Essay on the science and war
science and war
Science and war are two different terms but they are found to have been deeply related. The existence of war initiated before the invention of scientific discoveries which are nowadays used as the means of war. The mode of war has been made destructive due to the misuse of scientific discoveries and deadly devices.
It is said that the modern scientific discoveries have made everything more comfortable. Nowadays we can travel around the world in twenty-four hours. We can enjoy everything sitting at one home. Due to the invention of scientific discoveries, we have achieved complete access to each of the corners of the world. On the other hand, the means of scientific discoveries are willingly misused for the destruction of human civilization; no doubt, it’s the worst aspect of the science and technology. The discoveries of science and technology cannot be said to be completely responsible for making the mode of war more destructive because no scientific discoveries are destructive themselves if we use them properly.
Due to the misunderstanding among or between the countries along with the development of battle instruments, wars break out. The powerful countries try to take the whole world under their control. But it is not accepted by other countries. So due to the so called supremacy of powerful countries and the feeling of self-dignity of other countries, wars automatically break out; and they ultimately invite catastrophic consequences.
Science is not the cause of war but it absolutely functions as a promoter. The means of scientific discoveries are misused as the weapons of war human beings. Nowadays various kinds of fatal weapons of wars are widely used all over the world. So an intricate relation between science and war exists at the root of modern battles. The deadly devices and discoveries hostile to put out rave an end through the tremendous misuse of scientific deceived; for instance two entire cities in Japan were completely ruined as the result of atom bomb.
Although science doesn’t play the prime role to break out wars, it has undoubtedly and unquestionably promoted and intensified the mode of wars due to the deadly discoveries of it. Modern wars and deadly scientific discoveries have emerged inextricably. Therefore the relation between science and war has been widened and promoted.

Essay on Laser Technology
Laser Technology
Science and technology has provided us numerous miraculous
discoveries and devices. Lasers are is most modern achievements. Lasers are
discoveries as the devices which produce pure and intense beams of light or
radiation. They were invited in 1960. At the time of invention, nobody knew
what to do with them, but nowadays they are widely used in many sectors
tremendously.
Lasers are widely used in the field of industry. They are
used in cutting clothes, piercing leather and even substances like diamond and metals,
and cutting bricks and granite. Similarly, they are also used in welding, they
can also be used in transport and communication; for example, they are used
instead of cables in telecommunication, and they are used in flight
simultaneous to train pilots. Thus laser are enormously used in the field of
industry, transport and communication.
In the field of medicine, lasers have made a revolution.
Lasers are used to destroy the single cell of living tissues in the treatment
of cancer. Doctors have been using lasers instead of surgical knives in major operations.
Similarly, skin blemishes can be removed by the help of lasers. Lasers can help
us in pollution control. They are useful for measuring the size of pollutant
particulars in the air. They can possible be used to clear up oil slices on the
surface of the seas. They can also be used for measuring the distance between
two objects, such as between the moon and the earth. Thus they are used in the
field of medicine, pollution control and measurement. Because of the advantages
mentioned above, lasers are completely beneficial.
Unfortunately, lasers can be used as the means of war. It is
the misuse of them. They can be mercilessly used to kill human beings; that’s
why they are also called death rays. In the war, they are used in guiding
missiles and finding range for gunners. It is the exploitation of lasers, and
in the sense, they invite demerit and ruins.
Although lasers can have both advantage and disadvantages,
they are miraculous achievements of science and technology. If they are
properly used for the construction of human civilization they cannot invite any
fatal disasters; but if they are misused, they certainly lead us to failures
and destruction. It is wise of human beings not to invite any collision
courses of human civilization.
Essay on The value of science

root of modernization. Nowadays, we can live comfortably by utilizing the gifts
if science and technology.
Human progress completely depends on the discoveries of
science and technology. Many miraculous devices have been invited. We use them
for our comfortable life. All the sector of human activities is directly
influenced by science and technology. Our food, water, shelter, clothing, modes
of transport and communication, health, application of energies etc. have been
changed and improved as the gift of scientific discoveries.
