If we look life 100 years ago,and compare that with the today’s life,we will notice that Science has dramatically changed human life.
With the dawn of the Industrial Revolution in the 18th century, the effect of Science on human life rapidly changed. Today, science has a profound effect on the way we live, largely through technology, the use of scientific knowledge for practical purposes.
Some forms of scientific inventions have changed our lives entirely. For example the refrigerator has played a major role in maintaining public health ever since its invention. The first automobile, dating from the 1880s, made use of many advances in physics, mathematics and engineering; the first electronic computers emerged in the 1940s from simultaneous advances in electronics, physics and mathematics. Today we have extra high- speed super computers with 100 % accuracy.
Science has enormous influence on our lives.It provides the basis of much of modern technology – the tools,materials,techniques,and sources of power that make our lives and work easier.The discoveries of scientists also help to shape our views about ourselves and our place in the universe.
Research in food technology has created new ways of preserving and flavoring what we eat.Research in industrial chemistry has created a vast range of plastics and other synthetic materials, which have thousands of uses in the home and in industry.
Synthetic materials are easily formed into complex shapes and can be used to make machines,electrical, and automotive parts, scientific, technical and industrial instruments, decorative objects, containers, packing materials and many other items.
The use of science in daily life has helped us a good deal in solving problems, dealing with the maintenance of health, production and preservation of food, construction of houses and providing communication and trans-portational (related to transport) facilities. With the help of Science we have controlled epidemics and much other kind of diseases. Now we know the basic structure of DNA and Genetic Engineering is conducting research to find out the right and correct Gene Therapy to overcome all the diseases.
Science has changed the people and their living, life style, food habits, sleeping arrangements, earning methods, the way of communication between people and recreational activities. All kinds of music systems, computer games, electronic video games, DVDs, cinema entertainment and communication have been brought to our door with the help of Science. The life of man was very different from what it used to be 100 years back. Science has given ears to the deaf, eyes to the blind and limbs to the crippled. Science has adequately, energetically and productively advanced, changed, civilized, enhanced and progressed human life. Science has brought sophistication to human life.
In short science has changed, improved, enhanced, modified and refined human life in all ways.
Today with the help of Science we can explain what was strange and mysterious for the people of the past. The Science of Genetics opening new doors of understanding the human gene and cell.
Now human beings have become more critical and less fearful than our fore-fathers and ancestors.
Two hundred years ago death rate among children was very high.In those days seven out of eight babies died before their first birthday. Now with the help of vaccines, medications and proper health care system life expectancy has improved.Now people live longer and safe lives as compared to 200 years ago. Biochemical research is responsible for the antibiotics and vaccinations that protect us from infectious diseases, and for a wide range of other drugs used to defeat specific health problems. As a result, the majority of people on the planet now live longer and healthier lives than ever before.
After that and up to the age of 12 one used to fall in a prey to diseases like small pox, measles, whooping- cough, scarlet fever and diphtheria.Now Science has defeated these diseases.
At a later stage again one was under constant threat of yellow fever, malaria, typhus, cholera, typhoid and influenza. Today we have vaccines and medical aid to cope with these health problems. Further research is underway to find out the causes and treatment of these and other diseases.
From one person the disease used to spread among the other people. It is called Epidemics. Now with the help of Vaccines and Medications we have defeated these diseases. But still Science has to do more research and has to fight with other arenas of diseases.
Life was uncertain. It was rare to see to somebody thirty years old because due to diseases many people died earlier than the age of thirty. These conditions were prevailing just a short while ago.
In everyday life, we have to communicate with different friends and relatives, various official people and for general purposes. And many people to be contacted can be at very far off distances. However, time and distance both have been conquered by Science. Whether we want to communicate or travel, both are possible quickly, briskly and expeditiously.
These days there are very little chances of babies catching diseases, because births normally take place in hospitals under the supervision of a team of specialist doctors. Science has invented vaccines for young babies to protect them against future life illnesses.
Young people are also given medical treatment in time and these days the man lives for about seventy years.
