Invention is the activity of investigating
and finding a new method of achieving something, or a new device
for use by people, or a new principle or concept or law that
governs some physical quantities. An invention is a qualitative jump over
the existing implementation. Inventions are the ones that made man
progress from cave man to a a space voyager.
1. Surgery and Antibiotic medicines
Antibiotics are the best inventions. As people fall sick due to many viral infections, the antibiotics are able to kill the viruses. Had there been no anti biotics, many people would be dying every year.
Surgery is the technique that helps people to get back to their normal condition, after being ill due to different diseases. Surgery enables many women to deliver babies in safe and reliable way. There were many deaths of people, as they could not be operated in safe conditions, and with proper technology, long ago. Once people were hit by a disease or injured in a war or otherwise, they had to die. Now surgery makes it possible to operate a severely injured person or ill person.
Among the ancient inventions, the invention of a Language
and its script as a medium of communication is the most important invention.
With out a means to express ones views either verbally or by means of writing,
human beings would have been as good as the cave man.
The language made a person do some thing in a life
time and pass it on to the next generation. The knowledge and culture
gained by one generation became the starting point for another
generation. Hence we progressed. We had books because we had a
language to write. Without reading books, even the great scientists could
probably not invent much.
The invention of language has allowed a person to
think better, improve culture, further enabled many discoveries and
inventions. Language enabled people to live together harmoniously and
establish family and society life. A language is very essential for the
development of a civilization.
The rotating wheel is one of the most important inventions
of the ancient man. A wheel is the basic part needed to transport a
person or a good across from one location to another. Without a wheel, pyramids,
Eiffel tower, Taj mahal, and perhaps even our own house could probably be not
built. People had to walk and carry every load by themselves or on
animals. Many people would be doing labour work still, with out a wheel.
Many industries depend on rotation of wheels to convert movement in
one direction to another. Electricity is generated only by
rotating turbines (wheel shaped cylindrical) in a circular
path. Wheel is the invention that makes use of circle as a concept.
3. Semiconductor based transistor
The invention of a semiconductor transistor device
by Bardeen, Brittain and William Schockley has lead us to the development of
most sophisticated computers, laptops, cell phones, calculators, appliances,
weapons, gadgets etc. In fact, this twentieth century advanced invention
is the basis for every electronic device used today.
With out a transistor device, there is no electronic
control. Half the total number of jobs in the world would not be there.
Such a fast growth in the world would not be possible at all in the last fifty
years. This electronic device is controlling every other device
now. In fact, human being is not controlling the electronics any
more. It is the electronic controls that are controlling human beings.
4. Electricity and electric lamp
Electricity is most essential for anyone to live in this
modern world. Since a person wakes up in the morning till the person
sleeps, everything is linked to electricity. Most of the modern gadgets
work on using current. The invention of lamp by Thomas Alva Edison is
significant in making the night as useful as the day. Otherwise, we would
not be able to do anything in the night.
Without electricity and light we will not be able to put a step
forward. We are used to these inventions so much. . A newspaper in
the morning, electric stove, lighting, fan, water heater, battery, radio, TV,
AC, etc. all things we make use of depend on electricity and the concept of
