General term for the processes by which human beings fashion tools and Machines

to increase their control and understanding of the material environment. The

Term is derived from the Greek words tekhne, which refers to an art or craft,

and logia, Meaning an area of study; thus, technology means, literally, the

study, or science, of Crafting. As technology evolves, scientist and historians

say that technology grows at A geometric rate without respect to geographical

limits or political systems. These Innovations tend to transform traditional

cultural systems, frequently with unexpected Social consequences. Thus

technology can be conceived as both a creative and a Destructive process.

Technology Has been evolving with us since the beginning of the Prehistoric age,

from the simplest off tools of the cave men to the now present future.

lligence.

Technology is Very important in our society, with out it we would not be able to

survive in our ever Changing society. Imagine is someone didn't invent

transportation. We would have not Discovered the other continents. Or not having

the technology to cope with our ever Growing population. We would have run out

of enough supply of food to feed ourselves. How about if cave men didn't

discover fire? We would have not survive even just for a Day. All these things

we owe to technology, so we must harness what it has to offer And further

improve our society. Inventions That Have Changed Our Lives: Telephone: In the

field of communication one of the most famous and useful invention In our modern

society is the telephone. Invented by Alexander Graham Bell, he has Made our

life so much easier and more productive. Saying that he has made an impact To

society would be an understatement. These telephone

transmit electronic pulses

That would then be converted to sound that is comprehendible to us humans, but

These telephones are big and bulky and they need wires to transmit these pulses.

Then Came the invention called A cellular telephone that designed to give the

user maximum Freedom of movement while using a telephone. A cellular telephone

uses radio signals To communicate between the set and an antenna. The served

area is divided into cells something like a honeycomb, and an antenna is placed

within each cell and connected by telephone lines to one exchange devoted to

cellular telephone calls. This exchange connects cellular telephones to one

another or transfers the call to a regular exchange if the call is between a

cellular telephone and a noncellular telephone. The special cellular exchange,

through computer control, selects the antenna closest to the telephone when

service is requested. As the telephone roams, the exchange automatically

determines when to change the serving cell based on the power of the radio

signal received simultaneously at adjacent sites. This change occurs without

interrupting conversation. Practical power considerations limit the distance

between the telephone and the nearest cellular antenna, and since cellular

phones use radio signals, it is very easy for unauthorized people to access

communications carried out over cellular phones. Currently, digital cellular

phones are gaining in popularity because the radio signals are harder to

intercept and decode. Also the fast growing popular video phones that work like

a normal telephone but includes the ability to transmit videos through the use

of a small camera. although these video phones are not yet popular in our

present society. they will soon be in every home in the world. Pagers: not all

inventions that where once practical remain practical. one example are the

invention of pagers. although these

pagers are still currently used in our

society they in my own opinion have out lived there use. these pagers where used

during the early 90s for the reason that they are more reliable, less expensive

and more portable than a cellphone. but now cellphones are cheaper and come in

sizes that are almost as small as a pager. so these pagers have out lived there

use and are now impractical to use in some countries. but in the Philippines we

have still retained it for they are "free" compared to a cellphone.

