Archimedes Screw Design Parameters
Archimedes of Syracuse ( ; ) was an Ancient Greek mathematician, physicist, engineer, astronomer, and inventor from the ancient city of Syracuse in Sicily. Although few details of his life are known, based on his surviving work, he is considered one of the leading scientists in classical antiquity, and one of the greatest mathematicians of all time. Archimedes anticipated modern calculus and analysis by applying the concept of the infinitesimals and the method of exhaustion to derive and rigorously prove many geometrical theorems, including 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. Archimedes' other mathematical achievements include deriving an approximation of pi (), defining and investigating the Archimedean spiral, and devising a system using exponentiation for ex ...

Domenico Fetti
Domenico Fetti (also spelled Feti) ( – 16 April 1623) was an Italian Baroque painter who was active mainly in Rome, Mantua and Venice. Biography Born in Rome to a little-known painter, Pietro Fetti, Domenico is said to have apprenticed initially under Ludovico Cigoli, or his pupil Andrea Commodi in Rome from circa 1604–1613. He then worked in Mantua from 1613 to 1622, patronized by the Cardinal, later Duke Ferdinando I Gonzaga. In the Ducal Palace, he painted the ''Miracle of the Loaves and Fishes''. The series of representations of New Testament parables he carried out for his patron's '' studiolo'' gave rise to a popular speciality, and he and his studio often repeated his compositions. In August or September 1622, his feuds with some prominent Mantuans led him to move to Venice, which for the first few decades of the seventeenth century had persisted in sponsoring Mannerist styles (epitomized by Palma the Younger and the successors of Tintoretto and Veronese).
