What are Science, Technology and society, and why should people want to study
and learn it? Why should students, teachers, researchers and other professionals have
interest in the subject? Primarily, we need some background and understanding of the
significance of science and technology in the living past and their importance in the
modern world (Mosteiro,2004)

The Nature of Science
Prof. Pacifico U. Payawal

“Science is the interpretation of nature and man is the interpreter.”(G. Gore 1878)1
“Nature, with all her irregularities, might have been just as real even if there were no men
to observe and to study her. But there could have been no science without human beings,
or beings like them. It is the spirit of man brooding over the stream of natural events that
has given birth to science.” (A Wolf 1925).2

“Science is the attempts to make the chaotic diversity of our sense experience correspond
to a logically uniform system of thought.” (A. Einstein 1940)3

What is Science? According to the definitions given by gore, Wolf, and Einstein, the
subject matter of science is nature. Every physical entity in the extra terrestrial and
terrestrial environment is a component of nature. The galaxies, the stars in the galaxy, the
planets and their moons, the asteroids and the comets, the air, water, and soil; the plants

and the animals, they are physical entities of Mother Nature. We are conscious of
nature’s reality because of the stimuli emanating from these entities which our sense

Nature is very complex. The multitudes of entities comprising nature, and their complex
interactions, make nature innately complex. Therefore, the totality of stimuli emanating
from her is intuitively chaotic. Science represents the attempt of man to put order to this
chaotic perception of nature. Thus, Albert Einstein 3

defined science as “Man’s attempts
to make the chaotic diversity of his sense experience correspond to a logically uniform
system of thought.” And indeed, as G. Gore1 wrote,” Science is the interpretation of
nature and man is the interpreter.” And as A. Wolf2 opined,

” It is the spirit of man
brooding over the stream of natural events that has given birth to science,” Clearly,
science is the product of human curiosity.

Why are we curious? It is almost an instinct for us humans to try to understand what our
senses perceived because of our highly developed mental skills. These are the mental
skills to observe, infer, measure, classify, experiment, and to communicate. Through the
ages, our ancestors learned to use these skills in a methodical manner to investigate the
‘how,’ the ‘why,’ and the ‘when’ of natural events. This methodical manner to our mental
skills to satisfy human curiosity is the scientific method.

Using the scientific method, generation after generation pf scientist gradually discovered
the natural laws that govern natural processes. As each generation described with an ever
increasing accuracy the events and circumstances that prevail in nature, what was once
perceived as chaotic becomes rational, and man saw the unity in the diversity of nature.
In other word, the scientific endeavors spanning several generations yielded a number of
natural laws. These laws reduce natural events in nature to orderly predictable events.

What sets the limitation of science? Science is a product of the human senses and the
human mind and that is why there could be no science in the absence of an intelligent
being like a human or any other intelligent creature like him. And therein lies the
limitation of science; the limitation of the human senses and the limitation of the human
mind. We can not investigate what our senses cannot perceive, and we can not explain
beyond what our human mind can understand. As a matter of fact, the optical and the
electron microscope, the optical and radio telescopes, and all the other new scientific
instruments are but the result of our attempts to extend our sense of perception.

How does science operate? Science is a self correcting and self-generating human
activity. Using the scientific method, each generation of scientist develop explanations of
natural phenomena but at the same time, within the same generation, there are scientists
who question the validity of the proposed explanations. And within the same generation,
there are scientists who arrive at some new observations which lead to the identification
of new and heretofore undescribed phenomena. In this manner science is self-correcting
and self-generating, it is never stagnant.

How does the Scientific Method operate? The scientific method is a mental process
which serves as the “tool” of scientist with which new discoveries are made Although the
scientific method is traditionally characterized as a rigid mental process consisting of (a)
observation, (b) problem identification, (c) hypothesis formulation, and (d) drawing of
conclusions as to the possible validity if the prediction, scientists are not in general
agreement as to exactly what constitutes scientific procedure.

In reality, this rigid process called the scientific method did prove useful in some
particular instances, like in biology where the problem is amenable to experimental
manipulation. But in some other cases, the problem may not be amenable to controlled
manipulation, like in the geological process of volcanic eruption and mountain building.
Under such unmanageable events, the traditional scientific procedure is unrealistic.

What seems to be common to all scientific investigations is that scientific procedure
involves postulating and testing hypothesis. The testing part may or may not strictly
involve experimentation but accurate observations. In other words, not all scientists
necessarily conduct experiments to prove hypotheses.

In the development and proving of hypotheses, scientists use inductive and deductive
logic, but they do not tend to think exclusively in one way or the other at different times.
In practice, they use the interplay of inductive and deductive logic. Inductive logic
proceeds from the specifies and arrives at a generalization. On the contrary, deductive
proceeds from the general to the specific. To be sure, the following examples are in order.

Inductive logic involves arriving at a probable conclusion based on several samplings.
Suppose that a person tasted a green mango and found it sour and slightly tangy to the
taste buds. Then he subsequently tasted 24 other mangoes and found the same result.
Based on the these 25 samplings, he may then conclude that all green mangoes are sour
and tangy to the taste. Inductive logic thus proceeds from several specific observations to
a generalization. Most of the major theories are arrived at I this manner. For example, the

Cell Theory, the Theory of Biological Evolution by Natural Selection, and the theory of
plate tectonics, all these are generalizations arrived at by inductive reasoning.

