Communication Devices Recently, while enjoying a sunny afternoon with some friends, a few baby boomers I know were relating some experiences that seem quite pertinent to the subject of how communication is or will change. Young Aaron, the son of a guest, was at a loss when told to call home. It seems our young guest had never had to use a rotary telephone. Confronted with this icon of past technology, Aaron went away with a new experience to relate. Another guest, upon hearing of Aaron\'s plight
Electromagnetic Spectrum The electromagnetic spectrum is made up of six different types of waves. Radio waves, Microwaves, Infrared waves, Visible light, Ultraviolet light, X-rays and Gamma rays. The radio waves are used to transmit radio and television signals. The infrared waves are used to tell temperature of areas. Visible light is all the colors that we can see. Ultraviolet light can help things grow but to much can cause diseases such as skin cancer. X-rays are used as a tool to find broke
Enviormentalism Evironmentalism: The Next Step Broad Social Change Through Personal Commitment Introduction In the last thirty years, America has witnessed an environmental revolution. New laws like the 1963 Clean Air Act and the 1974 Safe Drinking Water Act forged new ground in political environmentalism. Social phenomena like Earth Day, organized by Dennis Hayes in 1970, and the beginning of large-scale recycling, marked by Oregon\'s 1972 Bottle Bill, have help change the way Americans think a
Environmental Air Pollution My views of the environment are rooted in my belief in creation. I do not believe that life on earth began spontaneously, nor do I believe that the earth is so delicately balanced. I don’t believe that the earth and its ecosystem are fragile. Many radical environmentalists do, they believe man can come along, all by themselves and change everything for worse. After hundreds of millions of years, they believe that we are the last two generations of human existence. And
Comparison Of Mail Communications New technologies have always allowed us to do things faster, more efficiently, and more professionally than ever before. Generally, every new technology is a step forward for speed and productivity. But, despite this paradigm, the coming of the latest mail communications innovation has brought many pros and cons with the package. Electronic mail could be the greatest thing since sliced bread, but there are many who find flaws in it. We are now going to take a mo
Eye tracking techniques improve aircraft simulators A simulated flight environment for pilot training may soon be made more realistic through the use of eye-tracking technology developed by researchers at the University of Toronto\'s Institute of Biomedical Engineering (IMBE). Many safety and cost benefits are obtained by training aircraft pilots under simulated conditions, but to be effective the simulation must be convicingly realistic. At present, th e training facilities use large domes and
Computers Only once in a lifetime will a new invention come about to touch every aspect of our lives. Such a device that changes the way we work, live, and play is a special one, indeed. A machine that has done all this and more now exists in nearly every business in the US and one out of every two households. This incredible invention is the computer. The electronic computer has been around for over a half-century, but its ancestors have been around for 2000 years. However, only in the last 40
Facisc FASCISM When the word “fascism” is mentioned people usually associate the word with German Nazis’. There is more to fascism than just German Nazis.’ Fascism is an interesting topic that should be further examined and explained so it is no longer simply associated with German Nazis’. This essay will explain what fascism is (definition), how fascism groups are run, the ideology of fascism, and some past examples of how fascist governments operated. Fascism is a form of counter-revolutionary
Fruit Flys Introduction From simple heredity experiments with garden peas, to cloning sheep, the field of genetics has come a long way. Now we are closer to mapping out the human genetic map due to advances in technology, and years and years of research. Perhaps the most influential and groundbreaking scientist, Gregor Mendel, he was responsible to provide a path to where genetics is now today with his experiments of garden peas. In lab, fruit flies were crossed to observe inheritance patterns i
GENE THERAPY Many diseases seen today are the result of a defective gene in the DNA of the patient and can not be cured using the traditional methods such as antibiotics and antiviral medication. The victims are now looking to gene therapy as a potential cure for their problems. Bob Williamson introduces us the concept, procedures, and problems associated with gene therapy in his article, Gene Therapy . Along with the appearance of the recombinant DNA technology, it becomes possible for human be
Genetic Engineering, History And FutureAltering The Face Of Science Science is a creature that continues to evolve at a much higher rate than the beings that gave it birth. The transformation time from tree-shrew, to ape, to human far exceeds the time from analytical engine, to calculator, to computer. But science, in the past, has always remained distant. It has allowed for advances in production, transportation, and even entertainment, but never in history will science be able to so deeply aff
Computers And Finance Computers have made financial bookkeeping much easier, and people no longer have to spend hours tracking investments or pay someone else to do their taxes. Moreover, the advancement in technology has allowed governments to cut back on the number of big companies and employees hired to process tax returns, resulting in the saving of millions of dollars. Although these advancements are extraordinary, they are not without their shortcomings. The IRS has had increased trouble i
