Aristotle wrote a book called "TOPICS" which started out with a discussion of deductive logic. The whole world reestablished this book starting with the Islamic translation on through time. THALES, FOUNDER OF GREEK GEOMETRY (585 B.C.E.) The birth of Greek astronomy has been attributed to Thales of Miletus. Thales brought from Egypt a number of fundamental geometric principles. Thales, an Ionian (western border of Asia Minor) who was active near the start of the sixth century bc has been credited with a number of geometric theorems. 1. A Circle is bisected by its diameter. 2. Angles at the base of any isosceles triangle are equal. 3. If two straight lines intersect the opposite angles formed are equal. 4. If two triangles have two angles and one side respectively equal, the triangles are equal in all respects. Thales was also well known for forecasting the solar eclipse, so he was also considered a scientist.

28. TRIANGLE GEOMETERS
    Court also describes seminal papers by henri brocard and J. Neuberg and namesLemoine, brocard, and Neuberg as the three cofounders of modern triangle  
    http://faculty.evansville.edu/ck6/bstud/tg.html
    
    Extractions: Euclid's Elements and other remnants from ancient Greek times contain theorems about triangles and descriptions of four triangle centers: centroid, incenter, circumcenter, and orthocenter. Later triangle geometers include Euler, Pascal, Ceva, and Feuerbach. In 1873, Emile Lemoine presented a paper "on a remarkable point of the triangle," now known as the Lemoine point or symmedian point. This paper, writes Nathan Altshiller Court ( College Geometry , page 304), "may be said to have laid the foundations...of the modern geometry of the triangle as a whole." Court also describes seminal papers by Henri Brocard and J. Neuberg and names Lemoine, Brocard, and Neuberg as the three co-founders of modern triangle geometry. An astonishing wave of interest and publications in triangle geometry swept through the last years of the 19th century and then collapsed during the early years of the 20th. However, many new gemstones in the fields of triangle geometry remained to be unearthed with new excavating tools, such as computers and methods from other areas of mathematics. All of this has led to the state of the art up to 1995, as described in Philip J. Davis

    Extractions: Definition of bicentric pairs. Suppose f(a,b,c) : f(b,c,a) : f(c,a,b) is a point that satisfies requirement (1) in the definition of triangle center (in Glossary not f(a,b,c) : f(b,c,a) : f(c,a,b) and f(a,c,b) : f(b,a,c) : f(c,b,a) are a bicentric pair of points , or simply, a bicentric pair. The most widely studied example is the pair of Brocard points, given in trilinear coordinates by c/b : a/c : b/a and b/c : c/a : a/b. Following are operations which carry bicentric pairs P = p : q : r and U = u : v : w onto triangle centers. For two of these operations, it is necessary that p, q, r and u,v,w be represented by f(a,b,c), f(b,c,a), f(c,a,b) and f(a,c,b), f(b,a,c), f(c,b,a).

30. Russian Perfume At The Russian Shop In Lisle Illinois
    henri brocard, the founder of Europe s largest perfumery factory, was the greatestperfume maker of all times and nations. His factory was based in Moscow  
    http://www.therussianshop.com/russhop/imperial/perfume.htm
    
    Extractions: Henri Brocard, the founder of Europe's largest perfumery factory, was the "greatest perfume maker of all times and nations." His factory was based in Moscow. Born in France, Brocard came to Russia in 1861. For many years Brocard was chief scientist at his works and he became famous as an inventor of wonderful scents. His factory, renamed "Novaya Zarya", or "New Dawn" produced the scent called "The Empress's Favorite Bouquet" that in the Soviet era was renamed "Red Moscow" and became famous throughout the world. This high-quality perfume (a blend of jasmine and bergamot) is comparable to the best in the world. But at a price that only the Russians can afford to sell for. Large faceted bottle with spritzer holds 3.4 fl. oz. and comes with a decorative cap in the form of a cupola. Small bottle holds 1.35 fl. oz.

