scottos Posted June 10, 2013 Posted June 10, 2013 Just saw this an it reminded me an awful lot if a certain scene with Kabsul. Didn't know it was a real thing. 2
Shardlet he/him Posted June 10, 2013 Posted June 10, 2013 (edited) It is a depiction of an effect discovered by http://en.wikipedia.org/wiki/Ernst_Chladni'>Ernst Chladni. In his original work and presentation of the effect, Chladni used a bow for an instrument such as a violin to generate the frequencies that created the patterns on the plate. Cool find SR! Edit: Here is some more: http://en.wikipedia.org/wiki/Cymatics'>Cymatics is a real world term. Galileo was the first known person to discover the effect (~1632) when he scraped a chisel on a brass plate to remove spots on the plate and noticed the formation of parallel equidistant lines of crud forming. Robert Hooke conducted similar experiments (1680) with a glass plate and a violin bow. But, Chladni (pronouned Klawdnee) what the first to describe the effect on metal plates with an instrument bow (1787). The term 'cymatics' was coined by Swiss medical doctor and Anthroposophist, Hans Jenny in 1967. Edited June 10, 2013 by Shardlet
scottos Posted June 10, 2013 Author Posted June 10, 2013 Yeah it's pretty cool, when I read that section in the book I thought something like this sounds like it would actually work in real life. Brandon never ceases to amaze me with the subtle details he puts into his books! And thanks Shardlet, for that like on Ernst Chladni!
happyman he/him Posted June 11, 2013 Posted June 11, 2013 Oh, that trick? I've seen stunts like that pulled in anechoic chambers a few times. The key point is that when you get a standing wave on a surface, some parts move and some parts stay put, according to the geometry of the surface. Any sand or other materials on the surface gets bounced off the moving parts, accumulating on the still parts. About all Kabsal's little demonstration proves is that the dawn-cities were created by some sort of standing wave in a two-dimensional geometry. Actually, it doesn't even prove that; the symmetries that the sound obeys might be obeyed by other things as well. But the patterns are quite pretty.
Phantom Monstrosity Posted June 11, 2013 Posted June 11, 2013 (edited) If you haven't looked up the Rosslyn Motet, it's a pretty funny conspiracy theory involving these patterns. Anyway... is it possible that the cryptic headlines are the same as these patterns? Edited June 13, 2013 by Phantom Monstrosity