Computers, Hackers, And Phreaks The Internet is a wondrous place. Practically anything you could ever want is available on the Net. It\'s like a big city, it has the highly prestigious areas, and the sex-ridden slums (Mitchell). It has the upstanding citizens, and it has the criminals. On the Net, crime is more abundant than in a large city, though, mainly because of the difficulties in tracking and prosecuting offenders. Even from its beginnings, the Internet has always been a battlefield betwe
Home Tech The Toilet Yes...those tales you\'ve heard are true. The toilet was first patented in England in 1775, invented by one Thomas Crapper, but the extraordinary automatic device called the flush toilet has been around for a long time. Leonardo Da Vinci in the 1400\'s designed one that worked, at least on paper, and Queen Elizabeth I reputably had one in her palace in Richmond in 1556, complete with flushing and overflow pipes, a bowl valve and a drain trap. In all versions, ancient and mod
Human Cloning Imagine it is the year 2008. As you pick up your daily issue of the New York Times, you begin to read some of the interesting articles on the front page. The top story of the paper reads, Germany Wins All Gold Medals at the Olympic Games: Is Cloning in Competitive Events Fair? Other interesting articles reported on the front page include: Rock Star Stacy Levesque and Lover’s Nuclear Transplanted Child is Born and Former President George Bush’s Cloned Heart Transplant A Success. The
Computers Mimic The Human Mind The mind-body problem has captivated the minds of philosophers for centuries. The problem is how the body and mind can interact with each other if they are separate and distinct. One solution to the problem is to replace any mental term with a more accurate physical description. Eliminative Materialists take this idea to the extreme by stating that everything that is believed to be mental will someday be explained in terms of the physical world. One way that people
Human Genome GENOME PROJECT Adam and Eve were doomed for trying to be like god, this is the same damnation mankind is headed to. Everyone’s dream is to have absolute power and control of everything. The genome project and DNA engineering gives man the ability to create life and cu omize life to his specific needs of likes. So how good is too good? Man’s ability to make life or create perfect human beings so they can be in a state of Utopia will disturb the balance of nature. Every individual, ev
Ice Caps Melting The Ice Caps Melting Are global warming and the greenhouse effect causing the ice to melt and the sea levels to rise? Antarctica and Greenland hold a good population of the world’s ice in the ocean. The article, “Answers to sea level rise locked in ice” by Jack Williams of USA Today, describes what is happening with the polar ice caps, and how it is going to effect the world. Williams compares the amount of ice in Antarctica to the size of “USA’s 48 contiguous states and half of
Computer Crime Laws must be passed to address the increase in the number and types of computer crimes. Over the last twenty years, a technological revolution has occurred as computers are now an essential element of today\'s society. Large computers are used to track reservations for the airline industry, process billions of dollars for banks, manufacture products for industry, and conduct major transactions for businesses because more and more people now have computers at home and at the office
Intelligent Design of the The search for knowledge about the origin of humanity is as old as its inhabitants. Since the early 1800\'s mankind has narrowed the debate to creation by a Supreme Being and the theory of evolution. Ever since then, science has been at odds against religion. Now it appears that science is returning to religion. Scientists are finding proof that the universe was created by a Supreme Being. The word evolution refers to the change of something over a period of time(Webste
Issues Of Human Cloning The Issue of Human Cloning The recent news of the successful cloning of an adult sheep-in which the sheep\'s DNA was inserted into an unfertilized sheep egg to produce a lamb with identical DNA-has generated an outpouring of ethical concerns. These concerns are not about Dolly, the now famous sheep, nor even about the considerable impact cloning may have on the animal breeding industry, but rather about the possibility of cloning humans. For the most part, however, the et
Computer Hackers Computer Hacker The meaning of Hacker is one who accesses a computer which is supposably not able to be accessed to non authorised people of the community. Hackers may use any type of system to access this information depending on what they intend on doing in the system. Methods Hackers may use a variety of ways to hack into a system. First if the hacker is experienced and smart the hacker will use telnet to access a shell on another machine so that the risk of getting caught is
Land Ethics Land Ethics in Our Communities While wading through the reserved reading in the library, I came across the article, “The Land Ethic”, which caught my eye, as well as sparked an interest deep within me. It revealed the idea that we, as humans, tend to be quite caught up in the idea of community; community between neighbors, co-workers, etc. seems to be something we strive for in our society. It seems that we have not integrated the land into our idea of community, and I feel that this
Lasers When most people see a laser beam they are amazed by its unique physical properties. Laser light is so unique from other light because it is coherent; unlike ordinary light, which travels in all directions, laser light travels in a straight beam. The word laser is an acronym for Light Amplification by Stimulated Emission of Radiation. The history of the laser is very interesting. Lasers have changed immensely since they were first invented. Before the laser was invented, Charles Townes de

