Algorithmic Information Theory.pdf

Taken from Foreword: Turing’s deep 1937 paper made it clear that G¨odel’s astonishing earlier
results on arithmetic undecidability related in a very natural way to a class of computing automata, nonexistent at the time of Turing’s paper, but destined to appear only a few years later, subsequently to proliferate as the ubiquitous stored-program computer of today. The appearance of computers, and the involvement of a large scienti c community in elucidation of their properties and limitations, greatly enriched the line of thought opened by Turing. Turing’s distinction between computational problems was rawly binary: some were solvable by algorithms, others not. Later work, of which an attractive part is elegantly developed in the present volume, re ned this into a multiplicity of scales of computational difficulty, which is still developing as a fundamental theory of information and computation that plays much the same role in computer science that classical thermodynamics plays in physics: by de ning the outer limits of the possible, it prevents designers of algorithms from trying to create computational structures which provably do not exist. It is not surprising that such a thermodynamics of information should be as rich in philosophical consequence as thermodynamics itself.

Chemical Principles - Third Edition.pdf

Taken from PREFACE: This edition of Chemical Principles, like its predecessors, is designed to be used in a general university chemistry course which must provide both an overview of chemistry for nonspecialists and a sound foundation for later study for science or chemistry majors. Hence there are several survey chapters introducing different areas of chemistry, including inorganic, nuclear, organic, and biochemistry, and an attempt is made throughout the book to place chemistry in its historical and cultural setting. At the same time, the quantitative aspects of chemistry are presented in a manner consistent with their importance, in a way that will make it easy to build upon them in later courses. This is the first complete revision of Chemical Principles since the first edition was published in 1969. The authors have rethought and replanned the entire book, especially the first thirteen chapters, trying to make it a better pedagogical tool without losing the special viewpoints and flavor that made the earlier editions so successful. The history and the anecdotal asides that help to make the subject palatable have been retained, but they have been better segregated from the factual material for which a student will be held responsible.

Computational Cognitive Science.pdf

Human learning and reasoning is founded on multiple knowledge representations with different kinds of structures, such as trees, chains, dominance hierarchies, neighborhood graphs, and directed networks. This class uses probabilistic inference methods from machine learning and Bayesian statistics, operating over different kinds of structured representational systems, to explain how people’s domain knowledge can support a wide range of learning and reasoning tasks, and how these knowledge structures may themselves be learned from experience.
