Nicholas Mayall
Nicholas Ulrich Mayall (May 9, 1906 – January 5, 1993) was an American observational astronomer. After obtaining his doctorate from the University of California, Berkeley, Mayall worked at the Lick Observatory, where he remained from 1934 to 1960, except for a brief period at MIT's Radiation Laboratory during World War II. During his time at Lick, Mayall contributed to astronomical knowledge of nebulae, supernovae, spiral galaxy internal motions, the redshifts of galaxies, and the origin, age, and size of the Universe. He played a significant role in the planning and construction of Lick's reflector, which represented a major improvement over its earlier telescope. From 1960, Mayall spent 11 years as director of the Kitt Peak National Observatory until his retirement in 1971. Under his leadership KPNO, and the Cerro Tololo Inter-American Observatory, developed into two of the world's top research observatories, equipped with premier telescopes. Mayall was responsible f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bolo Tie
A bolo tie (sometimes bola tie or shoestring necktie) is a type of necktie consisting of a piece of cord or braided leather with decorative metal tips (called aiguillettes) and secured with an ornamental clasp or slide. Popularity In the United States, bolo ties are widely associated with Western wear and are generally most common in the western areas of the country. Bolo tie slides and tips in silver have been part of Hopi, Navajo, Zuni, and Puebloan silversmithing traditions since the mid-20th century. The bolo tie was made the official neckwear of Arizona on April 22, 1971 by Governor Jack Williams. New Mexico passed a non-binding measure to designate the bolo as the state's official neckwear in 1987. On March 13, 2007, New Mexico Governor Bill Richardson signed into law that the bolo tie was the state's official tie. Also in 2007, the bolo tie was named the official tie of Texas. In the United Kingdom, bolo ties are known as bootlace ties. They were popular with 1950s Ted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
College (US)
A college (Latin: ''collegium'') is an educational institution or a constituent part of one. A college may be a degree-awarding tertiary educational institution, a part of a collegiate or federal university, an institution offering vocational education, or a secondary school. In most of the world, a college may be a high school or secondary school, a college of further education, a training institution that awards trade qualifications, a higher-education provider that does not have university status (often without its own degree-awarding powers), or a constituent part of a university. In the United States, a college may offer undergraduate programs – either as an independent institution or as the undergraduate program of a university – or it may be a residential college of a university or a community college, referring to (primarily public) higher education institutions that aim to provide affordable and accessible education, usually limited to two-year assoc ...

Color Blind
Color blindness or color vision deficiency (CVD) is the decreased ability to see color or differences in color. It can impair tasks such as selecting ripe fruit, choosing clothing, and reading traffic lights. Color blindness may make some academic activities more difficult. However, issues are generally minor, and the colorblind automatically develop adaptations and coping mechanisms. People with total color blindness (achromatopsia) may also be uncomfortable in bright environments and have decreased visual acuity. The most common cause of color blindness is an inherited problem or variation in the functionality of one or more of the three classes of cone cells in the retina, which mediate color vision. The most common form is caused by a genetic disorder called congenital red–green color blindness. Males are more likely to be color blind than females, because the genes responsible for the most common forms of color blindness are on the X chromosome. Non-color-blind fem ...

Phi Beta Kappa
The Phi Beta Kappa Society () is the oldest academic honor society in the United States, and the most prestigious, due in part to its long history and academic selectivity. Phi Beta Kappa aims to promote and advocate excellence in the liberal arts and sciences, and to induct the most outstanding students of arts and sciences at only select American colleges and universities. It was founded at the College of William and Mary on December 5, 1776, as the first collegiate Greek-letter fraternity and was among the earliest collegiate fraternal societies. Since its inception, 17 U.S. Presidents, 40 U.S. Supreme Court Justices, and 136 Nobel Laureates have been inducted members. Phi Beta Kappa () stands for ('), which means "Wisdom it. love of knowledgeis the guide it. helmsmanof life". Membership Phi Beta Kappa has chapters in only about 10% of American higher learning institutions, and only about 10% of these schools' Arts and Sciences graduates are invited to join the society. ...

Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

High School
A secondary school describes an institution that provides secondary education and also usually includes the building where this takes place. Some secondary schools provide both '' lower secondary education'' (ages 11 to 14) and ''upper secondary education'' (ages 14 to 18), i.e., both levels 2 and 3 of the ISCED scale, but these can also be provided in separate schools. In the US, the secondary education system has separate middle schools and high schools. In the UK, most state schools and privately-funded schools accommodate pupils between the ages of 11–16 or 11–18; some UK private schools, i.e. public schools, admit pupils between the ages of 13 and 18. Secondary schools follow on from primary schools and prepare for vocational or tertiary education. Attendance is usually compulsory for students until age 16. The organisations, buildings, and terminology are more or less unique in each country. Levels of education In the ISCED 2011 education scale levels 2 and 3 c ...