Living In Space Living In Space: Energy Space is filled with radiant energy and beyond earth\'s atmosphere this energy flow more steadily and more intensely from the sun than that which penetrates to the surface of the Earth. So an abundant and essential source of energy that would be used in space for the space colony would be solar radiation by developing satellite solar power stations. To live in space, humans must be protected from the fierce intensity and penetrating wavelengths of unattenu
The Communication Decency Act: The Fight For Freedom of Speech on the Internet The Communication Decency Act is a bill which has insulted our right as American citizens. It a bill which SHOULD not pass. I\'ll share with you how Internet users are reacting to this bill, and why they say it is unconstitutional. Some individuals disagree with one part of the bill. According to query/z?c104:s.652.enr:, which has the Communications Decency Act on-line for public viewing
Computer Viruses A computer virus is a relatively small program that attaches itself to data and program files before it delivers its malicious act. There are many distinct types of viruses and each one has a unique characteristic. Viruses are broken up into to main classes, file infectors and system or boot-record infectors. A file infector attaches to ordinary programs usually affecting .COM and .EXE files. These two files are subject to infection though some can infect any program from which
Metallic Hydrogen Hydrogen: the most abundant element in the universe. Normally it has been considered to remain a non-metal at any range of temperatures and pressures. That is, until now. Recently this year, hydrogen was changed into a metallic substance, which could conduct electricity. An experiment conducted by William J. Nellis et al. at the Lawrence Livermore National Laboratory accomplished this feat. Hydrogen was converted from a non-metallic liquid, into a liquid metal. The likelihood t

Military aircraft has become more sophisticated in variety, effectiveness in war situations, and special maneuvering techniques in recent years. With the advance of stealth technology, many new and very effective aircraft have been developed. The F-117A was used during Operation Dessert Storm and every plane came back without a
Conditional And Iterative Data Types Conditional and Iterative A programming language cannot be a programming language with out its conditional and iterative structures. Programming languages are built to accomplish the task of controlling computer input and output. A programmer must use every tool available to complete his/her given tasks, and conditional as well as iterative statements are the most basic items of programming which must be mastered. Many different programming languages can demo
Myasthenia Gravis In 1890, German medical professor Wilhelm Erb and other physicians had been observing several cases of a neuromuscular disease that they believed was affecting how nerve impulses were transmitted to muscle at the neuromuscular junction. The patient’s experienced a grave muscular weakness and Wilhelm named it myasthenia gravis. Through further research, the physicians discovered whether it affected the eye muscles first, or created difficulty in talking, chewing and swallowing,
Nationalism In The Global Village INTRODUCTION With the dawning of the information age there has been a shrinking of relative distances between people and places all over the world. With an increase in international communication comes an increase in cultural sharing. Cultures all over the planet reflect influences of neighboring cultures and other international trading partners. As these and many other factors work towards creating a global village many people are baffled by the increase in nat
Cray SuperComputer The Cray X-MP/22 manufactured by Cray Research Incorporated (CRI) of Minneapolis, Minnesota was delivered and installed at the U of Toronto this September. The Cray is a well respected computer - mainly for its extremely fast rate of mathematical floating-point calculation. As the university states in its July/August computer magazine ComputerNews , the Cray\'s level of performance should enable researchers with large computational requirements at the university of Toronto and
Nuclear Energy Nuclear energy by definition is the energy consumed or produced in modifying the composition of the atomic nucleus. Nuclear energy is used for things such as atomic bombs, hydrogen bombs and other nuclear weapons. Nuclear energy can also be used for powering electricity-generating plants all over the world. There are many arguments for and against nuclear power. Nuclear power is an inexpensive clean source of power. Others feel that because of the hazardous radiation emitted durin
Nuclear Power Radioactive wastes, must for the protection of mankind be stored or disposed in such a manner that isolation from the biosphere is assured until they have decayed to innocuous levels. If this is not done, the world could face severe physical problems to living species living on this planet. Some atoms can disintegrate spontaneously. As they do, they emit ionizing radiation. Atoms having this property are called radioactive. By far the greatest number of uses for radioactivity in Ca
Nuclear Technology What is the first thing that comes to your mind when you hear Nuclear Disarmment? For me, the first thing that comes to my mind is the incident on August 1945 at Hiroshima and Nagasaki, which according to official sources killed around 1.5 million innocent Japanese people. First of all, In August 1945, U.S dropped two atom bombs in Hiroshima and Nagasaki, which ended the World War II and started the nuclear race in the world. It was the first time in the world when a nuclear w
