Porträt: Christian Goldbach Goldbach wurde in Königsberg als Sohn eines Pfarrers 1690 geboren. Er studierte Jura und beschäftige sich nebenbei mit Mathematik, insbesondere Zahlentheorie. Goldbach war viel auf Reisen (Nordeuropa, Österreich, Italien) und es gelang Ihm dabei immer wertvolle Bekanntschaften zu machen. Es war geschätzter Gesprächs- oder Briefpartner von D.Bernoulli und Euler. Dieser Briefwechsel dauerte fast 20 Jahre und zählt mit fast 200 Briefen zu einem der wichtigsten wissenschafts-geschichtlichen Dokumente im 18.Jahrhundert. Goldbach war seit 1725 erster Konferenzsekretär der gerade gegründeten Petersburger Akademie. Von 1728-1732 weilte er am Hof in Moskau, zeitweise als Erzieher des jungen Prinzen Peter (später Zar Peter II). Ab 1734 war er wieder in Petersburg und ab 1742 nahm er einen Dienst im Auswärtigen Ministerium in Moskau an - war aber fast immer in Petersburg. Von Ihm ist heute noch eine zahlentheoretische Vermutung sehr bekannt, die er am 7.Juni 1742 in einem Brief an Euler erstmals mitteilte (siehe Abbildung). Jede gerade Zahl größer oder gleich 4 ist als Summe zweier Primzahlen darstellbar.

Bunlardan biri de, Goldbach sanýsýnýn bir benzeri olan varsayýmýdýr. Bu varsayým; “5’den büyük her tek sayý üç asal sayýnýn toplamý olarak ifade edilebilir” þeklinde kayýtlara geçmiþtir. Bu varsayým, Golbach’ýn 3 asal problemi olarak bilinir. 3 asal problemi, Goldbach sanýsý kadar önemli olmakla birlikte, onun kadar ünlü deðildir. Bunun sebebi, 3 asal probleminin çýkýþ noktasýnýn Goldbach sanýsý olmasýdýr. Bununla birlikte, 3 asal probleminin çözümüne iliþkin önemli çalýþmalar 20. Yüzyýlýn baþlarýna kadar yapýlmýþ ve çok önemli sonuçlar elde edilmiþtir. 20.yüzyýlýn önemli matematikçilerinden Hardy ve Littlewood, bu konu üzerinde çalýþmýþlar ve 1923 yýlýnda, 3 asal probleminin, yeteri kadar büyük tamsayýlar için, Riemann hipotezi ile örtüþtüðünü göstermiþlerdir. 1937 yýlýnda, Vinogradov, Riemann hipotezine dayanarak, 3 asal probleminin yeteri kadar büyük tek tamsayýlar için doðru olduðunu ispatlamýþtýr.

Back to the Table of Contents Biographies of Mathematicians - Goldbach Christian Goldbach was a famous mathematician. He was born on March 18, 1690 in Konigsberg, Prussia (now Kaliningrad, Russia). He died on November 20, 1764 in Moscow, Russia. So he lived to be 74 and 9/12 and 2 days old. In St. Petersburg he became a professor of mathematics and historian. After that, in 1728, he tutored Tsar Peter II in Moscow. He traveled around Europe and met mathematicians. He was able to meet Leibniz, Nicolaus Bernoulli, Nicolaus(2) Bernoulli, de Moivre, Daniel Bernoulli, and Hermann. Goldbach did much of his work in correspondence with Euler. He did some important mathematical work on number theory. One of his best known works is on his conjecture. Goldbach also did some work with infinite sums, the theory of curves, and the theory of equations. He was born March 18, 1690, died November 20, 1764 Goldbach did much of his work in correspondence with Euler. Goldbach's Conjecture Christian Goldbach's first conjecture is that every even number > 4 is a sum of two primes. It dates from 1742 and it was discovered in correspondence between Goldbach and Euler. A conjecture based on Goldbach's original conjecture is that every odd number > 6 is equal to the sum of three primes. Christian Goldbach's first conjecture is that every even number > 4 is a sum of two primes.

Back to the Table of Contents Christian Goldbach Christian Goldbach was born in Konigsberg, Prussia (now Kaliningrad, Russia) on March 18, 1690. He lived in Russia his entire life and died in Moscow in 1764. In 1725 Goldbach became professor of mathematics and historian at St. Petersburg. Then, in 1728, he went to Moscow as tutor to Tsar Peter II. He traveled around Europe meeting mathematicians. Goldbach did important work in number theory. A lot of it corresponded with Euler. He is remembered best for his conjecture, made in 1742 in a letter to Euler and still an open question, that every even integer greater than 2 can be represented as the sum of two primes. Goldbach also conjectured that every odd number is the sum of three primes. Goldbach also studied infinite sums, the theory of curves and the theory of equations. Goldbach's Conjecture His famous conjecture was made in 1742 and for 255 years, no one has succeeded in proving or disproving the correctness of this conjecture. It is thought that Goldbach's Conjecture will be settled before 12/31/2020. If it becomes "settled", this means it will be either proven, refuted, or proven undecidable.

34. Goldbach, Christian Friedrich. Neuster Himmels-Atlas . Weimar, 1799. Goldbach's star atlas is a fairly exact copy of the Bode Flamsteed edition of 1782, with two striking differences. The most obvious is that Goldbach's star maps are white on a black background. The second modification is that a matching plate is provided on the facing page with the constellation figures omitted. The image shown here is a detail of the plate of Andromeda; to see the entire plate, and the matching plate without the constellation outline, click here. What is particularly interesting about the Goldbach atlas is the method of printing. Normally, white on black images are printed on woodblocks; the Semler atlas of 1731 used such a technique. Goldbach's images however were engraved on copper plates, which were then printed in relief (with the ink on the surface) rather than in intaglio (with the ink down in the engraved lines and the surface wiped clean).

(An alternative way of expressing this is that every even integer greater than 4 can be expressed as the sum of two odd primes). To give Euler some credit, in fact in his letter Goldbach expressed the belief that "Every integer n > 5 is the sum of three primes". It was Euler who pointed out that this is easily seen to be equivalent to the statement that "Every even integer is the sum of two primes", the standard description of "Goldbach's Conjecture".

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! Today, prime numbers are fascinating but they are also of commercial importance, since the best commercial and military ciphers depend on their properties. (See " Discovering new primes " in Issue 1 - it is yet to be proved that there are infinitely many Mersenne primes.)
