Empirical in the context of Scientific method

Political philosophy studies the theoretical and conceptual foundations of politics. It examines the nature, scope, and legitimacy of political institutions, such as states. The field investigates different forms of government, ranging from democracy to authoritarianism, and the values guiding political action, like justice, equality, and liberty. As a normative field, political philosophy focuses on desirable norms and values, in contrast to political science, which emphasizes empirical description.

Political ideologies are systems of ideas and principles that outline how society should work. Anarchism rejects the coercive power of centralized governments. It proposes a stateless society to promote liberty and equality. Conservatism seeks to preserve traditional institutions and practices. It is skeptical of the human ability to radically reform society, arguing that drastic changes can destroy the wisdom of past generations. Liberals advocate for individual rights and liberties, the rule of law, private property, and tolerance. They believe that governments should protect these values to enable individuals to pursue personal goals without external interference. Socialism emphasizes collective ownership and equal distribution of basic goods. It seeks to overcome sources of inequality, including private ownership of the means of production, class systems, and hereditary privileges. Other strands of political philosophy include environmentalism, realism, idealism, consequentialism, perfectionism, nationalism, individualism, and communitarianism.

Babylonian astronomy was the study or recording of celestial objects during the early history of Mesopotamia. The numeral system used, sexagesimal, was based on 60, as opposed to ten in the modern decimal system. This system simplified the calculating and recording of unusually great and small numbers.

During the 8th and 7th centuries BC, Babylonian astronomers developed a new empirical approach to astronomy. They began studying and recording their belief system and philosophies dealing with an ideal nature of the universe and began employing an internal logic within their predictive planetary systems. This was an important contribution to astronomy and the philosophy of science, and some modern scholars have thus referred to this approach as a scientific revolution. This approach to astronomy was adopted and further developed in Greek and Hellenistic astrology. Classical Greek and Latin sources frequently use the term Chaldeans for the philosophers, who were considered as priest-scribes specializing in astronomical and other forms of divination. Babylonian astronomy paved the way for modern astrology and is responsible for its spread across the Graeco-Roman empire during the 2nd-century Hellenistic Period. The Babylonians used the sexagesimal system to trace the planets' transits, by dividing the 360 degree sky into 30 degrees, they assigned 12 zodiacal signs to the stars along the ecliptic.

Formal science is a branch of science studying disciplines concerned with abstract structures described by formal systems, such as logic, mathematics, statistics, theoretical computer science, artificial intelligence, information theory, game theory, systems theory, decision theory and theoretical linguistics. Whereas the natural sciences and social sciences seek to characterize physical systems and social systems, respectively, using theoretical and empirical methods, the formal sciences use language tools concerned with characterizing abstract structures described by formal systems and the deductions that can be made from them. The formal sciences aid the natural and social sciences by providing information about the structures used to describe the physical world, and what inferences may be made about them.

Traditional knowledge (TK), indigenous knowledge (IK), folk knowledge, and local knowledge generally refers to knowledge systems embedded in the cultural traditions of regional, indigenous, or local communities.

Traditional knowledge includes types of knowledge about traditional technologies of areas such as subsistence (e.g. tools and techniques for hunting or agriculture), midwifery, ethnobotany and ecological knowledge, traditional medicine, celestial navigation, craft skills, ethnoastronomy, climate, and others. These systems of knowledge are generally based on accumulations of empirical observation of and interaction with the environment, transmitted orally across generations.

Climate zones are systems that categorize the world's climates. A climate classification may correlate closely with a biome classification, as climate is a major influence on life in a region. The most used is the Köppen climate classification scheme first developed in 1884.

There are several ways to classify climates into similar regimes. Originally, climes were defined in Ancient Greece to describe the weather depending upon a location's latitude. Modern climate classification methods can be broadly divided into genetic methods, which focus on the causes of climate, and empiric methods, which focus on the effects of climate. Examples of genetic classification include methods based on the relative frequency of different air mass types or locations within synoptic weather disturbances. Examples of empiric classifications include climate zones defined by plant hardiness, evapotranspiration, or associations with certain biomes, as in the case of the Köppen climate classification. A common shortcoming of these classification schemes is that they produce distinct boundaries between the zones they define, rather than the gradual transition of climate properties more common in nature.

Religious studies, also known as religiology or the study of religion, is the study of religion from a historical or scientific perspective. There is no consensus on what qualifies as religion and its definition is highly contested. It describes, compares, interprets, and explains religion, emphasizing empirical, historically based, and cross-cultural perspectives.

While theology attempts to understand the transcendent or supernatural according to traditional religious accounts, religious studies takes a more scientific and objective approach, independent of any particular religious viewpoint. Religious studies thus draws upon multiple academic disciplines and methodologies including anthropology, sociology, psychology, philosophy, and history of religion.

