...Science and technology are probably the most debated topics in society. Scientific and technological developments have been debated as to whether they affect people's life styles and cause hassle. On the contrary, science and technology has improved our way of life for the better of mankind. Medical advancements, computers and simple inventions such as the light bulb are all examples of how science and technology is beneficial. In each of these cases, there are no undesirable changes to people's life styles. If it were not for many, if not all, of these changes in our history, we as an economy and nation would have fallen apart. Looking into the past, we can see all of the beneficial advancements we have made and how far we have come. Scientific and technological developments such as medical research to find a cure for AIDS, modern health care and computers are beneficial in the role of improving people's lives and do not come at the cost of undesirable changes to them. Today with new technology, medical research is being done everyday to help find cures or vaccines for devastating diseases such as Cancer, AIDS, Alzheimer's and Leukemia. Being diagnosed with one of these diseases is hard, but growing up with them is even harder. "AIDS was first identified in the USA in 1981. The epidemic has now spread to every part of the USA and to all sectors of society" (Noble). Growing up, I had two siblings who were diagnosed with AIDS. My older sister Katie was unfortunately...

...What do you find most striking/interesting/relevant/significant/innovative about the film and why? Given the lack of advanced of digital technology available to the film industry then, the way special effects were created was through a synthesis of camera work and the use of props. The low budget of the film had compelled them to use props consisting of condoms, oatmeal etc. together with filming techniques to replicate certain scenes like the tunnels or the heat-ray effect. These innovative methods of mixing prop-use and camera tricks, have mostly been replaced by digital technology. Poor representations of what we would come to expect of advanced technology, these special effects back then would have been the acceptable visual standard of portraying the scientific fantasies of the 1950s era. These different special-effects standards notwithstanding, the genre-function of science-fiction is to represent a sort of fantasy with hyper-real elements, while concurrently being a parody of contemporary issues. Hence, with the normative expectations of that genre in mind, it is interesting to see how cinematic expectations have changed, for example, to see how boiled-oatmeal coupled with camera tricks could pass off as a heat-ray’s effect then. However, a judgment regarding the proximity to reality between past and present visual effects can be passed while avoiding anachronisms. Hence, where hyper-real elements – successful exaggerations of reality where representation fades into...

...Human cloning occurs naturally with phenomena like twins and triplets, but the same outcome of a genetically identical individual created in a lab is not as well received. Over the years, cloning has transformed from a thing of fantasy to one of reality. Current research is bringing us closer than ever to cloning humans, but what will happen if we succeed? The word clone is defined as being an exact genetic replica of a molecule, cell, plant, animal or human being. The term cloning refers to the technological process of creating a clone. The use of cloning technologies has been in place for the past 50 years, though it wasn’t until 1996 that the first mammal was cloned from a somatic cell. Dolly, the world’s first cloned lamb, brought cloning and its ethical implications into the spotlight after she was successfully cloned from an udder cell of a six-year-old sheep. Dolly was put to sleep in 2003 after suffering from lung disease, as well as premature arthritis. Having lived only six and a half years instead of the expected 11 – 12, Dolly’s passing also brought to light questions regarding the health and life expectancy of cloned animals. Though her life was short, she left a long lasting imprint in the field of modern biological research. The successful cloning of Dolly led to many other advances in the biological community, however, as of 2014 no human has ever been successfully cloned. Human cloning is a hotly debated topic in the science and religious communities...

...would vary. A wireless network can potentially be more expensive. The reason for this is because the security of data should be a main priority. Data that is sent through wireless transmissions by default is unsecure and anyone with a wireless device could connect and use the bandwidth of that access point. This is why securing a wireless access point is very important. Most wireless access points are ready with specific encryption methods. Wired Equivalent Privacy (WEP): This encryption allows 64 or 128 bit encryption and uses a word and converts it to hexadecimal. This encryption is possible to be hacked with the correct hacking tools. It is always best to use the highest encryption. There is also 2 versions Wi-Fi Protected Access WPA1 and WPA2. Some wireless routers do not include this protection, and this is one reason why this technology would be more expensive. WPA1 and WPA2 is very difficult to break, but it is still possible. The WPA security uses 256 bit encryption and uses a passphrase that is...

...Wireless Technologies Introduction As wireless technology has begun to mature, the demand for wireless products has increased as new applications for the technology are realized. One application for wireless technology at the U.S. Naval Academy is to use the wireless capability to enhance classroom instruction. Currently the Electrical Engineering and Physics Departments have wireless access points and wireless laptops/desktops available for classroom instruction. The purpose of this report is to provide the technical research necessary to aid decision makers in determining which wireless technologies the Naval Academy should invest. Background In a wireless network, computers communicate with the network through a radio path vice a cable. The device that contains the radio and connects to the wired network is called the “Access Point”. Each client that communicates with the access point must have a wireless PCMCIA card. Once both devices communicate via radio transmission, network access can begin. Each client is configured to communicate with a single access point. A client can move from one access point to another. Roaming from access point to access point (cell to cell), similar to cellular telephone technology, is possible. Technology Discussion There are three wireless technology standards on the market today: Bluetooth, 802.11b, and 802.11a. A new standard, 802.11g, was recently approved by IEEE and products using this technology are expected...

...Topic: Write a paragraph about “Qualities of a good neighbor” There are many attributes to a good neighbor, but i will highly appreciate the one who is helpful , sympathetic and honest. First of all, a person with the quality of helpfulness will be put on top of my list of desirable neighbors. It is a fact that all of us have our own difficulties and nothing is more meaningful than a hand given to us in time of need. For instance, when you are busy organizing a get-together with all members in your family but the fact that you have forgotten to purchase one of the most important ingredients threatens to ruin your main dish. However, you can easily have the neighbors to travel to the market and buy it for you. That’s an accurate picture of a helpful neighbor who you should be grateful to. Furthermore, a kind neighbor from my point of view would have the quality of sympathy. Having someone to care about you and share their feelings with you is necessary when you are experiencing a tough time in life . For example, a nice neighbor to a widow who has just lost her husband in a terrible accident must help her to overcome with grief. There may be cases where there are children whose their parents got dirvoced. In such cases, a good neighbor is required to treat them equally to other kids instead of gossiping anything about them. In addition to helpfulness and sympathy, a neighbor who possess a sense of integrity would be perfect. I can endure the fact that there are some two-faced...

...to: navigation, search For the radio station, see WIFI (AM). Wi-Fi logoWi-Fi ( /ˈwaɪfaɪ/, also spelled Wifi or WiFi) is a popular technology that allows an electronic device to exchange data wirelessly (using radio waves) over a computer network, including high-speed Internet connections. The Wi-Fi Alliance defines Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards".[1] However, since most modern WLANs are based on these standards, the term "Wi-Fi" is used in general English as a synonym for "WLAN". A device that can use Wi-Fi (such as a personal computer, video game console, smartphone, tablet, or digital audio player) can connect to a network resource such as the Internet via a wireless network access point. Such an access point (or hotspot) has a range of about 20 meters (65 feet) indoors and a greater range outdoors. Hotspot coverage can comprise an area as small as a single room with walls that block radio waves or as large as many square miles — this is achieved by using multiple overlapping access points. "Wi-Fi" is a trademark of the Wi-Fi Alliance and the brand name for products using the IEEE 802.11 family of standards. Only Wi-Fi products that complete Wi-Fi Alliance interoperability certification testing successfully may use the "Wi-Fi CERTIFIED" designation and trademark.
