  Kurt Godel
Kurt Godel (1906-1978), elected to Academy membership in 1955, was noted for his contributions to the foundations of logic and mathematics.
In a celebrated paper published in 1931, Godel first put forward what came to be known simply as "Godel's Theorem": In certain formal systems, there exist propositions that cannot be proved or disproved using the axioms of that system.
Godel's Theorem made a deep impact in the fields of mathematics and logic, and has been called the most significant mathematical truth of the 20th century.

Kurt Godel was a mathematician, logician, and mathematical philosopher who revolutionized mathematics by the creating what is known as the
At the age of 18 Kurt entered the university in Vienna.
It was in this dissertation that he presented the concept of the first-order predicate calculus(better known as Godel's completeness theorem).

 Godel's Incompleteness Theorem
Godel then points out that the following statement is a part of the system: a statement P which states "there is no proof of P".
Godel's proof is designed to emphasize that the statement P is *necessarily* a part of the system, not something arbitrary that someone dreamed up.
After showing the existence of that first "Godel" statement, Godel goes on to prove that there are an infinite number of Godel statements in the system, and that even if these were enumerated very carefully and added to the postulates of the system, more Godel statements would arise.

Mathematician-logician Kurt Godel (1906-1978) in 1931 proved that within a formal system questions exist that are neither provable nor disprovable on the basis of the axioms of that system.
This is known as "Godel's Undecidability Theorem" or "Incompleteness Theorem".
Godel's theorem has direct relevance for information theory and mathematical reasoning and is of great importance in complex systems.

Kurt Gödel's father was Rudolf Gödel whose family were from Vienna.
Kurt's mother, Marianne Handschuh, was from the Rhineland and the daughter of Gustav Handschuh who was also involved with textiles in Brünn.
Although there is no evidence that he did have a weak heart, Kurt became convinced that he did, and concern for his health became an everyday worry for him.

In 1931 the mathematician and logician Kurt Godel proved that within a formal system questions exist that are neither provable nor disprovable on the basis of the axioms that define the system.
In establishing these theorems Godel showed that there are problems that cannot be solved by any set of rules or procedures; instead for these problems one must always extend the set of axioms.
Alan Turing later provided a constructive interpretation of Godel's results by placing them on an algorithmic foundation: There are numbers and functions that cannot be computed by any logical machine.

 Kurt Godel Papers
The papers of Kurt Gödel (1906-1978), foremost mathematical logician of the twentieth century, were bequeathed by him to his wife Adele, who donated them to the Institute for Advanced Study in his memory prior to her death in 1981.
Kurt Friedrich Gödel was born April 28, 1906, in Brünn, Moravia, and died January 14, 1978, in Princeton, New Jersey.
The Papers of Kurt Gödel include documents spanning the years 1905-1980, with the bulk of the material falling between 1930 and 1970.

 Nat' Academies Press, Biographical Memoirs V.56 (1987)
Godel of- fered supplementary reasoning that adapted his treatment for the predicate calculus to the predicate calculus with equality, with "the domain {0, I, 2,...~" being replaced in his conclusions by "~0, I, 2,...) or a non-empty finite domain".
KURT GODEL 143 the axioms that the range of the variables in them constitutes a countable collection, contradicting the theorem of Cantor by which the subsets of {0, I, 2,...} (which are among the sets for his theory) constitute an uncountable collection.
Thus 1939b, commu- nicated by Godel on February 14, 1939, is put after 1939a, which is a set of notes by George W. Brown published in 1940 on lectures delivered by Godel in the fall term of 1938-39; and 1934 and 1946, only published in 1965, are in the right order.

Kurt Godel, the greatest logician of our era and the heir to Aristotle, is best known for having proved the incompleteness of arithmetic.
The rest of the book lays out Godel's early years and views, the mathematical and philosophical climate in which he was operating, a simplified version of the proof of Godel's theorem, and Godel's last, tragic years.
She ably describes the tension between Godel's ideas and those of Wittgenstein, as well as those of the formalists (though her discussion of the latter is to some extent marred by the same problems which plague her discussion of the positivists).

 KURT GODEL
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.
When his wife was incapacitated with illness, these factors combined to cause his death from self-starvation.

 Objectivism Without Platonism: Hao Wang on Kurt Godel
Kurt Gödel is most famous for Gödel's Theorem, also known as the Incompleteness Theorem.
However, his focus on projects, and on developing a worthy project for himself at a time when ambitious projects in philosophy were decidedly out of fashion, can make his thought somewhat scattered and unsystematic, although pregnant with possibilities.
Unlike Godel, Wang is not especially interested in establishing or strengthening the philosophical foundations for his views.

In 1931 Kurt Godel published a proof that claimed to reveal the kind of universe we inhabit.
Godel himself believed that mathematical objects have as much reality as those we perceive with our senses.
And the kind of universe that Godel's proof suggests is the one put forward by current cosmological modeling: an open-ended, infinite, eternal existence, requiring no beginning, in which our knowledge may become significant and extensive but never complete.

Kurt Godel is considered the twentieth century's greatest mathematician.
From the famous Vienna Circle and sparring with Wittgenstein to Princeton's Institute for Advanced Study, where he was Einstein's constant companion, Godel was both a towering intellect and a deeply mysterious figure, whose strange habits and ever-increasing paranoia led to his sad death by self-starvation.
Considered the 20th century's greatest mathematician, Kurt Godel is the subject of this lucid and accessible study, which explains the significance of his theorems and the remarkable vision behind them, while bringing this eccentric, tortured genius and his world to life.

Godel's proof is not easy to follow, nor easy to grasp the full implications of its conclusions.
Many mathematical texts, overviews, and historical summaries avoid directly discussing Godel's proof as these quotes indicate: "Godel's proof is even more abstruse than the beliefs it calls into question." "The details of Godel's proofs in his epoch-making paper are too difficult to follow without considerable mathematical training.

Wang, professor of logic at Rockefeller University, was personally acquainted with Godel in his last years, and relies on recollected conversations as well as published and unpublished material in this first extended treatment of Godel's life and work.
Known primarily as a mathematician/logician from his published work, Godel's extensive unpublished work, says Wang, contains "bold speculations on several perennial issues of universal concern." Those issues are only hinted at here, as most of the philosophical discussion concerns the philosophy of mathematics.
I understand that Wang has been an important source in compiling information on Godel and bringing it to public attention over the years, but this is the first book of his I've read.