Perceptual dialectology is the scientific study of how ordinary individuals perceive variation in language—where they believe it exists, where they believe it comes from, how they believe it functions, and how they socially evaluate it.

Perceptual dialectology differs from ordinary dialectology in that it is concerned not with empirical linguistic understandings or discoveries about language itself, but rather with empirical research on how non-linguists perceive language, also known as folk linguistics, which includes how non-linguists perceive various accents, vocabulary usages, grammatical structures, etc. Such perceptions may or may not align with actual linguistic findings. Perceptual dialectology falls under the general field of sociolinguistics.

In philosophy, a process ontology refers to a universal model of the structure of the world as an ordered wholeness. Such ontologies are fundamental ontologies, in contrast to the so-called applied ontologies. Fundamental ontologies do not claim to be accessible to any empirical proof in itself but to be a structural design pattern, out of which empirical phenomena can be explained and put together consistently. Throughout Western history, the dominating fundamental ontology is the so-called substance theory. However, fundamental process ontologies have become more important in recent times, because the progress in the discovery of the foundations of physics has spurred the development of a basic concept able to integrate such boundary notions as "energy," "object", and those of the physical dimensions of space and time.

In computer science, a process ontology is a description of the components and their relationships that make up a process. A formal process ontology is an ontology in the knowledge domain of operations. Often such ontologies take advantage of the benefits of an upper ontology. Planning software can be used to perform plan generation based on the formal description of the process and its constraints. Numerous efforts have been made to define a process/planning ontology.

Human science (or human sciences in the plural) studies the philosophical, biological, social, justice, and cultural aspects of human life. Human science aims to expand the understanding of the human world through a broad interdisciplinary approach. It encompasses a wide range of fields - including history, philosophy, sociology, psychology, justice studies, evolutionary biology, biochemistry, neurosciences, folkloristics, and anthropology. It is the study and interpretation of the experiences, activities, constructs, and artifacts associated with human beings. The study of human sciences attempts to expand and enlighten the human being's knowledge of its existence, its interrelationship with other species and systems, and the development of artifacts to perpetuate the human expression and thought. It is the study of human phenomena. The study of the human experience is historical and current in nature. It requires the evaluation and interpretation of the historic human experience and the analysis of current human activity to gain an understanding of human phenomena and to project the outlines of human evolution. Human science is an objective, informed critique of human existence and how it relates to reality.Underlying human science is the relationship between various humanistic modes of inquiry within fields such as history, sociology, folkloristics, anthropology, and economics and advances in such things as genetics, evolutionary biology, and the social sciences for the purpose of understanding our lives in a rapidly changing world. Its use of an empirical methodology that encompasses psychological experience in contrasts with the purely positivistic approach typical of the natural sciences which exceeds all methods not based solely on sensory observations. Modern approaches in the human sciences integrate an understanding of human structure, function on and adaptation with a broader exploration of what it means to be human. The term is also used to distinguish not only the content of a field of study from that of the natural science, but also its methodology.

The second law of thermodynamics is a physical law based on universal empirical observation concerning heat and energy interconversions. A simple statement of the law is that heat always flows spontaneously from hotter to colder regions of matter (or 'downhill' in terms of the temperature gradient). Another statement is: "Not all heat can be converted into work in a cyclic process." These are informal definitions, however; more formal definitions appear below.

The second law of thermodynamics establishes the concept of entropy as a physical property of a thermodynamic system. It predicts whether processes are forbidden despite obeying the requirement of conservation of energy as expressed in the first law of thermodynamics and provides necessary criteria for spontaneous processes. For example, the first law allows the process of a cup falling off a table and breaking on the floor, as well as allowing the reverse process of the cup fragments coming back together and 'jumping' back onto the table, while the second law allows the former and denies the latter. The second law may be formulated by the observation that the entropy of isolated systems left to spontaneous evolution cannot decrease, as they always tend toward a state of thermodynamic equilibrium where the entropy is highest at the given internal energy. An increase in the combined entropy of system and surroundings accounts for the irreversibility of natural processes, often referred to in the concept of the arrow of time.

In the sciences and in historiography, denialism is the rejection of basic facts and concepts that are undisputed, well-supported parts of the scientific consensus or historical record on a subject, in favor of ideas that are radical, controversial, or fabricated. Examples include Holocaust denial, AIDS denialism, and climate change denial. The forms of denialism present the common feature of the person rejecting overwhelming evidence and trying to generate political controversy in attempts to deny the existence of consensus.

In psychology, denialism is a person's choice to deny reality as a way to avoid believing in an uncomfortable truth. Denialism is an essentially irrational human behavior that withholds the validation of a historical experience or event when a person refuses to accept an empirically verifiable reality.
