The standard versions of Archimedes' life were written long after his death by Greek and Roman historians. From his surviving written works, it is clear that he maintained collegiate relations with scholars based there, including his friend Conon of Samos and the head librarian Eratosthenes of Cyrene. It is unknown, for instance, whether he ever married or had children, or if he ever visited Alexandria, Egypt, during his youth. A biography of Archimedes was written by his friend Heracleides, but this work has been lost, leaving the details of his life obscure. In the Sand-Reckoner, Archimedes gives his father's name as Phidias, an astronomer about whom nothing else is known. The date of birth is based on a statement by the Byzantine Greek historian John Tzetzes that Archimedes lived for 75 years before his death in 212 BC. Biography Cicero Discovering the Tomb of Archimedes (1805) by Benjamin WestĪrchimedes was born c. 287 BC in the seaport city of Syracuse, Sicily, at that time a self-governing colony in Magna Graecia. 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 and again in the 17th century, while the discovery in 1906 of previously lost works by Archimedes in the Archimedes Palimpsest has provided new insights into how he obtained mathematical results. 530 AD by Isidore of Miletus in Byzantine Constantinople, while commentaries on the works of Archimedes by Eutocius in the 6th century opened them to wider readership for the first time. Mathematicians from Alexandria read and quoted him, but the first comprehensive compilation was not made until c. Unlike his inventions, Archimedes' mathematical writings were little known in antiquity. Cicero describes visiting Archimedes' tomb, which was surmounted by a sphere and a cylinder that Archimedes requested be placed there to represent his mathematical discoveries.
He is also credited with designing innovative machines, such as his screw pump, compound pulleys, and defensive war machines to protect his native Syracuse from invasion.Īrchimedes died during the siege of Syracuse, when he was killed by a Roman soldier despite orders that he should not be harmed. Archimedes' achievements in this area include a proof of the law of the lever, the widespread use of the concept of center of gravity, and the enunciation of the law of buoyancy or Archimedes' principle. He was also one of the first to apply mathematics to physical phenomena, working on statics and hydrostatics. Īrchimedes' other mathematical achievements include deriving an approximation of pi, defining and investigating the Archimedean spiral, and devising a system using exponentiation for expressing very large numbers. These include the area of a circle, the surface area and volume of a sphere, the area of an ellipse, the area under a parabola, the volume of a segment of a paraboloid of revolution, the volume of a segment of a hyperboloid of revolution, and the area of a spiral. Considered the greatest mathematician of ancient history, and one of the greatest of all time, Archimedes anticipated modern calculus and analysis by applying the concept of the infinitely small and the method of exhaustion to derive and rigorously prove a range of geometrical theorems. Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity. 212 BC) was an Ancient Greek mathematician, physicist, engineer, astronomer, and inventor from the ancient city of Syracuse in Sicily.

But I’d trade the cracked toenails and numb pinkie toes for Mises any day.Archimedes of Syracuse ( / ˌ ɑːr k ɪ ˈ m iː d iː z/, ARK-ihm- EE-deez c. I do miss the look-and stomp-of my old kitchen boots.
The look isn’t for everyone, but they fit a utili- tarian, ugly-cool niche. And the cushioning lives between firm and foamy, providing all-day support, while the tread is grippy enough to withstand whatever mystery liquid has pooled by the sink. The sole isn’t lofty as with some clogs, which I’ve found to be a surefire recipe for rolled ankles. Their flexible leather upper gives way to a breathable, perforated neoprene opening that hugs your ankle. The four pairs of shoes I’ve tried all let me down, but I found the cure during a post-shift Instagram scroll: Mise’s superbly comfortable slip-on kitchen shoes. I’ve lost as many toenails from a few years of my feet jamming against the front of my kitchen boots as I have in 17 years as a runner.
Now, I’m a line cook who stands 50 to 60 hours a week. Until a few years ago, I worked as a writer, my unfettered civilian feet tucked into whatever I pleased.
