Christian Goldbach En 1725, Cristian Goldbach llegó a ser profesor de matemáticas e historiador en San Petersburgo.Después, en 1728, fue a Moscú para ser tutor del Zar Pedro II. Viajó por toda Europa entrevistándose con matemáticos tales como Leibniz, Nicolaus Bernoulli y sus hijos Daniel y Nicolaus, de Moibre y Hermann. Su más notorio trabajo en el campo de la teoría de números fue desarrollado en colaboración con Euler a traves del correo. Su principal aportación fue la conjetura que desarrollo en el margen de una de estas misivas escrita el día 7 de junio de 1742. En ella decía: "Todo número par puede ser expresado como la suma de dos primos y todo impar como la suma de tres primos" Goldbach también trabajo en el campo de la teoría de curvas, las sumas infinitas y la teoría de ecuaciones.

Some of the mystical atmosphere that surrounds them can be traced back to Pythagoras and his followers who formed secret brotherhoods in Greece, during the 5th Century BC. The Pythagoreans believed that numbers had spiritual properties. The discovery that some numbers such as the square root of 2 cannot be expressed exactly as the ratio of two whole numbers was so shocking to Pythagoras and his followers that they hushed up the proof!

Diese Seite auf Deutsch Introduction Historic computations Computational process Results ... Publication Introduction In his famous letter to Leonhard Euler dated June 7th 1742, Christian Goldbach first conjectures that every number that is a sum of two primes can be written as a sum of "as many primes as one wants". Goldbach considered 1 as a prime and gives a few examples. On the margin of his letter, he then states his famous conjecture that every number is a sum of three primes: This is easily seen to be equivalent to that every even number is a sum of two primes which is referred to as the (Binary) Goldbach Conjecture . Its weaker form, the Ternary Goldbach Conjecture states that every odd number can be written as a sum of three primes. The ternary conjecture has been proved under the assumption of the truth of the generalized Riemann hypothesis and remains unproved unconditionally for only a finite (but yet not computationally coverable) set of numbers. Although believed to be true, the binary Goldbach conjecture is still lacking a proof. . The program was distributed to various workstations. It kept track of maximal values of the smaller prime p in the minimal partition of the even numbers, where a minimal partition is a representation 2n = p + q with 2n - p' being composite for all p'

Ask A Scientist Mathematics Archive Goldbach Conjecture Author: jonathan j hoch What is the Goldbach Conjecture? Response #: 1 of 2 Author: asmith That every even number is the sum of two prime numbers. Response #: 2 of 2 Author: tee Christian Goldbach (1690-1764), in a letter to Euler dated February, 16, 1745, stated that every even number equal to or greater than 6 is the sum of two odd primes in one or more ways. The first sentence is a direct quote from THE LORE OF PRIME NUMBERS by G. P. Loweke, p 68. The conjecture remains unsettled, but computers have verified the conclusion for all even N below very large bounds (Loweke noted the bound of 100,000 but that is quite old, I believe). A related conjecture is that every even number is a difference of two primes in infinitely many ways! Loweke ascribes this statement to A. de Polignac around 1849.

52. Conj la congettura di goldbach (christian goldbach (1690-1764), amico di Eulero) http://web.unife.it/progetti/geometria/Mat2000/conj.htm

Problemi aperti, congetture. In matematica esiste l'arte di "fare congetture"; fare una congettura consiste nel dire "ecco c'è questo problema e penso che la risposta sia questa, però non sono capace di dimostrarlo". Per essere interessante una congettura deve riferirsi a un problema importante e la presunta risposta deve, in qualche modo, "spiegare il problema", gettare luce, aprire nuovi orizzonti; oppure la risposta proposta deve essere molto sorprendente (cf congettura di Goldbach). E' chiaro inoltre che una buona congettura non deve essere facilmente risolvibile (altrimenti rischia di diventare un semplice esercizio...). E' molto difficile fare una buona congettura e spesso chi le fa non le risolve! Le congetture in matematica sono molto importanti perchè indirizzano le ricerche, servono da guide. Le congetture più note sono in generale quelle che riguardano l'aritmetica, questo è anche dovuto al fatto che hanno enunciati comprensibili anche da non specialisti. Ecco un esempio classico: un numero naturale, n, è detto perfetto se 2n è uguale alla somma dei suoi divisori. Per esempio 6 è perfetto perchè i suoi divisori sono 1, 2, 3, 6 e 12 = 1+2+3+6. Il successivo numero perfetto è 28.

54. Goldbach's Conjecture finite number of exceptions. A slightly different form of these conjectureswas originally posed by christian goldbach, in 1742. http://www.jimloy.com/number/goldbach.htm

Return to my Mathematics pages Go to my home page Goldbach's Conjecture The modern version of Goldbach's Conjecture (called Goldbach's Strong Conjecture) is this: Every even number greater than 2 is the sum of two primes. Let's try a few: The conjecture is looking safe so far. Not only is each even number the sum of two primes, but the number of pairs of primes tends to increase. This trend seems to continue. But no one has ever proved that this goes on forever. All of the even number up to 400,000,000,000 have been tested, so far, with no exceptions found. Mathematicians have achieved some results in their efforts to prove (or disprove) this conjecture. In 1966, J. R. Chen showed that every sufficiently large even number is either the sum of two primes or of a prime and a near prime. A near prime is a number that is the product of two primes, like 91=7x13 or 4=2x2. No one knows just how large "sufficiently large" is. There is another Goldbach Conjecture, that every odd number greater than 5 is the sum of three primes. This is known as the Weak Goldbach Conjecture. This too has not been proved or disproved. It has been shown that if there are exceptions, then there are only a finite number of exceptions. A slightly different form of these conjectures was originally posed by Christian Goldbach, in 1742. Incidentally, if either Goldbach Conjecture is ever proven, then that would also prove that there are infinitely many primes. But we already knew that. See

58. Fermat S Last Theorem - Proofs For Special Cases were proven by Euler. In 1753 Euler wrote to christian goldbach aboutthe proof, but he did not publish it. In 1770, in his book http://fermat.workjoke.com/flt2.htm

Previous chapter: The birth of the problem Next chapter: First steps in general proofs Table of contents Proofs for special cases One of the methods used also by mathematicians in their struggle with hard problems is "Divide and Conquer" - splitting the problem into sub-problems that are easier to handle. This tactic appears in connection with FLT already in Fermat's writings, which contain a kernel of a proof for the special case n=4. This is the only proof in number theory that Fermat left (it had space in the margin of Diophantus' book), and it uses the infinite descent method. Fermat also dealt with the special case n=3, as we learn from his letter to Christian Hugeness, but, habitually, he did not leave a proof for this case. The proof for the special case n=3 was found one hundred years later by Leonhard Euler, the greatest mathematician of the eighteenth century. In number theory, Euler is the follower of Fermat: many theorems stated by Fermat were proven by Euler. In 1753 Euler wrote to Christian Goldbach about the proof, but he did not publish it. In 1770, in his book Anleitung zur Algebra (A Guide to Algebra), Euler gave a proof for this case. This proof was slightly different from the one he gave to Goldbach, and in it Euler used algebraic numbers, which are created by adjoining numbers of the form