Satellite Band Radio (SBR) Satellite Band Radios are virtually unheard off in

our country. these radios are like normal radios but use satellites to transmit

there information instead of the normal analog radio waves used. the use of

these satellite radios give us better variety in the programs we listen to. and

will infact make the change of information faster and easier from country to

country. for a person will receive same information virtually at same time as

other radios abroad. Internet: internet is a term used for the interconnection

of computer networks that enables connected machines to communicate directly and

transmit data to any place in the world. in this part of the paper i will talk

about the communication possibilities of the internet. First is the E-mail the

E-mail is one of the first applications used in the internet. an E-mail is like

sending a regular mail to someone, but instead of waiting a long time for the

person to receive the mail, a person can get it in less than a second. and then

can reply to you just as fast. it works buy sending data to lots of

interconnected computers to a server that then sends it over to

the person the

mail is address to in less than a second. another program is the ICQ. The ICQ

basically works just like a pager. but with so much more, you can exchange

files, chat, play games and so on. also there is the IRC or Internet chat. these

programs are just like the two programs but it is done in real time and the

amount of people you can talk to at a time is almost endless. Television: The

television is one invention that is certainly very much used today. A Television

has a variety of applications in society, business, and science. The most common

use of television is as a source of information and entertainment for viewers in

their homes. Security personnel also use televisions to monitor buildings,

manufacturing plants, and numerous public facilities. Public utility employees

use television to monitor the condition of an underground sewer line, using a

camera attached to a robot arm or remote-control vehicle. Doctors can probe the

interior of a human body with a microscopic television camera without having to

conduct major surgery on the patient. Educators use television to reach students

throughout the world. there are basically two forms of television used today

they are the satellite and the cable television. the satellite t.v. transmits

channels through the use of satellites. while a cable t.v. uses cables to send

channels. although these are also sent through satellites to a cable operator

and then digested through cables to our t.v. soon television will be intertwined

with the net. you can surf and watch television at same time using a cable or a

satellite. the new televisions that are being sold to the market are now laced

with new features like PnP and automatic adjusting color t.v.s that change with

its

surroundings. Computers: People use computers in a wide variety of ways. In

business, computers track inventories with bar codes and scanners, check the

credit status of customers, and transfer funds electronically. In homes, tiny

computers embedded in the electronic circuitry of most appliances control the

indoor temperature, operate home security systems, tell the time, and turn

videocassette recorders on and off. Computers in automobiles regulate the flow

of fuel, thereby increasing gas mileage. Computers also entertain, creating

digitized sound on stereo systems or computer-animated features from a digitally

encoded laser disc. also the use of the internet with virtually infinite

possibilities through the use of interconnected computers. Computer programs, or

applications, exist to aid every level of education, from programs that teach

simple addition or sentence construction to advanced calculus. Educators use

computers to track grades and prepare notes; with computer-controlled projection

units, they can add graphics, sound, and animation to their lectures. Computers

are used extensively in scientific research to solve mathematical problems,

display complicated data, or model systems that are too costly or impractical to

build, such as testing the air flow around the next generation of space

shuttles. The military employs computers in sophisticated communications to

encode and unscramble messages, and to keep track of personnel and supplies.

Medical Drugs: The use of immunization to prevent disease predated the knowledge

of both infection and immunology. In China in approximately 600 BC, smallpox

material was inoculated through the nostrils. Inoculation of healthy people with

a tiny amount of material from smallpox sores was first attempted in England in

1718 and later in America. Those who survived the inoculation became immune to

smallpox. American statesman Thomas Jefferson traveled from his home in Virginia

to Philadelphia, Pennsylvania to undergo this risky procedure. A significant

breakthrough came in 1796 when British physician

Edward Jenner discovered that

he could immunize patients against smallpox by inoculating them with material

from cowpox sores. Cowpox is a far milder disease that, unlike smallpox, carries

little risk of death or disfigurement. Jenner inserted matter from cowpox sores

into cuts he made on the arm of a healthy eight- year-old boy. The boy caught

cowpox. However, when Jenner exposed the boy to smallpox eight weeks later, the

child did not contract the disease. The vaccination with cowpox had made him

immune to the smallpox virus. Today we know that the cowpox virus antigens are

so similar to those of the smallpox virus that they trigger the body's defenses

against both diseases. In 1885, Louis Pasteur created the first successful

vaccine against rabies for a young boy who had been bitten 14 times by a rabid

dog. Over the course of ten days, Pasteur injected progressively more virulent

rabies organisms into the boy, causing the boy to develop immunity in time to

avert death from this disease. Another major milestone in the use of vaccination

to prevent disease occurred with the efforts of two American

physician-researchers. In 1954 Jonas Salk introduced an injectable vaccine

containing an inactivated virus to counter the epidemic of poliomyelitis.

