Answer:
Scientific inventions have made life modern
the motorcar has made traveling easy and comfortable
the airplane can fly us over thousands of kilometers within hours
the railway engine can pull many railway carriages with hundreds of people and heavyweights
the tractor has made cultivation easy and quick
the radio and television provide us with different kinds of programs all the time
the VCR records TV programs, plays, and films to increase our knowledge and to entertain us
the printing press has made reading easy and fast through books, magazines, and newspapers
electronic watches and clocks
the computer
but many destructive inventions of weapons of war show the destructive use of science
on the whole, modern life is possible only because of science.
“The scientific advancement and inventions of yesterday are the stepping stones for further inventions and discoveries.”
Scientific inventions in different parts of the world have made our life modern. Let us have a look at some of these. Motorcar made traveling easy and comfortable. The bus and jeep also came to be used afterwards. The airplane can take us to places thousands of kilometres away within a few hours. The railway engine (the locomotive) can pull many railway carriages with hundreds of people and with heavy weights. The tractor has made cultivation very easy and quick. It can plow vast (large and wide) areas of land within a few hours. The tube-well engine easily lifts up water from under the surface of the earth quickly and in huge quantities.
On the radio, we can hear people speaking hundreds or thousands of kilometres away from us. On television, we can see pictures as well as hear the voices. Now artificial satellites and dish antennas (aerials) can help us to view TV programmes of even other continents. TV has, thus, brought about a revolution in sound, picture and colour communication. No wonder it has given all the pleasures of the cinema plus a variety of colourful programmes of the either world within the four walls of a room. We get connected to the planet earth as a whole as we watch the sliding pictures on the mini-screen.
Next, we shall get connected with different planets and planetary systems. Connected with TV is the DVD (digital video disc), which records data and plays it back. The Blu-ray Disc is the latest development in this connection.
Through the camera, and now the camera in the mobile phone, we can have pictures in. black and white and in color. We can make films with these pictures. In the printing press, we can print newspapers, magazines and books on a large scale (in a big way). It is because of the printing machines that we have so many books, magazines and newspapers. Electronic watches and clocks and electronic instruments are the result of modern scientific research. Different medicines prepared by scientists can cure most of our diseases.
The computer is one of the latest inventions that have made the calculation, designing, printing and planning very easy. We can advance swiftly in different fields like space exploration, engineering, banking, and so on because of its magical operations. The E-mail and fax systems in it have made the communication of written messages in actual form within seconds and minutes possible.
There are a great many “destructive” inventions in the form of weapons of war. Big guns, bombs, and poisonous gases are some of these. Atomic weapons and missiles are another categories of the massive killers. We should avoid using science for destructive purposes as much as possible. We have thousands of allopathic and homeopathic and even Greek (“Unani” or “Hakimi”) medicines and modern surgical methods and instruments. They are the outcome (result) of thousands of years of continuous scientific research and experimentation.
Life-saving drugs and surgical operation theatres in our well-equipped hospitals are a standing (permanent) witness to the power and usefulness of science. In the ultimate analysis, modern life is possible only because of the scientific inventions and discoveries around the world.
