Title: Wissenschaft
Content:  Although Wissenschaft and science were roughly comparable words in previous centuries, the word science in English "has narrowed its meaning incomparably, whereas Wissenschaft...has retained its broad meaning". In modern English, the word science refers to systematically acquired, objective knowledge that is about a particular subject (the workings of the natural world, including the people in it) and produced through a particular methodology (the scientific method), in a progressive, iterative process that builds on previous knowledge. Wissenschaft, by contrast, encompasses knowledge of objects as well as truths, such as what it means to be good. The difficulties of being precise about knowledge are one reason why English is not considered well-suited for discussions about epistemology, and terms from other languages, notably Latin and German, are commonly used. Some 19th-century Americans visiting German universities interpreted Wissenschaft as meaning "pure science," untainted by social purposes and opposed to the liberal arts. Some contemporary scientists and philosophers interpret Wissenschaft as meaning any true knowledge or successful method, including philosophical, mathematical, and logical knowledge and methods.
Title: Outline of science
Content:  The following 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 scientia meaning knowledge. A practitioner of science is called a "scientist". Modern science respects 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.
Title: Knowledge
Content:  The development of the scientific method has made a significant contribution to how knowledge of the physical world and its phenomena is acquired. To be termed scientific, a method of inquiry must be based on gathering observable and measurable evidence subject to specific principles of reasoning and experimentation. The scientific method consists of the collection of data through observation and experimentation, and the formulation and testing of hypotheses. Science, and the nature of scientific knowledge have also become the subject of philosophy. As science itself has developed, scientific knowledge now includes a broader usage in the soft sciences such as biology and the social sciences – discussed elsewhere as meta-epistemology, or genetic epistemology, and to some extent related to "theory of cognitive development". Note that "epistemology" is the study of knowledge and how it

Content:  concerning, in which the definition of knowledge itself is one of the subjects investigated. Philosophy is the pursuit of wisdom, spanning the nature of the Universe and human nature (of the mind and the body) as well as the relationships between these and between people. It explores what and how people come to know, including existence itself, and how that knowledge is reliably and usefully represented and communicated between and among humans, whether in thought, by language, or with mathematics. Philosophy is the predecessor and complement of science. It develops notions about the issues that underlie science and ponders the nature

Sir Francis Bacon was critical in the historical development of the scientific method; his works established and popularized an inductive methodology for scientific inquiry. His aphorism, "knowledge is power", is found in the Meditations Sacrae (1597). Until recent times, at least in the Western tradition, it was simply taken for granted that knowledge was something possessed only by humans – and probably adult humans at that. Sometimes the notion might stretch to Society-as-such, as in (e. g.) "the knowledge possessed by the Coptic culture" (as opposed to its individual members), but that was not assured either. Nor was it usual to consider unconscious knowledge in any systematic way until this approach was popularized by Freud.

Title: Models of scientific inquiry
Content:  Models of scientific inquiry have two functions: first, to provide a descriptive account of how scientific inquiry is carried out in practice, and second, to provide an explanatory account of why scientific inquiry succeeds as well as it appears to do in arriving at genuine knowledge. The search for scientific knowledge ends far back into antiquity. At some point in the past, at least by the time of Aristotle, philosophers recognized that a fundamental distinction should be drawn between two kinds of scientific knowledge—roughly, knowledge that and knowledge why. It is one thing to know that each planet periodically reverses the direction of its motion with respect to the background of fixed stars; it is quite a different matter to know why. Knowledge of the former type is descriptive; knowledge of the latter type is explanatory. It is explanatory knowledge that provides scientific understanding of the world. (Salmon, 2006, pg. 3) "Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work."
Title: Scientologie, Wissenschaft von der Beschaffenheit und der Tauglichkeit des Wissens
Content: "What is Knowing? What IS Knowledge? What can we know, what must we know about Knowledge/Knowing, to do justice to and to justify the world? The question is thus nothing less than self-knowing, determination of the nature of self, and also of self-realization and self-understanding of Knowledge/Knowing. Is this possible? If possible, how can the systemization of Knowledge/Knowing itself be accomplished? How can a Science of Knowledge/Knowing be produced?" "the world is nothing but knowledge, merely an extraction from knowing....Only out of the equally valued mutual operation of Knowledge/Knowing as shaper & creator, and world as created & shaped, is it possible to arrive at the true science of the world....Out

Title: Philosophy of science
Content:  The philosophy of astronomy seeks to understand and analyze the methodologies and technologies utilized by experts in the discipline, focusing on how observations made about space and astrophysical phenomena can be studied. Given that astronomers rely and utilize theories and formulas from other scientific disciplines, such as chemistry and physics, the pursuit of understanding how knowledge can be obtained about the cosmos, as well as the relation in which our planet and Solar System have within our personal views of our place in the universe, philosophical insights into how facts about space can be scientifically analyzed and configure with other established knowledge is a main point of inquiry.

Question: what word is used to describe knowledge about the universe and method of obtaining that knowledge?
Answer: epistemology.
Empiricism.
