The Hellenic Navy (HN) (Greek: Πολεμικό Ναυτικό, Polemikó Naftikó, abbreviated ΠΝ) is the naval force of Greece, part of the Greek Armed Forces. The modern Greek navy has its roots in the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy (1833–1924 and 1936–1973) it was known as the Royal Navy (Βασιλικόν Ναυτικόν, Vasilikón Naftikón, abbreviated ΒΝ).The total displacement of all the navy's vessels is approximately 150,000 tons.The motto of the Hellenic Navy is "Μέγα το της Θαλάσσης Κράτος" from Thucydides' account of Pericles' oration on the eve of the Peloponnesian War. This has been roughly translated as "Great is the country that controls the sea". The Hellenic Navy's emblem consists of an anchor in front of a crossed Christian cross and trident, with the cross symbolizing Greek Orthodoxy, and the trident symbolizing Poseidon, the god of the sea in Greek mythology. Pericles' words are written across the top of the emblem. "The navy, as it represents a necessary weapon for Greece, should only be created for war and aim to victory."...............The Hellenic Merchant Marine refers to the Merchant Marine of Greece, engaged in commerce and transportation of goods and services universally. It consists of the merchant vessels owned by Greek civilians, flying either the Greek flag or a flag of convenience. Greece is a maritime nation by tradition, as shipping is arguably the oldest form of occupation of the Greeks and a key element of Greek economic activity since the ancient times. Nowadays, Greece has the largest merchant fleet in the world, which is the second largest contributor to the national economy after tourism and forms the backbone of world shipping. The Greek fleet flies a variety of flags, however some Greek shipowners gradually return to Greece following the changes to the legislative framework governing their operations and the improvement of infrastructure.

World's cleverest man....[ 790 ]

World's cleverest man turns down $1million prize after solving one of mathematics' greatest puzzles

No need for greed: A rare photo of bearded and reclusive genius Dr Grigory Perelman

A Russian awarded $1million (£666,000) for solving one of the most intractable problems in mathematics said yesterday that he does not want the money.

Said to be the world's cleverest man, Dr Grigory Perelman, 44, lives as a recluse in a bare cockroach-infested flat in St Petersburg. He said through the closed door: 'I have all I want.'

The prize was given by the U.S. Clay Mathematics Institute for solving the Poincare Conjecture, which baffled mathematicians for a century. Dr Perelman posted his solution on the internet.

Four years ago, the maths genius failed to turn up to receive his prestigious Fields Medal from the International Mathematical Union for solving the problem.

At the time he stated: 'I'm not interested in money or fame. I don't want to be on display like an animal in a zoo.

'I'm not a hero of mathematics. I'm not even that successful, that is why I don't want to have everybody looking at me.'

Neighbour Vera Petrovna said: 'I was once in his flat and I was astounded. He only has a table, a stool and a bed with a dirty mattress which was left by previous owners - alcoholics who sold the flat to him.

'We are trying to get rid of cockroaches in our block, but they hide in his flat.'

It was in 2002 that Perelman, then a researcher at the Steklov Institute of Mathematics in St. Petersburg, began posting papers online suggesting he had solved the Poincare Conjecture, one of seven major mathematical puzzles for which the Clay Institute is offering $1 million each.

Rigorous tests proved he was correct.

The topological conundrum essentially states that any three-dimensional space without holes in it is equivalent to a stretched sphere.

The puzzle was more than 100 years old when Perelman solved it - and could help determine the shape of the universe.

After 2003 Perelman gave up his job at the Steklov Institute. Friends have been reported as saying he has resigned from mathematics altogether - finding the subject too painful to discuss.
