Ultraviolet Rays Quotes & Sayings

The past has a future, something it becomes, and that transforms it. Like the facts themselves, the person, the "I", who experiences it and looks back on it discovers that it is not singular, but plural. Traveling through those places marked down in those epic chronicles of thirty years ago, one gets the impression of slicing through paper-thin, invisible barriers, different levels of reality, still present and with us even though not discernible to the naked eye, infrared or ultraviolet rays of history, images and instants that at this point cannot print an image on the celluloid, but which nonetheless are, and exist in the same way for tangible experience as electrons which elude our grasp. — Claudio Magris

Just as the spectrums of light and sound are far broader than what we humans can see and hear, so the spectrum of mental states is far larger than what the average human perceives. We can see light in wavelengths of between 400 and 700 nanometres only. Above this small principality of human vision extend the unseen but vast realms of infrared, microwaves and radio waves, and below it lie the dark dominions of ultraviolet, X-rays and gamma rays. Similarly, the spectrum of possible mental states may be infinite, but science has studied only two tiny sections of it: the sub-normative and the WEIRD. For — Yuval Noah Harari

connection between skin color and sunlight. The results were as clear as the sky on a cloudless day - there was a near-constant correlation between skin color and sunlight exposure in populations that had remained in the same area for 500 years or more. They even produced an equation to express the relationship between a given population's skin color and its annual exposure to ultraviolet rays. (If you're feeling adventurous, the equation is W = 70-AUV/10. W represents relative whiteness and AUV represents annual ultraviolet exposure. The 70 is based on research that indicates that the whitest possible skin - the result of a population that received zero exposure to UV - would reflect about 70 percent of the light directed at it.) — Sharon Moalem

Like ultraviolet rays memory shows to each man in the book of life a script that invisibly and prophetically glosses the text. — Walter Benjamin

The entire electromagnetic spectrum - from radar to TV, infrared light, visible light, ultraviolet light, X-rays, microwaves, and gamma rays - is nothing but Maxwell waves, which in turn are vibrating Faraday force fields. — Michio Kaku

An atmosphere ultraviolet rays from the sun, even from a weak sun, would have tended to break apart any incipient bonds made by molecules. And yet right there" - she tapped the stromatolites - "you have organisms almost at the surface. It's a puzzle. — Bill Bryson
