The Chinese Typewriter: A History (The\mit Press Ser.)

by Thomas S. Mullaney

How Chinese characters triumphed over the QWERTY keyboard and laid the foundation for China's information technology successes today.Chinese writing is character based, the one major world script that is neither alphabetic nor syllabic. Through the years, the Chinese written language encountered presumed alphabetic universalism in the form of Morse Code, Braille, stenography, Linotype, punch cards, word processing, and other systems developed with the Latin alphabet in mind. This book is about those encounters—in particular thousands of Chinese characters versus the typewriter and its QWERTY keyboard. Thomas Mullaney describes a fascinating series of experiments, prototypes, failures, and successes in the century-long quest for a workable Chinese typewriter. The earliest Chinese typewriters, Mullaney tells us, were figments of popular imagination, sensational accounts of twelve-foot keyboards with 5,000 keys. One of the first Chinese typewriters actually constructed was invented by a Christian missionary, who organized characters by common usage (but promoted the less-common characters for “Jesus" to the common usage level). Later came typewriters manufactured for use in Chinese offices, and typewriting schools that turned out trained “typewriter girls” and “typewriter boys.” Still later was the “Double Pigeon” typewriter produced by the Shanghai Calculator and Typewriter Factory, the typewriter of choice under Mao. Clerks and secretaries in this era experimented with alternative ways of organizing characters on their tray beds, inventing an input method that was the first instance of “predictive text.”Today, after more than a century of resistance against the alphabetic, not only have Chinese characters prevailed, they form the linguistic substrate of the vibrant world of Chinese information technology. The Chinese Typewriter, not just an “object history” but grappling with broad questions of technological change and global communication, shows how this happened.A Study of the Weatherhead East Asian InstituteColumbia University

Chips 2020: A Guide to the Future of Nanoelectronics (The Frontiers Collection)

by Bernd Hoefflinger

The chips in present-day cell phones already contain billions of sub-100-nanometer transistors. By 2020, however, we will see systems-on-chips with trillions of 10-nanometer transistors. But this will be the end of the miniaturization, because yet smaller transistors, containing just a few control atoms, are subject to statistical fluctuations and thus no longer useful. We also need to worry about a potential energy crisis, because in less than five years from now, with current chip technology, the internet alone would consume the total global electrical power! This book presents a new, sustainable roadmap towards ultra-low-energy (femto-Joule), high-performance electronics. The focus is on the energy-efficiency of the various chip functions: sensing, processing, and communication, in a top-down spirit involving new architectures such as silicon brains, ultra-low-voltage circuits, energy harvesting, and 3D silicon technologies. Recognized world leaders from industry and from the research community share their views of this nanoelectronics future. They discuss, among other things, ubiquitous communication based on mobile companions, health and care supported by autonomous implants and by personal carebots, safe and efficient mobility assisted by co-pilots equipped with intelligent micro-electromechanical systems, and internet-based education for a billion people from kindergarden to retirement. This book should help and interest all those who will have to make decisions associated with future electronics: students, graduates, educators, and researchers, as well as managers, investors, and policy makers.

Chips 2020 Vol. 2: New Vistas in Nanoelectronics (The Frontiers Collection)

by Bernd Hoefflinger

The release of this second volume of CHIPS 2020 coincides with the 50th anniversary of Moore's Law, a critical year marked by the end of the nanometer roadmap and by a significantly reduced annual rise in chip performance. At the same time, we are witnessing a data explosion in the Internet, which is consuming 40% more electrical power every year, leading to fears of a major blackout of the Internet by 2020. The messages of the first CHIPS 2020, published in 2012, concerned the realization of quantum steps for improving the energy efficiency of all chip functions. With this second volume, we review these messages and amplify upon the most promising directions: ultra-low-voltage electronics, nanoscale monolithic 3D integration, relevant-data, brain- and human-vision-inspired processing, and energy harvesting for chip autonomy. The team of authors, enlarged by more world leaders in low-power, monolithic 3D, video, and Silicon brains, presents new vistas in nanoelectronics, promising Moore-like exponential growth sustainable through to the 2030s.

Chiral and Topological Nature of Magnetic Skyrmions (Springer Theses)

by Shilei Zhang

This book focuses on the characterisation of the chiral and topological nature of magnetic skyrmions in noncentrosymmetric helimagnets. In these materials, the skyrmion lattice phase appears as a long-range-ordered, close-packed grid of nearly millimetre-level correlation length, while the size of a single skyrmion is 3–100 nm. This is a very challenging range of length scales (spanning 5 orders of magnitude from tens of nm to mm) for magnetic characterisation techniques, and, to date, extensive information on this fascinating, magnetically ordered state has remained elusive. In response, this work develops novel resonant elastic x-ray scattering (REXS) techniques, which allow the magnetic structure, including the long-range order and domain formation, as well as microscopic skyrmion parameters, to be measured across the full range of length scales. Most importantly, using circular dichroism in REXS, the internal structure of a given skyrmion, the topological winding number, and the skyrmion helicity angle can all be unambiguously determined. These new techniques are applicable to many materials systems, and allow us to retrieve information on modulated spin structures, multiferroic order, spin-density-waves, and other forms of topological magnetic order.

Chiral Building Blocks in Asymmetric Synthesis: Synthesis and Applications

by Elżbieta Wojaczyńska Jacek Wojaczyński

Chiral Building Blocks in Asymmetric Synthesis A comprehensive introduction to the important classes of chiral building blocks Chirality — the asymmetric quality found in certain chemical compounds — plays an essential role in our world: chiral compounds can be found in biology, pharmaceutical compounds, agrochemicals, and fragrances. The stereoselective preparation of these complex molecular constructions constitutes a challenge. To this end, modern asymmetric synthesis utilizes a variety of valuable and efficient reagents employed as chiral auxiliaries, metal complexes and organocatalysts in stereoselective catalysis, and enantiopure reactants termed as chiral building blocks. In Chiral Building Blocks in Asymmetric Synthesis, the achievements in the fields of preparation of and applications of chiral blocks are presented. In doing so, the book comprehensively discusses the important classes of these reactants as the key for the asymmetric synthesis of chiral molecules. As such, it is an indispensable resource about synthetic methods, as well as possible modifications and transformations of important classes of chiral compounds. It also highlights the importance of their use as reactants and auxiliaries in the preparation of more sophisticated molecules or supramolecular systems. In Chiral Building Blocks in Asymmetric Synthesis readers will also find: Organization according to the most important compound classes — e.g. amino acids, BINOL and its derivatives, terpenes, and others — with an emphasis on synthesis and application A focus on the use of chiral building blocks for the preparation of bioactive compounds and supramolecular assemblies Chiral Building Blocks in Asymmetric Synthesis is a useful reference for organic chemists, catalytic chemists, chemists in industry, medicinal chemists, pharmaceutical chemists, and the libraries that support them.
