{{Science}}
The following [[Outline (list)|outline]] is provided as a topical overview of [[science]]; the discipline of science is defined as both the systematic effort of acquiring knowledge through observation, experimentation and reasoning, and the body of knowledge thus acquired, the word "science" derives from the Latin word ''[[:wikt:scientia|scientia]]'' meaning knowledge. A practitioner of science is called a "scientist". Modern science respects [[Objectivity (philosophy)|objective]] logical reasoning, and follows a set of core procedures or rules to determine the nature and underlying natural laws of all things, with a scope encompassing the entire [[universe]]. These procedures, or rules, are known as the [[#Scientific method|scientific method]]. 

{{TOC limit|3}}

== Essence of science ==
* [[Research]] – systematic investigation into existing or new knowledge.
* [[Scientific discovery]] – observation of new phenomena, new actions, or new events and providing new reasoning to explain the knowledge gathered through such observations with previously acquired knowledge from abstract thought and everyday experiences.
* [[Laboratory]] – facility that provides controlled conditions in which scientific research, experiments, and measurement may be performed.
* [[Objectivity (science)|Objectivity]] – the idea that scientists, in attempting to uncover truths about the natural world, must aspire to eliminate personal or cognitive biases, a priori commitments, emotional involvement, etc.
* [[Inquiry]] – any process that has the aim of augmenting knowledge, resolving doubt, or solving a problem.

== Scientific method ==
[[Scientific method]] ([[Outline of scientific method|outline]]) – body of techniques for investigating phenomena and acquiring new knowledge, as well as for correcting and integrating previous knowledge. It is based on observable, empirical, measurable evidence, and subject to laws of reasoning, both deductive and inductive.
* [[Empirical method]] –
* Experimental method – The steps involved to produce a reliable and logical conclusion include:
*# Conducting initial research and asking a question about a natural [[phenomenon]]
*# Making observations of the phenomenon and/or collecting data about it
*# Forming a [[hypothesis]] – proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. 
*# [[Predicting]] a logical consequence of the hypothesis
*# Testing the hypothesis through an experiment – methodical procedure carried out with the goal of verifying, falsifying, or establishing the validity of a hypothesis. The 3 types of scientific experiments are:
*#* [[Controlled experiment]] – experiment that compares the results obtained from an experimental sample against a control sample, which is practically identical to the experimental sample except for the one aspect the effect of which is being tested (the independent variable).
*#* [[Natural experiment]] – empirical study in which the experimental conditions (i.e., which units receive which treatment) are determined by nature or by other factors out of the control of the experimenters and yet the treatment assignment process is arguably exogenous. Thus, natural experiments are observational studies and are not controlled in the traditional sense of a randomized experiment.
*#** [[Observational study]] – draws inferences about the possible effect of a treatment on subjects, where the assignment of subjects into a treated group versus a control group is outside the control of the investigator.
*#* [[Field experiment]] – applies the scientific method to experimentally examine an intervention in the real world (or as many experimentalists like to say, naturally occurring environments) rather than in the laboratory.  See also [[field research]].
*# Gather and analyze data from experiments or observations, including indicators of [[uncertainty]].
*# Draw [[logical consequence|conclusion]]s by comparing data with predictions.  Possible outcomes:
*#* Conclusive:
*#** The hypothesis is falsified by the data.  
*#** Data are consistent with the hypothesis.
*#** Data are consistent with alternative hypotheses. 
*#* Inconclusive:
*#** Data are not relevant to the hypothesis, or data and predictions are [[Commensurability (philosophy of science)|incommensurate]].
*#** There is too much uncertainty in the data to draw any conclusion.
*# Further steps include [[peer review]] and enabling others to reproduce or [[Falsifiability|falsify]] the observations and/or conclusions
* [[Deductive-nomological model]]
* [[Scientific modelling]] –
* Models of scientific method
** [[Hypothetico-deductive model]] – proposed description of scientific method. According to it, scientific inquiry proceeds by formulating a hypothesis in a form that could conceivably be falsified by a test on observable data. A test that could and does run contrary to predictions of the hypothesis is taken as a falsification of the hypothesis. A test that could but does not run contrary to the hypothesis corroborates the theory.

== Branches of science ==
{{See also|Index of branches of science|List of words with the suffix -ology}}

[[Branches of science]] – divisions within science with respect to the entity or system concerned, which typically embodies its own [[terminology]] and [[nomenclature]]. The most traditional data structure used for organizing the subfields of science is the "tree of knowledge", hence the idea of different scientific "branches". But over time, several other taxonomic systems have also been proposed for that purpose (such as networks, tables or circular schemes).<ref>[https://atlas-disciplines.unige.ch/ Sandoz, R. (ed.), ''Interactive Historical Atlas of the Disciplines'', University of Geneva]</ref>

=== Formal science ===
[[Formal science]] – branches of knowledge that are concerned with formal systems, such as those under the branches of logic, mathematics, computer science, statistics, and some aspects of linguistics. Unlike other sciences, the formal sciences are not concerned with the validity of theories based on observations in the real world, but instead with the properties of formal systems based on definitions and rules.
* [[Outline of formal science|Branches of formal science]] (also known as the formal sciences)

=== Natural science ===
[[Natural science]] ([[Outline of natural science|outline]]) – a major branch of science that tries to explain and predict nature's phenomena, based on empirical evidence. In natural science, hypotheses must be verified scientifically to be regarded as scientific theory. Validity, accuracy, and social mechanisms ensuring quality control, such as peer review and repeatability of findings, are among the criteria and methods used for this purpose. Natural science can be broken into two main branches: biology and physical science. Each of these branches, and all of their sub-branches, are referred to as natural sciences.
* [[Branches of natural science]] (also known as the natural sciences)

=== Social science ===
{{main|Outline of social science}}
[[Social science]] – study of the social world constructed between humans. The social sciences usually limit themselves to an anthropomorphically centric view of these interactions with minimal emphasis on the inadvertent impact of social human behavior on the external environment (physical, biological, ecological, etc.). 'Social' is the concept of exchange/influence of ideas, thoughts, and relationship interactions (resulting in harmony, peace, self enrichment, favoritism, maliciousness, justice seeking, etc.) between humans. The scientific method is used in many social sciences, albeit adapted to the needs of the social construct being studied.
* [[Branches of social science]] (also known as the social sciences)

=== Applied science ===
[[Applied science]] – branch of science that applies existing scientific knowledge to develop more practical applications, including inventions and other technological advancements.
* [[Branches of applied science]] (also known as the applied sciences)

=== Philosophy ===

*[[Epistemology]]
*[[Formal system]]
