Among the many beautiful and nontrivial theorems in geometry found in Geometry Revisited are the theorems of Ceva, Menelaus, Pappus, Desargues, Pascal, and Brianchon. A nice proof is given of Morley’s remarkable theorem on angle trisectors. The transformational point of view is emphasized: reflections, rotations, translations, similarities, inversions, and affine and projective...(展开全部)

Today we are politically polarized as never before. The presidential elections of 2000 and 2004 will be remembered as two of the most contentious political events in American history. Yet despite the recent election upheaval, The American Voter Revisited discovers that voter behavior has been remarkably consistent over the last half century. And if the authors are correct in th...(展开全部)

This text is the fifth and final in the series of educational books written by Israel Gelfand with his colleagues for high school students. These books cover the basics of mathematics in a clear and simple format – the style Gelfand was known for internationally. Gelfand prepared these materials so as to be suitable for independent studies, thus allowing students to learn and p...(展开全部)

Fin de siecle Vienna was once memorably described by Karl Kraus as a "proving ground for the destruction of the world". In the decades leading to the World War that brought down the Austro-Hungarian empire, the city was at once an operetta dream world masking social and political problems and tension, as well as a center for the far-reaching explorations and innovations in musi...(展开全部)
