Ralph Early Grim
Ralph Early Grim (February 25, 1902 – August 19, 1989) was an American geologist and scientist, often referred to as the "Father of Mineralogy" because he made many discoveries during his investigations of clay materials. He was one of the most outstanding mineralogists of his time and was well-known throughout the world in the field of clay science and technology. Grim's career spanned over 60 years and he received many honors and awards in the field of mineralogy. Some of the textbooks he wrote have been standard university textbooks in mineralogy for many years. Biography Grim was born February 25, 1902, in Reading, Pennsylvania, to parents of Scottish and German descent. His parents were Harry W. Grim, a cigar maker, and Henrietta C. Early, daughter of noted Pennsylvanian Lutheran Minister Rev. John William Early. Before he went to college, Grim had never even been outside of Reading, Pennsylvania where he grew up. He was the first person in his family to attend college a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cigar
A cigar is a rolled bundle of dried and fermented tobacco leaves made to be smoked. Cigars are produced in a variety of sizes and shapes. Since the 20th century, almost all cigars are made of three distinct components: the filler, the binder leaf which holds the filler together, and a wrapper leaf, which is often the highest quality leaf used. Often there will be a cigar band printed with the cigar manufacturer's logo. Modern cigars often come with two bands, especially Cuban cigar bands, showing Limited Edition (''Edición Limitada'') bands displaying the year of production. Cigar tobacco is grown in significant quantities primarily in Central America and the islands of the Caribbean, including Cuba, the Dominican Republic, Haiti, Honduras, Mexico, Ecuador, Nicaragua, Guatemala, Costa Rica, Panama, and Puerto Rico; it is also produced in the Eastern United States, Brazil and in the Mediterranean countries of Italy and Spain (in the Canary Islands), and in Indonesia and the P ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photography
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purp ...

Golf
Golf is a club-and-ball sport in which players use various clubs to hit balls into a series of holes on a course in as few strokes as possible. Golf, unlike most ball games, cannot and does not use a standardized playing area, and coping with the varied terrains encountered on different courses is a key part of the game. Courses typically have either 18 or 9 ''holes'', regions of terrain that each contain a ''cup'', the hole that receives the ball. Each hole on a course contains a teeing ground to start from, and a putting green containing the cup. There are several standard forms of terrain between the tee and the green, such as the fairway, rough (tall grass), and various ''hazards'' such as water, rocks, or sand-filled ''bunkers''. Each hole on a course is unique in its specific layout. Golf is played for the lowest number of strokes by an individual, known as stroke play, or the lowest score on the most individual holes in a complete round by an individual or team, k ...

Emeritus
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Protoc ...

Petrography
Petrography is a branch of petrology that focuses on detailed descriptions of rocks. Someone who studies petrography is called a petrographer. The mineral content and the textural relationships within the rock are described in detail. The classification of rocks is based on the information acquired during the petrographic analysis. Petrographic descriptions start with the field notes at the outcrop and include macroscopic description of hand specimens. The most important petrographer's tool is the petrographic microscope. The detailed analysis of minerals by optical mineralogy in thin section and the micro-texture and structure are critical to understanding the origin of the rock. Electron microprobe or atom probe tomography analysis of individual grains as well as whole rock chemical analysis by atomic absorption, X-ray fluorescence, and laser-induced breakdown spectroscopy are used in a modern petrographic lab. Individual mineral grains from a rock sample may also be analyze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Mississippi
The University of Mississippi (byname Ole Miss) is a public research university that is located adjacent to Oxford, Mississippi, and has a medical center in Jackson. It is Mississippi's oldest public university and its largest by enrollment. The Mississippi Legislature chartered the university on February 24, 1844, and four years later it admitted its first 80 students. During the Civil War, the university operated as a Confederate hospital and narrowly avoided destruction by Ulysses S. Grant's forces. In 1962, during the civil rights movement, a race riot occurred on campus when segregationists tried to prevent the enrollment of African American student James Meredith. The university has since taken measures to improve its image. The university is closely associated with writer William Faulkner, and owns and manages his former Oxford home Rowan Oak, which with other on-campus sites Barnard Observatory and Lyceum–The Circle Historic District, is listed on the National Reg ...

Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...
