History

Science in a broad sense existed before the modern era and in many historical civilizations.JOURNAL, Grant, Edward, History of Science: When Did Modern Science Begin?, The American Scholar, 1 January 1997, 66, 1, 105–113, 41212592, Modern science is distinct in its approach and successful in its results, so it now defines what science is in the strictest sense of the term.{{harvnb|Heilbron|2003|p=vii}}{{efn|"The historian ... requires a very broad definition of "science" â€“ one that ... will help us to understand the modern scientific enterprise. We need to be broad and inclusive, rather than narrow and exclusive ... and we should expect that the farther back we go [in time] the broader we will need to be."  â€” {{harv|Lindberg|2007|p=3}}, which further cites JOURNAL, Pingree, David, David Pingree, Hellenophilia versus the History of Science, Isis, December 1992, 4, 4, 554–63, 234257, 10.1086/356288, 1992Isis...83..554P, }} Science in its original sense was a word for a type of knowledge, rather than a specialized word for the pursuit of such knowledge. In particular, it was the type of knowledge which people can communicate to each other and share. For example, knowledge about the working of natural things was gathered long before recorded history and led to the development of complex abstract thought. This is shown by the construction of complex calendars, techniques for making poisonous plants edible, public works at national scale, such as those which harnessed the floodplain of the Yangtse with reservoirs,Sima Qian (司馬遷, d. 86 BCE) in his Records of the Grand Historian (太史公書) covering some 2500 years of Chinese history, records Sunshu Ao (孫叔敖, fl. c. 630–595 BCE – Zhou dynasty), the first known hydraulic engineer of China, cited in (Joseph Needham et.al (1971) Science and Civilisation in China 4.3 p. 271) as having built a reservoir which has lasted to this day. dams, and dikes, and buildings such as the Pyramids. However, no consistent conscious distinction was made between knowledge of such things, which are true in every community, and other types of communal knowledge, such as mythologies and legal systems. Metallurgy was known in prehistory, and the Vinča culture was the earliest known producer of bronze-like alloys. It is thought that early experimentation with heating and mixing of substances over time developed into alchemy.

Classical antiquity

{{See also|Nature (philosophy)}}In the classical world, there is no real ancient analog of a modern scientist. Instead, well-educated, usually upper-class, and almost universally male individuals performed various investigations into nature whenever they could afford the time.BOOK, Lehoux, Daryn, Shank, Michael, Numbers, Ronald, Harrison, Peter, Wrestling with Nature : From Omens to Science, 2011, University of Chicago Press, Chicago, 978-0226317830, 39, 2. Natural Knowledge in the Classical World, Before the invention or discovery of the concept of "nature" (ancient Greek phusis) by the Pre-Socratic philosophers, the same words tend to be used to describe the natural "way" in which a plant grows,See the quotation in Homer (8th century BCE) Odyssey 10.302–03 and the "way" in which, for example, one tribe worships a particular god. For this reason, it is claimed these men were the first philosophers in the strict sense, and also the first people to clearly distinguish "nature" and "convention.""Progress or Return" in An Introduction to Political Philosophy: Ten Essays by Leo Strauss (Expanded version of Political Philosophy: Six Essays by Leo Strauss, 1975.)

The Socratic method as documented by Plato's dialogues is a dialectic method of hypothesis elimination: better hypotheses are found by steadily identifying and eliminating those that lead to contradictions. This was a reaction to the Sophist emphasis on rhetoric.

Each thing has a formal cause, a final cause, and a role in a cosmic order with an unmoved mover. The Socratics also insisted that philosophy should be used to consider the practical question of the best way to live for a human being (a study Aristotle divided into ethics and political philosophy).

In contrast, the Byzantine Empire resisted the attacks from the barbarians, and preserved and improved upon the learning. John Philoponus, a Byzantine scholar in the 500s, was the first scholar ever to question Aristotle's teaching of physics and to note its flaws. John Philoponus' criticism of Aristotelian principles of physics served as an inspiration to medieval scholars as well as to Galileo Galilei who ten centuries later, during the Scientific Revolution, extensively cited Philoponus in his works while making the case as to why Aristotelian physics was flawed.Lindberg, David.

Aristotle's four causes prescribed that four "why" questions should be answered in order to explain things scientifically.Aristotle, Physics II, 3, and Metaphysics V, 2 Some ancient knowledge was lost, or in some cases kept in obscurity, during the fall of the Western Roman Empire and periodic political struggles. However, the general fields of science (or "natural philosophy" as it was called) and much of the general knowledge from the ancient world remained preserved through the works of the early Latin encyclopedists like Isidore of Seville.BOOK, The Foundations of Modern Science in the Middle Ages: Their Religious, Institutional and Intellectual Contexts, Cambridge Studies in the History of Science, Edward, Grant, Cambridge University Press, 1996, 0521567629, 7–17,weblink However, Aristotle's original texts were eventually lost in Western Europe, and only one text by Plato was widely known, the Timaeus, which was the only Platonic dialogue, and one of the few original works of classical natural philosophy, available to Latin readers in the early Middle Ages. Another original work that gained influence in this period was Ptolemy's Almagest, which contains a geocentric description of the solar system.In the Byzantine empire, many Greek classical texts were preserved.

An experiment in this period would be understood as a careful process of observing, describing, and classifying.WEB,weblink St. Albertus Magnus | German theologian, scientist, and philosopher, 2017-10-27, no,weblink October 28, 2017, mdy-all, One prominent scientist in this era was Roger Bacon. Scholasticism had a strong focus on revelation and dialectic reasoning, and gradually fell out of favour over the next centuries, as alchemy's focus on experiments that include direct observation and meticulous documentation slowly increased in importance.

Renaissance and early modern science

Brahe's observations were the basis for Kepler's lawsKepler's lawsAlhazen disproved Ptolemy's theory of vision,{{harvnb|Smith|2001}}{{rp|Book I, [6.54]. p. 372}} but did not make any corresponding changes to Aristotle's metaphysics. The scientific revolution ran concurrently to a process where elements of Aristotle's metaphysics such as ethics, teleology and formal causality slowly fell out of favour. Scholars slowly came to realize that the universe itself might well be devoid of both purpose and ethical imperatives. The development from a physics infused with goals, ethics, and spirit, toward a physics where these elements do not play an integral role, took centuries. This development was enhanced by the Condemnations of 1277, where Aristotle's books were banned by the Catholic church. This allowed the theoretical possibility of vacuum and motion in a vacuum. A direct result was the emergence of the science of dynamics.New developments in optics played a role in the inception of the Renaissance, both by challenging long-held metaphysical ideas on perception, as well as by contributing to the improvement and development of technology such as the camera obscura and the telescope. Before what we now know as the Renaissance started, Roger Bacon, Vitello, and John Peckham each built up a scholastic ontology upon a causal chain beginning with sensation, perception, and finally apperception of the individual and universal forms of Aristotle.JOURNAL, 3657358, Alhacen's Theory of Visual Perception: A Critical Edition, with English Translation and Commentary, of the First Three Books of Alhacen's "De aspectibus", the Medieval Latin Version of Ibn al-Haytham's "Kitāb al-Manāẓir": Volume One, Transactions of the American Philosophical Society, 91, 4, i–337, Smith, A.

  • The full title translation is from p. 60 of James R. Voelkel (2001) Johannes Kepler and the New Astronomy Oxford University Press. Kepler was driven to this experiment after observing the partial solar eclipse at Graz, July 10, 1600. He used Tycho Brahe's method of observation, which was to project the image of the Sun on a piece of paper through a pinhole aperture, instead of looking directly at the Sun. He disagreed with Brahe's conclusion that total eclipses of the Sun were impossible, because there were historical accounts of total eclipses. Instead he deduced that the size of the aperture controls the sharpness of the projected image (the larger the aperture, the more accurate the image â€“ this fact is now fundamental for optical system design). Voelkel, p. 61, notes that Kepler's experiments produced the first correct account of vision and the eye, because he realized he could not accurately write about astronomical observation by ignoring the eye.}} Kepler is best known, however, for improving Copernicus' heliocentric model through the discovery of Kepler's laws of planetary motion. Kepler did not reject Aristotelian metaphysics, and described his work as a search for the Harmony of the Spheres.

However, he became persecuted after Pope Urban VIII blessed Galileo to write about the Copernican system. Galileo had used arguments from the Pope and put them in the voice of the simpleton in the work "Dialogue Concerning the Two Chief World Systems", which greatly offended Urban VIII.WEB,weblink Pope Urban VIII, van Helden, Al, 1995, The Galileo Project, November 3, 2016, no,weblink" title="web.archive.org/web/20161111033150weblink">weblink November 11, 2016, mdy-all, In Northern Europe, the new technology of the printing press was widely used to publish many arguments, including some that disagreed widely with contemporary ideas of nature. René Descartes and Francis Bacon published philosophical arguments in favor of a new type of non-Aristotelian science. Descartes emphasized individual thought and argued that mathematics rather than geometry should be used in order to study nature. Bacon emphasized the importance of experiment over contemplation. Bacon further questioned the Aristotelian concepts of formal cause and final cause, and promoted the idea that science should study the laws of "simple" natures, such as heat, rather than assuming that there is any specific nature, or "formal cause", of each complex type of thing. This new science began to see itself as describing "laws of nature". This updated approach to studies in nature was seen as mechanistic. Bacon also argued that science should aim for the first time at practical inventions for the improvement of all human life.

Age of Enlightenment

File:GodfreyKneller-IsaacNewton-1689.jpg|thumb|upright=1.0|left|Isaac Newton, shown here in a 1689 portrait, made seminal contributions to classical mechanics, gravity, and optics. Newton shares credit with Gottfried LeibnizGottfried LeibnizAs a precursor to the Age of Enlightenment, Isaac Newton and Gottfried Wilhelm Leibniz succeeded in developing a new physics, now referred to as classical mechanics, which could be confirmed by experiment and explained using mathematics. Leibniz also incorporated terms from Aristotelian physics, but now being used in a new non-teleological way, for example, "energy" and "potential" (modern versions of Aristotelian "energeia and potentia"). This implied a shift in the view of objects: Where Aristotle had noted that objects have certain innate goals that can be actualized, objects were now regarded as devoid of innate goals. In the style of Francis Bacon, Leibniz assumed that different types of things all work according to the same general laws of nature, with no special formal or final causes for each type of thing. It is during this period that the word "science" gradually became more commonly used to refer to a type of pursuit of a type of knowledge, especially knowledge of nature â€“ coming close in meaning to the old term "natural philosophy."During this time, the declared purpose and value of science became producing wealth and inventions that would improve human lives, in the materialistic sense of having more food, clothing, and other things. In Bacon's words, "the real and legitimate goal of sciences is the endowment of human life with new inventions and riches", and he discouraged scientists from pursuing intangible philosophical or spiritual ideas, which he believed contributed little to human happiness beyond "the fume of subtle, sublime, or pleasing speculation".BOOK,weblink The Social and Economic Roots of the Scientific Revolution: Texts by Boris Hessen and Henryk Grossmann, Freudenthal, Gideon, McLaughlin, Peter, 2009-05-20, Springer Science & Business Media, 9781402096044, Science during the Enlightenment was dominated by scientific societies and academies, which had largely replaced universities as centres of scientific research and development. Societies and academies were also the backbone of the maturation of the scientific profession. Another important development was the popularization of science among an increasingly literate population. Philosophes introduced the public to many scientific theories, most notably through the Encyclopédie and the popularization of Newtonianism by Voltaire as well as by Émilie du Châtelet, the French translator of Newton's Principia.Some historians have marked the 18th century as a drab period in the history of science;see Hall (1954), iii; Mason (1956), 223. however, the century saw significant advancements in the practice of medicine, mathematics, and physics; the development of biological taxonomy; a new understanding of magnetism and electricity; and the maturation of chemistry as a discipline, which established the foundations of modern chemistry.Enlightenment philosophers chose a short history of scientific predecessors â€“ Galileo, Boyle, and Newton principally â€“ as the guides and guarantors of their applications of the singular concept of nature and natural law to every physical and social field of the day. In this respect, the lessons of history and the social structures built upon it could be discarded.Cassels, Alan. Ideology and International Relations in the Modern World. p. 2.

19th century

When Charles Darwin published On the Origin of Species he established evolution as the prevailing explanation of biological complexity. His theory of natural selection provided a natural explanation of how species originated, but this only gained wide acceptance a century later.The laws of conservation of energy, conservation of momentum and conservation of mass suggested a highly stable universe where there could be little loss of resources. With the advent of the steam engine and the industrial revolution, there was, however, an increased understanding that all forms of energy as defined by Newton were not equally useful; they did not have the same energy quality. This realization led to the development of the laws of thermodynamics, in which the cumulative energy quality of the universe is seen as constantly declining: the entropy of the universe increases over time.The electromagnetic theory was also established in the 19th century, and raised new questions which could not easily be answered using Newton's framework. The phenomena that would allow the deconstruction of the atom were discovered in the last decade of the 19th century: the discovery of X-rays inspired the discovery of radioactivity. In the next year came the discovery of the first subatomic particle, the electron.

20th century

At the same time, the structure of the atom and its nucleus was discovered, leading to the release of "atomic energy" (nuclear power). In addition, the extensive use of technological innovation stimulated by the wars of this century led to revolutions in transportation (automobiles and aircraft), the development of ICBMs, a space race, and a nuclear arms race.The molecular structure of DNA was discovered in 1953. The discovery of the cosmic microwave background radiation in 1964 led to a rejection of the Steady State theory of the universe in favour of the Big Bang theory of Georges Lemaître.The development of spaceflight in the second half of the century allowed the first astronomical measurements done on or near other objects in space, including manned landings on the Moon. Space telescopes lead to numerous discoveries in astronomy and cosmology.Widespread use of integrated circuits in the last quarter of the 20th century combined with communications satellites led to a revolution in information technology and the rise of the global internet and mobile computing, including smartphones. The need for mass systematization of long, intertwined causal chains and large amounts of data led to the rise of the fields of systems theory and computer-assisted scientific modelling, which are partly based on the Aristotelian paradigm.JOURNAL, 10.2307/255139, 255139, The History and Status of General Systems Theory, The Academy of Management Journal, 15, 4, 407–26, von Bertalanffy, Ludwig, 1972, Harmful environmental issues such as ozone depletion, acidification, eutrophication and climate change came to the public's attention in the same period, and caused the onset of environmental science and environmental technology.

Branches of science

Modern science is commonly divided into three major branches that consist of the natural sciences, social sciences, and formal sciences. Each of these branches comprise various specialized yet overlapping scientific disciplines that often possess their own nomenclature and expertise.WEB,weblink Scientific Method: Relationships Among Scientific Paradigms, March 7, 2007, Seed Magazine, November 4, 2016, no,weblink" title="web.archive.org/web/20161101001155weblink">weblink November 1, 2016, mdy-all, Both natural and social sciences are empirical sciencesBOOK, Philosophy of Science: From Problem to Theory, Bunge, Mario Augusto, 1998, Transaction Publishers, 978-0-7658-0413-6, 24, as their knowledge are based on empirical observations and are capable of being tested for its validity by other researchers working under the same conditions.{{sfn|Popper|2002|p=20}}There are also closely related disciplines that use science, such as engineering and medicine.

Natural science

Natural science is concerned with the description, prediction, and understanding of natural phenomena based on empirical evidence from observation and experimentation. It can be divided into two main branches: life science (or biological science) and physical science. Physical science is subdivided into branches, including physics, chemistry, astronomy and earth science. These two branches may be further divided into more specialized disciplines. Modern natural science is the successor to the natural philosophy that began in Ancient Greece. Galileo, Descartes, Bacon, and Newton debated the benefits of using approaches which were more mathematical and more experimental in a methodical way. Still, philosophical perspectives, conjectures, and presuppositions, often overlooked, remain necessary in natural science.Hugh G. Gauch Jr, Scientific Method in Practice (Cambridge: Cambridge University Press, 2003), pp. 71–73 {{webarchive|url=https://web.archive.org/web/20150906160524weblink |date=2015-09-06 }} Systematic data collection, including discovery science, succeeded natural history, which emerged in the 16th century by describing and classifying plants, animals, minerals, and so on.{{sfn|Oglivie|2008|pp=1–2}} Today, "natural history" suggests observational descriptions aimed at popular audiences.WEB, Natural History,weblink Princeton University WordNet, October 21, 2012, no,weblink" title="web.archive.org/web/20120303173506weblink">weblink March 3, 2012,

Social science

File:Supply-demand-right-shift-demand.svg|thumb|right|In economics, the supply and demandsupply and demandSocial science is concerned with society and the relationships among individuals within a society. It has many branches that include, but are not limited to, anthropology, archaeology, communication studies, economics, history, human geography, jurisprudence, linguistics, political science, psychology, public health, and sociology. Social scientists may adopt various philosophical theories to study individuals and society. For example, positivist social scientists use methods resembling those of the natural sciences as tools for understanding society, and so define science in its stricter modern sense. Interpretivist social scientists, by contrast, may use social critique or symbolic interpretation rather than constructing empirically falsifiable theories, and thus treat science in its broader sense. In modern academic practice, researchers are often eclectic, using multiple methodologies (for instance, by combining both quantitative and qualitative research). The term "social research" has also acquired a degree of autonomy as practitioners from various disciplines share in its aims and methods.

Formal science

File:Shadow Hand Bulb large.jpg|thumb|right|A humanoid robotic hand (see Shadow HandShadow HandFormal science is involved in the study of formal systems. It includes mathematics,BOOK, Tomalin, Marcus, 2006, Linguistics and the Formal Sciences, 10.2277/0521854814, JOURNAL, The Formal Sciences: Their Scope, Their Foundations, and Their Unity, Synthese, 133, 5–11, 10.1023/a:1020887832028, 2002, Löwe, Benedikt, systems theory, robotics, and theoretical computer science. The formal sciences share similarities with the other two branches by relying on objective, careful, and systematic study of an area of knowledge. They are, however, different from the empirical sciences as they rely exclusively on deductive reasoning, without the need for empirical evidence, to verify their abstract concepts.{{Citation |first=Thompson | last = Bill |title=The Nature of Statistical Evidence |chapter=2.4 Formal Science and Applied Mathematics |publisher=Springer |series=Lecture Notes in Statistics |volume=189 |edition=1st |year=2007 |page=15}}{{sfn|Popper|2002|pp=10–11}} The formal sciences are therefore a priori disciplines and because of this, there is disagreement on whether they actually constitute a science. Nevertheless, the formal sciences play an important role in the empirical sciences. Calculus, for example, was initially invented to understand motion in physics.BOOK, Mujumdar, Anshu Gupta, Singh, Tejinder, 2016, Cognitive science and the connection between physics and mathematics, Trick or Truth?: The Mysterious Connection Between Physics and Mathematics, Anthony Aguirre, Brendan Foster, 1st, The Frontiers Collection, 201–218, Switzerland, SpringerNature, 978-3-319-27494-2, Natural and social sciences that rely heavily on mathematical applications include mathematical physics, mathematical chemistry, mathematical biology, mathematical finance, and mathematical economics.

Scientific research

{{See also|Research}}Scientific research can be labeled as either basic or applied research. Basic research is the search for knowledge and applied research is the search for solutions to practical problems using this knowledge. Although some scientific research is applied research into specific problems, a great deal of our understanding comes from the curiosity-driven undertaking of basic research. This leads to options for technological advance that were not planned or sometimes even imaginable. This point was made by Michael Faraday when allegedly in response to the question "what is the use of basic research?" he responded: "Sir, what is the use of a new-born child?".WEB,weblinkweblink" title="web.archive.org/web/20120119113522weblink">weblink January 19, 2012, To Live at All Is Miracle Enough, Richard Dawkins, RichardDawkins.net, May 10, 2006, February 5, 2012, For example, research into the effects of red light on the human eye's rod cells did not seem to have any practical purpose; eventually, the discovery that our night vision is not troubled by red light would lead search and rescue teams (among others) to adopt red light in the cockpits of jets and helicopters.{{rp|106–10}} Finally, even basic research can take unexpected turns, and there is some sense in which the scientific method is built to harness luck.

Experimentation is especially important in science to help establish causal relationships (to avoid the correlation fallacy).When a hypothesis proves unsatisfactory, it is either modified or discarded.{{sfn|Nola|Irzik|2005|p=208}} If the hypothesis survived testing, it may become adopted into the framework of a scientific theory, a logically reasoned, self-consistent model or framework for describing the behavior of certain natural phenomena. A theory typically describes the behavior of much broader sets of phenomena than a hypothesis; commonly, a large number of hypotheses can be logically bound together by a single theory. Thus a theory is a hypothesis explaining various other hypotheses. In that vein, theories are formulated according to most of the same scientific principles as hypotheses. In addition to testing hypotheses, scientists may also generate a model, an attempt to describe or depict the phenomenon in terms of a logical, physical or mathematical representation and to generate new hypotheses that can be tested, based on observable phenomena.{{sfn|Nola|Irzik|2005|pp=199–201}}While performing experiments to test hypotheses, scientists may have a preference for one outcome over another, and so it is important to ensure that science as a whole can eliminate this bias.WEB, van Gelder, Tim, 1999,weblink PDF, "Heads I win, tails you lose": A Foray Into the Psychology of Philosophy, University of Melbourne, March 28, 2008,weblink" title="web.archive.org/web/20080409054240weblink">weblink April 9, 2008, WEB, Pease, Craig, September 6, 2006,weblink" title="web.archive.org/web/20100619154617weblink">weblink June 19, 2010, Chapter 23.

(File:Integral as region under curve.svg|thumb|right|Calculus, the mathematics of continuous change, underpins many of the sciences.)Mathematics is essential in the formation of hypotheses, theories, and laws{{sfn|Popper|2002|pp=79–82}} in the natural and social sciences. For example, it is used in quantitative scientific modeling, which can generate new hypotheses and predictions to be tested. It is also used extensively in observing and collecting measurements. Statistics, a branch of mathematics, is used to summarize and analyze data, which allow scientists to assess the reliability and variability of their experimental results.Computational science applies computing power to simulate real-world situations, enabling a better understanding of scientific problems than formal mathematics alone can achieve.

John Ziman points out that intersubjective verifiability is fundamental to the creation of all scientific knowledge.Ziman cites {{harvnb|Polanyi|1958}} chapter 12, as referenced in {{harvnb|Ziman|1978}}{{rp|44}} Ziman shows how scientists can identify patterns to each other across centuries; he refers to this ability as "perceptual consensibility."{{harvnb|Ziman|1978}}{{rp|46}} He then makes consensibility, leading to consensus, the touchstone of reliable knowledge.{{rp|104}}

Philosophy of science

{{See also|Philosophy of science}}File:JohnLocke.png|thumb|English philosopher and physician John LockeJohn LockeScientists usually take for granted a set of basic assumptions that are needed to justify the scientific method: (1) that there is an objective reality shared by all rational observers; (2) that this objective reality is governed by natural laws; (3) that these laws can be discovered by means of systematic observation and experimentation. Philosophy of science seeks a deep understanding of what these underlying assumptions mean and whether they are valid.The belief that scientific theories should and do represent metaphysical reality is known as realism. It can be contrasted with anti-realism, the view that the success of science does not depend on it being accurate about unobservable entities such as electrons. One form of anti-realism is idealism, the belief that the mind or consciousness is the most basic essence, and that each mind generates its own reality.{{efn|This realization is the topic of intersubjective verifiability, as recounted, for example, by Max Born (1949, 1965) Natural Philosophy of Cause and Chance, who points out that all knowledge, including natural or social science, is also subjective. p. 162: "Thus it dawned upon me that fundamentally everything is subjective, everything without exception. That was a shock."}} In an idealistic world view, what is true for one mind need not be true for other minds.There are different schools of thought in philosophy of science. The most popular position is empiricism,{{efn|name=Galileo1638|In his investigation of the law of falling bodies, Galileo (1638) serves as example for scientific investigation: Two New Sciences "A piece of wooden moulding or scantling, about 12 cubits long, half a cubit wide, and three finger-breadths thick, was taken; on its edge was cut a channel a little more than one finger in breadth; having made this groove very straight, smooth, and polished, and having lined it with parchment, also as smooth and polished as possible, we rolled along it a hard, smooth, and very round bronze ball. Having placed this board in a sloping position, by lifting one end some one or two cubits above the other, we rolled the ball, as I was just saying, along the channel, noting, in a manner presently to be described, the time required to make the descent. We ... now rolled the ball only one-quarter the length of the channel; and having measured the time of its descent, we found it precisely one-half of the former. Next we tried other distances, comparing the time for the whole length with that for the half, or with that for two-thirds, or three-fourths, or indeed for any fraction; in such experiments, repeated many, many, times." Galileo solved the problem of time measurement by weighing a jet of water collected during the descent of the bronze ball, as stated in his Two New Sciences.}} which holds that knowledge is created by a process involving observation and that scientific theories are the result of generalizations from such observations."... [T]he logical empiricists thought that the great aim of science was to discover and establish generalizations." â€”{{harvnb| Godfrey-Smith|2003|p=41}} Empiricism generally encompasses inductivism, a position that tries to explain the way general theories can be justified by the finite number of observations humans can make and hence the finite amount of empirical evidence available to confirm scientific theories. This is necessary because the number of predictions those theories make is infinite, which means that they cannot be known from the finite amount of evidence using deductive logic only. Many versions of empiricism exist, with the predominant ones being Bayesianism{{Sfn|Godfrey-Smith|2003|p=203}} and the hypothetico-deductive method.{{harvnb| Godfrey-Smith|2003}}{{rp|236}}File:Karl Popper2.jpg|left|thumb|The Austrian-British philosopher of science Karl Popper (1902–1994) in 1990. He is best known for his work on empirical falsification.]]Empiricism has stood in contrast to rationalism, the position originally associated with Descartes, which holds that knowledge is created by the human intellect, not by observation.{{rp|20}} Critical rationalism is a contrasting 20th-century approach to science, first defined by Austrian-British philosopher Karl Popper. Popper rejected the way that empiricism describes the connection between theory and observation. He claimed that theories are not generated by observation, but that observation is made in the light of theories and that the only way a theory can be affected by observation is when it comes in conflict with it.{{rp|63–67}} Popper proposed replacing verifiability with falsifiability as the landmark of scientific theories and replacing induction with falsification as the empirical method.{{rp|68}} Popper further claimed that there is actually only one universal method, not specific to science: the negative method of criticism, trial and error.Popper called this Conjecture and Refutation. {{harvnb| Godfrey-Smith|2003|pp=117–18}} It covers all products of the human mind, including science, mathematics, philosophy, and art.BOOK, Objective Knowledge, Popper, Karl, 1972, Another approach, instrumentalism, colloquially termed "shut up and multiply,"WEB,weblink Shut up and multiply, September 13, 2015, LessWrong Wiki, November 4, 2016, no,weblink October 19, 2016, mdy-all, emphasizes the utility of theories as instruments for explaining and predicting phenomena.BOOK, The Rationality of Science, Newton-Smith, W.H., London, Routledge, 1994, 30, 978-0-7100-0913-5, It views scientific theories as black boxes with only their input (initial conditions) and output (predictions) being relevant. Consequences, theoretical entities, and logical structure are claimed to be something that should simply be ignored and that scientists shouldn't make a fuss about (see interpretations of quantum mechanics). Close to instrumentalism is constructive empiricism, according to which the main criterion for the success of a scientific theory is whether what it says about observable entities is true.Thomas Kuhn argued that the process of observation and evaluation takes place within a paradigm, a logically consistent "portrait" of the world that is consistent with observations made from its framing. He characterized normal science as the process of observation and "puzzle solving" which takes place within a paradigm, whereas revolutionary science occurs when one paradigm overtakes another in a paradigm shift.JOURNAL,weblink Thomas Kuhn, 2015-10-26, Bird, Alexander, 2013, Stanford Encyclopedia of Philosophy, Zalta, Edward N., Each paradigm has its own distinct questions, aims, and interpretations. The choice between paradigms involves setting two or more "portraits" against the world and deciding which likeness is most promising. A paradigm shift occurs when a significant number of observational anomalies arise in the old paradigm and a new paradigm makes sense of them. That is, the choice of a new paradigm is based on observations, even though those observations are made against the background of the old paradigm. For Kuhn, acceptance or rejection of a paradigm is a social process as much as a logical process. Kuhn's position, however, is not one of relativism.T.S. Kuhn, The Structure of Scientific Revolutions, 2nd. ed., Chicago: Univ. of Chicago Pr., 1970, p. 206. {{ISBN|0-226-45804-0}}Finally, another approach often cited in debates of scientific skepticism against controversial movements like "creation science" is methodological naturalism. Its main point is that a difference between natural and supernatural explanations should be made and that science should be restricted methodologically to natural explanations.{{efn|{{harvnb| Godfrey-Smith|2003|p=151}} credits Willard Van Orman Quine (1969) "Epistemology Naturalized" Ontological Relativity and Other Essays New York: Columbia University Press, as well as John Dewey, with the basic ideas of naturalism â€“ Naturalized Epistemology, but Godfrey-Smith diverges from Quine's position: according to Godfrey-Smith, "A naturalist can think that science can contribute to answers to philosophical questions, without thinking that philosophical questions can be replaced by science questions.".}} That the restriction is merely methodological (rather than ontological) means that science should not consider supernatural explanations itself, but should not claim them to be wrong either. Instead, supernatural explanations should be left a matter of personal belief outside the scope of science. Methodological naturalism maintains that proper science requires strict adherence to empirical study and independent verification as a process for properly developing and evaluating explanations for observable phenomena.JOURNAL, The Review of Metaphysics, Casebeer, William D. Natural Ethical Facts: Evolution, Connectionism, and Moral Cognition, Brugger, E. Christian, 58, 2, 2004, harv, The absence of these standards, arguments from authority, biased observational studies and other common fallacies are frequently cited by supporters of methodological naturalism as characteristic of the non-science they criticize.

Certainty and science

A scientific theory is empirical{{efn|name=Galileo1638}}WEB,weblink The Structure of Scientific Theories, Winther, Rasmus Grønfeldt, 2015, Stanford Encyclopedia of Philosophy, November 4, 2016, and is always open to falsification if new evidence is presented.

He wrote that scientific knowledge "consists in the search for truth," but it "is not the search for certainty ... All human knowledge is fallible and therefore uncertain."{{sfn|Popper|1996}}{{rp|4}}New scientific knowledge rarely results in vast changes in our understanding. According to psychologist Keith Stanovich, it may be the media's overuse of words like "breakthrough" that leads the public to imagine that science is constantly proving everything it thought was true to be false.{{rp|119–38}} While there are such famous cases as the theory of relativity that required a complete reconceptualization, these are extreme exceptions. Knowledge in science is gained by a gradual synthesis of information from different experiments by various researchers across different branches of science; it is more like a climb than a leap.{{rp|123}} Theories vary in the extent to which they have been tested and verified, as well as their acceptance in the scientific community.{{efn|BOOK, Fleck, Ludwik, Ludwik Fleck, Thaddeus J., Trenn, Robert K, Merton, Genesis and Development of a Scientific Fact, 1979, University of Chicago Press, Chicago, 978-0-226-25325-1, Claims that before a specific fact "existed", it had to be created as part of a social agreement within a community. Steven Shapin (1980) "A view of scientific thought" Science ccvii (Mar 7, 1980) 1065–66 states "[To Fleck,] facts are invented, not discovered.

