Epistemology is the branch of philosophy that examines the nature, origin, and limits of knowledge.Also called "theory of knowledge", it explores different types of knowledge, such as propositional knowledge about facts, practical knowledge in the form of skills, and knowledge by acquaintance as a familiarity through experience.
Established scientific theories have withstood rigorous scrutiny and embody scientific knowledge. A scientific theory differs from a scientific fact or scientific law in that a theory seeks to explain "how" or "why", whereas a fact is a simple, basic observation and a law is an empirical description of a relationship between facts and/or other ...
It examines the nature of knowledge and justification, how knowledge arises, and what value it has. Further topics include the different types of knowledge and the limits of what can be known. [13] Despite agreements about the general characteristics of knowledge, its exact definition is disputed.

Quine concludes that studies of scientific knowledge concerned with meaning or truth fail to achieve the Cartesian goal of certainty. The failures in the reduction of mathematics to pure logic imply that scientific knowledge can at best be defined with the aid of less certain set-theoretic notions.
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. [1] [2] Modern science is typically divided into two or three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the social sciences (e.g., economics, psychology, and sociology), which ...
Cohen says scientific knowledge is less certain than it is usually portrayed, and that science and knowledge generally is not the 'very sensible and reassuringly solid sort of affair' that Kuhn describes, in which progress involves periodic paradigm shifts in which much of the old certainties are abandoned in order to open up new approaches to ...
The scientific revolution, which began to take hold in the 17th century, represented a sharp break from Aristotelian modes of inquiry. [66] One of its principal advances was the use of the scientific method to investigate nature. Data was collected, and repeatable measurements were made in experiments. [67]
