ...

Reaction wheels are useful things, typically used by satellites to keep themselves oriented the right way up in space. Turning the reaction wheel creates an equal and opposite torque in the spacecraft ...
