It had been understood in a number of (non-equivalent) ways – that parallel lines remain equidistant from each other, that non-parallel lines intersect, that if the lines L1 and L2 in the diagram are parallel then A + B = 180 degrees, that there can only be one line through a point parallel to any given line. The limit distributions of U- and V-statistics for both independent and weakly dependent observations cannot be used directly since they depend on certain parameters which in turn depend on the underlying situation in a complicated way.

He was excited by information about NNC that we had posted on the Internet, and wanted to learn more Euclidean Plane and its Relatives: A minimalistic introduction. If working in a domain where the squares are additive, as is common the case when estimating the variance of a sum of independent random variables, then the quadratic calculi may produce meaningful models." Application of non-Newtonian calculus to information technology was made by S Taxicab Geometry: Adventure in Non-Euclidean Geometry (Addison-Wesley innovative series). It opens the question to know if there are major fields of economic analysis which can be profoundly re-thought in the light of this discovery." - Diana Andrada Filip (Babes-Bolyai University of Cluj-Napoca in Romania) and Cyrille Piatecki (Orléans University in France); from their 2014 article [82]. "In this paper, after a brief presentation of [the geometric] calculus, we try to show how it could be used to re-explore from another perspective classical economic theory, more particularly economic growth and the maximum-likelihood method from statistics." - Diana Andrada Filip (Babes-Bolyai University of Cluj-Napoca in Romania) and Cyrille Piatecki (Orléans University in France); from their 2014 article [181]. "... [non-Newtonian calculus] could help to acquire new insight on classical subjects, or solve directly some problems which could only be reached by approximations." - Diana Andrada Filip (Babes-Bolyai University of Cluj-Napoca in Romania) and Cyrille Piatecki (Orléans University in France); from their 2014 article [181]. "The double-entry bookkeeping promoted by Luca Pacioli in the fifteenth century could be considered a strong argument in behalf of the multiplicative calculus, which can be developed from the Grossman and Katz non-Newtonian calculus concept." (The expression "multiplicative calculus" refers here to the geometric calculus.) - Diana Andrada Filip (Babes-Bolyai University of Cluj-Napoca in Romania) and Cyrille Piatecki (Orléans University in France); from their 2014 article [149]. "The results of this study are also expected to help researchers, practitioners, economists, business managers, and cost and managerial accountants to understand how to construct a multiplicative based learning curve to improve such decisions as pricing, profit planning, capacity management, and budgeting." - Hasan Özyapıcı (Eastern Mediterranean University in Cyprus), İlhan Dalcı (Eastern Mediterranean University in Cyprus), and Ali Ozyapici (Cyprus International University); from their article "Integrating accounting and multiplicative calculus: an effective estimation of learning curve". [290] (The expression "multiplicative calculus" refers here to the geometric calculus.) "This work is aimed to show that various problems from different fields can be modeled more efficiently using [geometric] calculus, in place of Newtonian calculus. ..

Coley [1862 - 1936] injected streptococcal organisms into a patient with inoperable cancer. He thought that the infection he produced would have the side effect of shrinking the malignant tumor. He was successful, and this was one of the first examples of immunotherapy. ... William Coley's intuitions were correct: Stimulating the immune system may be effective in treating cancer. .. Lectures on Vector Bundles over Riemann Surfaces. (MN-6). His most important discovery was ideal numbers; this led to the theory of ideals and p-adic numbers; this discovery's revolutionary nature has been compared to that of non-Euclidean geometry. Kummer is famous for his attempts to prove, with the aid of his ideal numbers, Fermat's Last Theorem 15 Subtraction Worksheets with 5-Digit Minuends, 1-Digit Subtrahends: Math Practice Workbook (15 Days Math Subtraction Series).

