The Jesuit priest, mathematician and astronomer Christoph Scheiner was born on 25 July 1575 in Wald near Mindelheim (Swabia). He attended the Jesuit grammar school in Landsberg am Lech and in Augsburg.
From 1598 to 1601 Scheiner studied metaphysics and mathematics in Ingolstadt - my homework . In 1603, at the suggestion of a painter, he developed the pantograph (stork's bill), a device for transferring an original to scale.
From 1610 to 1617 Christoph Scheiner was professor of mathematics and Hebrew in Ingolstadt. He lectured on practical geometry, astronomy and optics. In 1623 he became rector of the Jesuit College in Neisse (Silesia).
In 1631 Scheiner published his findings on the construction - do my math homework for me - and use of a pantograph under the title "Pantographice seu ars delineandi". From 1624 to 1637 he stayed in Vienna and in Rome. On 18 July 1650 he died in Neisse as a result of a stroke.
Independently of Galileo Galilei - homework help geometry , Scheiner discovered sunspots and calculated the rotation period of the sun with a self-built telescope in the tower room of the Holy Cross Church in Ingolstadt in 1611. He produced the first maps of the moon in 1614 and described sunspots and the development of telescopes in his main work "Rosa Ursina sive Sol", which was published between 1626 and 1630. He also made numerous discoveries on the physiological optics of the eye.
