What did Kurt Gödel contribute to mathematics?
Kurt Gödel (1906-1978) was probably the most strikingly original and important logician of the twentieth century. He proved the incompleteness of axioms for arithmetic (his most famous result), as well as the relative consistency of the axiom of choice and continuum hypothesis with the other axioms of set theory.
What was Kurt Gödel famous for?
By the age of 25 Kurt Gödel had produced his famous “Incompleteness Theorems.” His fundamental results showed that in any consistent axiomatic mathematical system there are propositions that cannot be proved or disproved within the system and that the consistency of the axioms themselves cannot be proved.

What is the main idea of Gödel’s incompleteness theorem?
Gödel’s first incompleteness theorem says that if you have a consistent logical system (i.e., a set of axioms with no contradictions) in which you can do a certain amount of arithmetic 4, then there are statements in that system which are unprovable using just that system’s axioms.
What did Alonzo Church prove?
Mathematical work Church is known for the following significant accomplishments: His proof that the Entscheidungsproblem, which asks for a decision procedure to determine the truth of arbitrary propositions in a first-order mathematical theory, is undecidable. His proof that Peano arithmetic is undecidable.
Why did Gödel starve himself?
He refused to eat any meals that had not first been tasted by his wife. However, when she became ill in 1977 and had to be hospitalized for six months, Gödel simply refused to eat anything at all, effectively starving himself to death.
Who was Euclidean geometry named after?

What does axiom mean in math?
In mathematics or logic, an axiom is an unprovable rule or first principle accepted as true because it is self-evident or particularly useful. “Nothing can both be and not be at the same time and in the same respect” is an example of an axiom.
What is Gödel’s incompleteness theorem and how did its discovery affect the mathematics world?
The first incompleteness theorem states that no consistent system of axioms whose theorems can be listed by an effective procedure (i.e., an algorithm) is capable of proving all truths about the arithmetic of natural numbers. …
What are some of the implications of Gödel’s theorem?
The implications of Gödel’s incompleteness theorems came as a shock to the mathematical community. For instance, it implies that there are true statements that could never be proved, and thus we can never know with certainty if they are true or if at some point they turn out to be false.
What does the Church-Turing thesis say?
The Church-Turing thesis (formerly commonly known simply as Church’s thesis) says that any real-world computation can be translated into an equivalent computation involving a Turing machine.
Is Church-Turing thesis a theorem?
Turing’s thesis: Turing’s thesis that every function which would naturally be regarded as computable is computable under his definition, i.e. by one of his machines, is equivalent to Church’s thesis by Theorem XXX.
What is the contribution of Subrahmanyan Chandrasekhar?