Nutrition “You are what you eat”, goes a famous saying. If that’s truly the case, then a lot of Americans would appear to be unhealthy, chemically treated, commercially raised slabs of animal flesh. While that is not a particularly pleasant thought, it is nonetheless a description of the typical American omnivore who survives on the consumption of big macs and greasy french fries. It’s true, and what have the average Americans done about this problem? Asked for seconds and tell themselves that t
Crypography Cryptography is way you can keep information secure. A person who does not know the method used to change the information to keep it secure cannot copy the method used or reverse the change. The basic components of cryptographic systems are used to encipher (scramble) information so that it is difficult to determine the meaning without the appropriate key or key(s) to decipher (unscramble) the information. The components include cryptographic algorithms (mathematical functions) for e
Phytoremediation Introduction: In recent years it has become clear that some environmental chemicals can cause risks to the developing embryo and fetus. Evaluating the developmental toxicity of environmental chemicals is now a prominent public health concern. The suspected association between TCE and congenital cardiac malformations warrants special attention because TCE is a common drinking water contaminant that is detected in water supplies throughout the U.S. and the world. There is a lot of
Data Compression ‘Data Compression’ just sounds complicated. Don’t be afraid, compression is our good friend for many reasons. It saves hard drive space. It makes data files to handle. It also cuts those immense file download times from the Internet. Wouldn’t it be nice if we could compress all files down to just a few bytes? There is a limit to how much you can compress a file. How random the file is, is the determining factor to how far it can be compressed. If the file is completely random an
Polymers Polymers are large molecules composed of smaller molecules called monomers. Monomers are produced and either grow together or are assembled to produce a single polymer. There are synthetic and natural polymers. Some examples of natural polymers would be wood, starches, fingernails, and hair. Synthetic polymers are usually referred to as plastics. Petroleum, is the primary monomer used to produce polymers. An English chemist named Alexander Parkes was the first scientist to produce the f
Predictions for genetic engeneering I think that there are going to be a lot of new changes in the upcoming millennium. I think the change that will have the biggest impact will be genetic engineering. One side of genetic engineering will be that parents will be allowed to chose the outcome of their baby. Another side is cloning. I think the biggest part will be correcting DNA to get rid of diseases. That could also be a part of choosing your baby because you could fix any problems before it is
Data Mining In A Nut Shell In today’s business world, information about the customer is a necessity for a businesses trying to maximize its profits. A new, and important, tool in gaining this knowledge is Data Mining. Data Mining is a set of automated procedures used to find previously unknown patterns and relationships in data. These patterns and relationships, once extracted, can be used to make valid predictions about the behavior of the customer. Data Mining is generally used for four main t
Problems And Prevention\'s Of Ebola And AIDS Viruses have become of great concern all across the world in the last few decades. The most common and the most talked about killer virus is AIDS, a virus that starts out as HIV and then proceeds to develop into a immune breaker that ultimately kills its human host. So far, there is no cure for AIDS, and most unfortunately the numbers of deaths from AIDS only continues to grow. However, another virus has gained much public and national attention. That
Radio Waves Before beginning our research on radio waves, to us, radio waves were just waves going through the atmosphere, carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves, and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves, which represent voice an
Rainforest Dilema Can you picture our earth without forests? Many of us can’t. Forests cover approximately one fifth of the worlds land surface and play an important role in our everyday lives (Dudley 4). Forests provide us with many products and services from helping maintain erosion to providing jobs for our citizens. Humanity depends on the survival of a healthy ecosystem and deforestation is causing many social, economic and ecological problems. One ecological problem is Global warming witch
Reforestation The purpose of this written report is to inform the reader about the concerns and facts involved with reforestation. Reforestation began in Ontario after World War II. What happened was, professional foresters were assigned to an area and became responsible for its well being. Under the Crown Timber Act, long term management was prepared. Then the many steps needed to rebuild a forest began. Included in this report will be information on the effects of cutting and replanting, such
Data Parity December 1996 Parity/Non-parity Parity check Early transmission codes had a serious problem in that a bit could be lost or gained in transmission because of an electrical or mechanical failure/ If the loss went undetected, the character received on the other end of the lime was incorrect. To Prevent this from happening, a parity check system was developed. Each character is represented by a byte consisting of a combination of intelligence bits (seven bits in ASCII and eight bits in E
