Ultraviolet Light Quotes & Sayings

I'm the soft light compared to their ultraviolet. — Calla Devlin

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

The scale of light can be described by numbers called the frequency and as the numbers get higher, the light goes from red to blue to ultraviolet. We can't see ultraviolet light, but it can affect photographic plates. It's still light only the number is different. — Richard P. Feynman

Giant hogweed is considered extremely dangerous because its sap, in combination with ultraviolet light, can burn human skin. Every year, millions are spent digging up plants and destroying them, without any great success. However, hogweed can spread only because the original forested meadows along the banks of rivers and streams no longer exist. If these forests were to return, it would be so dark under the forest canopy that hogweed would disappear. The same goes for Himalayan balsam and Japanese knotweed, which also grow on the riverbanks in the absence of the forests. Trees could solve the problem if people trying to improve things would only allow them to take over. — Peter Wohlleben

The takeaway message here, as Jablonski points out, is that there is no such thing as different races of humans. Any differences we traditionally associate with race are a product of our need for vitamin D and our relationship to the Sun. Just a few clusters of genes control skin color; the changes in skin color are recent; they've gone back and forth with migrations; they are not the same even among two groups with similarly dark skin; and they are tiny compared to the total human genome. So skin color and "race" are neither significant nor consistent defining traits. We all descended from the same African ancestors, with little genetic separation from each other. The different colors or tones of skin are the result of an evolutionary response to ultraviolet light in local environments. Everybody has brown skin tinted by the pigment melanin. Some people have light brown skin. Some people have dark brown skin. But we all are brown, brown, brown. — Bill Nye

For excellent health and a good skin color, I recommend that people sit next to a shady ultraviolet transmitting window when indoors. — Steven Magee

In the museums we used to visit on family vacations when I was a kid, I used to love those rooms which displayed collections of minerals in a kind of closet or chamber which would, at the push of a button, darken. Then ultraviolet lights would begin to glow and the minerals would seem to come alive, new colors, new possibilities, and architectures revealed. Plain stones became fantastic, "futuristic ... " Of course there wasn't any black light in the center of the earth, in the caves where they were quarried; how strange that these stones should have to be brought here, bathed with this unnatural light in order for their transcendent characters to emerge. Irradiation revealed a secret aspect of the world.
Imagine illness as this light; demanding, torturous, punitive, it nonetheless reveals more of what things are. A certain glow of being appears. I think this is what is meant when we speculate that death is what makes love possible. — Mark Doty

Like many insects, flies are most sensitive to green light. This means that they would see their world as 'black and white,' in that they can't see the multiple colors required to reconstruct a color image of the world. They do, however, have specialized cells that enable them to see ultraviolet wavelengths. — Michael Dickinson

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

They put on fresh gloves and got back to business. Jazz wiped up the blood splatters in the freezer and tossed the tissues in with Howie's waste. It bothered him that he was leaving evidence behind without some sort of oxygenated bleach, those blood splatters would still show up under Luminol. Of course, the odds of anyone deciding to spray down the morgue freezer and switch on an ultraviolet light were pretty minimal, so it's not like it was evidence that anyone would ever find or use. Still: Billy Dent's First Commandment was Thou shalt not leave evidence. — Barry Lyga

In the bathroom two water tumblers were sealed in cellophane sacks with the words: "These glasses are sterilized for your protection." Across the toilet seat a strip of paper bore the message: "This seat has been sterilized with ultraviolet light for your protection." Everyone was protecting me and it was horrible. — John Steinbeck

The unthinkable is that we're distorting this atmospheric balance. We're shifting the chemical balance so that we have more poisons in the atmosphere - ozones and acid rain on ground level - while we're also changing the thermal climate of the earth through the greenhouse effect and - get this - simultaneously causing destruction of our primary filter of ultraviolet light. It's incredible. Talk about the national-debt crisis - we're piling up debts in the atmosphere, and the piper will want to be paid. — Michael Oppenheimer

I've been wanting to tell people my theory about what goes on after time. It's beyond our consciousness. We get glimpses of it between the infrared and the ultraviolet - the narrow narrow corridor of light that we are able to perceive. — Russell Brand

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

Peeping through my keyhold I see within the range of only about 30 percent of the light that comes from the sun; the rest is infrared and some little ultraviolet, perfectly apparent to many animals, but invisible to me. A nightmare network of ganglia, charged and firing without my knowledge, cuts and splices what I see, editing it for my brain. Donald E. Carr points out that the sense impressions of one-celled animals are not edited for the brian: 'This is philosophically interesting in a rather mournful way, since it means that only the simplest animals perceive the universe as it is. — Annie Dillard
