Ernst Chladni documented the frequency patterns created in sand as it conforms to the sound frequencies emitted from vibrating metallic plates, he developed a formula that connected the specific frequencies with their manifest patterns, and published the results in his 1787 treatise. His work became an essential tool for violin and other musical instrument makers, and after publishing his 1802 book, Die Akustik, Chladni earned the title, “father of acoustics,” and his work became known as Cymatics. An incredible study that was hardly known of until the 1990s, when it began to spread on the internet and be demonstrated in videos. A century before Chladni, in 1680, Robert Hooke applied sand to a solid metal plate and ran a violin bow across the edge to create a vibration. Depending on the frequency he played, specific patterns would form in the sand. A century before that, Galileo observed the same thing with small particles on a musical sounding-board. A century before that, Leonardo da Vinci noted that distinct patterns would form within particles when subjected to vibration. And before da Vinci, the Rosslyn Chapel was founded in 1446 near Edinburgh, Scotland. A mysterious work of art with a very storied past. One of the oldest stories is that the chapel’s master mason was commissioned to carve a pillar but felt the need to travel Europe on holiday for inspiration. While away, his apprentice had a vision and carved the column on his own. When the master mason returned, he found the completed pillar to be a masterpiece, which triggered him into a violent fit of jealous rage. He struck his apprentice on the head, crushed his skull and killed him. There is a popular myth that a small group of the Knights Templar fled persecution in the 14th century and hid the Ark of the…
