Revolutionary inventor, physicist, engineer, and futurist Nikola Tesla said, “If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.” And influential mathematician and philosopher Pythagoras said, “There is geometry in the humming of the strings, there is music in the spacing of the spheres.”
Turns out both visionaries were right. In fact, the amazing Chladni plate experiment captured in the video below clearly proves the relationship between frequency, tone, and geometry in a profound and beautiful way you won’t soon forget. Get ready to be blown away!
The experimenters used a tone generator, a wave driver (speaker) and a metal plate attached to the speaker. First, they added sand to the plate then began playing a tone. Certain frequencies vibrate the metal plate in such a way that it creates areas where there is no vibration. The sand “falls” into those areas, creating beautiful geometric patterns. As the frequency increases in pitch, the patterns become more complex.

Here is the full experiment for your wonderment. Warning: lower your volume before viewing the following video as the tones are quite loud. Enjoy:
