Russian Philosophy in the Twenty-First Century: An Anthology provides the English-speaking world with access to post-Soviet philosophic thought in Russia for the first time. The Anthology presents the fundamental range of contemporary philosophical problems in the works of prominent Russian thinkers. In contrast to the "single-mindedness" of Soviet-era philosophers and the bias toward Orthodox Christianity of emigre philosophers, it offers to its readers the authors' plurality of different positions in widely diverse texts. Here one finds strictly academic philosophical works and those in an applied, pragmatic format-secular and religious-that are dedicated to complex social and political matters, to pressing cultural topics or insights into international terrorism, as well as to contemporary science and global challenges.

In Theory of Religious Cycles: Tradition, Modernity and the Baha'i Faith Mikhail Sergeev offers a new interpretation of the Soviet period of Russian history as a phase within the religious evolution of humankind by developing a theory of religious cycles, which he applies to modernity and to all the major world faiths of Judaism, Buddhism, Christianity, and Islam. Sergeev argues that in the course of its evolution religion passes through six common phases-formative, orthodox, classical, reformist, critical, and post-critical. Modernity, which was started by the European Enlightenment, represents the critical phase of Christianity, a systemic crisis that could be overcome with the appearance of new religious movements such as the Baha'i Faith, which offers a spiritual extension of the modern worldview.

The book introduces the basic foundations of high mathematics and vector algebra. Then, it explains the basic aspects of classical electrodynamics and electromagnetism. Based on such knowledge readers investigate various radio propagation problems related to guiding structures connecting electronic devices with antenna terminals placed at the different radar systems. It explains the role of antennas in process of transmission of radio signals between the terminals. Finally, it shows the relation between the main operational charactistics of each kind of radar and the corresponding knowledge obtained from the previous chapters.
