She is best known for early work on linear algebra in infinite dimensions, which has later become a part of functional analysis.Louise S. Grinstein and Paul J. Campbell, "Anna Anna Johnson Pell Wheeler: Her life and work, Historia Mathematica 9(1982)37–53 Biography Anna Johnson was born on May 5, 1883, to Swedish immigrant parents in Calliope, Iowa in the United States.

Calliope, Iowa
Calliope, Iowa was an incorporated town in northwestern Iowa. Calliope was formally incorporated in 1882. It served as the county seat of Sioux County, Iowa. The town of Calliope was annexed by the neighboring town of Hawarden, Iowa in 1893. History The Dutch settlers of Sioux County found politics and county offices in the hands of a few Americans at Calliope, Iowa. The town was laid out in 1860 on the Big Sioux River and less than one mile north of the business section of the present town of Hawarden. A portion of it is now included within the corporate limits of Hawarden and is still often referred to as Calliope. Calliope was the county seat from 1860 until 1872 when thereafter, it changed to Orange City, Post Office, 1862 to 1863, and again from 1869 to 1911. The Dutch Americans felt they had a right to vote because they were the same as the Americans. This did not sit well with some American settlers.

Marion Cameron Gray
Marion Gray (26 March 1902 – 16 September 1979) was a Scottish mathematician who discovered a graph with 54 vertices and 81 edges while working at American Telephone & Telegraph. The graph is commonly known as the Gray graph. Early life and education Marion Gray was born in Ayr, Scotland on 26 March 1902 to Marion (née Cameron) and James Gray. She attended Ayr Grammar School (1907–1913) and Ayr Academy (1913–1919). In 1919 she entered the University of Edinburgh where she graduated in 1922 with a first class honours in mathematics and natural philosophy. She continued on at the University for a further two years as a post doctoral student in mathematics where she was supervised by E.T. Whittaker. She joined the Edinburgh Mathematical Society where she presented several of her papers including 'The equation of telegraphy' and 'The equation of conduction of heat'.

Master's Degree
A master's degree (from Latin ) is a postgraduate academic degree awarded by universities or colleges upon completion of a course of study demonstrating mastery or a high-order overview of a specific field of study or area of professional practice. A master's degree normally requires previous study at the bachelor's degree, bachelor's level, either as a separate degree or as part of an integrated course. Within the area studied, master's graduates are expected to possess advanced knowledge of a specialized body of theoretical and applied topics; high order skills in analysis [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Private School
A private school or independent school is a school not administered or funded by the government, unlike a State school, public school. Private schools are schools that are not dependent upon national or local government to finance their financial endowment. Unless privately owned they typically have a board of governors and have a system of governance that ensures their independent operation. Private schools retain the right to select their students and are funded in whole or in part by charging their students for Tuition payments, tuition, rather than relying on taxation through public (government) funding; at some private schools students may be eligible for a scholarship, lowering this tuition fee, dependent on a student's talents or abilities (e.g., sports scholarship, art scholarship, academic scholarship), need for financial aid, or Scholarship Tax Credit, tax credit scholarships that might be available. Roughly one in 10 U.S. families have chosen to enroll their childr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Västergötland
Västergötland (), also known as West Gothland or the Latinized version Westrogothia in older literature, is one of the 25 traditional non-administrative provinces of Sweden (''landskap'' in Swedish), situated in the southwest of Sweden. Västergötland is home to Gothenburg, the second largest city in Sweden, which is situated along a short stretch of the Kattegat strait. The province is bordered by Bohuslän, Dalsland, Värmland, Närke, Östergötland, Småland and Halland, as well as the two largest Swedish lakes Vänern and Vättern. Victoria, Crown Princess of Sweden is Duchess of Västergötland. Administration The provinces of Sweden serve no administrative function. Instead, that function is served by counties of Sweden. From the 17th century up until 31 December 1997, Västergötland was divided into Skaraborg County, Älvsborg County and a minor part of Gothenburg and Bohus County. From 1 January 1998 nearly all of the province is in the newly created Väs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Functional Analysis
Functional analysis is a branch of mathematical analysis, the core of which is formed by the study of vector spaces endowed with some kind of limit-related structure (for example, Inner product space#Definition, inner product, Norm (mathematics)#Definition, norm, or Topological space#Definitions, topology) and the linear transformation, linear functions defined on these spaces and suitably respecting these structures. The historical roots of functional analysis lie in the study of function space, spaces of functions and the formulation of properties of transformations of functions such as the Fourier transform as transformations defining, for example, continuous function, continuous or unitary operator, unitary operators between function spaces. This point of view turned out to be particularly useful for the study of differential equations, differential and integral equations. The usage of the word ''functional (mathematics), functional'' as a noun goes back to the calculus of v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians was Thales of Miletus (); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales's theorem. The number of known mathematicians grew when Pythagoras of Samos () established the Pythagorean school, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman math ...

Linear Differential Equation
In mathematics, a linear differential equation is a differential equation that is linear equation, linear in the unknown function and its derivatives, so it can be written in the form a_0(x)y + a_1(x)y' + a_2(x)y'' \cdots + a_n(x)y^ = b(x) where and are arbitrary differentiable functions that do not need to be linear, and are the successive derivatives of an unknown function of the variable . Such an equation is an ordinary differential equation (ODE). A ''linear differential equation'' may also be a linear partial differential equation (PDE), if the unknown function depends on several variables, and the derivatives that appear in the equation are partial derivatives. Types of solution A linear differential equation or a system of linear equations such that the associated homogeneous equations have constant coefficients may be solved by quadrature, which means that the solutions may be expressed in terms of antiderivative, integrals. This is also true for a linear equation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
