   Extractions: (Kimberling 1998, p. 47). Note that extreme care is needed when consulting the literature , since reversing the order in which the points of the triangle are labeled results in exchanging the Brocard points. The second Brocard point is the interior point (also denoted or ) for which the angles and are equal, with the unique such angle denoted It is not a triangle center , but has trilinear coordinates

   Extractions: CANTOR, GEORG (1845-1918 C.E.) Georg Cantor was one of the most assailed mathematicians in history. He developed the modern theory on infinite sets. Despite the irony of spending his later year in mental institution, Georg Cantor was recognized for his lifetime echievement by the Royal Society of London and was made a member of to other Societies for Mathematics and Sciences.
