Rotterdam designer David Derksen has decorated a set of plates by employing the oscillations of a pendulum to drip patterns of paint (+ movie). The patterns on Derksen's prototype Oscillation Plates ...

A physical pendulum undergoes simple harmonic motion when displaced by a small angle. The oscillations are no longer simple harmonic motion when it is released from a large angle. The pendulum's pivot ...

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 ...
