John Hazzidakis
Ioannis "John" N. Hazzidakis (Ιωάννης Χατζιδάκις, or ''Hatzidakis'' or ''Chatzidakis'', April 13, 1844 – 1921) was a Greek mathematician, physicist, author, and professor. He is one of the most important mathematicians of the modern Greek scientific era. His professor was world renowned Greek mathematician Vassilios Lakon. He also studied with famous German mathematicians Ernst Kummer, Leopold Kronecker, Karl Weierstrass. He systematically worked in the field of research and education. He wrote textbooks in the field of algebra, geometry, and calculus. Hazzidakis essentially adopted some elements of Lacon's Geometry. He introduced the Hazzidakis transform in differential geometry. The Hazzidakis formula for the Hazzidakis transform can be applied in proving Hilbert's theorem on negative curvature, stating that hyperbolic geometry does not have a model in 3-dimensional Euclidean space. Biography He was born in Crete in 1844. He completed his basic edu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rethymno
Rethymno ( el, Ρέθυμνο, , also ''Rethimno'', ''Rethymnon'', ''Réthymnon'', and ''Rhíthymnos'') is a city in Greece on the island of Crete.

History This region as a whole is rich with ancient history, most notably through the Minoan civilisation centred at Knossos east of Rethymno. Rethymno itself began a period of growth when the Venetian conquerors of the island decided to put an intermediate commercial station between Heraklion and Chania, acquiring its own bishop and nobility in the ...

People From Rethymno (regional Unit)
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Academic Staff Of The National Technical University Of Athens
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

19th-century Greek Mathematicians
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under Colonialism, colonial rule. It was also marked by the collapse o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

National Technical University Of Athens
The National (Metsovian) Technical University of Athens (NTUA; el, Εθνικό Μετσόβιο Πολυτεχνείο, ''National Metsovian Polytechnic''), sometimes known as Athens Polytechnic, is among the oldest higher education institutions of Greece and the most prestigious among engineering schools. It is named in honor of its benefactors Nikolaos Stournaris, Eleni Tositsa, Michail Tositsas and Georgios Averoff, whose origin is from the town of Metsovo in Epirus. It was founded in 1837 as a part-time vocational school named Royal School of Arts which, as its role in the technical development of the fledgling state grew, developed into Greece's sole institution providing engineering degrees up until the 1950s, when polytechnics were established outside Athens. Its traditional campus, located in the center of Athens on Patission Avenue on a site donated by Eleni Tositsa, features a suite of magnificent neo- classical buildings by architect Lysandros Kaftantzoglou (1811–1 ...
