Science is the systematic
study of laws of nature, human being, animals, environment, plants, space etc.
for their physical and chemical properties. Science
establishes the relationships (and laws) among various substances and physical
quantities in the Universe.
Science is very relevant to all of us,
as our careers in future depend on progress in sciences. Sciences form the
principles and idea for a technology and Engineering is the process to build
new products using that technology. All of us need products for
tries to make an improved product, or service using a more suitable method or
substance or law. Technology is based on sciences
and depends on engineering to come to people. The aim is always to
improve the quality and usability of the product and decrease the cost of the
product or service. A technology that is not yet feasible, necessary or
economical at present, will perhaps be feasible and economical later in future.
Technology is a standardized method of
realizing a formula using a class of materials, and a particular technique
related to precision or production. Suppose a particular technology is employed
in manufacturing & engineering of electricity generation or
distribution. If a new semiconductor material better than Silicon is
found, or, a more precise way of making a more complex electronic chip is
known, then using that will be the new technology. Coal based heating in
electric power generation plant uses traditional technology. Atomic power
plants use a more advanced nuclear fission process based method to heat
water. So there is a leap in technology to generate a long term based
safer, cheaper electric power. The hazards posed by newer technology are problems
that advanced technologies have to solve.
Products are meant for people or the rich and creamy layer of the society. People
accept the product and its technology or reject it depending on convenience of
use and cost. Then technology is improved to next generation to bring new product to
satisfy the people.
The Science (study and research), Technology (newer
and improved), Engineering and Society (use, accept/reject) cycle continues
for ever in the world.
When people used to burn coal and wood for cooking in
kitchen, there were many problems. New technologies brought in LPG
stoves, Biogas based heating, electric stoves, electric cookers, microwave
ovens and solar cookers. Each product utilizes a new technology (method,
raw material, design) and gives better service at higher
efficiency, convenience, at lower cost to the people, than the earlier
technology. This is what we mean by technology for people.
Improvements in medical
diagnosis and treatments have been made through many generations of
technology. A disease that used to take months to diagnose and cure are
now diagnosed and cured within hours or days.
Long ago the facility of communication with relations
and friends was difficult, time consuming and depended on weather and on other
people. Then postal services, fixed telephone, telegrams, were available.
Later cordless and mobile phones were available. Now a more interactive
web based services and phones are combined in one gadget.
There are some
harmful technologies that cause pollution of air and water, cause global
warming, produce waste that requires special place to dump it and careful
handling. Unfortunately sciences and
technologies have produced chemical and biological weapons. That is not right. Eco-friendly technologies
are the need of the hour.
science will help build better houses, gadgets, more convenient,
safe lifestyle, simpler and safer transport for us all. The people can
live better, even though it may be costlier. Huge amounts are being invested on
scientific researches. More and more jobs and professions may evolve due
Technologists make use of scientific
inventions and developments, and attempt to bring in continuous
improvement in the lives of people in the world through continuous
improvement in products and services. I
hope we all will be part of it and encourage positively eco-friendly sciences
and technologies. Let us take oath for it.
Thank you all for listening to me attentively and silently.