Science and scientific methods have helped in finding out the cause of disease and its prevention.
Sanitary condition in the past was deplorable. Now we have better sanitary systems.
The city streets were unpaved; there was no proper drainage system. Garbage and other refuse was seen everywhere. Pigs were seen wandering through the streets. People got water from filthy wells. Now filtered mineral water is available to overcome diseases. Solid waste management is not a problem now a days, it is the duty of the city municipal committees to manage and dump it with the latest machinery and equipments.
Now all these defects have gone. There is cleanliness everywhere. It is illegal to throw garbage into the streets. There is a proper drainage system and new and improved methods for solid waste management as it has been told earlier. There are separate departments that bother about sanitary condition of the towns.
A century ago for house hold purposes water was carried from wells outside in buckets. It sometimes proved injurious to human health. Moreover, it was insufficient for the daily needs. But now water filters have become a thing of common usage.
Now there is sufficient supply of water in cities. For example Los Angeles gets water through pipes from Colorado River, which is 340 miles away. This water is supplied to Los Angeles after the proper water filtration process.
With the help of science there is change in our food also. We get varieties of food. In the past, food could not be preserved. But now the quick freezing methods have made possible preservation possible.Due to modern technologies like dehydration and sterilization there is no chance of food poisoning. We get all kinds of fruits, meats and vegetables. Even those fruits and vegetables which are out of season.
Not only our eating habits are changed, but also there are improvements in our houses. Means of transport has also undergone a big improvement and change.
Science has also changed our attitudes. Superstitions have been discarded, because there is no scientific basis for them. Now people do not fear cloud thunders.
Now people no more believe that diseases are caused by evil spirits.
Astrology and fortune- telling have lost popularity as compared to 100 years ago. Nobody now fears black cats, broken mirrors and the number 13. Because science has proved that these kinds of fears are un-scientific and illogical.
Science has changed the longstanding false notions of the people, which are not supported by Scientific Facts.
Research in the field of science and technology has made people open-minded and cosmopolitan, because the Scientist does not like to travel on the beaten track and he always tries to find out new things, new explorations, new discoveries and new inventions.
Science has also brought medical equipments that help to save human life. The kidney dialysis machine facilitates many people to survive kidney diseases that would once have proved fatal, and artificial valves allow sufferers of coronary heart disease to return to active living.
Since the 1980s, lasers have been used in the treatment of painful kidney stones. Lasers are used when kidney stones fail to pass through the body after several days, it provides a quick and low-pain way to break up the stone and allow the stones to be easily passed through the body. This technique is called Lithotripsy.
Arthroscopic surgery is a technique using fiber optics to probe complex joints such as knee, shoulder, ankle and wrist to evaluate injury. It is a minimally invasive operation to repair a damaged joint; the surgeon examines the joint with an “arthroscopy” while making repairs through a small incision.
200 years ago nobody even knows that human body parts can be replaced or transplanted. Now kidney transplant is widely used to save human lives around the globe. Dr. Christian Bernard first of all invented the method of heart transplant. Eye transplant techniques are used in these days to see again this beautiful world, for those who have lost their eyes. These all are the blessings of Science.
Ultra-high-frequency (UHF) waves are allocated for variety of uses, including television, cellular phones, public safety radios, business radios, military aircraft communications, military radar, cordless phones, baby monitors, etc. So, whether someone is watching over-the-air TV, talking on cell phone, having police/fire/ambulance dispatched to an emergency they are experiencing, or having national airspace protected by military aircraft, they all are benefitting from the science that has allowed the use of UHF waves. Even it is used to treat some illnesses.
For communication, now we have fixed wire telephones, moveable wireless phone sets, cordless phones, mobile phones, wireless, video conferencing, Internet, Broad Band Internet, E-mail, Social Networks, Satellite Communication and many other ways to communicate. These all are blessings of Science. Today we are better aware of what is happening around the globe due to satellite television channels. The benign and benefits of science for human life are endless.