Subsequently, Albert Sabin made great strides in the fight against this

paralyzing disease by developing an oral vaccine containing a live weakened

virus. Since the introduction of the Sabin vaccine in 1961, polio has been

nearly eliminated in many parts of the world. As more vaccines are developed, a

new generation of combined vaccines are becoming available that will allow

physicians to administer a single shot for multiple diseases. Work is also under

way to develop additional orally administered vaccines and vaccines for sexually

transmitted diseases. Possible future vaccines may include, for example, one

that

would temporarily prevent pregnancy. Such a vaccine would still operate by

stimulating the immune system to recognize and attack antigens, but in this case

the antigens would be those of the hormones that are necessary for pregnancy.

The German chemist Felix Hoffman synthesized the acetyl derivative of salicylic

acid also called aspirin in 1893 in response to the urging of his father, who

took salicylic acid for rheumatism. Aspirin is currently the first-choice drug

for fever, mild to moderate pain, and inflammation due to arthritis or injury.

Of the few anesthetic agents known to the ancients, opium and hemp were the most

important. Both were taken by ingestion or by burning the drug and inhaling the

smoke. Nitrous oxide, discovered by the British chemist Sir Humphry Davy about

1800, was first used as an anesthetic in 1844 by the American dentist Horace

Wells. In 1842 the American surgeon Crawford Long successfully used ethyl ether

as a general anesthetic during surgery. He failed to publish his findings,

however, and credit for the discovery of the anesthetic properties of ether was

given to the American dentist William Morton, who in 1846 publicly demonstrated

its use during a tooth extraction. In 1847 the British physician Sir James

Simpson discovered the anesthetic properties of chloroform. Many other general

anesthetics have since been discovered. without these medicines it would be hard

for us to cope with the deseases that come our way. Radioactive Therapy and

Diagnosis: (Radiology) Radiology had its origin in the discovery of X rays by

the German physicist Wilhelm Conrad Roentgen in 1895. Roentgen was awarded the

first Nobel Prize in physics for his work. Medical images have subsequently been

produced by means of other forms of radiant energy. Thus, ultrahigh-frequency

sound waves may be so used and in the

technique called magnetic resonance

imaging, the images are obtained by recording the difference in relaxation time

of tissue nuclei in an electromagnetic field. For this reason the term medical

imaging has been proposed as more accurate than the traditional term diagnostic

radiology. Therapeutic radiology, also referred to as radiation oncology, has as

its principal basis the use of ionizing radiation. Increasingly common, however,

is the use in conjunction with radiation therapy of other forms of treatment,

such as hyperthermia. all these radioactive procedures are same they just vary

in the intensity of radiation they use. chemoteraphy for example is letting the

patient be bombarded with radiation to treat cancerus cells that have invaded a

persons body. the CT scaner and the MRI scaner are both machines use to diagnose

people to find out whats wrong with there body. for some deseases can't be

detected by just looking at a persons physical aspect. these desises are

internal and must be diagnosed and trated with radiation for them to be seen.