This means a scientist would not ask merely "What is the cause of ...", but rather "What are the most significant causes of ...". This is especially the case in the more macroscopic fields of science (e.g. psychology, physical cosmology).{{harvnb|Stanovich|2007}}{{rp|141–47}} Research often analyzes few factors at once, but these are always added to the long list of factors that are most important to consider.{{rp|141–47}} For example, knowing the details of only a person's genetics, or their history and upbringing, or the current situation may not explain a behavior, but a deep understanding of all these variables combined can be very predictive.

Fringe science, pseudoscience, and junk science

An area of study or speculation that masquerades as science in an attempt to claim a legitimacy that it would not otherwise be able to achieve is sometimes referred to as pseudoscience, fringe science, or junk science.{{efn|"Pseudoscientific â€“ pretending to be scientific, falsely represented as being scientific", from the Oxford American Dictionary, published by the Oxford English Dictionary; Hansson, Sven Ove (1996)."Defining Pseudoscience", Philosophia Naturalis, 33: 169–76, as cited in "Science and Pseudo-science" (2008) in Stanford Encyclopedia of Philosophy. The Stanford article states: "Many writers on pseudoscience have emphasized that pseudoscience is non-science posing as science. The foremost modern classic on the subject (Gardner 1957) bears the title Fads and Fallacies in the Name of Science. According to Brian Baigrie (1988, 438), "[w]hat is objectionable about these beliefs is that they masquerade as genuinely scientific ones." These and many other authors assume that to be pseudoscientific, an activity or a teaching has to satisfy the following two criteria (Hansson 1996): (1) it is not scientific, and (2) its major proponents try to create the impression that it is scientific".

Most scientific societies are non-profit organizations, and many are professional associations. Their activities typically include holding regular conferences for the presentation and discussion of new research results and publishing or sponsoring academic journals in their discipline. Some also act as professional bodies, regulating the activities of their members in the public interest or the collective interest of the membership. Scholars in the sociology of science{{who|date=September 2014}} argue that learned societies are of key importance and their formation assists in the emergence and development of new disciplines or professions.The professionalization of science, begun in the 19th century, was partly enabled by the creation of distinguished academy of sciences in a number of countries such as the Italian in 1603,WEB, 2006,weblink Accademia Nazionale dei Lincei, Italian, September 11, 2007, no,weblink" title="web.archive.org/web/20100228005402weblink">weblink February 28, 2010, mdy-all, the British Royal Society in 1660, the French in 1666,WEB, G.G., Meynell,weblink The French Academy of Sciences, 1666–91: A reassessment of the French Académie royale des sciences under Colbert (1666–83) and Louvois (1683–91), October 13, 2011, yes,weblink" title="web.archive.org/web/20120118174108weblink">weblink January 18, 2012, mdy-all, the American National Academy of Sciences in 1863, the German Kaiser Wilhelm Institute in 1911, and the Chinese Academy of Sciences in 1928.

Science and the public

Science policy

(File:UN-Science-Policy-Business Forum on Environment.jpg|thumb|right|The United Nations Global Science-Policy-Business Forum on the Environment in Nairobi, Kenya (2017).)Science policy is an area of public policy concerned with the policies that affect the conduct of the scientific enterprise, including research funding, often in pursuance of other national policy goals such as technological innovation to promote commercial product development, weapons development, health care and environmental monitoring. Science policy also refers to the act of applying scientific knowledge and consensus to the development of public policies. Science policy thus deals with the entire domain of issues that involve the natural sciences. In accordance with public policy being concerned about the well-being of its citizens, science policy's goal is to consider how science and technology can best serve the public.State policy has influenced the funding of public works and science for thousands of years, particularly within civilizations with highly organized governments such as imperial China and the Roman Empire. Prominent historical examples include the Great Wall of China, completed over the course of two millennia through the state support of several dynasties, and the Grand Canal of the Yangtze River, an immense feat of hydraulic engineering begun by Sunshu Ao (孫叔敖 7th c. BCE), Ximen Bao (西門豹 5th c.BCE), and Shi Chi (4th c. BCE). This construction dates from the 6th century BCE under the Sui Dynasty and is still in use today. In China, such state-supported infrastructure and scientific research projects date at least from the time of the Mohists, who inspired the study of logic during the period of the Hundred Schools of Thought and the study of defensive fortifications like the Great Wall of China during the Warring States period.Public policy can directly affect the funding of capital equipment and intellectual infrastructure for industrial research by providing tax incentives to those organizations that fund research. Vannevar Bush, director of the Office of Scientific Research and Development for the United States government, the forerunner of the National Science Foundation, wrote in July 1945 that "Science is a proper concern of government."WEB,weblink Science the Endless Frontier, Bush, Vannevar, July 1945, National Science Foundation, November 4, 2016, no,weblink November 7, 2016, mdy-all,

