What is SCIENCE?

Answer 1

Science in the broadest sense refers to any knowledge or trained skill, especially (but not exclusively) when this is attained by verifiable means.[1] The word science also describes any systematic field of study or the knowledge gained from such study. In a more restricted sense, science refers to a system of acquiring knowledge based on empiricism, experimentation, and methodological naturalism, as well as to the organized body of knowledge humans have gained by such research.

In a more restricted sense, science refers to a system of acquiring knowledge based on empiricism, experimentation, and methodological naturalism, as well as to the organized body of knowledge humans have gained by such research. This article focuses on science in the latter sense.

Scientists maintain that scientific investigation must adhere to the scientific method, a process for evaluating empirical knowledge which explains observable events in nature as a result of natural causes, rejecting supernatural notions.

Fields of science are commonly classified along two major lines:

* Natural sciences, the study of the natural phenomena;
* Social sciences, the systematic study of human behavior and society.

Mathematics has both similarities and differences compared to other fields of science, and is sometimes included within a third, separate classification, called formal science. Mathematics is similar to other sciences because it is a rigorous, structured study (of topics such as quantity, structure, space, and change). It is different because of its method of arriving at its results. Mathematics as a whole is vital to the sciences — indeed major advances in mathematics have often led to major advances in other sciences. Certain aspects of mathematics are indispensable for the formation of hypotheses, theories and laws in discovering and describing how things work (natural sciences) and how people think and act (social sciences).

Science as defined above is sometimes termed pure science to differentiate it from applied science, the application of scientific research to human needs.

Etymology

The word science comes from the Latin word scientia for knowledge. The Indo-European root means to discern or to separate, akin to Sanskrit chyati, he cuts off, Greek schizein, to split, Latin scindere, to split. From the Middle Ages to the Enlightenment, science or scientia meant any systematic or exact recorded knowledge. Science therefore had the same sort of very broad meaning that philosophy had at that time. In some languages, including French, Spanish, Portuguese, and Italian, the word corresponding to science still carries this meaning.

From classical times until the advent of the modern era, philosophy was divided into natural philosophy and moral philosophy. In the 1800's the term natural philosophy gradually gave way to the term natural science. Natural science was gradually specialized to its current domain, which typically includes the physical sciences and the biological sciences. The social sciences, inheriting portions of the realm of moral philosophy, are currently included under the auspices of science as well, to the extent that these disciplines also use empirical methods. As currently understood, moral philosophy still retains the study of ethics, regarded as a branch of philosophy and one of the three classical normative sciences.[2]

Scientific method

Main article: Scientific method

Scientists use model to refer to a description of something, specifically one which can be used to make predictions that can be tested by experiment or observation. A hypothesis is a contention that has been neither well supported nor yet ruled out by experiment. A theory, in the context of science, is a logically self-consistent model or framework for describing the behavior of a certain natural phenomena. A theory typically describes the behavior of much broader sets of phenomena than a hypothesis — commonly, a large number of hypotheses may be logically bound together by a single theory. A physical law or law of nature is a scientific generalization based on a sufficiently large number of empirical observations that it is taken as fully verified.

The scientific method provides an objective process to find solutions to problems in a number of scientific and technological fields. Often scientist/s have a preference for one outcome over another, and it is important that this preference does not bias their interpretation. The scientific method attempts to minimize the influence of a scientist's bias on the outcome of an experiment. This can be achieved by correct experimental design, and thorough peer review of experimental design as well as conclusions of a study.

Scientists never claim absolute knowledge. Unlike a mathematical proof, a proven scientific theory is always open to falsification, if new evidence is presented. Even the most basic and fundamental theories may turn out to be imperfect if new observations are inconsistent with them. Critical to this process is making every relevant aspect of research publicly available, which permits peer review of published results, and also allows ongoing review and repeating of experiments and observations by multiple researchers operating independently of one another. Only by fulfilling these expectations can it be determined how reliable the experimental results are for potential use by others.

Isaac Newton's Newtonian law of gravitation is a famous example of an established law that was later found not to be universal - it does not hold in experiments involving motion at speeds close to the speed of light or in close proximity of strong gravitational fields. Outside these conditions, Newton's Laws remain an excellent model of motion and gravity. Since general relativity accounts for all the same phenomena that Newton's Laws do and more, general relativity is now regarded as a better theory.

Philosophy of science

Main article: Philosophy of science

The philosophy of science seeks to understand the nature and justification of scientific knowledge, and its ethical implications. It has proven difficult to provide a definitive account of the scientific method that can decisively serve to distinguish science from non-science. Thus there are legitimate arguments about exactly where the borders are. There is nonetheless a set of core precepts that have broad consensus among published philosophers of science and within the scientific community at large. (see: Problem of demarcation)

Science is reasoned-based analysis of sensation upon our awareness. As such, the scientific method cannot deduce anything about the realm of reality that is beyond what is observable by existing or theoretical means. When a manifestation of our reality previously considered supernatural is understood in the terms of causes and consequences, it acquires a scientific explanation.

Resting on reason and logic, along with other guidelines such as Occam's Razor, which states a principle of parsimony, scientific theories are formulated and the most promising theory is selected after analysing the collected evidence. Some of the findings of science can be very counter-intuitive. Atomic theory, for example, implies that a granite boulder which appears a heavy, hard, solid, grey object is actually a combination of subatomic particles with none of these properties, moving very rapidly in space where the mass is concentrated in a very small fraction of the total volume. Many of humanity's preconceived notions about the workings of the universe have been challenged by new scientific discoveries. Quantum mechanics, particularly, examines phenomena that seem to defy our most basic postulates about causality and fundamental understanding of the world around us.

