I remember gazing at the stars with my mom when I was a kid. She pointed out the Milky Way and a number of constellations. She told me, “there are way too many stars to count!” Now, 50 years later, when I walk outside and look up, I see only a few identifiable constellations, no Milky Way, and I would venture to say there were so few stars that if I took a little time, I could count them all. Are there really fewer stars in the heavens? Not at all. The stars are up there, they just cannot be seen by the naked eye from the vast majority of heavily populated vantage points anymore. The culprit, I learned, is called “Light Pollution”.
According to the International Dark-Sky Association (IDA), light pollution is “the unnatural luminescence created by a combination of urban sky glow, glare and light trespass” (Petersen). What that means is that the artificial lighting of nighttime hours has created a bright halo, or “glow”, over urban and some rural areas, eliminating the natural state of total darkness. The “glare” refers to horizontal light that shines directly into one’s eyes. “Light trespass” involves unwanted artificial light spilling onto and into property (from floodlights, security lights, street lights) that would otherwise be dark (IDA). Astronomers were the first to notice this problem 30 years ago when they became frustrated as sky glow began impairing their ability to see the stars (Bower).
Since Thomas Edison's invention of the incandescent light bulb in 1879, people have been lighting up the night in ever-increasing ways and intensities. As a result of this human-manufactured illumination, in her article, Our Vanishing Night, Verlyn Klinkenborg shares, “In most cities, the sky looks as thoug...

- It happens more often than not- waking in the middle of the night. As I become conscious of my surroundings, I am filled with a sense of foreboding. The soft hisses and puffs escaping my loved ones lips while deep in the throes of sleep provide the only distraction from the all-encompassing silence. As I strain to hear the sounds of life surrounding me the ominous sensation of being alone, abandoned, is ignited within me. It feels as if my loved one have left and gone to somewhere that I am no longer welcomed and I must stay behind, long forgotten.... [tags: night,]

- Having electricity is something that most people feel they need to be comfortable and safe in their day to day lives. So much so, that the demand for lighting has increased rapidly over the years. This increase in demand also includes the usage of artificial lighting which also contributes greatly to light pollution. Light pollution has had an unfavorable effect on the planet and this includes humans, animals, and plants as a whole. Light pollution is the “inappropriate or excessive usage of light causing glare, sky glow, and light trespass”.... [tags: Light pollution, Lighting, Light]

- The darkness of the night, the light of the moon; these are the metaphors of the brain. The darkness refers to all of the negative experiences and stress the brain endures. While the moon light refers to the experiences we love to undergo and pray they never cease. No one can choose what things their brain can reject and take in. If that were the case we wouldn’t have the need for psychologist and social workers and others in this line of work. The Perks of Being a Wallflower is a coming of age film that exhibits these roller coaster characteristics of how the brain can be in an individual....

- Our perception of the world is dependent on our senses and response to stimulus. Sensation is the process of absorbing energy from a physical stimulus in the environment and converting this energy into neural impulses and sending them to the brain. The brain then interprets and organises this sensory information resulting in our subjective conscious experience or perception. (Lefton & Brannon 2003) The five human sensory organs receive the stimulus which determines our perception. Arguably the most important of these senses is vision....

- Making a Night Light A nightlight provides light at the change of the light- mostly at night. The definition of light night is so that night passers will be able to see more clearly, drivers will be able to drive safely and accidents will be avoided. Nightlight requires LDR (Light Dependent Resistor). The resistor changes its resistance depending on the amount of light it receives. LDR is also used to monitor light intensity level. A resistor, which reduces the flow of current in circuit, is also needed.... [tags: Papers]
