What does it mean to you?
I'm curious why 1 synodic earth day is assigned a frequency of 194.18 Hz, a color of red-orange, and a tempo of 91.9 bpm.
Also curious why there would be any equivalence between sound waves, motions of air molecules, vibrating at let's say 440 Hz (standard A4) which this chart assigns a sapphire color, and a portion of the electromagnetic spectrum of visible light at wavelength circa 450 nm.
Is the assignment arbitrary, or is there some explanation for it?
