正在漫长的岁月中,人类对自己生存的空间产生过各种遐想。大地有尽头吗?它是方的还是圆的?为什么日、月、星辰总是东升西落?为什么会有四季变化等等。从1492年,哥伦布首航发现美洲大陆开始,人类进入了地球地理发现的时代,这个阶段持续了400年。到20世纪初期,地球上的所有地方都被绘制在地图上,其中有3个地点虽然被人所知,但没有人去过。它们就是被称为极地的"北极""南极"和地球上的最高点——珠穆朗玛峰(以下简称珠峰)。 相似文献

Third parties were a persistent and important aspect of American politics after the Civil War and have been as well a continuing focus of scholarly interest. This article discusses both the history and the historiography of the most prominent third party by examining the attitudes and actions of Herman E. Taubeneck, the national chairman of the People's or Populist Party. Taubeneck drew from his participation in and study of American politics to formulate a set of laws that he believed defined the creation, organization, direction, and success of third parties in the American political context. His analysis remarkably foreshadowed the ways in which modern scholars, drawing from several different disciplinary perspectives and methodologies, have only recently begun to explain and clarify the complex course of Populism. But Taubeneck's incomplete application of his own principles helped to disrupt and destroy the Populist Party itself. 相似文献

Based upon evidence from archives in Russia, Georgia, Latvia and Estonia, this article examines the ways in which the USSR’s Communist Youth League (Komsomol) worked to advance the Soviet cause among world youth during the Cold War. These ranged from cultural propaganda through to attempts at political subversion, and played a role not just in fortifying the regime’s international standing but also serving important domestic purposes at the same time. 相似文献
