A radical and optimistic view of the future course of human development from the bestselling author of How to Create a Mind and The Age of Spiritual Machines who Bill Gates calls “the best person I know at predicting the future of artificial intelligence”
For over three decades, Ray Kurzweil has been one of the most respected and provocative advocates of the role of technology in our future. In his classic The Age of Spiritual Machines, he argued that computers would soon rival the full range of human intelligence at its best. Now he examines the next step in this inexorable evolutionary process: the union of human and machine, in which the knowledge and skills embedded in our brains will be combined with the vastly greater capacity, speed, and knowledge-sharing ability of our creations.

A Huffington Post Definitive Tech Book of 2013
Artificial Intelligence helps choose what books you buy, what movies you see, and even who you date. It puts the "smart" in your smartphone and soon it will drive your car. It makes most of the trades on Wall Street, and controls vital energy, water, and transportation infrastructure. But Artificial Intelligence can also threaten our existence.
In as little as a decade, AI could match and then surpass human intelligence. Corporations and government agencies are pouring billions into achieving AI's Holy Grail—human-level intelligence. Once AI has attained it, scientists argue, it will have survival drives much like our own. We may be forced to compete with a rival more cunning, more powerful, and more alien than we can imagine.
Through profiles of tech visionaries, industry watchdogs, and groundbreaking AI systems, Our Final Invention explores the perils of the heedless pursuit of advanced AI. Until now, human intelligence has had no rival. Can we coexist with beings whose intelligence dwarfs our own? And will they allow us to?
First, there is a brief overview of the history and development of the spectroscope. This is followed by a short introduction to the theory of stellar spectra. The final parts of this section provide details of the necessary reference spectra required for instrument testing and spectral comparison. It concludes with a chapter covering the various types of spectroscopes available to the amateur.
Next, there is a series of "How to..." sections. These cover all aspects of setting up and using various types of commercially available and home-built spectroscopes. Transmission gratings are covered first, and then more complex models, all the way to the sophisticated Littrow design.
The final part of Astronomical Spectroscopy for Amateurs is about practical spectroscope design and construction. It contains a collection of detailed instructions covering the design and building of three different types of spectroscope, along with the necessary design theory (with minimal math). Developing an instrument in simple steps from the basic grating spectroscope, using standard "off the shelf" adaptors, the author describes how to build spectroscopes equal in performance to the better commercial units, constructed using basic hand tools for a fraction of the cost!
This is the only up-to-date practical spectroscopy book available to amateurs. For the first time, it also brings together an invaluable user knowledge base – a collection of observing, analyzing, and processing hints and tips that will allow the amateur to build up and develop important skills in preparing scientifically acceptable spectral data, which can make a valuable contribution to ProAm (professional/amateur) projects. It covers in detail all aspects of the design, construction techniques, testing, calibrating, and using a spectroscope – enough detail to enable the average amateur astronomer to successfully build and use his own spectroscope for a fraction of the current commercial cost.
This book is an ideal complement to Robinson’s Spectroscopy: the Key to the Stars (Springer 2007) and Martin’s Spectroscopic Atlas of Bright Stars (Springer, due 2009). Together, the three books form a complete package for all amateur astronomers who are interested in practical spectroscopy.
As Professor Chris Kitchin said, "If optical spectroscopy had not been invented then fully 75 percent of all astronomical knowledge would be unknown today, and yet the subject itself receives scant attention in astronomical texts." Olivier Thizy (of Shelyak Instruments, the builder of the LiHiResIII commercial spectroscope) writes on an Internet forum; "What is missing is tutorial books and "how to" books with amateur equipment? I believe spectroscopy is in general moving from builders to users (as CCD cameras did in the 1990's)... ...literature is following but slowly."
This is the practical spectroscopy book that amateur astronomers have been waiting for!
Ray Kurzweil is arguably today’s most influential—and often controversial—futurist. In How to Create a Mind, Kurzweil presents a provocative exploration of the most important project in human-machine civilization—reverse engineering the brain to understand precisely how it works and using that knowledge to create even more intelligent machines.
Kurzweil discusses how the brain functions, how the mind emerges from the brain, and the implications of vastly increasing the powers of our intelligence in addressing the world’s problems. He thoughtfully examines emotional and moral intelligence and the origins of consciousness and envisions the radical possibilities of our merging with the intelligent technology we are creating.
Certain to be one of the most widely discussed and debated science books of the year, How to Create a Mind is sure to take its place alongside Kurzweil’s previous classics which include Fantastic Voyage: Live Long Enough to Live Forever and The Age of Spiritual Machines.

Jeff Hawkins, the man who created the PalmPilot, Treo smart phone, and other handheld devices, has reshaped our relationship to computers. Now he stands ready to revolutionize both neuroscience and computing in one stroke, with a new understanding of intelligence itself.
Hawkins develops a powerful theory of how the human brain works, explaining why computers are not intelligent and how, based on this new theory, we can finally build intelligent machines.
The brain is not a computer, but a memory system that stores experiences in a way that reflects the true structure of the world, remembering sequences of events and their nested relationships and making predictions based on those memories. It is this memory-prediction system that forms the basis of intelligence, perception, creativity, and even consciousness.
In an engaging style that will captivate audiences from the merely curious to the professional scientist, Hawkins shows how a clear understanding of how the brain works will make it possible for us to build intelligent machines, in silicon, that will exceed our human ability in surprising ways.
Written with acclaimed science writer Sandra Blakeslee, On Intelligence promises to completely transfigure the possibilities of the technology age. It is a landmark book in its scope and clarity.

Video decoding is an example of an application domain with increasing computational requirements every new generation. This is due, on the one hand, to the trend towards high quality video systems (high definition and frame rate, 3D displays, etc) that results in a continuous increase in the amount of data that has to be processed in real-time. On the other hand, there is the requirement to maintain high compression efficiency which is only possible with video codes like H.264/AVC that use advanced coding techniques.
In this book, the parallelization of H.264/AVC decoding is presented as a case study of parallel programming. H.264/AVC decoding is an example of a complex application with many levels of dependencies, different kernels, and irregular data structures. The book presents a detailed methodology for parallelization of this type of applications. It begins with a description of the algorithm, an analysis of the data dependencies and an evaluation of the different parallelization strategies. Then the design and implementation of a novel parallelization approach is presented that is scalable to many core architectures. Experimental results on different parallel architectures are discussed in detail. Finally, an outlook is given on parallelization opportunities in the upcoming HEVC standard.
