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 ...

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 ...

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, ...

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 ...

[Stephen Hobley] has been experimenting with an electromagnetic pendulum in order to build himself a clock. Through the course of his experiments, he has learned quite a bit about how pendulums ...

175 years ago, the Foucault pendulum experiment caused a nationwide public science fad. Most people understood what scientists knew about the universe, but Foucault made it feel real. Science was ...

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 ...
