How Guns Work

... the muzzle, or open end. Nowadays firearms are a little more sophisticated. However, the physics behind all guns remain the same. Weapons such as cannons, shotguns and rifles, work on the basic idea of conservation of momentum and the change in energy from potential to kinetic. When the trigger is pulled the hammer hits the firing pin. The firing pin then hits the primer which causes the powder to burn hence producing lots of gases. This causes the volume behind the bullet to fill with extremely high pressure gas. The gas pushes on ev ...

Air Bags

... auto industry has tried to develop new safety features in cars. Airbags is one of their safety features. This so called safety feature has caused deaths and life long injuries to everyone from kids to adults. Airbags are an automatic crash protection system that deploys quicker than the blink of an eye. Crash sensors, located on the front of the vehicle or in the passenger compartment, measure deceleration, the rate at which a vehicle slows down. When these sensors detect decelerations indicative of a crash severity that exposes the o ...

Artificial Intelligence

... tasks more complex than straightforward programming, although still far from the realm of actual thought. The most important fields of research in this area are information processing, pattern recognition, game-playing computers, and applied fields such as medical diagnosis. Current research in information processing deals with programs that enable a computer to understand written or spoken information and to produce summaries, answer specific questions, or redistribute information to users interested in specific areas of this information. Ess ...

Technology And The Future Of Work

... a near workerless society of abundance and leisure. (J Rifkin 1995 p.42) This paper will consider developments in technology, robotics, electronic miniaturisation, digitisation and information technology with its social implications for human values and the future of work. It will argue that we have entered post modernity or post Fordism, a new age technological revolution, which profoundly effects social structure and values. Some issues that will be addressed are: elimination of work in the traditional sense, longevity, early retiremen ...

Internet Access: Flat Fee Vs. Pay-Per-Use

... to make serendipitous discoveries. "Pay- per-use" situations give the public the incentive to focus their attention on what they know they already want, or to look for well-known items previously recommended by others. In "pay-per-use" environments, people tend to follow more traditional paths of discovery, and seldom explore totally unexpected avenues. "Pay-per-use" environments discourage browsing. Imagine how a person's reading habits would change if they had to pay for each article they looked at in a magazine or newspaper. Yet many o ...

Development Of Computers And Technology

... 200's, and the powerful Silicon Graphics Workstations, the core of the machine has stayed basically the same. The only thing that has really changed in the processor is the speed that it translates commands from 1's and 0's to data that actually means something to a normal computer user. Just in the last few years, computers have undergone major changes. PC users came from using MS-DOS and Windows 3.1, to Windows 95, a whole new operating system. Computer speeds have taken a huge increase as well, in 1995 when a normal computer was a 4 ...

The Office Of Tomorrow

... contents of his briefcase are spread on the table. As he sifts through a stack of paperwork and types responses into the computer, he periodically picks up a cordless phone and places a call to a colleague or associate. As he talks, he sometimes wanders across the room. To be sure, this isn't your ordinary corporate environment. Smith doesn't have a permanent desk or workspace, nor his own telephone. When he enters the ad agency's building, he checks out a portable Macintosh computer and a cordless phone and heads off to whatever nook or c ...

How Cell Phones Work

... phone is to compare it to a CB radio or a walkie-talkie. A CB radio is a simplex device. That is, two people communicating on a CB radio use the same frequency, so only one person can talk at a time. A cell phone is a duplex device, so it uses one frequency for talking, and a second separate frequency for listening (Dang). A CB radio has 40 channels. A cell phone can communicate on 1,664 channels. Cell phones also operate within cells and they can switch cells as they move around. Cells give cell phones incredible range. A walkie-talkie can ...

Natural Language Processing

... computer language commands, but instead be able to process and understand the English language. This is the concept behind Natural Language Processing. The phases a message would go through during NLP would consist of message, syntax, semantics, pragmatics, and intended meaning. (M. A. Fischer, 1987) Syntax is the grammatical structure. Semantics is the literal meaning. Pragmatics is world knowledge, knowledge of the context, and a model of the sender. When syntax, semantics, and pragmatics are applied, accurate Natural Language Processing ...

Censorship Of The Internet And The Tyranny Of Our Government

... and ideas to hundreds of people at a practically non-existent cost. Numerous factors indicate censorship of this force is not possible, and not the government's place. It should be left up to the users to decide what is broadcast. Most importantly, censorship of the Internet impairs the expression of ideas and infringes against the First Amendment of the Constitution. First of all, censoring the Internet as a whole is not possible, so why even try? Cyberspace is the most decentralized form of communication today making policing ...

Digital Cameras

... to $1,000. So the question is: why buy a camera for that amount of money, when you could by a decent 35mm camera? There are essentially three reasons. First, if you want to bring images into your computer for desktop publishing, web design, or other computer applications, there’s no easier way than capturing the images directly to a digital format. Second, do away with film and processing costs, which would make up the price difference over the life of the camera. Last, since it doesn’t cost anything to take a photograph picture ...

The Internet: How It Works And How It Effects The World

... of the computers was under enemy attack, the information could be automatically transferred to other links. Fortunately, the Net is not usually under enemy attack. The ARPANET was very successful, and every university in the country wanted to sign up. Because so many people wanted to use the Net, ARPANET started getting hard to manage, especially with many university sites on it. Therefore, it was broken into two parts: MILNET, which had all the military sites, and ARPANET, which had all the nonmilitary sites. "The two networks remained c ...
