Elkhart, Indiana
Elkhart ( ) is a city in Elkhart County, Indiana, United States. The population was 53,923 at the 2020 census. The city is located east of South Bend, Indiana. It is the most populous city in the Elkhart–Goshen metropolitan area, which in turn is part of the South Bend–Elkhart–Mishawaka combined statistical area, in a region commonly known as Michiana. History When the Northwest Territory was organized in 1787, the area now known as Elkhart was mainly inhabited by the Ottawa, Chippewa, and Potawatomi Indian tribes. In 1829, the Village of Pulaski was established, consisting of a post office, mill, and a few houses on the north side of the St. Joseph River (Lake Michigan), St. Joseph River. Dr. Havilah Beardsley moved westward from Ohio, and on August 9, 1821, purchased one square mile of land from Pierre Moran (a half-French, half-Native American Potawatomi Chief) in order to establish a rival town named Elkhart. The town of Elkhart was first plotted with 48 lots on Apri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California () is a state in the Western United States that lies on the Pacific Coast. It borders Oregon to the north, Nevada and Arizona to the east, and shares an international border with the Mexican state of Baja California to the south. With almost 40million residents across an area of , it is the largest state by population and third-largest by area. Prior to European colonization, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America. European exploration in the 16th and 17th centuries led to the colonization by the Spanish Empire. The area became a part of Mexico in 1821, following its successful war for independence, but was ceded to the United States in 1848 after the Mexican–American War. The California gold rush started in 1848 and led to social and demographic changes, including depopulation of Indigenous tribes. It organized itself and was admitted as the 31st state in 1850 as a free state, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

College Of William & Mary Faculty
A college (Latin: ''collegium'') may be a tertiary education, tertiary educational institution (sometimes awarding academic degree, degrees), part of a collegiate university, an institution offering vocational education, a further education institution, 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 education, 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 colleges in the United States, community college, referring to (primarily public) higher education institutions that aim to provide affordable and ...

Linear Algebra
Linear algebra is the branch of mathematics concerning linear equations such as :a_1x_1+\cdots +a_nx_n=b, linear maps such as :(x_1, \ldots, x_n) \mapsto a_1x_1+\cdots +a_nx_n, and their representations in vector spaces and through matrix (mathematics), matrices. Linear algebra is central to almost all areas of mathematics. For instance, linear algebra is fundamental in modern presentations of geometry, including for defining basic objects such as line (geometry), lines, plane (geometry), planes and rotation (mathematics), rotations. Also, functional analysis, a branch of mathematical analysis, may be viewed as the application of linear algebra to Space of functions, function spaces. Linear algebra is also used in most sciences and fields of engineering because it allows mathematical model, modeling many natural phenomena, and computing efficiently with such models. For nonlinear systems, which cannot be modeled with linear algebra, it is often used for dealing with first-order a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Olga Taussky Todd
Olga Taussky-Todd (August 30, 1906 – October 7, 1995) was an Austrian and later Czech-American mathematician. She published more than 300 research papers on algebraic number theory, integral matrices, and matrices in algebra and analysis. Early life Olga Taussky was born into a Jewish family in what is now Olomouc, Czech Republic, on August 30, 1906. Her father, Julius David Taussky, was an industrial chemist and her mother, Ida Pollach, was a housewife. She was the second of three children. Her father preferred that, if his daughters had careers, they be in the arts, but they all went into the sciences. Ilona, three years older than Olga, became a consulting chemist in the glyceride industry, and Hertha, three years younger than Olga, became a pharmacist and later a clinical chemist at Cornell University Medical College in New York City. At the age of three, her family moved to Vienna and lived there until the middle of World War I. Later Taussky's father accepted a position ...

California Institute Of Technology
The California Institute of Technology (branded as Caltech) is a private research university in Pasadena, California, United States. The university is responsible for many modern scientific advancements and is among a small group of institutes of technology in the United States that are devoted to the instruction of pure and applied sciences. The institution was founded as a preparatory and vocational school by Amos G. Throop in 1891 and began attracting influential scientists such as George Ellery Hale, Arthur Amos Noyes, and Robert Andrews Millikan in the early 20th century. The vocational and preparatory schools were disbanded and spun off in 1910, and the college assumed its present name in 1920. In 1934, Caltech was elected to the Association of American Universities, and the antecedents of NASA's Jet Propulsion Laboratory, which Caltech continues to manage and operate, were established between 1936 and 1943 under Theodore von Kármán. Caltech has six academic divisi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
