What are the theories?
In science, a theory is an interconnected set of hypotheses, statements and propositions with the general purpose of explaining natural phenomena or more generally of systematically formulating the principles of a scientific discipline. ... For example, until recently black holes were considered theoretical.
A hypothesis is a proposed solution to an unexplained phenomenon, which is not currently covered by scientific theory. The basic idea of a hypothesis is that it is not a predetermined result. ... A hypothesis is usually formulated as an if / then sentence, suggests the University of California.
To come up with a theory, you have to follow the scientific method: first, make measurable predictions about why or how something works; then conduct a controlled experiment to test them; finally, establish whether the results of the experiment objectively confirm the hypotheses.
The falsifiability criterion therefore affirms that a theory, in order to be controllable, therefore scientific, must be "refutable": in logical terms, from its basic premises it must be possible to deduce the conditions of at least one experiment which, if the theory is wrong, can fully demonstrate ...
falsifiability, theory of the Conception on the basis of which a hypothesis or a theory has a scientific character only when it is susceptible to being disproved by the facts of experience. The main exponent of this theory is Popper (➔).
A (non-analytical) statement is verifiable in principle if and only if a conclusive proof of its truth (verification) or a conclusive proof of its falsity (falsification) is possible in principle through experience (see, for example , Carnap 1936-37).
Strong verifiability principle
This affirms that a judgment is meaningful only when it can be shown definitively true or false; that is, there must be an experience that can show this value of truth.
Ad hoc means "for this purpose" or "for this". ... In science, an ad hoc hypothesis is normally created with the intention of trying to prove what a proposed new theory cannot explain, preventing it from being discredited.
Theories are accepted when they are able to make correct experimental predictions and avoid the wrong ones, which therefore represent its validation or not.
The Problem of Induction: Popper states that induction exists neither as a scientific method nor in ordinary life. ... Popper is drastic: there is no inductive method, induction does not exist, neither in the scientific method, nor in any other cognitive field. The problem of induction is not solved, but dissolved.
(extens.) [abstract possibility and in any case not certain: your t's. they don't convince me] ≈ conjecture, hypothesis, supposition, thesis. ↔ certainty, as a matter of fact.
The theory is a system of postulates or axioms from which it is possible to logically deduce the experimental laws. A hypothesis is a theory not yet fully verified by experimental data. A model is an ideal and conceptual reproduction of a physical system, built to make an intuitive mental image of it.
The scientific method is the typical way in which science proceeds to reach an objective, reliable, verifiable and shareable knowledge of reality: it consists, on the one hand, in the collection of empirical data under the guidance of the hypotheses and theories to be tested; on the other hand, in the rigorous, logical analysis ...
- Make sure your guess matches up with your background information.
- Write a list of subjects to use for your hypotheses, and two or three ideas on how to test or verify each. Use the one you feel most confident about.
A hypothesis (from the ancient Greek ὑπόθεσις hypothesis, composed of hypo, "under" and thesis, "position", or supposition) is the premise underlying a reasoning or a demonstration.
set of ideas or guidance proposals, useful for setting up a project, a research and sim.
An experiment (from the Latin ex, "from", and perire, "groped", "go through") is the realization of an empirical operation aimed at confirming hypotheses or finding laws regarding an observable phenomenon in any area of knowledge (physics , chemistry, biology, geology, psychology, economics, etc.).
A law in science is a generalized rule for explaining a body of observations, in the form of a verbal or mathematical statement. Scientific laws (also known as natural laws) imply a cause and effect between the observed elements and must always apply under the same conditions.
In physics, the theory of everything, also known as TOE (acronym for the English theory of everything), is a hypothetical physical theory capable of explaining and bringing together all known physical phenomena in a single framework. The minimum prerequisite of this theory is the unification of all fundamental interactions.
Ad hoc: literally "for this", the expression is used with the meaning of "appropriate to the context" or "for the occasion". For example, "quoting an ad hoc verse" means referring a verse appropriate to the context of the speech.
Adoc is the National Association for the Defense and Consumer Orientation promoted by the UIL. ... The Adoc intervenes in numerous sectors, from telecommunications to the energy sector, from transport to the environment, from the banking-financial sector to insurance and the protection of privacy.
First of all what "ad hoc" means, this term is used to indicate something specific, created on purpose. As you may have guessed, the correct form is the one with "h", therefore "ad hoc", while the form without "a doc" is wrong.
Popper distinguishes between 'corroboration' and verification not to appear original at all costs. Verification is a typical procedure of empiricism, which does not 'falsify' a theory, therefore it does not subject it to the severe checks required by the logic of scientific discovery after Einstein.
epistemology Critical investigation of the logical structure and methodology of the sciences. The term, coined by the Scottish philosopher JF Ferrier, designates that part of gnoseology that studies the foundations, the validity, the limits of scientific knowledge (episteme).
The scientific method consists in the collection of data through observation and experiment in order to formulate hypotheses and theories. The scientific method is the way in which science investigates reality and is the most established method in the process of defining knowledge.
