Ring my string: Building silicon nano-strings
Tightening a string, e.g. when tuning a guitar, makes it vibrate faster. But when strings are nano-sized, increased tension also reduces, or 'dilutes', the loss of the string's vibrational modes.

The world we experience is governed by classical physics. How we move, where we are, and how fast we're going are all determined by the classical assumption that we can only exist in one place at any one moment in time.
