Barbicane, consulting his map, recognized Eratosthenes.
Soon Eratosthenes disappeared under the horizon without the projectile being sufficiently near to allow close observation.
In maths, the Sieve of
Eratosthenes is used to calculate what?
According to a press release from the Foundation for Research and Innovation, the Foundation and the directorate-general for European Coordination and Development Programmes as the national bodies responsible for the participation of Cyprus in the Horizon 2020 programme, announced the selection of the
Eratosthenes: Excellence Research Centre for Earth Surveillance and Space-Based Monitoring of the Environment (Excelsior), coordinated by the Cyprus University of Technology (Tepak).
Notes: Named for 3rd-century BCE Greek mathematician and philosopher
Eratosthenes, first scholar to calculate the circumference of the Earth.
Around 240 B.C.,
Eratosthenes estimated the diameter of the earth to within less than a percentage point of the currently accepted value.
Other mare craters, such as Lansberg,
Eratosthenes, and Archimedes, formed earlier than the last lava flows that covered their ejecta.
"An ancient scholar named
Eratosthenes the head of the famous library of Alexandria in Egypt even correctly approximated the circumference of the Earth using experimental measurements of shadows in two cities and some geometry.
He discussed Simmias the elephant hunter and other people at the court of Ptolemy; kingship, symposia, gift-exchange: parameters of friendship; an entertaining genre; technology and performance in
Eratosthenes and Andreas; and Herophilus' pulse and Archimedes' mechanized mathematics.
It has attracted many of the most outstanding mathematicians in history including Euclid, Diophantus, Fermat, Legendre, Euler, Gauss, Dedekind, Jacobi, Eisenstein, Sieve of
Eratosthenes and Hilbert all made immense contribution to its development.
