That big grandfather clock in the library might be an impressive piece of mechanical ingenuity, and an even better example of fine cabinetry, but we’d expect that the accuracy of a pendulum timepiece ...

Engineer Tom Stanton, who also runs a YouTube channel with the same name, has ...

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 ...

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 ...

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 ...

During Foucalt’s life it was already proven that the Earth rotated, thanks to experiments which showed that weights dropped from tall towers fell slightly to one side rather than straight down. This ...
