  Hilbert's Program (Stanford Encyclopedia of Philosophy)
Hilbert never gave a general account of which operations and methods of proof are acceptable from the finitist standpoint, but only examples of operations and methods of inference in contentual finitary number theory which he accepted as finitary.
Although Hilbert's first proposals focused exclusively on consistency, there is a noticeable development in Hilbert's thinking in the direction of a general reductivist project of a sort quite common in the philosophy of science at the time (as was pointed out by Giaquinto 1983).
Hilbert's proof theoretic program can then be seen to be a search for a proof theoretic reduction of all of mathematics to finitary mathematics; in a relativized program one looks for reductions of theories weaker than all of classical mathematics to theories often stronger than finitary mathematics.

  David Hilbert - Wikipedia, the free encyclopedia
Hilbert's basis theorem solved the principal problem in nineteenth century invariant theory by showing that any form of a given number of variables and of a given degree has a finite, yet complete system of independent rational integral invariants and covariants.
Hilbert helped provide the basis for the theory of automata which was later built upon by computer scientist Alan Turing.
In 1920 he proposed explicitly a research project (in metamathematics, as it was then termed) that became known as Hilbert's program.

 Hilbert's Program Summary - Hilbert's Program Information
Hilbert's program, as his initiative as come to be called, was a call to the mathematics community to formalize the basic tenets of the science.
Hilbert viewed the new century with great optimism for the study of mathematics, feeling that the 23 unsolved problems demonstrated both the vitality of the field and the opportunity for growth and innovation within it.
Hilbert further stated that many problems of mathematics were born of the intertwined relationship between pure reason and the reality of observation and intuition.

 From Frege To Godel: von Heijenoort   (Site not responding. Last check: 2007-10-25)
Hilbert popularized his program to found mathematics on a logic which can be shown consistent by finitistic methods.
Hilbert had already provided axioms for geometry and for the real numbers and shown that the consistency of geometry can be reduced to that of the real-number system.
Hilbert and Bernays [1939] carried out the details of Godel's second incompleteness theorem for two number theory systems Z_mu and Z. Godel [1934] made precise the notion of general recursive functions as functions uniquely determined by equations among terms involving known (recursive) functions and the unknown function (following a suggestion by Herbrand).

 Boston.com / Business / Conseco barred from freezing ex-CEO assets
Hilbert and more than 150 former Conseco executives, directors and key employees took loans in the late 1990s to buy Conseco stock in a company-sponsored program of a type now prohibited.
Hilbert argues Conseco's shift to new board management and ownership during its Sept. 10 emergence from bankruptcy triggered a "change of control" clause shielding him from repayment obligations.
Hilbert and others were unable to repay the loans when Conseco shares tumbled after reaching a high of $58 in 1998.

 Some observations about Hilbert   (Site not responding. Last check: 2007-10-25)
Hilbert was invited to give a special address to the Second International Congress of Mathematicians at Paris in 1900.
Hilbert was adamently opposed to the position of an earlier mathematician named Kronecker who had insisted that only constructive mathematics was appropriate.
Hilbert granted that mathematics could be more rigorous, but insisted we could do this by using a formal axiomatic method.

 M. E. Szabo: The Collected Works of Gerhard Gentzen   (Site not responding. Last check: 2007-10-25)
After developing and examining the 'natural calculus' Gentzen conjectured that proofs should have a "normal form" in which "all concepts required for the proof would in some sense appear in the conclusion of the proof." This is the subformula property.
This necessitated a reconsideration of the notion of the consistency proofs called for by Hilbert's program in light of Godel's second incompleteness theorem.
Hilbert agrees with Kant in the sense that the symbols used in mathematics are objects of "immediate experience." This corresponds to Hilberts finitist view of formalist mathematics (which Gentzen helped develop).

