	Gödel’s incompleteness theorem
		An axiomatic system consists of some undefined terms, a number of axioms referring to those terms and partially describing their properties, and a rule or rules for deriving new propositions from already existing propositions.
		An axiomatic system is said to be consistent if, given the axioms and the derivation rules, it doesn't lead to any contradictory propositions.
		One of the first modern axiomatic systems was a formalization of simple arithmetic (adding and multiplying whole numbers), achieved the great logician Giuseppe Peano and now known as Peano arithmetic.

	Axiom - Wikipedia, the free encyclopedia
		To axiomatize a system of knowledge is to show that all of its claims can be derived from a small set of sentences that are independent of one another.
		Thus, an axiom is an elementary basis for a formal logic system that together with the rules of inference define a deductive system.
		The idea that alternative mathematical systems might exist was very troubling to mathematicians of the 19th century and the developers of systems such as Boolean algebra made elaborate efforts to derive them from traditional arithmetic.

		This project introduces the students to axiomatic systems by having the students generate their own axiomatic system for justifying some formulas for the area of polygonal regions in the plane.
		Axiomatic systems are introduced in a lecture give between the first and second project, and the second project has each group to develop an axiomatic system for area.
		In the third project, they test to see if the axiomatic system is valid on a sphere and to derive a formula for the area of a triangle on a sphere.

	Axiomatic Design of Software
		The flow chart for system architecture is generated as a result of the existence of the axiomatic design framework - in contrast to a heuristic approach that depends solely on the intuitive ideas and skills of individual software programmers.
		The system architecture and the flow diagram can be used to identify all the related modules that must be changed when a single change in the system architecture is proposed.
		Igata (1996) investigated the use of axiomatic design theory for the specific case of developing software for the ABS, which cannot be fully specified from the beginning because of the complicated physical environment that the vehicle experiences during its lifetime.

	Gödel's Incompleteness Theorem
		His proposal was to use a special, restricted, part of mathematics-- a part that could be axiomatized by a much weaker system of axioms than the one he was trying to justify, and of whose correctness not even Brouwer had any doubts-- to prove the goodness of a more general system of set theory.
		Proofs in formalized axiomatic systems, after all, are finite sequences of finite sequences of symbols from a finite "alphabet." Statements about such proofs-- such as the desired metamathematical theorem to the effect that no proof starting from your favorite system has
		Less metaphorically: an axiomatic system fulfilling Hilbert's positive and negative desiderata will *not* be able to prove the statement that it satisfies the negative one: it won't be able to prove that it is not totally incoherent, won't be able to prove that it does not yield a proof of

		In modern axiomatic systems points, lines, and planes are left as undefined and the axioms specify relationships between the points, lines, and planes.
		One constructs a model of an axiomatic system by finding an interpretation of the undefined terms using a collection of objects that one has an understanding of and that stand in relation to one another in the manner specified by the axioms.
		In order to test the independence of a statement in relation to a given axiom system, one procedure is to construct two models: one which satisfies the axioms and the statement and another that satisfies the axioms and the negation of the statement.

	CULTURAL HERITAGE AND CONTEMPORARY CHANGE
		The intention that lead Hilbert to construct his axiomatic system was to represent the structure of Euclidean space by purely conceptual means and to divorce geometry from intuition.
		The reason for this was that he constructed it as an axiomatic system in the contemporary sense and based it on a notion of spatial intuition that was restricted to a limited region of space.
		The axiomatic system is here understood as a set of sentences of the form ‘If A, then T’ whereby A is the set of the axioms of the theory and T any theorem.

		Independence is not a necessary requirement for a system, yet consistency is necessary.
		An axiomatic system will be called complete if no additional axiom can be added to the system without making the new system either dependent or inconsistent.
		An axiomatic system for which every model is isomorphic to another is called categorial, and the property of categoriallity ensures the completeness of a system.

		The system carries out many such activities in parallel, distributes its resources among the them in a time-sharing manner, and dynamically adjusts the distribution according to the feedback of each step.
		A new approach, Non-Axiomatic Reasoning System, is introduced, which is built under the assumption that the system's knowledge and resources are usually insufficient to handle the tasks imposed by the environment.
		Abstract: In a probability-based reasoning system, Bayes' theorem and its variations are often used to revise the system's beliefs.

		The axiomatic method is a procedure by which we prove the truth of the results discovered by trial and error.

	Gottlob Frege [Internet Encyclopedia of Philosophy]
		He invented modern quantificational logic, and created the first fully axiomatic system for logic, which was complete in its treatment of propositional and first-order logic, and also represented the first treatment of higher-order logic.
		However, the core of the system of the Grundgesetze, that is, the system minus the axioms governing value-ranges, is consistent and, like the system of the Begriffsschrift, is complete in its treatment of propositional logic and first-order predicate logic.
		In earlier logical systems such as that of Boole, in which the propositional and quantificational elements were bifurcated, the connection was wholly lost.

		Since this is the case in the level of the axiomatic framework itself, it must be true for any product, which is based on a non-finite collection.
		And since this is the case in the level of the axiomatic system itself, then any non-finite collection MUST BE incomplete in order to exist (= to be consistent).
		Gödel's incompleteness theorems clearly show us that any axiomatic system is actually an open framework, which can be deeply changed when deeper insights of its fundamental concepts are invented/discovered by its speakers.

	Chaitin, The Limits of Mathematics
		And Hilbert emphasized that the whole point of a formal axiomatic system is that there must be a mechanical procedure for checking whether a purported proof is correct or not, whether it obeys the rules or not.
		He believed that he would be able to set down a consistent and complete formal axiomatic system for all of mathematics and from it obtain a decision procedure for all of mathematics.
		Well, remember that the essence of a formal axiomatic system is a mechanical procedure for checking whether a formal proof follows the rules or not.

		So I'll think of a formal axiomatic system as a computation which starts running and every now and then it throws out a LISP expression that it claims it's demonstrated is elegant.
		Then it starts running the formal axiomatic system looking for the first elegant LISP expression that is larger than it is. Once it finds this elegant LISP expression, it runs it to get the value of the elegant expression, and then it returns this value as its own final value.
		It's given a formal axiomatic system, it measures its size and adds 410 to that, which happens to be the right way to calculate the exact size of the entire LISP expression.
