Use Of Science And Technology For The Common Good

The uses of science and technology for the common good are numerous. Science and technology are the two great tools that the human species has to rapidly adapt to changes in its physical and psychosocial environment, producing well-being for the human community.

Other living species only have the natural evolutionary process, by which those with the most suitable environmental adaptations survive, but this is an extremely slow process and can take centuries.

Instead science and technology provide complements and extensions for the mind and body, which greatly enhance the possibilities of human beings as individuals and as a society. 

The environment meets vital needs, such as water, air, solar radiation, nutrients from plants and animals.
But it is also full of threats to life such as extreme weather changes, plagues, pests, epidemics, earthquakes, volcanoes, meteorites, extreme radiation and many more.

It is the use of science and technology that has allowed people to take effective advantage of the resources necessary for life, as well as mitigate the negative effects of natural hazards.

Relationship between science, technology and common welfare

For most the advantages of
technology, and they are not necessarily fancy objects. TO
Here is the wheel, that disk that rotates around an axis and allows heavy loads to be moved from one place to another. 

Another wonderful advance that is taken for granted is writing, which made it possible to record the customs, ideas and technologies of different civilizations through time. Subsequently, the printing press massified the dissemination of knowledge, the telephone allowed remote communication and the internet democratized access to information in a convenient and timely manner. 

For its part, science is in charge of studying, understanding and modeling natural phenomena. Although sometimes it seems to have no other benefit than satisfying the curiosity of scientists, it has been proven that all scientific knowledge leads, in the short or long term, to the invention of some new technology.

As an example we have the development of aviation, which was possible only after careful analysis and understanding of the flight of birds.

Beneficial applications of technology and science for the common good

1. Food preservation

It all began by elucidating whether living organisms appeared by spontaneous generation from non-living matter or whether the presence of some germ or spore was necessary for life to begin. 

It was thought that milk, by its nature, generated life, since bacteria and fungi appear in it. 

It was Luis Pasteur (1822 -1895) who demonstrated that if the milk and the air in the container that contains it are subjected to high temperature for a short time, and then allowed to cool isolated from the surrounding environment, microorganisms do not grow.

This discovery is what led to the technology

UHT

and packaging

TetraPak

that keep dairy products perfectly preserved for a long time and without the need for refrigeration.

2. Antibiotics

Around 1900, the British physician Alexander Flemming was studying a bacterium called

Staphylococcus

, growing it in agar plates , a gelatinous substance obtained from algae.

On one occasion, some dishes were contaminated with a fungus identified as

Penicillium

. Flemming noticed that a ring formed around the fungus on contaminated dishes, where its bacteria did not grow.

He rightly concluded that the fungus produced substances that inhibited bacterial growth.

This scientific discovery led to the isolation of the bacterial growth inhibitor substance, creating antibiotics, drugs necessary to combat infectious diseases of bacterial origin, such as syphilis, tuberculosis and many others.

3. The internet and blogs

The development of blogs has allowed the dissemination of ideas and knowledge
 Blogs like this have been possible thanks to the development of technologies such as the internet and web networks. Blogs serve to communicate ideas, knowledge and feelings, which can be beneficial to those who read them.

4. Instant messaging

WhatsApp

,

Messenger

,

T

elegram

and email
They are technologies that allow people to quickly communicate and contact, despite great distances.

This technology has been possible to scientific research carried out for decades, beginning with the discovery of electromagnetic waves, the development of electronics, the encoding and decoding of information in binary format, just to name a few of its foundations.

5. X-rays

It is one of the most widespread means of medical diagnosis. They serve to “look” inside the human body in a non-invasive way, without the need for surgery.

They were discovered in 1895 by physicist Wilhelm Roentgen when he was experimenting with discharge tubes. Roentgen observed that, even when these tubes were completely covered so that they did not emit light, something that emanated from them was capable of veiling the photographic plates.

In addition, the mysterious rays that Roentgen baptized with the name of X-rays, were capable of passing through materials and even the human body. 

Roentgen took the first X-ray when he put his wife’s hand between one of his discharge tubes and a photographic plate, gazing at the detailed bone configuration in amazement.

This discovery was the basis for all technological development in medical diagnostic X-ray systems. Of the most advanced devices, based on X-ray technology, is the

Computed Axial Tomography (CT)

.

6. Gunpowder

Gunpowder sparked a revolution in weapons technology and completely revolutionized the way of warfare. Civilizations that had this technology were able to subdue others that did not. Therefore, p
For better or for worse, gunpowder-based technology is what has literally forged today’s societies by fire. 

On the other hand, gunpowder and its derivatives such as TNT, have been used effectively for the extraction of minerals that modern civilization requires.

7. The electric motor

Without the investigation of electromagnetism, the development of electric motors would not have been possible. Much of the machines in homes and industries are based on the electric motor.

Likewise, everything seems to indicate that the cars of the future will be based on this type of engine.

8. The fire

Humanity has two great moments that are very dissimilar to each other: before and after the technology of fire production and control. Civilizations that did not have fire were exposed to extremely cold climates and to the attack of many predators, so they practically succumbed.

Many claim that the H

as sapiens

it is the dominant species thanks to the technology of fire. 
At the pinnacle of fire control technology we have the internal combustion engine, thanks to which today’s civilization has developed.

9. Agriculture and the plow

Before the invention of agriculture, humanity depended on what nature had to offer. Until he discovered agriculture, and later he invented the plow, allowing the increase in crops and crops, with the consequent increase in population.

10. Electricity

The understanding, control and production of electricity is what has made the development of contemporary and current civilization possible. Practically, everything that contributes to the well-being of people involves electricity in one way or another: cities, devices, cars, industries, hospitals, banks, homes and more, everything depends on the flow of charged particles for its operation.
