A theorem is a step in a mathematical theory that allows, starting from hypotheses, to demonstrate rigorously some conclusion.
A theory is composed by five elements in general
- axioms;
- primary entities;
- logical rules;
- derived entities;
- theorems.
axioms and primary entities are the base of the theory: they are objects that are not defined from within the theory and relationships among these objects that are simply assumed three.
In standard geometry the point, the straight line, the plane are primary objects while the assumption that the straight line that passes y two given points always exists and it is unique is an axiom.
Every theory starts from axioms and primary objects. Logical rules are the rules that are assumed to guarantee that, if premises are true, the consequences derived using such rules are also true. Standard logical rules are generally assumed like
A=B => B=A
and the so. In mathematics standard mathematical demonstration rules like the modus ponens are also adopted. In selected theories, probability rules are also used as logical rules.
Derived objects are objects defined inside the theory, like the triangle or the polygon in standard geometry.
We have just see what a theorem is: it is the instrument allowing to derive new properties from objects axioms and already derived properties.
If we deal with a scientific theory, like a physical theory, a mathematical structure is not enough to use the theory to interpret nature. We must have the so called interpretation scheme allowing us to translate experimental results into relationships between the objects of the theory and back.
For example we must connect the theory object we call electron, with its properties like the motion equation, the charge and so on, with experimental observations like interference figures in electrons beam experiments that we interpret at the theory light as the sign of electrons presence.
Difference between first shifting and second shifting theorem
What is the difference between standard theory and extended standard theory?
A postulate is assumed to be true while a theorem is proven to be true. The truth of a theorem will be based on postulates.
From Wikipedia:In mathematics, a theorem is a statement proved on the basis of previously accepted or established statements.Definitively speaking, a theory is a unifying principle that explains a body of facts and the laws based on them. In other words, it is an explanation to a set of observations. Additionally, in contrast with a theorem the statement of the theory is generally accepted only in some tentative fashion as opposed to regarding it as having been conclusively established."Basically speaking, the major difference is that a theoryis not "conclusively established", whereas a theorem is.
Between Scientific Theory and what?
An axiom is a self-evident statement that is assumed to be true. A theorem is proved to be true.
The difference in the distance formula and the pythagorean theorem is that the distance formula finds the distance between two points while the pythagorean theorem usually finds the hypotenuse of a right triangle.
no difference! But there's not such a scientific theory. It's a lyric... I think
what are the difference between relevance and irrelevance theories of dividends
One cannot have a theory (theorem) without proof. Theories are explanations (models with uses such as predicting on outcome of an experiment or event) for scientific laws, which only describe the phenomenon. Proof is anything that backs up a hypothesis. When a significant amount of proof is shown, the hypothesis becomes a theory due to it being accepting by the scientific community.
Hypothesis is a guess a theory is an answer
No it would be a theorem if it was proven.