Weapons and Defense: Handguns, or pistols, as they are also known, were not

popular until after the development of the wheel lock, the first practical

mechanical ignition device, in the first half of the 16th century. Most early

handguns were too cumbersome to be carried in a holster by anyone on foot, and

the short barrels limited their accuracy and the distance they could propel

bullets. As a result, handguns were primarily used by cavalry troops in what

amounted to hit-and-run tactics. As ignition systems were improved, it became

possible to reduce the overall size and weight of handguns, until during the

18th century they became equally popular for use by foot soldiers. From the last

half of the 17th century to the first quarter of the 19th century,

most European

and United States military handguns had flintlock. and barrels 23 to 30 cm. in

length; smaller pocket handguns were also made for civilian use. No significant

improvements were made, however, until after 1836, when the American inventor

Samuel Colt patented a revolver design combining the metal percussion cap,

interchangeable mass-produced parts, and the revolving cylinder, which rotated

and locked automatically when the hammer was cocked. Improvements in ammunition

were introduced with the development of the self-primed metallic cartridge in

the mid-19th century. Minor improvements in revolver design continued until the

beginning of the 20th century, when emphasis in development was redirected to

the magazine-loaded semiautomatic handgun. Since then, the semiautomatic has

steadily gained in popularity and is now the primary military handgun of the

world. It is gradually replacing the revolver for police use. Modern

semiautomatic handguns carry two or three times more ammunition than revolvers

and are faster to reload. Their flat configuration generally makes them easier

to conceal. Even with the increased ammunition capacity, using newly developed

lightweight materials makes their loaded weight about the same as that of older

designs. Proponents of revolvers claim greater accuracy, reliability, and

safety, however, so it is unlikely that semiautomatics will totally replace

revolvers. In fact, muzzle-loading pistols and revolvers continue to be used for

sport and specialized worldwide competition. also bombs are used in todays world

to protect nations from invading ones. and thus came the invention In the early

1970s new types of conventional bombs, the so-called smart or guided bombs, were

developed for precision bombing in Vietnam. Maneuverable bombs guided by a laser

beam directed from the aircraft and reflected from the target can destroy such

targets as tanks or emplacements on contact. Other types can be designed to

guide themselves to targets radiating heat, such as

power plants, or can be

guided to the target from the delivery aircraft. In the latter case the bomb

transmits a picture of the target picked up by an on-board television camera.

Remote operating devices can then guide the bomb into direct contact with a

bridge, for example, or other objective. Laser-guided bombs can be used at

night; television-camera guided weapons are limited to daylight use, however.

and The A-bomb was developed, constructed, and tested by the Manhattan Project,

a massive United States enterprise that was established in August 1942, during

World War II. Many prominent American scientists including the physicists Enrico

Fermi and J. Robert Oppenheimer, and the chemist Harold Urey, were associated

with the project, which was headed by a U.S. Army engineer, Major General Leslie

Groves. these forms of weaponry may be destructive in most cases but they do

play a vital role in protecting ones self in the society we live in. The

advantages and disadvantages of technology: Technology plays a vital role in our

society. without it we can't evolve and cope up with the ever changing world we

live in. some of its advantages are the increase in efficiency and productivity

of how we do and manage things. we can do things twice as fast and twice more

efficient than we did a century ago. and this makes up for the growing

population of the world, so that everyone may have enough to support themselves

and satisfy there needs. Technology gives us larger possibilities by giving us

ideas that we havent thought about in the past. we can do more things now

that technology has helped us evolve. it further enhances our perspective in the

things we do. and makes simpler solutions in the problems we face everyday. it

also gives us

easier accessibility and mobility. it makes production move

faster. communication more efficient and cost worthy. we can now get information

almost anywhere and with these information we get, we use them in our daily

lives. but not everything that technology has to offer is good. for every

advantages technology gives us it also comes with a subsequent disadvantages.

some of them are the complexities of society. not everyone can cope with the

advancements of technology. these people can get left behind. everything becomes

more complicated and what is expected of us also grows. life was more simple in

the old days. but due to technology everything has become more complex. another

is the increase of indolence in our society. since everything has become more

accessible and more convenient people tend to log off and become lazy. this is a

very big problem to us. it decreases our morality and soon we will be so

engulfed in it we cant get out from its grip. with better solutions and easier

work load comes the over dependence of people to technology. the tend not to

think for them selves anymore and let technology take over there lives. this is

bad for its makes us the slaves of technology instead of us controlling them

they are the ones that control us. technology is important in every society. but

if we insist on using and depending on it a lot it can also destroy us. so we

must think for ourselves if it is worth it and use it as we see fit.
