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.