    Extractions: Topology Atlas Document # iaah-67 from CIM Bulletin #16 th January 1851. He went to school at his native village and to the Liceu in Lamego. After a period of uncertainty regarding his future, during which he hesitated between Theology and Mathematics, he entered the University of Coimbra, the only one in Portugal at the time, and completed his degree in Mathematics in 1885 with the highest classification. He was still a student when he published . He sent this work to Daniel Augusto da Silva (1814-1878), a Navy officer, author of some important work on Number Theory and on Mechanics, Professor at the Escola Naval in Lisbon and by then the most respected Portuguese mathematician. Da Silva acknowledged the reception of this work with words of high praise, encouragement and support. It was the beginning of a friendship that only finished with Da Silva's death. In 1875 Gomes Teixeira presented a thesis , with which he obtained his doctor degree again with the highest classification. The following year he obtained a professorship with the work . In 1878 he also became a member of the . Da Silva writes: This letter must have made a strong impression in the mind of the young mathematician, making him realise the isolation of the Portuguese scientific community. He soon began to fight this isolation: he wrote the main original results of his thesis in French and sent them to the

    Extractions: Apollonius (c262-190 BC): Alexandrian geometer author of various books including the lost book on plane loci which is known from various commentators to have given the theorem about circles associated with the angle bisectors of a triangle. Bodenmiller (19th century re-discovered the theorem about the midpoints of diagonals of a quadrilateral now also ascribed to Gauss. Henri Brocard (1845-1922): discovered a number of properties associated with the points, triangles and circles now named after him. Giovanni Ceva (?1647-?1736): discovered theorems about points on the sides of a triangle (see glossary); the one for collinear points is now ascribed to the first century Alexandrian geometer, Menelaus. Leopold Crelle (1780-1855): engineer and editor of famous mathematical journal; he discovered various properties of triangles including the points now named after Brocard. He claimed that "it is wonderful that so simple a figure as the triangle is so inexhaustible". Euclid (c300 BC): author of the Elements the influential systematic account of geometry including many theorems about triangles. Leonhard Euler (1707-1783): prolific Swiss mathematician who established that certain special points of a triangle lay on a line - now named after him.

    http://boisdejasmin.typepad.com/_/2005/06/russian_perfume.html
    
    Extractions: Main Krasnaya Moskva (Red Moscow) is a heavy carnation based fragrance, with a lemony coriander note slicing through the powderiness. The base features an interplay between cool and warm notes. I cannot even review Krasnaya Moskva on its merits alone, because the associations are too strong. The moment I smell it, I am 10 years old again, being lectured on the young pioneer’s creed by some female Communist Party functionary. Since Bolsheviks deemed perfumes as bourgeois extravagance, Krasnaya Moskva is the only Soviet Russian perfume I remember, along with something called Chypre . As a child, I recall buying a bottle for my grandfather, however my grandmother vetoed the present, referring to Chypre as something that alcoholics buy when vodka is out of stock. No wonder, it took me a long time to appreciate chypre fragrances.

40. Review Of The Changing Shape Of Geometry
    articles on Babylonian, Greek, Chinese, Islamic, Indian mathematics and therole of more recent mathematicians, Girard Desargues and henri brocard.  
    http://www.cut-the-knot.com/books/Reviews/changingshape.shtml
    
    Extractions: edited by Chris Pritchard The book is an expanded collection of 57 articles published in Mathematical Gazette and Mathematics in School Elements and geometry was universally "viewed as the ideal vehicle for developing an understanding of formal proof" (p. 3). The first Teaching Committee was formed thirty years later (1902) to help design curriculum, assist mathematics teachers with advice and resources, and "to seek to influence national policies on mathematics education." This book celebrates the first centenary of Teaching Committee. The tone for the book is set in the General Introduction The articles have been grouped into six parts. The selection of articles is excellent, starting with the two presidential addresses What Is Geometry? that constitute Part I. For G. H. Hardy (1925), geometry is a collection of logical systems, while "the elementary geometry of schools and universities is not this or that geometry, but a most disorderly and heterogeneous collection of fragments from a dozen geometries or more." For M. Atiyah (1982), "...geometry is that part of mathematics in which visual thought is dominant. ...geometry is not so much a branch of mathematics as a way of thinking that permeates all branches." Part II, The History of Geometry, gathers articles on Babylonian, Greek, Chinese, Islamic, Indian mathematics and the role of more recent mathematicians, Girard Desargues and Henri Brocard. A short article by J. H. Webb took me by surprise. I was unaware of the popular English definition of a straight line as "the shortest distance between two points." Webb traces the usage to a mistranslation of Legendre's
