Uncle Petros And Goldbach's Conjecture
''Uncle Petros and Goldbach's Conjecture'' is a 1992 novel by Greek author Apostolos Doxiadis. It concerns a young man's interaction with his reclusive uncle, who sought to prove a famous unsolved mathematics problem, called Goldbach's Conjecture, that every even number greater than two is the sum of two primes. The novel discusses mathematical problems and some recent history of mathematics. Plot Petros Papachristos, a child prodigy, is brought by his father, a Greek businessman, to the University of Munich to verify his genius with Constantin Caratheodory, a Greek-German mathematician. The boy immediately shows an excellent aptitude for mathematics and graduates soon at the University of Berlin. Later he worked as a postdoctoral researcher at the University of Cambridge, where he collaborates with the mathematicians Godfrey Harold Hardy, John Edensor Littlewood and Srinivasa Ramanujan. He is then offered a professorship in Munich, which he accepts because it was far from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apostolos Doxiadis
Apostolos K. Doxiadis ( el, Απόστολος Κ. Δοξιάδης; born 1953) is a Greek writer. He is best known for his international bestsellers ''Uncle Petros and Goldbach's Conjecture'' (2000) and ''Logicomix'' (2009). Early life Doxiadis was born in Australia, where his father, the architect Constantinos Apostolou Doxiadis was working. Soon after his birth, the family returned to Athens, where Doxiadis grew up. Though his earliest interests were in poetry, fiction and the theatre, an intense interest in mathematics led Doxiadis to leave school at age fifteen, to attend Columbia University, in New York, from which he obtained a bachelor's degree in mathematics. He then attended the École Pratique des Hautes Études in Paris from which he got a master's degree, with a thesis on the mathematical modelling of the nervous system. His father's death and family reasons made him return to Greece in 1975, interrupting his graduate studies. In Greece, although involved for some ye ...

Goldbach's Conjecture
Goldbach's conjecture is one of the oldest and best-known unsolved problems in number theory and all of mathematics. It states that every even natural number greater than 2 is the sum of two prime numbers. The conjecture has been shown to hold for all integers less than 4 × 1018, but remains unproven despite considerable effort. History On 7 June 1742, the German mathematician Christian Goldbach wrote a letter to Leonhard Euler (letter XLIII), in which he proposed the following conjecture: Goldbach was following the now-abandoned convention of considering 1 to be a prime number, so that a sum of units would indeed be a sum of primes. He then proposed a second conjecture in the margin of his letter, which implies the first: Euler replied in a letter dated 30 June 1742 and reminded Goldbach of an earlier conversation they had had (), in which Goldbach had remarked that the first of those two conjectures would follow from the statement This is in fact equivalent to ...

I Saw The Figure 5 In Gold
''I Saw the Figure 5 in Gold,'' also known as ''The Figure 5 in Gold'', is a 1928 painting by American artist Charles Demuth. It has been described as influenced by Futurism and Cubism. Inspiration William Carlos Williams claims that the inspiration for the 32-word poem "The Great Figure" (1920) came from seeing a fire engine pass him by, sounding gong clangs and siren howls as it receded in the night. He said he was so struck by the sight that he took paper and pencil out of his pocket and wrote the poem, standing there on the sidewalk. Two lines: "I saw the figure 5/in gold" were taken by Demuth for his painting's title. The upper right corner has an arc, implying a fragment of a large number five, repeated three times in progressively smaller, complete number fives to create an impression of the fire engine moving away from the viewer. The fire engine itself is reduced to an abstracted form composed of red rectangles, but there is a hint of a ladder on the right side and an axle ...

The Fox And The Grapes
The Fox and the Grapes is one of Aesop's fables, numbered 15 in the Perry Index. The narration is concise and subsequent retellings have often been equally so. The story concerns a fox that tries to eat grapes from a vine but cannot reach them. Rather than admit defeat, he states they are undesirable. The expression "sour grapes" originated from this fable. The fable The fable of The Fox and the Grapes is one of the few which feature only a single animal protagonist. There are several Greek versions as well as one in Latin by Phaedrus (IV.3) which is terse and to the point: In her version of La Fontaine's Fables, Marianne Moore underlines his ironic comment on the situation in a final pun, "Better, I think, than an embittered whine". Although the fable describes purely subjective behaviour, the English idiom "sour grapes", which derives from the story, is now often used also of envious disparagement of something to others. Similar expressions exist in other languages of Eu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aesop
Aesop ( or ; , ; c. 620–564 BCE) was a Greek fabulist and storyteller credited with a number of fables now collectively known as ''Aesop's Fables''. Although his existence remains unclear and no writings by him survive, numerous tales credited to him were gathered across the centuries and in many languages in a storytelling tradition that continues to this day. Many of the tales associated with him are characterized by anthropomorphic animal characters. Scattered details of Aesop's life can be found in ancient sources, including Aristotle, Herodotus, and Plutarch. An ancient literary work called ''The Aesop Romance'' tells an episodic, probably highly fictional version of his life, including the traditional description of him as a strikingly ugly slave () who by his cleverness acquires freedom and becomes an adviser to kings and city-states. Older spellings of his name have included ''Esop(e)'' and ''Isope''. Depictions of Aesop in popular culture over the last 2,500 yea ...

Athens
Athens ( ; el, Αθήνα, Athína ; grc, Ἀθῆναι, Athênai (pl.) ) is both the capital and largest city of Greece. With a population close to four million, it is also the seventh largest city in the European Union. Athens dominates and is the capital of the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years and its earliest human presence beginning somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state. It was a centre for the arts, learning and philosophy, and the home of Plato's Academy and Aristotle's Lyceum. It is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political influence on the European continent—particularly Ancient Rome. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Gre ...

Ekali
Ekali ( el, Εκάλη) is an affluent suburb of Athens, Greece. Located to the north of the city centre, it is a green and lush area home to many of the country's most powerful business and shipping families. Since the 2011 local government reform it is part of the municipality of Kifisia, as a municipal unit. Etymology Ekali was an ancient municipality of Athens and belonged to the Leontida tribe. Its inhabitants were named Ekalios. According to tradition, the name is associated with the name of a woman named Ekali. As Plutarch says, as Theseus went to Marathon to catch the famous bull that had caused great damage to the area, the weather conditions were unfavorable. The Athenian king sought refuge in the hut of an old woman, called Ekali. The old woman promised Theseus that she would make a sacrifice to Zeus for the success of his mission. When Theseus caught the bull, he returned to the hut, but found the old woman dead. Grateful for her sacrifice, he later created the sanct ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide. Chess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, t ...

Kurt Gödel
Kurt Friedrich Gödel ( , ; April 28, 1906 – January 14, 1978) was a logician, mathematician, and philosopher. Considered along with Aristotle and Gottlob Frege to be one of the most significant logicians in history, Gödel had an immense effect upon scientific and philosophical thinking in the 20th century, a time when others such as Bertrand Russell,For instance, in their "Principia Mathematica' (''Stanford Encyclopedia of Philosophy'' edition). Alfred North Whitehead, and David Hilbert were using logic and set theory to investigate the foundations of mathematics, building on earlier work by the likes of Richard Dedekind, Georg Cantor and Frege. Gödel published his first incompleteness theorem in 1931 when he was 25 years old, one year after finishing his doctorate at the University of Vienna. The first incompleteness theorem states that for any ω-consistent recursive axiomatic system powerful enough to describe the arithmetic of the natural numbers (for example P ...
