Maria Gaetana Agnesi
Maria Gaetana Agnesi is best known from the curve called the "Witch of Agnesi"Agnesi wrote the equation of this curve in the form y = a*sqrt(a*x-x*x)/x because she considered the x-axis to be the vertical axis and the y-axis to be the horizontal axis -
Virginia Ragsdale
Ragsdale's main conjecture was the following. Assume that an algebraic curve of degree 2k contains p even and n odd ovals, then Ragsdale conjectured that p ≤ 3k(k-1)/2 + 1
n ≤ 3k(k-1)/2. She also posed the inequality | 2(p-n)-1 | ≤ 3k2 - 3k +1, (which was later proved by Petrovskii) and showed that this inequality cannot be improved -
Hertha Marks Ayrton
In 1884 she invented a draftsman's device that could be used for dividing up a line into equal parts as well as for enlarging and reducing figures. She was also active in devising and solving mathematical problems -
Mary G. Ross
in 1942. During the first two and a half years at Lockheed, Mary assisted with developing fighter planes. She applied her mathematical expertise to researching compressibility effects on the relatively large P-28 fighter plane, as it reached the sound barrier. Impressed with her performance and motivated by events of the second world war, -
Julia Bowman Robinson
Her thesis showed that the notion of an integer can be defined arithmetically in terms of the notion of a rational number and the operations of addition and multiplication on the rationals. The arithmetic of rationals is therefore adequate for the formulation of all problems of elementary number theory -
Gloria Olive
The chapter titles are as follows: (1) "Mathematical Recreations," (2) "What Is Mathematics?" (3) "Logic," (4) "Sets and Paradoxes," (5) "Geometry," (6) "Counting and Probability," (7) "Statistics," (8) "Linear Algebra," (9) "Game Theory," (10) "Calculus," (11) "Computers," and there is an appendix on the real number system. The first four chapters do not require any algebra; Chapter 5 introduces some basic rules of algebra via geometry; and the appendix presents some basic properties of the rea -
Evelyn Boyd Granville
studying under the mathematics scholars on the Yale faculty. Dr. Einar Hille, a distinguished mathematician in the field of functional analysis -
Mary Gray
Her thesis dissertation was entitled "Radical Subcategories." An article with this title was published in the Pacific Journal of Mathematics, Vol. 23 (1967), -
Linda Preiss Rothschild
The work of Baouendi and Rothschild has had and continues to have tremendous impact on the theory of several complex variables. -
Sophie Germain
She was born on April 1, 1776. She died on June 27, 1831. She contributed to system of equations. Se also did alot of work with exponents.