The other two angles of a Saccheri quadrilateral are called the summit angles and they have equal measure. The summit angles of a Saccheri quadrilateral are acute if the geometry is hyperbolic, right angles if the geometry is Euclidean and obtuse angles if the geometry is elliptic A History of Non-Euclidean Geometry.. This version of the notes comes complete with the problem sets, giving a complete course. For students who want to learn geometry from a modern point of view quickly and not to get sidetracked with minutia, these notes will be just the ticket Taxicab Geometry: An Adventure in Non-Euclidean Geometry by Krause, Eugene F. published by Dover Publications (1987). If a meta-model is primarily concerned with learning probabilities, non-parametric distributions, or anything else where the multiplication is the primary operation, then the geometric calculi may be of interest. If working in a domain where the squares are additive, as is common the case when estimating the variance of a sum of independent random variables, then the quadratic calculi may produce meaningful models." In the first case, replacing the parallel postulate (or its equivalent) with the statement "In a plane, given a point P and a line ℓ not passing through P, there exist two lines through P which do not meet ℓ" and keeping all the other axioms, yields hyperbolic geometry. [18] The second case is not dealt with as easily Full Color Illustrations of the Fourth Dimension, Volume 1: Tesseracts and Glomes. In the other kind, the mind goes from the means to the goal, that is, the mind first discovers a fact and then seeks a use for it. In mathematics, and elsewhere, most significant discoveries are of the second kind. ... An outstanding example in mathematics is the exhaustive study of the conics by the Greeks, and then, some two thousand years later, Kepler's stunning application of the Greek findings to the movement of the planets in the solar system." - Howard Eves, from his book Mathematical Circles Squared, pages 167 and 168 (1972). "... we find in the history of ideas mutations which do not seem to correspond to any obvious need, and at first sight appear as mere playful whimsies - such as Apollonius' work on conic sections, or the non-Euclidean geometries, whose practical value became apparent only later." - Arthur Koestler, from his book The Sleepwalkers (1959). "Newton's epoch-making works (1669, 1671) were offered to the Royal Society and Cambridge University Press but, incredible as it now seems, were rejected for publication." - John Stillwell, from his book Mathematics and Its History (2010). "More than 350 years after the Roman Catholic Church condemned Galileo, Pope John Paul II is poised to rectify one of the Church's most infamous wrongs -- the persecution of the Italian astronomer and physicist for proving the Earth moves around the Sun." - Alan Cowell, from his article "After 350 Years, Vatican Says Galileo Was Right: It Moves" in The New York Times, 31 October 1992. "Yet Gauss, universally regarded as the foremost mathematician of his day, did not publicize his findings. .. Euclidean and Non-Euclidean Geometry.

The study of lines that are allowed to correspond to linear continua (curves) is called topology. Two-dimensional topology is sometimes loosely referred to as "rubber sheet geometry" because it does not allow cutting apart or sealing together, but deformations are permitted Full Color Illustrations of the Fourth Dimension, Volume 2: Hypercube- and Hypersphere-Based Objects. Using Active Geometry at the beginning of various sections allows professors to give students a somewhat more intuitive introduction using current technology before moving on to more abstract concepts and theorems.

[184] "In 2011, Bashirov et al. ["On modeling with multiplicative differential equations"] exploit the efficiency of [the geometric] calculus over the Newtonian calculus The Theory of the Imaginary in Geometry: Together with the Trigonometry of the Imaginary. This diagram tries to illustrate this situation in 2 dimensions, although its a bit misleading, because we have drawn it on a plane so we could have drawn rectangular coordinates. To try to illustrate a situation where this is impossible we could think of a two dimensional plane which has been stretched into the third dimension D-Modules and Spherical Representations. (MN-39): (Princeton Legacy Library). For 2,000 years the geometry of Euclid's Elements was assumed to be the one true geometry. Despite doubts about Euclid's parallel postulate, all attempts to derive it from his other four postulates or to develop other geometries without it were futile until the 19th century. The tremendous productivity of mathematicians since the early 19th century has led to the development of several types of geometries, some of which are identified below Geometries, Groups and Algebras in the Nineteenth Century - A History. Altogether a very great man, he started many branches of mathematics from scratch, but he acknowledged himself that he didn't prove any difficult theorem and cared about proofs less than about concepts." - Benoit Mandelbrot, from the interview "A Radical Mind" with Benoit Mandelbrot, conducted by Bill Jersey on 24 April 2005, posted at PBS's NOVA Online on 01 October 2008, and broadcast on PBS's NOVA television-program Hunting the Hidden Dimension on 24 August 2011.