Funding of science

File:CSIRO Main Entomology Building - Central Block.jpg|thumb|right|The Commonwealth Scientific and Industrial Research Organisation (CSIRO) Main Entomology Building in Australia]]Scientific research is often funded through a competitive process in which potential research projects are evaluated and only the most promising receive funding. Such processes, which are run by government, corporations, or foundations, allocate scarce funds. Total research funding in most developed countries is between 1.5% and 3% of GDP.WEB,weblink PDF, Main Science and Technology Indicators â€“ 2008-1, OECD, yes,weblink October 19, 2010, In the OECD, around two-thirds of research and development in scientific and technical fields is carried out by industry, and 20% and 10% respectively by universities and government. The government funding proportion in certain industries is higher, and it dominates research in social science and humanities. Similarly, with some exceptions (e.g. biotechnology) government provides the bulk of the funds for basic scientific research. Many governments have dedicated agencies to support scientific research. Prominent scientific organizations include the National Science Foundation in the United States, the National Scientific and Technical Research Council in Argentina, Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia, in France, the Max Planck Society and in Germany, and CSIC in Spain. In commercial research and development, all but the most research-oriented corporations focus more heavily on near-term commercialisation possibilities rather than "blue-sky" ideas or technologies (such as nuclear fusion).

Public awareness of science

{{Further|Science outreach|Science communication}}File:Dinosaur exhibit - Houston Museum of Natural Science - DSC01881.JPG|thumb|250px|right|Dinosaur exhibit in the Houston Museum of Natural ScienceHouston Museum of Natural ScienceThe public awareness of science relates to the attitudes, behaviors, opinions, and activities that make up the relations between science and the general public. it integrates various themes and activities such as science communication, science museums, science festivals, science fairs, citizen science, and science in popular culture. Social scientists have devised various metrics to measure the public understanding of science such as factual knowledge, self-reported knowledge, and structural knowledge.JOURNAL, Ladwig, Peter, Perceived familiarity or factual knowledge? Comparing operationalizations of scientific understanding, Science and Public Policy, 39, 6, 761–74, 10.1093/scipol/scs048, 2012, JOURNAL, Eveland, William, How Web Site Organization Influences Free Recall, Factual Knowledge, and Knowledge Structure Density, Human Communications Research, 30, 2, 208–33, 10.1111/j.1468-2958.2004.tb00731.x, 2004,

Science journalism

The mass media face a number of pressures that can prevent them from accurately depicting competing scientific claims in terms of their credibility within the scientific community as a whole. Determining how much weight to give different sides in a scientific debate may require considerable expertise regarding the matter.WEB, Dickson, David, October 11, 2004,weblinkweblink" title="web.archive.org/web/20100621053624weblink">weblink June 21, 2010, Science journalism must keep a critical edge, Science and Development Network, Few journalists have real scientific knowledge, and even beat reporters who know a great deal about certain scientific issues may be ignorant about other scientific issues that they are suddenly asked to cover.JOURNAL, Mooney, Chris, Nov–Dec 2004,weblink Blinded By Science, How 'Balanced' Coverage Lets the Scientific Fringe Hijack Reality, 43, Columbia Journalism Review, February 20, 2008, 4, harv, no,weblink" title="web.archive.org/web/20100117181240weblink">weblink January 17, 2010, mdy-all, JOURNAL, McIlwaine, S., Nguyen, D.A., Are Journalism Students Equipped to Write About Science?, Australian Studies in Journalism, 2005, 14, 41–60,weblink February 20, 2008, harv, no,weblink" title="web.archive.org/web/20080801163322weblink">weblink August 1, 2008, mdy-all,

Politicization of science

File:Cook et al. (2016) Studies consensus.jpg|thumb|300px|Results of seven papers from 2004–2015 assessing the overwhelming scientific consensus on man-made global warming (see Surveys of scientists' views on climate change), in contrast to the political controversy over this issue, particularly in the United States.]]Politicization of science occurs when government, business, or advocacy groups use legal or economic pressure to influence the findings of scientific research or the way it is disseminated, reported, or interpreted. Many factors can act as facets of the politicization of science such as populist anti-intellectualism, perceived threats to religious beliefs, postmodernist subjectivism, and fear for business interests.JOURNAL, Goldberg, Jeanne, The Politicization of Scientific Issues: Looking through Galileo's Lens or through the Imaginary Looking Glass, Skeptical Inquirer, 2017, 41, 5, 34–39,weblink 16 August 2018, Politicization of science is usually accomplished when scientific information is presented in a way that emphasizes the uncertainty associated with the scientific evidence.JOURNAL, Bolsen, Toby, Druckman, James N., Counteracting the Politicization of Science, Journal of Communication, 2015, 65, 746, Tactics such as shifting conversation, failing to acknowledge facts, and capitalizing on doubt of scientific consensus have been used to gain more attention for views that have been undermined by scientific evidence.JOURNAL, Freudenberg, William F., Scientific Certainty Argumentation Methods (SCAMs): Science and the Politics of Doubt, Sociological Inquiry, 78, 2–38, 10.1111/j.1475-682X.2008.00219, 2018-11-09, Examples of issues that have involved the politicization of science include the global warming controversy, health effects of pesticides, and health effects of tobacco.JOURNAL, van der Linden, Sander, Leiserowitz, Anthony, Rosenthal, Seth, Maibach, Edward, Inoculating the Public against Misinformation about Climate Change, Global Challenges, 1, 2, 1, 10.1002/gch2.201600008, 2017,
