The world has a titanic problem with disposing of plastic bags. Literally. Floating in the midst of the Pacific Ocean is a double-vortex of garbage that stretches from the west coast of the United States to the Islands of Japan. The Great Pacific Garbage Patch is composed six thousand three hundred and twenty-one miles of trash. The majority of this artificial waste continent is discarded fishing nets‚ plastic water bottles and caps‚ and plastic bags. Obviously‚ garbage in the vast expanse of the

What is Light Pollution? Light Pollution Light pollution is artificial or outdoor light that creates glare and intrudes with the nighttime setting and the natural night environment. The artificial light that is produced by urban centres/ areas‚ diminish the view of stars and planets. These artificial lights can be seen all the way out in space! Satellite images show light pollution as well lit and glowing regions on a map at nighttime (see image below). These well-lit regions are mostly cities

At the candle light I declare after all there is no enjoyment like reading! How much sooner one tires of a thing than of a book! -- When I have a house of my own‚ I shall be miserable if I have not an excellent library.” ― Jane Austen‚ Pride and Prejudice In a world that believes ignorance is bliss‚ true knowledge can only be earned by reading.

can go green. 1. Save energy to save money. * Set your thermostat a few degrees lower in the winter and a few degrees higher in the summer to save on heating and cooling costs. * Install compact fluorescent light bulbs (CFLs) when your older incandescent bulbs burn out. * Unplug appliances when you’re not using them. Or‚ use a "smart" power strip that senses when appliances are off and cuts "phantom" or "vampire" energy use. * Wash clothes in cold water whenever possible

Light pollution Light pollution‚ also known as photo pollution or luminous pollution‚ is excessive artificial light. This phenomenon is pronounced around urban centers‚ where city lights diminish the view of stars and planets. In addition to brightened skies around cities‚ light pollution also refers to any outdoor light that creates glare and interferes with the natural night environment. Cause Light pollution results from outdoor lights aimed

THE NATURE OF LIGHT Until the time of Isaac Newton (1642–1727)‚ most scientists thought that light consisted of streams of particles (called corpuscles) emitted by light sources. Galileo and others tried (unsuccessfully) to measure the speed of light. Around 1665‚ evidence of wave properties of light began to be discovered. By the early 19th century‚ evidence that light is a wave had grown very persuasive. In 1873‚ James Clerk Maxwell predicted the existence of electromagnetic waves and calculated

Silverstein PHY 101 Section 10497 March 4‚ 2013 Light up this World Purpose: In this lab experiment‚ LED lights will be used to show how when E&M radiation is absorbed‚ the energy is converted to heat. A drop of isopropyl alcohol will absorb light energy of different colors‚ and the evaporation rate of the alcohol will be measured. The key to this lab is the evaporation rate is directly related to the energy of the light shining on the drop. Materials: * * LEDs and circuits

Reflection Bobby Bottle was hopping to school through the meadow‚ he saw Mia Mirror standing outside. When he walked up to her‚ she noticed his cap was on tighter than usual. Then he spoke‚ “Mia why are you so stupid‚ couldn’t you just be more smart!” Mia looked at him‚ her eyes grew glassier than normal. “Oh.” was all she said and walked away. Mia went into class. “Good morning Mia.” said Mrs.Olivia Owl. Mia didn’t respond and sulked past her. “Guess what!” said Freya Fish‚ walking up to Mia

2-8 Refraction and polarization of light 5. Experiment Results A. Linearity of light 1. The light beam does go straight when we tested on the angle board. 2. As the source of light beam was getting farther away from the slit‚ the beam becomes narrower and shorter in addition to fading. This is because light particles escape more when they travel to go through the slit. B. Law of reflection Angle of incidence is the angle formed by a ray incident on a surface
