  "etymology_text": "Coined by Paul Ehrenfest in 1911 in German. From the explosion of energy at the ultraviolet end of the spectrum (away from visible and infrared light) caused by the Rayleigh-Jeans Law theory. The use of UV is to represent that end of the spectrum, given that the visible spectrum represents a stand-in for the whole electromagnetic spectrum, and infrared and ultraviolet are stand-ins for the endpoints. This usage is similar to that represented by the logic behind the terms \"redshift\" and \"blueshift\", which assume endpoints of red and blue.",
