Science & Technology- necessity & application





Science and Technology has been around from the beginning of time. It evolved from the

everyday efforts of people trying to improve their way of life. Throughout history,

humankind has developed and utilized tools, machines, and techniques without

understanding how or why they worked or comprehending their physical or chemical

composition. Before we go any further a definition has to be given for both Science and

Technology because they are both different in their own right even though the two are

almost indistinguishable.





The word science comes from the Latin "scientia," meaning knowledge. Science

refers to a system of acquiring knowledge. This system uses observation and

experimentation to describe and explain natural phenomena. The term science also

refers to the organized body of knowledge people have gained using that system. Less

formally, the word science often describes any systematic field of study or the

knowledge gained from it. What is the purpose of science? Perhaps the most general

description is that the purpose of science is to produce useful models of reality. Most

scientific investigations use some form of the scientific method. Science as defined above

is sometimes called pure science to differentiate it from applied science, which is the

application of research to human needs. Fields of science are commonly classified along

two major lines: Natural sciences, the study of the natural world & Social sciences, the

systematic study of human behavior and society.





Technology is a broad concept that refers to use and knowledge of tools and

crafts, and how these tools and crafts affect our ability to control and adapt to the

environment. In human society today, technology is a result of science and engineering.

A specific definition for the word "technology" is difficult to determine, because

"technology" can refer to material objects of use to humanity, such as machines,

hardware, or utensils, but can also encompass broader themes, including systems,

methods of organization, and techniques. The term can also either is applied generally or

to specific areas: examples include "construction technology", "medical technology", or

"state-of-the-art technology".

Science affects us all, every day of the year, from the moment we wake up, all day long,

and through the night. To make it clear how deeply science is interwoven with our lives,

just try imagining a day without scientific progress. Just for starters, without modern

science, there would be:







 No way to use electricity. From Ben Franklin's

studies of static and lightning in the 1700s, to

Alessandro Volta's first battery, to the key

discovery of the relationship between electricity

and magnetism, science has steadily built up our

understanding of electricity, which today carries

our voices over telephone lines, brings

entertainment to our televisions, and keeps the

lights on.









 No plastic. The first completely synthetic

plastic was made by a chemist in the early

1900s, and since then, chemistry has

developed a wide variety of plastics

suited for all sorts of jobs, from blocking

bullets to making slicker dental floss.









 No modern agriculture. Science has

transformed the way we eat today. In the

1940s, biologists began developing high-

yield varieties of corn, wheat, and rice,

which, when paired with new fertilizers

and pesticides developed by chemists,

dramatically increased the amount of food

that could be harvested from a single

field, ushering in the Green Revolution.

These science-based technologies

triggered striking changes in agriculture, massively increasing the amount of

food available to feed the world and simultaneously transforming the economic

structure of agricultural practices.

 No modern medicine. In the late 1700s,

Edward Jenner first convincingly showed

that vaccination worked. In the 1800s,

scientists and doctors established the

theory that many diseases are caused by

germs. And in the 1920s, a biologist

discovered the first antibiotic. From the

eradication of smallpox, to the prevention

of nutritional deficiencies, to successful

treatments for once deadly infections, the

impact of modern medicine on global health has been powerful. In fact, without

science, many people alive today would have instead died of diseases that are

now easily treated.









Scientific knowledge can improve the

quality of life at many different levels — from the

routine workings of our everyday lives to global

issues. Science informs public policy and

personal decisions on energy, conservation,

agriculture, health, transportation,

communication, defense, economics, leisure,

and exploration. It's almost impossible to

overstate how many aspects of modern life are

impacted by scientific knowledge.





Space technology is technology that is related to entering, and retrieving objects

or life forms from space. "Every day" technologies such as weather forecasting, remote

sensing, GPS systems, satellite television, and some long distance communications

systems critically rely on space infrastructure. Of sciences astronomy and Earth sciences

(via remote sensing) most notably benefit from space technology.



IT is the area of managing technology and spans wide variety of areas that include

but are not limited to things such as processes, computer software, information systems,

computer hardware, programming languages, and data constructs. In short, anything

that renders data, information or perceived knowledge in any visual format whatsoever,

via any multimedia distribution mechanism, is considered part of the domain space

known as Information Technology (IT). Communication & Banking system is largely

dependent on IT technology.

Educational technology is most simply and comfortably defined as an array of

tools that might prove helpful in advancing student learning. Educational Technology

relies on a broad definition of the word "technology". Technology can refer to material

objects of use to humanity, such as machines or hardware, but it can also encompass

broader themes, including systems, methods of organization, and techniques. Some

modern tools include but are not limited to overhead projectors, laptop computers, and

calculators.



In fact, we little know how much we owe to science & technology in the daily affairs of our

life. Modern science & technology is like Aladdin’s lamp. It does today what was

supposed to be impossible yesterday. Where it will end nobody can say, but this much

can be said that it will go on working & creating much more wonders in the days to come.
