The Fresnel Lens Do you know what the largest light house in America? Or how many steps it takes to get to the top? I do. It’s Cape Hatteras light house in Buxton‚ NC. It was completed in 1971 and stands 193 feet in the air. It takes 268 steps to climb to the top. I visited this light house in August of 2010 I had the pleasure of seeing the 6‚000 lb. bronze and crystal lens. In 1803 it was replaced due to being damaged by vandals. Light houses from the 18th century used burning candles‚ oil lamps

created the universe in six 24-hour days. Muslims use science to back up their beliefs. The Qur’an mentions a period of six days‚ but these are not necessarily 24-hour days. With Einstein’s theory of relativity‚ it is discussed how travelling at near the speed of light and how gravity can slow down time. Using this theory‚ Muslims break the six days into six periods of time. This allows Muslims to come to the same conclusion that the universe is roughly 16 billion years old. Muslims use science to reaffirm

frame lenses have a bigger image circle than the image circle on crop lenses. This is the key difference between these two lens types and we have seen this in the many examples of cropped vs full frame. As I said earlier‚ full frame lenses have no problem adjusting to cropped sensors because the image circle is big anyway. On the other hand‚ if you were to put a cropped lens on a full frame sensor the image circle would be too small to cover the entire sensor and‚ as a result‚ you would get blackened

An Open Mind to an Open System AN OPEN MIND TO AN OPEN SYSTEM The Open System Theory was initially developed by Ludwig von Bertanlanffy (1956)‚ a biologist‚ but it was immediately applicable across all disciplines. It defines the concept of a system‚ where "all systems are characterized by an assemblage or combination of parts whose relations make them interdependent". As one moves from mechanical to organic and social systems‚ the interactions between parts in the system become more complex and

Brofenbrenner’s Ecological System Theory 1/30/2013 Brofenbrenner’s Ecological System Theory The Brofenbrenner’s Ecological System Theory has been renamed recently as the ‘Bioecological System’s Theory’. This theory throws light on the development of a child‚ with the virtue of the system of relationship context‚ which forms their environment (Thudge et al) . This theory further suggests that different complex environmental layers mold them up. This theory has made great efforts to explain

Systems theory appears to be useful when addressing several implementation processes and strategies (Lindskog‚ 2012). When attempting to address immediate issues this form of the systems theory may be an effective rapid response assessment tool‚ notably for issues associated with minimal potions of a population; such as the micro (individual) or mezzo (family) levels. Implementing it as an assessment tool may allow a program developer or public health professional to accurately identify the source

Systems & Communication Theory System: A system is defined as a bounded set of interrelated elements exhibiting coherent behavior as a trait (Constantine‚ 1986). Families are considered systems because they are made up of interrelated elements or objectives‚ they exhibit coherent behaviors‚ they have regular interactions‚ and they are interdependent on one another. Boundary: Boundaries are the interface between systems and subsystems. In family theories‚ boundaries are set by functions of the

Information theory is a branch of applied mathematics and electrical engineering involving the quantification of information. Information theory was developed by Claude E. Shannon to find fundamental limits on signal processing operations such as compressing data and on reliably storing and communicating data. Since its inception it has broadened to find applications in many other areas‚ including statistical inference‚ natural language processing‚ cryptography generally‚ networks other than communication

Len the Unknown Legend Sebastian Garcia Period 6 11/21/2013 The chances of a person to go to the NBA and play professional basketball are three in ten thousand‚ .03 percent of people are able to make it to the NBA.
