Turn off unnecessary lights outdoors and replace outdoor lights with low-glare versions. The International Dark-Sky Association certifies lights for low-glare and efficiency, and the company Starry Night Lights produces low light pollution lighting that is more environmentally-friendly. In this verse, the statement that the Lord “stretched out the heavens” is paired with the statement that He “laid the foundations of the earth.” Since the latter act is certainly to be understood as an action completed in the past, the former should be as well. Thus, it is most likely that this past stretching is related to creation. I propose that the stretching of the heavens may refer to rapid stretching of space to get starlight to the earth on Day Four, the same day that stars were made.

In developing nations, acute respiratory infection, influenza and pneumonia kill nearly two million children annually. The light fixtures in our homes are remarkably effective and may work for years with little attention other than replacing an occasional burned-out light bulb. Sometimes, though, a light fixture that’s been working fine may suddenly develop a problem that requires diagnosis and repair. The correction can be very simple—such as replacing the light bulb or adjusting the light bulb socket—or as complex as replacing the entire light fixture or a wall switch. Some studies suggest a link between exposure to light at night, such as working the night shift, to some types of cancer, diabetes, heart disease, and obesity. That’s not proof that nighttime light exposure causes these conditions; nor is it clear why it could be bad for us. But we do know that exposure to light suppresses the secretion of melatonin, a hormone that influences circadian rhythms, and there’s some experimental evidence (it’s very preliminary) that lower melatonin levels might explain the association with cancer. In certain cases an over-illumination lighting technique may be needed. For example, indirect lighting is often used to obtain a “softer” look, since hard direct lighting is generally found less desirable for certain surfaces, such as skin. The indirect lighting method is perceived as more cozy and suits bars, restaurants and living quarters. It is also possible to block the direct lighting effect by adding softening filters or other solutions, though intensity will be reduced. The physics of fluorescent lights can’t be changed, but coatings inside the bulbs can be so they produce a warmer, less blue light. LED lights are more efficient than fluorescent lights, but they also produce a fair amount of light in the blue spectrum. Richard Hansler, a light researcher at John Carroll University in Cleveland, notes that ordinary incandescent lights also produce some blue light, although less than most fluorescent lightbulbs. The blinding effect is caused in large part by reduced contrast due to light scattering in the eye by excessive brightness, or to reflection of light from dark areas in the field of vision, with luminance similar to the background luminance. This kind of glare is a particular instance of disability glare, called veiling glare. (This is not the same as loss of accommodation of night vision which is caused by the direct effect of the light itself on the eye.) Kerosene lamps produce carbon dioxide (CO2). It is estimated that each kerosene lantern with a weekly fuel consumption of one litre of kerosene produces 0.1 tonnes of CO2 each year. In general, fuel-based lighting in the developing world is a source of 244 million tons of CO2 emissions to the atmosphere each year. This amounts to 58% of the CO2 emissions from residential electric lighting. If blue light does have adverse health effects, then environmental concerns, and the quest for energy-efficient lighting, could be at odds with personal health. Those curlicue compact fluorescent lightbulbs and LED lights are much more energy-efficient than the old-fashioned incandescent lightbulbs we grew up with. But they also tend to produce more blue light. Report a street light problem To solve the starlight problem, some creationists have proposed a change in the speed of light; this proposition became known as c-decay. The idea was first systematically advanced by creationist Barry Setterfield in his 1981 book The Velocity of Light and the Age of the Universe. Setterfield claimed that, at the date of creation, light traveled millions of times faster than it does today and has been decaying precipitously ever since (until it stopped at its present value coincidentally with the ability to detect small changes). This idea is fundamentally absurd and since its inception has been universally derided by scientists. The idea was supported into the late eighties by creationists whose claims became more and more bizarre in attempts to prop up their failing model, until it finally collapsed under the weight of the evidence against it. In 1988, the idea was given up by the major creationist organization Institute for Creation Research, which, in an attempt to distance themselves from the scientific debacle that c-decay had become, became vocal critics of it.[5] The use of full cutoff fixtures can allow for lower wattage lamps to be used in the fixtures, producing the same or sometimes a better effect, due to being more carefully controlled. In every lighting system, some sky glow also results from light reflected from the ground. This reflection can be reduced, however, by being careful to use only the lowest wattage necessary for the lamp, and setting spacing between lights appropriately.[86] Assuring luminaire setback is greater than 90° from highly reflective surfaces also diminishes reflectance. Call it the most misunderstood indicator on your dashboard: The check engine light can mean many different things, from a loose gas cap to a seriously misfiring engine. I’m so worried about my camera right now I just dropped it and now the red light isn’t going away I don’t know what to do PLEASE HELP The Bluebird Library has been celebrating the lives of famous scientists. Each month, a new scientist is selected and displays are created to feature the discoveries and contribution of the scientist. April’s scientist of the month is Thomas Young; the library wishes to develop a Young’s experient display. The library has purchased a blue laser which emits light with a wavelength of 473 nm. They also have purchased a slide with a double slit; the slit spacing is 44 µm. The library’s current plans are to project the interference pattern onto a white board which is 3 feet wide and located 28 feet from the slits. What is the maximum number of bright spots which will appear on the board at these distances and what is the spacing distance between each bright spot? Assume that each bright spot is bright enough to see. (GIVEN: 1 m = 3.28 ft, 1 m = 106 mm, 1 m = 109 nm) Check out the FAQ for commonly asked questions about The City street lighting program. Sea turtle hatchlings emerging from nests on beaches are another casualty of light pollution. It is a common misconception that hatchling sea turtles are attracted to the moon. Rather, they find the ocean by moving away from the dark silhouette of dunes and their vegetation, a behavior with which artificial lights interfere.[67] The breeding activity and reproductive phenology of toads, however, are cued by moonlight.[68] Juvenile seabirds may also be disoriented by lights as they leave their nests and fly out to sea.[69][70][71] Amphibians and reptiles are also affected by light pollution. Introduced light sources during normally dark periods can disrupt levels of melatonin production. Melatonin is a hormone that regulates photoperiodic physiology and behaviour. Some species of frogs and salamanders utilize a light-dependent “compass” to orient their migratory behaviour to breeding sites. Introduced light can also cause developmental irregularities, such as retinal damage, reduced sperm production, and genetic mutation.[53][72][73][58][74][75] xtrasize TestX Core Atlant Gel erogran sterydy BioBelt vigrx power up premium Zevs power up premium