Deductive logic proceeds from a generalization to specifics. For example, after testing 25
green mangoes and finding them sour and tangy, one may hypothesize that the next
mango he will taste will be sour and tangy. This kind of reasoning is used to formulate a
new hypothesis after a generalization. For example, the generalization that all green
mangoes are sour and tangy was arrived at after 25 green mangoes. From this
generalization, the scientists may further formulate a new hypothesis using deductive
logic. If 25 green mangoes are sour and tangy, then the next green mango I will taste
should be sour and tangy. If indeed the mango tasted sour and tangy, then the validity of
the original generalization has gained greater probability (or credibility). Thus, the
scientific procedure; or science progress by the interplay of inductive and deductive

It should be pointed out however that inductive generalization never attain absolute
certainty. They only attain higher degrees of probability. For example, the probability
that all green mangoes are sour and tangy based on 25 samples has a lower degree of
certainty than if the sample size is increased to 20 mangoes. But even if the sample size is
increased tom 1000 green mangoes, still there is no absolute certainty that all green
mangoes are sour and tangy. The number of green mangoes is infinite and no one can be
absolutely certain the next green mango to be tasted will not be sweet. Thus science can
only seek for the most probable truth and never for the absolute truth. A.W. Ghent
developed a conceptual scheme to illustrate the role of inductive and deductive logic in
the conduct of scientific investigation.

The scheme shows that scientific procedure begins with an educated guesswork about the
probable explanation to a perceived problem. The guesswork is an educated guess based
on previously known facts related to the problem. The scientists then make a prediction
based on the guesswork; this is the hypothesis. Thus, hypothesis formulation involves
deductive reasoning and goes this way,’ If(an assumption is made based on the
guesswork), then (the prediction that is expected if the assumption is valid). The
prediction is actually the anticipated event to happen if the assumption is correct.

Experiments or factual observations are then made to prove the validity of the hypothesis.
Usually, the result of the experiment/observations may overlap only slightly with those
predicted by the hypothesis. Nevertheless, the result allows the investigator to arrive

inductively at new and more realistic concept (guesswork) about the explanation as the

From the improved guesswork, a new and more realistic hypothesis is made by deductive
logic. Experimentation/observations are then made to test the new hypothesis which
normally results in a much improved guesswork. Thus, the interplay of deductive and
inductive reasoning contributes to increasingly realistic concept of explanation to a
problem. I other words, the interplay yields increasingly reliable factual knowledge less
and less of guesswork.

Is technology a part of science? The little we understood about nature we were able to
use to develop technologies that enabled us to survive and progress; and to be the most
dominant animal species on earth. But technology is not science. Science only seeks to
understand nature, no more no less; technology is but the application of what science has
discovered, for better for worst. That is why usefulness is not a prerequisite to the
generation of knowledge; on the contrary, usefulness is the primary prerequisite to the
generation of technology.


On the same view, technology is defined as both a PROCESS and a PRODUCT
    a. It is the application of science.
    b. The practice, description, and terminology of applied sciences.

    h. It is characteristically calculative and imitative, tends to be
    dangerously manipulative.
    i. Form of human cultural activity.
    a. A system of know-how, skills, techniques and processes.
    b. It is like a language, rituals, values, commerce and arts, it is an
    intrinsic part of a cultural system and it both shapes and reflects the
    system values.
    c. It is the product of the scientific concept.
    d. The complex combination of knowledge, materials and methods.
    e. Material products of human making or fabrication.
    f. Total societal enterprise.

    to produce, distribute, install, maintain or improve goods and services needed
    to satisfy human needs.
  4. Is an interdisciplinary field of study that seeks to explore and understand the
    many ways that modern science and technology shape modern culture, values
    and institutions, and how modern values shape science and technology.

    ultimate Good, and Truth. It cannot deny nor confirm the existence of God,
    soul, heaven and other uncertainties.
  11. Metaphysical concerns. Immaterial and transcendental nature is beyond the
    grasp of scientific inquiry. It cannot speak to issues of ultimate origin,

  21. Can not fully explain what is in the mind of a person.
    Technological leadership is vital to the national interest of any developing and
    developed nation. As we enter the twenty-first century, humans ability to harness the
    power and promise of leading-edge advances in technology will determine, in large
    measure, national prosperity, security, and global influence, and with them the standard
    of living and quality of life.

  28. Technology is the single most important determining factor in sustained
    economic growth, estimated to account for as much as half a nation’s
    growth over the past 50 years.
  29. Technology is transforming the very basis of competition-enabling small
    businesses to perform high-quality design and manufacturing work that
    previously required the resources of big business, while allowing big
    businesses to achieve the speed, flexibility, and proximity to customers
    that were once the sole domain of smaller firms.
  30. Technology provides the tools for creating a spectacular array of new
    products and new services.
    Technology and the Quality of Life
    New technologies are improving the quality of life. These are seen in:
  31. Medical research in pharmaceuticals, biotechnology, and medical devices
    helps us lead healthier lives and offers new hope for the sick.
  32. Environmental research brings better monitoring, prevention, and remediation
  33. Advanced monitoring and forecasting technologies – from satellites to
    simulation – are helping to save lives and minimize property damage by
    severe weather.
  34. Sophisticated traffic management systems for land, sea, and air transportation
    enable the smooth and timely movement of more people and goods.
  35. Agricultural research is producing safer, healthier, and tastier food products.
