The Theatrical Cipher Code

"As gripping as a good thriller." --The Washington Post Unpack the science of secrecy and discover the methods behind cryptography--the encoding and decoding of information--in this clear and easy-to-understand young adult adaptation of the national bestseller that's perfect for this age of WikiLeaks, the Sony hack, and other events that reveal the extent to which our technology is never quite as secure as we want to believe. Coders and codebreakers alike will be fascinated by history's most mesmerizing stories of intrigue and cunning--from Julius Caesar and his Caeser cipher to the Allies' use of the Enigma machine to decode German messages during World War II. Accessible, compelling, and timely, The Code Book is sure to make readers see the past--and the future--in a whole new way. "Singh's power of explaining complex ideas is as dazzling as ever." --The Guardian

The first of its kind, this collection of critical essays opens up new venues in the comparative study of science and culture by focusing on the formative decades of modern China in the late nineteenth and first half of the twentieth century. It provides a wide-ranging examination of the cultural and intellectual history of science and technology in modern China.From anti-imperialism to the technology of Chinese writing, the commodification of novelties to the rise of the modern professional scientist, new lexica and appropriations of the past, the contributors map out a transregional and global circuitry of modern knowledge and practical know-how, nationalism and the amalgamation of new social practices. Contributors include: Iwo Amelung, Fa-ti Fan, Shen Guowei, Danian Hu, Joachim Kurtz, Eugenia Lean, Thomas S. Mullaney, Hugh Shapiro, Grace Shen, and Jing Tsu.

Theatrical Events. Borders, Dynamics and Frames is written to develop the concept of ‘Eventness’ in Theatre Studies. The book as a whole stresses the importance of understanding theatre performances as aesthetic-communicative encounters of a wide range of agents and aspects. The Theatrical Event concept means not only that performers and spectators meet, but also that the specific mental sets, backgrounds and cultural contexts they bring in, strongly contribute to the character of a particular event. Moreover, this concept gives space to the study of the role societal developments – such as technological, political, economical or educational ones – play in theatrical events.

Analyzes the basic duality of theatre (the play is happening on a stage, but the story is happening at some other place and time), exploring how the two aspects both compete and complement each other and suggesting the social factors that impact the total process.

The first edition of this award-winning book attracted a wide audience. This second edition is both a joy to read and a useful classroom tool. Unlike traditional textbooks, it requires no mathematical prerequisites and can be read around the mathematics presented. If used as a textbook, the mathematics can be prioritized, with a book both students and instructors will enjoy reading. Secret History: The Story of Cryptology, Second Edition incorporates new material concerning various eras in the long history of cryptology. Much has happened concerning the political aspects of cryptology since the first edition appeared. The still unfolding story is updated here. The first edition of this book contained chapters devoted to the cracking of German and Japanese systems during World War II. Now the other side of this cipher war is also told, that is, how the United States was able to come up with systems that were never broken. The text is in two parts. Part I presents classic cryptology from ancient times through World War II. Part II examines modern computer cryptology. With numerous real-world examples and extensive references, the author skillfully balances the history with mathematical details, providing readers with a sound foundation in this dynamic field. FEATURES Presents a chronological development of key concepts Includes the Vigenère cipher, the one-time pad, transposition ciphers, Jefferson’s wheel cipher, Playfair cipher, ADFGX, matrix encryption, Enigma, Purple, and other classic methods Looks at the work of Claude Shannon, the origin of the National Security Agency, elliptic curve cryptography, the Data Encryption Standard, the Advanced Encryption Standard, public-key cryptography, and many other topics New chapters detail SIGABA and SIGSALY, successful systems used during World War II for text and speech, respectively Includes quantum cryptography and the impact of quantum computers
