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 ...

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 ...

Researchers have designed a quantum version of a pendulum clock. It could shed light on timekeeping in the quantum realm ...

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 ...

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 ...
