Detail from Santbech's Problematum astronomicorum et geometricorum

Daniel Santbech (fl. 1561) was a Dutch mathematician and astronomer. He adopted the Latin name of Noviomagus. This Latinized name may suggest that he came from the town of Nijmegen, called Ulpia Noviomagus Batavorum by the Romans. // Events The Edict of Orleans suspends the persecution of the Huguenots. ...

Nijmegen (Zuid-Gelders: Nèhméége) (obsolete spellings: Nijmwegen, Nymegen, Nieumeghen — known in German as Nimwegen, French as Nimègue, and Spanish as Nimega) is a municipality and a city in the east of the Netherlands, near the German border. ... The Roman Forum was the central area around which ancient Rome developed. ...

In 1561, Santbech compiled a collected edition of Regiomontanus' De triangulis planis et sphaericis libri quinque (first published in 1533) and Compositio tabularum sinum recto, as well as Santbech's own Problematum astronomicorum et geometricorum sectiones septem. It was published in Basel (Henrich Petri and Petrus Perna). // Events The Edict of Orleans suspends the persecution of the Huguenots. ...

Santbech's work comprised of studies on astronomy, sundials, surveying, and levelling for water courses. It also includes descriptions of astronomical instruments, information for navigators and geographers, and general information about astronomy in the first years after Copernicus. Astronomy (Greek: αστρονομία = άστρον + νόμος, astronomia = astron + nomos, literally, law of the stars) is the science of celestial objects and phenomena that originate outside the Earths atmosphere, such as stars, planets, comets, aurora, galaxies, and the cosmic background radiation. ...

Its main purpose is the discipling (training) of Christians with a particular emphasis on enabling them to share their faith with others. ... A geographer is a scientist whose area of study is geography, the study of the physical environment and human habitat. ... Nicolaus Copernicus (in Latin; Polish Mikołaj Kopernik, German Nikolaus Kopernikus - February 19, 1473 – May 24, 1543) was a Polish astronomer, mathematician and economist who developed a heliocentric (Sun-centered) theory of the solar system in a form detailed enough to make it scientifically useful. ...

Santbech also studied the subject of gunnery and ballistics as a theoretic discourse as well as for the practical application of war, and utilized the foundations of geometry, with ample references to Euclid and Ptolemy, in order to do so. Santbech seem not to have been aware of similar studies by Niccolò Fontana Tartaglia.[1] 155 mm M198 howitzer U.S. Army soldier with a compact M249 variant USS Iowa (BB-61) fires a full broadside of nine 16/50 and six 5/38 guns during a target exercise near Vieques Island, Puerto Rico, 1 July 1984. ...

Santbech's text included theoretical illustrations of trajectories. These were depicted with abruptly acute angles and straight lines, allowing him to create a right-angled triangle from which ranges were computed with the help of a table of sines. Santbech was of course fully aware that a cannonball's true trajectory would not consist of a straight line and a sudden drop, but these depictions were meant to assist with mathematical calculations. A trajectory is an imagined trace of positions followed by an object moving through space. ... Acute may refer to: An acute accent is a diacritic character. ... In mathematics, the range of a function is the set of all output values produced by that function. ... In mathematics, the trigonometric functions are functions of an angle, important when studying triangles and modeling periodic phenomena. ...
