Boole (crater)
Boole is a lunar impact crater that lies along the northwestern limb of the Moon, to the northwest of the crater Gerard. At this location it is viewed nearly from the side, and is very oblong in shape due to foreshortening. The crater formation is nearly circular, however, with a wide inner wall that has been worn and rounded due to subsequent impacts. It is named after George Boole. To the north of Boole is the crater Cremona Cremona (, also ; ; lmo, label= Cremunés, Cremùna; egl, Carmona) is a city and ''comune'' in northern Italy, situated in Lombardy, on the left bank of the Po river in the middle of the ''Pianura Padana'' ( Po Valley). It is the capital of th ..., and to the southwest are Paneth and Smoluchowski. The eroded and somewhat distorted satellite crater Boole E is attached to the southern rim, forming a saddle-shaped valley between the two formations. The interior floor of Boole is relatively flat, and marked only by tiny craterlets. There is a small crater ...

Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. Its detailed mapping program is identifying safe landing sites, locating potential resources on the Moon, characterizing the radiation environment, and demonstrating new technologies. Launched on June 18, 2009, in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, LRO was the first United States mission to the Moon in over ten years. LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program. The probe has made a 3-D map of the Moon's surface at 100-meter resolution and 98.2% coverage (excluding polar areas in deep shadow), including 0.5-meter resolution images of Apollo landing sites. The first images f ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

George Boole
George Boole (; 2 November 1815 – 8 December 1864) was a largely self-taught English mathematician, philosopher, and logician, most of whose short career was spent as the first professor of mathematics at Queen's College, Cork in Ireland. He worked in the fields of differential equations and algebraic logic, and is best known as the author of ''The Laws of Thought'' (1854) which contains Boolean algebra. Boolean logic is credited with laying the foundations for the Information Age. Early life Boole was born in 1815 in Lincoln, Lincolnshire, England, the son of John Boole senior (1779–1848), a shoemaker and Mary Ann Joyce. He had a primary school education, and received lessons from his father, but due to a serious decline in business, he had little further formal and academic teaching. William Brooke, a bookseller in Lincoln, may have helped him with Latin, which he may also have learned at the school of Thomas Bainbridge. He was self-taught in modern languages.H ...

Lunar Craters
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]   |

Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gerard (crater)
Gerard is a lunar impact crater that lies along the western edge of the Oceanus Procellarum near the northwest limb of the Moon's near side. It is located to the north-northwest of the crater von Braun, and northeast of Bunsen. Because of its location, Gerard appears strongly foreshortened when viewed from the Earth, hindering observation. This is a worn and eroded formation with a rim that has been nearly obliterated in some locations and distorted in others. The northern half of the rim has outward bulges to the northeast, north, and northwest. The interior floor is rough in places, with several small and tiny craters along the floor and the eastern rim. To the northwest of this formation is the unusual Gerard Q Inner (eastern floor covered in dark- hued basaltic lava Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cremona (crater)
Cremona is a lunar impact crater that is located along the north-northwestern limb of the Moon. From the Earth this crater is viewed from the side, and the visibility is affected by libration effects. To be viewed in any detail, this crater must be seen or photographed from orbit. It is located midway between the crater Boole to the south-southeast and, on the far side ''The Far Side'' is a single-panel comic created by Gary Larson and syndicated by Chronicle Features and then Universal Press Syndicate, which ran from December 31, 1979, to January 1, 1995 (when Larson retired as a cartoonist).

Paneth (crater)
Paneth is a lunar impact crater that is located on the far side of the Moon, just beyond the northwestern limb. It lies just to the north-northeast of the crater Smoluchowski, and to the east-southeast of Boole George Boole (; 2 November 1815 – 8 December 1864) was a largely self-taught English mathematician, philosopher, and logician, most of whose short career was spent as the first professor of mathematics at Queen's College, Cork in Irel ... on the near side. The rim of Paneth is worn, but only moderately; the edge remains well-defined and marked only by small craters along the northwest and southeast. This formation partly overlies a shallower crater Paneth K along the southeast of the rim. Only a narrow strip of terrain separates Paneth from Smoluchowski, and this ground is marked by an elongated crater and a short rille. The interior floor has a central peak formation near the midpoint and a pair of small craters along the eastern rim. The inner surface i ...

Smoluchowski (crater)
Smoluchowski is a lunar impact crater on the far side of the Moon. It lies in the part of the lunar surface that is sometimes brought into view of the Earth during periods of favorable libration In lunar astronomy, libration is the wagging or wavering of the Moon perceived by Earth-bound observers and caused by changes in their perspective. It permits an observer to see slightly different hemispheres of the surface at different tim ... and illumination from sunlight, but at such times little detail can be seen as the crater is observed from the edge. Smoluchowski lies across the northern rim of the larger walled plain Poczobutt. Nearly attached to the north-northeastern outer rim of Smoluchowski is the smaller crater Paneth. This is a worn and eroded crater formation that has still managed to retain much of its original shape. The remains of a small crater lie across the southern floor and inner wall of Smoluchowski, protruding outwards slightly into Poczobutt. A smaller ...

Brianchon (crater)
Brianchon is a Lunar craters, lunar impact crater that is located along the northwestern limb of the Moon. Due to its location, from the Earth the crater is seen from the edge and its visibility is somewhat affected by libration. Thus for a more detailed view, the crater must be viewed from orbit. This crater lies just to the west of the crater Pascal (crater), Pascal, and Desargues (crater), Desargues is to the southeast. To the south of Brianchon along the limb is the crater Cremona (crater), Cremona, while Lindblad (crater), Lindblad lies to the southwest just on the Far side (Moon), far side of the Moon. Brianchon has been worn and eroded by a history of impacts that followed its creation. The most prominent of these are a pair of craters that lie across the northern rim, and Brianchon B which intrudes slightly into the southern rim. Brianchon A forms an outward bulge in the rim to the northwest, but otherwise merges seamlessly into the crater formation. There is also a conce ...
