Using the scientific method
In this highly
informative essay Darrel Barnad and Lon Edwards have presented the services of
science o humanity along with the comparative study of past and present. They
tell the readers about the revolution brought by science in the fields of
medicine, sanitation, food preservation and day-to-day human beliefs and
attitude. To confine the blessings of science is to attempt the impossible.
Here, only following advantages of science are discussed.
Two hundred years ago, diseases were quite common. Most of the newly born
babies used to die on the very first year of their life. Those who survive
during that year had to face severe diseases like smallpox, diphtheria, measles
and whooping cough etc. In the past, once an epidemic broke out, it affected the
whole community. Unfortunately, it resulted in wholesale deaths; the average age
of human being was forty years. Now, by using scientific method, the situation
has much improved and human being is able to control over many fatal diseases
very successful. Today babies ate born in the hospitals where there is little
likelihood of getting a disease. The average age of human being has also
increased almost to seventy years. Human Being can prevent himself form many
dangerous diseases by using scientific method in their diagnosis, treatment and
One hundred year ago, the sanitary condition in sane of the largest
cities of the world was far from good. The streets were narrow and unpaved.
There was no proper system for the drainage of dirty water. Heaps of garbage was
commonly seen in the streets. The supply of water for drinking and for other
purposes was not satisfactory. As a result, people had to remain dirty. Every
body knows that unsanitary conditions con cause many fatal diseases. Now by
using scientific method, the sanitary condition has been improved largely. The
streets are paved and are cleaned regularly. It is unlawful to throw garbage in
the streets. Dirty water and waste materials are carried through closed pipes to
distant places for disposal. Water for drinking and other purpose is supplied in
a large quantity through closed pipes. In this water, chances of presence of
germs have been greatly reduced. No doubt, this is all due to the application of
FOOD AND BETTER FOOD.
By using the scientific method, human being has considerably overcome
food shortages. He has now more and better food than the people of the past. In
the past, we knew nothing about the importance and preservation of food. It has
been proved that is healthful to eat many kinds of food. Previously, the food
was preserved by ordinary methods and unskillfully. Due to this, sometimes, the
preserved food materials got rotten and poisonous. Now, various kinds of met,
fruits, vegetables and fish are preserved by quick freeze method with the help
of machines. By this process, these remain delicious and nutritious for a long
time. This type of food can also be taken to for-off places. Food suck as milk,
apples, eggs, etc. are preserved by another method called dehydration (taking
out water). This is why; modern human being enjoys a better standard of living
than the people of the past.
Our ancestors were narrow-minded because they could not acquire scientific knowledge. They believed in baseless thing that had been held true for a long time. Astrology and fortune-telling usually played and important role in the lives of the people. They also believed in the broken mirrors and the number 13. Now, science has proved that there is always a good nature reason to every happening that comes to the people. Science has made people open-minded. This is why; the conclusions of today are not taken as final. The people are more willing to look for new truths.
