Robert Hallowell Richards
Robert Hallowell Richards (August 26, 1844 – March 27, 1945) was an American mining engineer, metallurgist, and educator, born at Gardiner, Maine. In 1868, with the first class to leave the institution, he graduated from the Massachusetts Institute of Technology, and there he taught for 46 years, becoming professor of mineralogy and assaying in 1871, head of the department of mining engineering in 1873, and in 1884 professor also of metallurgy. The laboratories which he established at the Institute were the first of their kind in the world. He retired in 1914. Richards invented a jet aspirator for chemical and physical laboratories and a prism for stadia surveying. But it was in the field of ore dressing that he became especially distinguished. He determined the curves of material settling in water, thereby establishing the fundamental principles of sorting ore by means of jigs and other machines. He invented separators for Lake Superior copper, Virginia iron, and three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Massachusetts Institute Of Technology
The Massachusetts Institute of Technology (MIT) is a private land-grant research university in Cambridge, Massachusetts. Established in 1861, MIT has played a key role in the development of modern technology and science, and is one of the most prestigious and highly ranked academic institutions in the world. Founded in response to the increasing industrialization of the United States, MIT adopted a European polytechnic university model and stressed laboratory instruction in applied science and engineering. MIT is one of three private land grant universities in the United States, the others being Cornell University and Tuskegee University. The institute has an urban campus that extends more than a mile (1.6 km) alongside the Charles River, and encompasses a number of major off-campus facilities such as the MIT Lincoln Laboratory, the Bates Center, and the Haystack Observatory, as well as affiliated laboratories such as the Broad and Whitehead Institutes. , 98 ...

Western United States
The Western United States (also called the American West, the Far West, and the West) is the region comprising the westernmost states of the United States. As American settlement in the U.S. expanded westward, the meaning of the term ''the West'' changed. Before about 1800, the crest of the Appalachian Mountains was seen as the western frontier. The frontier moved westward and eventually the lands west of the Mississippi River were considered the West. The U.S. Census Bureau's definition of the 13 westernmost states includes the Rocky Mountains and the Great Basin to the Pacific Coast, and the mid-Pacific islands state, Hawaii. To the east of the Western United States is the Midwestern United States and the Southern United States, with Canada to the north, and Mexico to the south. The West contains several major biomes, including arid and semi-arid plateaus and plains, particularly in the American Southwest; forested mountains, including three major ranges, the Sierra Neva ...

People From Gardiner, Maine
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Ellen Swallow Richards
Ellen Henrietta Swallow Richards (December 3, 1842 – March 30, 1911) was an American industrial and safety engineer, environmental chemist, and university faculty member in the United States during the 19th century. Her pioneering work in sanitary engineering, and experimental research in domestic science, laid a foundation for the new science of home economics. She was the founder of the home economics movement characterized by the application of science to the home, and the first to apply chemistry to the study of nutrition. Richards graduated from Westford Academy (second oldest secondary school in Massachusetts) in 1862. She was the first woman admitted to the Massachusetts Institute of Technology. She graduated in 1873 and later became its first female instructor. Richards was the first woman in America accepted to any school of science and technology, and the first American woman to obtain a degree in chemistry, which she earned from Vassar College in 1870.

Book
A book is a medium for recording information in the form of writing or images, typically composed of many pages (made of papyrus, parchment, vellum, or paper) bound together and protected by a cover. The technical term for this physical arrangement is '' codex'' (plural, ''codices''). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page. As an intellectual object, a book is prototypically a composition of such great length that it takes a considerable investment of time to compose and still considered as an investment of time to read. In a restricted sense, a book is a self-sufficient section or part of a longer composition, a usage reflecting that, in antiquity, long works had to be written on several scrolls and each scroll had to be identified by the book it contained. Each part of Aristotle's ''Physics'' is called a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Institute Of Mining, Metallurgical, And Petroleum Engineers
The American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME) is a professional association for mining and metallurgy, with over 145,000 members. It was founded in 1871 by 22 mining engineers in Wilkes-Barre, Pennsylvania, United States, being one of the first national engineering societies in the country. Its charter is to "advance and disseminate, through the programs of the Member Societies, knowledge of engineering and the arts and sciences involved in the production and use of minerals, metals, energy sources and materials for the benefit of humankind." It is the parent organization of four Member Societies, the Society for Mining, Metallurgy, and Exploration (SME), The Minerals, Metals & Materials Society (TMS), the Association for Iron and Steel Technology (AIST), and the Society of Petroleum Engineers (SPE). The organization is currently based in Dove Valley, Colorado. History Known by its original name 'American Institute of Mining Engineers'' (AIM ...
