Computer Science Stack Exchange is a question and answer site for students, researchers and practitioners of computer science. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. I am studying Computation complexity using Papadimitrious's book: "Computational Complexity". While doing Problem 7. scientific theory defintionA scientific theory is an explanation of an aspect of the natural world and universe that can be repeatedly tested and verified in accordance with the scientific methodusing accepted protocols of observationmeasurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment. Established scientific theories have withstood rigorous scientific theory defintion and embody scientific knowledge. A scientific theory differs from a scientific fact or scientific law in that a theory explains "why" or "how": a fact is a simple, basic observation, whereas a law is a statement often a mathematical equation about a relationship between facts. Facts are the world's data.

Theories are structures of ideas that explain and interpret facts. The meaning of the term scientific theory often contracted to theory for brevity as used in the disciplines of science is significantly different from the common vernacular usage of theory.
dedintion The strength of a scientific theory is related to the diversity of phenomena it can explain and its simplicity. As additional scientific evidence is gathered, a scientific theory may be modified and ultimately rejected if it cannot be made to fit source new findings; in such circumstances, a more accurate theory is then required.

Some theories are so well-established that they are unlikely ever to scientific theory defintion fundamentally changed for example, scientific theories such as evolutionheliocentric theorycell theorytheory of plate tectonicsgerm theory of diseaseetc. In certain cases, a scientific theory or scientific law that fails to fit all data can still be useful due to its simplicity as an approximation under specific conditions.
An example is Newton's laws of motionwhich are a highly accurate approximation to special relativity at velocities that are small relative to the speed of light. Scientific theories scientfic testable and make falsifiable predictions. As with other forms of scientific knowledge, scientific theories are both deductive eefintion inductive[8] aiming for predictive and explanatory power.
Scientists use theories to further scientific knowledge, as well as to facilitate advances in technology or scientific theory defintion. Albert Einstein described two types of scientific theories: "Constructive theories" and "principle theories".
Constructive theories are constructive models for phenomena: for example, kinetic theory. Principle theories are empirical generalisations such as Newton's laws of motion. Typically for any theory scientific theory defintion be accepted within most academia there is one simple criterion. The essential criterion is that the theory must be observable and repeatable. The aforementioned criterion is essential to prevent fraud hteory perpetuate science itself. The defining characteristic of all scientific knowledge, including theories, is the ability to make falsifiable or testable predictions. The relevance and specificity of those predictions determine how potentially useful the theory is.

A would-be theory that makes no observable predictions is not a scientific theory at all. Predictions not sufficiently specific to be tested are similarly not useful.
In both cases, the term "theory" is not applicable. A body of descriptions of knowledge can be called a theory if it fulfills the following criteria:.]
