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 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 ...

The authors present an elementary scheme for calculating the period of oscillation or rotation of a simple pendulum. It is based on the invariance of the complete elliptic integral of the first under ...

THE oscillations of a long pendulum are observed to describe an ellipse the axis of which tends to set itself at right-angles to the plane in which the pendulum was started. An explanation of the ...

A Foucault pendulum, or Foucault's pendulum, named after the French physicist Leon Foucault, was conceived as an experiment to demonstrate the rotation of the Earth; its action is a result of the ...
