ummary: Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Is there any person who comes to ON/OFF these lights? The following circuit that described below which perform this job automatically. This circuit employed the output from an uncomplicated light/dark activated circuit and oblige a relay in its output which can be further attached to switch ON/OFF a street light and electrical application in a household also. Many of the

Blue Gold This is a documentary about the ever increasing water crisis in our world today; what is causing it‚ the consequences‚ and how to stop it. Ecologists everywhere began to take notice of the “desertification” of our planet and the dire consequences ahead if it is not stopped. The urgency of this issue is one that cannot be brushed off because it is not us destroying solely the planet we live on‚ but destroying our chances of survival on it. Desertification of the earth is caused

My Green Light My green light is an ambiguous entity‚ consisting of multiple forms‚ each day varying from the next. This ever-changing pattern in my life is possibly a result of a void left behind from my childhood‚ as my parents had never encouraged or raised any desire to strive for a goal in me. As such I now have an inability to create a permanent goal for myself. My green light‚ in short‚ lacks conviction - it is deprived of the motivation required to maintain my interest‚ and eventually

BLUE BRAIN 1. Introduction The name of the world’s first virtual brain. That means a machine that can function as human brain. Computer simulations in neuroscience hold the promise of dramatically enhancing the scientific method by providing a means to test hypotheses using predictive models of complex biological processes where experiments are not feasible. Of course‚ simulations are only as good as the quality of the data and the accuracy of the mathematical abstraction of the biological

manipulations of fossil fuels represent an arduous and taxing means for producing energy to power further innovation. Therefore‚ novel methods of energy production are requisite to future technological progress. Therefore‚ investments into sources of renewable energy have expanded yet have met with heated discussion. The United States is a major consumer of resources such as coal‚ oil‚ and natural gas. Consumers of energy continue to grow exponentially‚ which poses a huge challenge to these diminishing

Polarized light are those that are vibrating in one direction- in a single plane such as up and down. Those that are vibrating in more than one direction -- in more than one plane such as both up/down and left/right -- are called unpolarized light. Generally‚ unpolarized light can be considered to be vibrating in a vertical and a horizontal plane. To polarize light‚ one can transmit the light through a polariod filter which will only allow light of single polarity to pass. The resulting light will be

Speed of Light Determining the speed of light is something that has been a very long and trying process. No one scientist could determine such a thing. Galileo was the first noted scientist to attempt experimentation on the speed of light. Other famous scientist‚ such as‚ Roemer‚ Foucault‚ Fizeau‚ Michelson‚ and Einstein added their own discoveries to the collage of information gathered through the years. Every scientist performed their experiments differently based on the knowledge and ability

Renewable Energy The use of renewable energy is probably one of the very few solutions for the energy needs of the future. It is considered as a form of safe‚ clean‚ and non terminating energy. In addition to all of that‚ renewable energy always brings marvelous economic benefits to any industry that uses it. Although renewable energy is expensive‚ time consuming‚ and less reliable sometimes‚ yet it still stands out as the solution for the energy needs of the future with respect to a safer environment
