Foucault’s pendulum experiment led to an increase in the public’s interest in both real-life science and science fiction.

In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in ...

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 ...

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, ...

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 ...

The answer is yes. Yes, you can get a value of pi using a pendulum. Well, you need a few other things. Of course, this is the experimental part of my previous post on the connection between pi and the ...

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 ...

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 ...
