Quantum Methods with Mathematica

di Senin, Juni 25, 2012 Label: , , , ,
Ebook Download | Quantum Methods with Mathematica | Quantum methods with Mathematica is one of these concept books that combine a traditional subject with a new and powerfull way of presenting and analysing it. Quantum mechanics due to its mathematical nature is particuarly well suited for a Mathematica face-lift. I think the book is well suited for teaching undergraduate QM since you do things instead of just reading about them and that usually works with students. On a proffesional basis, it is not particularky well suited for heavy duty work but having said that to do such a thing would destroy its usefullness as a textbook. It can act as the starting point for more serious work with Mathematica and QM, and I would recommend it as a reference book or teaching aid with no hesitation.

Quantum theoretic machines: What is thought from the point of view ofphysics

Ebook Download | Quantum theoretic machines: What is thought from the point of view of physics | This is the fourth book by August Stern where he makes a compelling argument for the fundamental unity of logical and physical processes. As a result of this unified model he is able to then explore cognitive processes (logic, implication, learning) at the same level in which we explore fundamental processes of physics. Additionally, he points out that quantum theory and the associated quantum logic are not enough to model cognitive processes. He asserts these are necessary, but how do cognitive processes result from physical processes? He proposes a new matrix logic model that takes into account modern physical theory and cognitive theory. He observes that the physics behind quantum logic requires reversibility, but thought is not necessarily reversible. Simply said, how many of us can unthink a thought that we have already thought?

He also goes on to use this mathematical model to make predictions that are worth trying to explore. He gives explanations based on sound physics and the material is not for one who has a faint heart. One could wish that he would go a bit deeper into the details, but then the book would become a treatise on modern string theory and quantum field theory as well. I recommend a strong background in physics and logic to get a full appreciation of the concepts. In any case it is a fascinating read. I would recommend it to anyone interested in cognitive processes particularly modelling them, and if you have a willingness to do the mathematics then you will get more out of it.

Quantum leaps

di Minggu, Mei 20, 2012 Label: , , ,
Ebook Download | Quantum leaps | If one had to identify the basic theme of this book, one could say that it deals with the thoughts of people from varying backgrounds/professions on quantum theory and its implications. The author takes "quantum leaps" from one quantum sub-topic to another, all centering on these people's views on quantum theory: playwrights, authors (of novels, of new age books, etc.), artists, religious leaders (e.g., Dalai Lama), as well as the views of eminent physicists. The scientific explanations that are given throughout are generally quite clear, often including useful analogies. But, despite the fact that the book contains several discussions on various quantum phenomena, someone wanting to learn the basics of quantum theory should really look elsewhere. In addition to the science, the book also contains a fascinating agglomeration of snippets from the life of the author, including his interactions with some of the greatest luminaries in this field, as well as others. The writing style is clear, friendly, authoritative, relatively accessible and often quite captivating. Although anyone can read this book and learn quite a bit, it would likely be enjoyed the most by science buffs, especially those with a physics background, as well as those interested in the history of science.

Ebook Download | Maxwell's Demon 2: Entropy, Classical and Quantum Information, Computing | Maxwell's Demon 2 is one of the best books I've found in the field - the authors address key issues in a clear and engaging manner. This is an excellent and well-organized reference book and includes any number of original papers which are difficult to find through other sources. Highly recommended.

The Quantum Beat: Principles and Applications of Atomic Clocks

di Rabu, April 25, 2012 Label: , , , , , , ,
Ebook Download | The Quantum Beat: Principles and Applications of Atomic Clocks | There are excellent books discussing time at a level accessible for the general reader (e.g. Empires of Time, by Anthony Aveni). The Quantum Beat is the only one I've seen that gives a thorough discussion of the basics and then goes on to give an incredibly lucid discussion of all the minute details involved in making more and more accurate clocks. He elaborates on the pluses and minuses of each new development, from the sundial to the pendulum clock to the quartz crystal clock to the atomic clock. He also outlines the directions currently being pursued -- clocks based on a single atom held in an atom trap. The book will have special appeal to those who know about physics, crystals or engineering, and it should make fascinating reading for any educated layperson. Major was a key figure in the development of atomic clocks and has produced an exhilarating book describing their importance and the incredible technological efforts that went into their development.
