Archimedes of Syracuse (Greek: Ἀρχιμήδης; c. 287 BC c. 212 BC) was a Greek mathematician, physicist, engineer, inventor, and astronomer. Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity. Among his advances in physics are the foundations of hydrostatics, statics and the explanation of the principle of the lever. He is credited with designing innovative machines, including siege engines and the screw pump that bears his name. Modern experiments have tested claims that Archimedes designed machines capable of lifting attacking ships out of the water and setting ships on fire using an array of mirrors.[1]
Archimedes is generally considered to be the greatest mathematician of antiquity and one of the greatest of all time.[2][3] He used the method of exhaustion to calculate the area under the arc of a parabola with the summation of an infinite series, and gave a remarkably accurate approximation of pi.[4] He also defined the spiral bearing his name, formulas for the volumes of surfaces of revolution and an ingenious system for expressing very large numbers.
Archimedes died during the Siege of Syracuse when he was killed by a Roman soldier despite orders that he should not be harmed. Cicero describes visiting the tomb of Archimedes, which was surmounted by a sphere inscribed within a cylinder. Archimedes had proven that the sphere has two thirds of the volume and surface area of the cylinder (including the bases of the latter), and regarded this as the greatest of his mathematical achievements.
Unlike his inventions, the mathematical writings of Archimedes were little known in antiquity. Mathematicians from Alexandria read and quoted him, but the first comprehensive compilation was not made until c. 530 AD by Isidore of Miletus, while commentaries on the works of Archimedes written by Eutocius in the sixth century AD opened them to wider readership for the first time. The relatively few copies of Archimedes' written work that survived through the Middle Ages were an influential source of ideas for scientists during the Renaissance,[5] while the discovery in 1906 of previously unknown works by Archimedes in the Archimedes Palimpsest has provided new insights into how he obtained mathematical results.[6]

@nikolaos1010 Δεν μας χέζεις ρε Νταράλα ψωνάρα. Νewton by himself said that "I did great job, cause i could step on Giant's (Archimedes) shoulder ". We cant compare a Mathematician who found this science , with a developer. Remind me, the word of Maths in Newton's language please ?

@BraveManNewWorld2 Ο Όμηρος ...την γην την Γραικήν καλουμένην, ην νέμονται Ωρώπιοι Αθηναίων, υπήκοοι, εδήωσαν. Ο Αλκμάν ονόμαζε Γραίκες τις μητέρες των Ελλήνων. Απολλόδωρος λέει ότι Γραικοί λέγονταν οι πρώτοι Έλληνες.Αριστοτέλης “Μετεωρολογικά” κατοικούσαν οι Σέλλοι (γνωστοί και από τα Ομηρικά έπη) και αυτοί που τώρα ονομάζονται Έλληνες (στην εποχή του Αριστοτέλη), οι Γραικοί. Ιστορία μιλάω, όχι μυθολογία. Όλες είναι σωστές είναι ονομασίες. Κόμπλεξ έχουν αυτοί που δεν έχουν ιστορία, όχι εμείς

@tektamos .. Όσο αφορά την Μυθολογία δεν ονόμαζαν τους Έλληνες Γραικούς.... ένα άτομο ήταν ο Γραικός. Το όνομα Γραικός το πήραν οι Έλληνες όπως σου έχω αναφέρει... Greek = Grekos που ΝΑΙ σημαίνει Έλληνας, αλλά η πραγματική και σωστή ονομασία ειναι Ηellinis, Hellas που σημαίνει ακριβώς την έννοια του Έλληνα και της Ελλάδας

@tektamos ... Που λέει ρε φίλε, ο Αριστοτέλης τήν λέξη Γραικός; Δώσε τίτλο και χωριό.

@BraveManNewWorld2 Αre you dreaming ? Is exactly the same or you are not Greek ? Becasue if you are not Greek , you shouldn't do a question like that. Γραικός λεει ο Αριστοτέλης , Γραικός γεννήθηκα γραικός θε να πεθάνω και ο Διακος. Γραικός ο υιός Διός , Έλληνας Υιός Δευκαλίωνα.

@tektamos .. meaning is not the same, the rest of the word think that is the same. For greek language and history is not

@reflexionofme Βοth words are same. Its like we call Germans the Germans, but they calling themselves Deutsche and Deutscheland. The Greeks calling themselves Hellenes but specialy the midle ages others Eyropeans used more the word Greek than Hellas. But the first time the Greek states cities became one from Pella to Knossos, from Sparta to Athens, from Syracuse to Cyprus, they preferesd be called Hellenes, because Hellenas was the son of Dephkalion the first man "made" by Zeus
