Bartholomaeus Pitiscus (also ''Barthélemy'' or ''Bartholomeo''; August 24, 1561 – July 2, 1613) was a 16th-century German trigonometrist, astronomer and theologian who first coined the word ''trigonometry''. Biography Pitiscus was born to poor parents in Grünberg (now Zielona Góra, Poland), then part of the Duchy of Glogau/Głogów, one of the Habsburg-ruled Duchies of Silesia.

Pitiscus (crater)
Pitiscus is a lunar impact crater that lies in the southern part of the Moon's near side, just to the northwest of the larger crater Hommel. It was named after German mathematician Bartholomaeus Pitiscus in 1935. The crater is worn, but still forms a prominent feature upon the surface. The rim is roughly circular, but appears oval from the Earth due to foreshortening. There is an outward bulge to the south-southeast where the interior has slumped. The remainder of the inner wall still displays terraces, although they are worn and rounded due to erosion. The interior floor is level and appears to have been resurfaced by lava. There is a low central peak formation at the midpoint of the interior, and the northern end of this ridge is overlaid by the circular crater Pitiscus A. A slumped and somewhat irregular crater, Pitiscus E, lies along the inner wall to the west-southwest. The interior floor is also marked by several other tiny craters alongside the eastern interior wall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Crater
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, all of which were formed by impacts. The International Astronomical Union currently recognizes 9,137 craters, of which 1,675 have been dated. History The word ''crater'' was adopted from the Greek word for "vessel" (, a Greek vessel used to mix wine and water). Galileo built his first telescope in late 1609, and turned it to the Moon for the first time on November 30, 1609. He discovered that, contrary to general opinion at that time, the Moon was not a perfect sphere, but had both mountains and cup-like depressions. These were named craters by Johann Hieronymus Schröter (1791), extending its previous use with volcanoes. Robert Hooke in ''Micrographia'' (1665) proposed two hypotheses for lunar crater formation: one, that the craters were caused by projectile bombardment from space, the other, that they were the products of subterranean lunar volcanism. Scientific opinion as to the origin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
