Imagine plucking a guitar string. It vibrates, the sound lingers, and then fades away as the energy drains into the air. Now bring this scene down to the scale of an atom. Can an atom vibrate in the ...

A plucked guitar string can vibrate for seconds before falling silent. A playground swing, emptied of its passenger, will gradually come to rest. These are what physicists call "damped harmonic ...

SIAM Journal on Applied Mathematics, Vol. 49, No. 2 (Apr., 1989), pp. 404-419 (16 pages) This paper considers the asymptotic behavior of the random harmonic oscillator driven by a Markov process with ...

A strong permanent magnet acts as a simple pendulum, swinging back and forth while hanging from strings. A copper plate underneath the magnet can be moved up to tune the eddy current damping. Swing ...
