Magical American Jew The Enigma of Difference in Contemporary Jewish American Short Fiction and Film


Free Download Aaron Tillman, "Magical American Jew: The Enigma of Difference in Contemporary Jewish American Short Fiction and Film"
English | ISBN: 1498565026 | 2017 | 158 pages | EPUB | 494 KB
Efforts to describe contemporary Jewish American identities often reveal more questions than concrete articulations, more statements about what Jewish Americans are not than what they are. Highlighting the paradoxical phrasings that surface in contemporary writings about Jewish American literature and culture-language that speaks to the elusive difference felt by many Jewish Americans-Aaron Tillman asks how we portray identities and differences that seem to resist concrete definition. Over the course of Magical American Jew, Tillman examines this enigma-the indefinite yet undeniable difference that informs contemporary Jewish American identity-demonstrating how certain writers and filmmakers have deployed magical realist techniques to illustrate the enigmatic difference that Jewish Americans have felt and continue to feel.

Oliver Heaviside’s electromagnetic investigations – from the publication of his first electrical paper in 1972 to the public recognition awarded to him by Lord Kelvin in 1889 – have consistently attracted attention over the years, and of late have become a major source for the study of the development of field theory after Maxwell.

Coding Theory and Cryptography From Enigma and Geheimschreiber to Quantum Theory


Free Download Coding Theory and Cryptography: From Enigma and Geheimschreiber to Quantum Theory by David Joyner
English | PDF (True) | 2000 | 264 Pages | ISBN : 3540663363 | 35.5 MB
These are the proceedings of the Conference on Coding Theory, Cryptography, and Number Theory held at the U. S. Naval Academy during October 25-26, 1998. This book concerns elementary and advanced aspects of coding theory and cryptography. The coding theory contributions deal mostly with algebraic coding theory. Some of these papers are expository, whereas others are the result of original research. The emphasis is on geometric Goppa codes (Shokrollahi, Shokranian-Joyner), but there is also a paper on codes arising from combinatorial constructions (Michael). There are both, historical and mathematical papers on cryptography. Several of the contributions on cryptography describe the work done by the British and their allies during World War II to crack the German and Japanese ciphers (Hamer, Hilton, Tutte, Weierud, Urling). Some mathematical aspects of the Enigma rotor machine (Sherman) and more recent research on quantum cryptography (Lomonoco) are described. There are two papers concerned with the RSA cryptosystem and related number-theoretic issues (Wardlaw, Cosgrave).

The Enigma of the Origin of Portolan Charts A Geodetic Analysis of the Hypothesis of a Medieval Origin


Free Download The Enigma of the Origin of Portolan Charts: A Geodetic Analysis of the Hypothesis of a Medieval Origin by Roel Nicolai
English | 2016 | ISBN: 9004282971 | 572 pages | PDF | 23 Mb
The sudden appearance of portolan charts, realistic nautical charts of the Mediterranean and Black Sea, at the end of the thirteenth century is one of the most significant occurrences in the history of cartography. Using geodetic and statistical analysis techniques these charts are shown to be mosaics of partial charts that are considerably more accurate than has been assumed. Their accuracy exceeds medieval mapping capabilities. These sub-charts show a remarkably good agreement with the Mercator map projection. It is demonstrated that this map projection can only have been an intentional feature of the charts’ construction. Through geodetic analysis the author eliminates the possibility that the charts are original products of a medieval Mediterranean nautical culture, which until now they have been widely believed to be.
