Vibrations in the real world
Of course, you don’t believe in all the new age stuff with vibrations and all, don’t you ?
So, let’s introduce you to the visible part of it:
Exhibit #1: water and sound experiment:

What is nice, is that you can build it yourself (almost easily):
a speaker
a water hose connected to a water supply
tone generating equipment
a 24 frames-per-second camera
Exhibit #2: the resonance experiment
This one starts with a quote from Nikola Tesla:
If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.
and is a very visually beautiful experiment:

I would like to give credit to friend PHA who has pointed me into the direction of Douglas Hofstadter’s book Metamagical Themas.