Goals of science

Science continually seeks to gain increased understanding and, where appropriate, the possibility for control of many specific aspects of the physical world. Its successes in achieving this goal stem directly from its ability to elucidate the foundational mechanisms which underlie nature's processes. Here, an image of "artificial" bioluminescence which has been induced in a tobacco plant by the use of genetic engineering.

The underlying goal or purpose of science to society and individuals is to produce useful models of reality. It has been said that it is virtually impossible to make inferences from human senses which actually describe what “is.” On the other hand, people can form hypotheses based on observations that they make in the world. By analyzing a number of related hypotheses, scientists can form general theories. These theories benefit society or human individuals who make use of them. For example, Newton's theories of physics allow us to predict various physical interactions, from the collision of one moving billiard ball with another, to trajectories of space shuttles and satellites. Relativity can be used to calculate the effects of our sun's gravity on a mass light-years away. The social sciences allow us to predict (with limited accuracy for now) things like economic turbulence and also to better understand human behavior and to produce useful models of society and to work more empirically with government policies. Chemistry and biology together have transformed our ability to use and predict chemical and biological reactions and scenarios. In modern times though, these segregated scientific disciplines (notably the latter two) are more often being used together in conjunction to produce more complete models and tools. One goal of science is to explain and utilize multiple known phenomenon with one theory or set of theories.

Despite popular impressions of science, it is not the goal of science to answer all questions. The goal of the sciences is to answer only those that pertain to perceived reality. Also, science cannot possibly address nonsensical, or untestable questions, so the choice of which questions to answer becomes important. Science does not and can not produce absolute and unquestionable truth. Rather, science tests some aspect of the world and provides a reasonable theory to explain it.

Science is not a source of subjective value judgements, though it can certainly speak to matters of ethics and public policy by pointing to the likely consequences of actions. What one projects from the currently most reasonable scientific hypothesis onto other realms of interest is not a scientific issue, and the scientific method offers no assistance for those who wish to do so. Scientific justification (or refutation) for many things is, nevertheless, often claimed. Of course, value judgements are intrinsic to science itself. For example, scientists value relative truth and knowledge.

In short, science produces useful models which allow us to make often useful predictions. Science attempts to describe what is, but avoids trying to determine what is (which is for practical reasons impossible). Science is a useful tool. . . it is a growing body of understanding that allows us to contend more effectively with our surroundings and to better adapt and evolve as a social whole as well as independently.

Individualism is a tacit assumption underlying most empiricist accounts of science which treat science as if it were purely a matter of a single individual confronting nature, testing and predicting hypotheses. In fact, science is always a collective activity conducted by a scientific community. This can be demonstrated many ways, perhaps the most fundamental and trivial of which is that scientific results must be communicated with language. Thus the values of scientific communities permeate the science they produce.

For a large part of recorded history, science had little bearing on people's everyday lives. Scientific knowledge was gathered for its own sake, and it had few practical applications. However, with the dawn of the Industrial Revolution in the 18th century, this 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 technology have become so well established that it is easy to forget the great scientific achievements that they represent. The refrigerator, for example, owes its existence to a discovery that liquids take in energy when they evaporate, a phenomenon known as latent heat. The principle of latent heat was first exploited in a practical way in 1876, and the refrigerator has played a major role in maintaining public health ever since (see Refrigeration). The first automobile, dating from the 1880s, made use of many advances in physics and engineering, including reliable ways of generating high-voltage sparks, while the first computers emerged in the 1940s from simultaneous advances in electronics and mathematics.

Other fields of science also play an important role in the things we use or consume every day. Research in food technology has created new ways of preserving and flavoring what we eat (see Food Processing and Preservation). 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 machine, electrical, and automotive parts, scientific and industrial instruments, decorative objects, containers, and many other items.

Alongside these achievements, science has also brought about technology that helps save human life. The kidney dialysis machine enables 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. 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 combat specific health problems. As a result, the majority of people on the planet now live longer and healthier lives than ever before.

However, scientific discoveries can also have a negative impact in human affairs. Over the last hundred years, some of the technological advances that make life easier or more enjoyable have proved to have unwanted and often unexpected long-term effects. Industrial and agricultural chemicals pollute the global environment, even in places as remote as Antarctica, and city air is contaminated by toxic gases from vehicle exhausts (see Pollution). The increasing pace of innovation means that products become rapidly obsolete, adding to a rising tide of waste (see Solid Waste Disposal). Most significantly of all, the burning of fossil fuels such as coal, oil, and natural gas releases into the atmosphere carbon dioxide and other substances known as greenhouse gases. These gases have altered the composition of the entire atmosphere, producing global warming and the prospect of major climate change in years to come.

Science has also been used to develop technology that raises complex ethical questions. This is particularly true in the fields of biology and medicine (see Medical Ethics). Research involving genetic engineering, cloning, and in vitro fertilization gives scientists the unprecedented power to bring about new life, or to devise new forms of living things. At the other extreme, science can also generate technology that is deliberately designed to harm or to kill. The fruits of this research include chemical and biological warfare, and also nuclear weapons, by far the most destructive weapons that the world has ever known.