 Understanding the Ideas of Gregory Chaitin: A Serious Problem with Reality   (Site not responding. Last check: 2007-10-25)
According to Hilbert, a systematic search for meaningful statements in mathematics or well formed formulae and their proof in mathematics is a pursuit that is both possible and realistic.
Thirty-one years after Hilbert’s speech in Paris Russell and Whitehead are found desperately working on the fourth volume of Principia Mathematica.   With a crash Hilbert’s program is wrecked by a stunting upset theorem developed by Kurt Gödel.  This result would shake the very foundations of mathematics.
Hilbert’s program would require a result in the decision problem, information.  In other words, if you put the algorithm to the test and you ran through all the well formed formulae, a decision on a statement’s  provability necessarily results.

 Hilberts' moving sale is anything but ordinary
The Hilberts are moving from the 23,000-square-foot Le Chateau Renaissance, sitting on 40 acres and appraised for $25 million, to a 14,000-square-foot home in the Carmel gated community of Laurelwood.
Stephen Hilbert offered to vacate the mansion to win a stay of a judge's ruling that would require him to pay $72 million to Conseco, the insurance company he co-founded and led until 2000.
Hilbert has argued that the debt was nullified for several reasons, including that the ownership of Conseco has changed and that the loan programs, which are now forbidden by law, were illegal.

 Journal of TeeJay (2309)
I just spent 45 minutes in gdb trying to figure out why my C++ program was repeatedly segfaulting, after adding breakpoints, stepping through, and adding lots of cout statements printing all the values I finally discovered that where I expected calls to the getCoordinateFromPoint(int point) method I was geting $BIG_NEGATIVE_NUM rather than 1 to 4.
Even using strict wouldn't have caught that, in C and C++ I must remember to initialise all values to 0 when declaring them unless I want to pass around random junk when I use the wrong variable, easier to trace that than segfaults.
Anyway, just before getting off the train I managed to run a test program using the class and killed my machine twice in a row because the code went into a fast infinate loop.

 Hilbert's Tenth Problem. Diophantine Equations. By K.Podnieks
Given a Diophantine equation with any number of unknowns and with rational integer coefficients: devise a process, which could determine by a finite number of operations whether the equation is solvable in rational integers.
The idea that problems like Hilbert's, maybe, have negative solutions could appear only in 1930s, when the notion of algorithm ("process, which could determine by a finite number of operations...") was formalized.
Thus, in 1961 the unsolvability of (modified) Hilbert's 10th problem for exponential Diophantine equations was proved.

One of the major deficiencies of the CC-40 is that when a Solid State Cartridge program is operated from the keyboard the results are brought to the display in a form that does not permit additional calculations on the result without reentering the value.
where the program completes the sum of the products in sequence and in essence throws away digits beyond the fourth digit to the right of the decimal point because of the larger magnitude of the first product.
Thanks for your hard work to get and post those interesting results, but may I suggest once again that using Hilbert matrices for such tests is actually a less than good idea and the three matrices I offered would actually be much better suited to the task.

 Kurt Grelling Biography
HILBERTs efforts to axiomatize mathematics were shaken, as were the entire foundations of mathematics, by the announcement in 1903 of Bertrand RUSSELLs antinomy or paradox.
BORN was HILBERTs assistant when GRELLING arrived and later a professor of physics at Göttingen and much later (in 1954) a Nobel Laureate in Physics.
Assisted by Paul BERNAYS, HILBERT revised the logical calculus of the Principia Mathematica (1910-1913) of Alfred North WHITEHEAD (1881-1947) and RUSSELL, and distinguished between mathematics proper and meta-mathematics (literally, about mathematics), the latter confined to finite means and concerned with proof theory (Beweistheorie).

When I looked at his program I concluded that it was a special purpose program which will calculate the determinant of a Hilbert matrix but has no obvious capability to calculate the determinant of a general matrix.
The Hilbert matrix entries are floating-point, and the determinant is calculated with floating-point arithmetic.
For a Hilbert matrix of order n, divide the determinant of this "integerized" matrix by the LCM of the denominators of the original Hilbert matrix, raised to the power n, and that will be the determinant of the original Hilbert matrix.
