As of this writing, Amazon.com ranks Wolfram's book number 18 in sales of all books. To put this in perspective, I checked the rank of the Feynman lectures (Addison-Wesley,1970), which was 2,003,and of Marc Kac's little masterpiece, Statistical Independence in Probability Analysis and Number Theory (Mathematical Assoc.of America,1959), which was 1,040,441 .Even if the sales figures were less impressive, a scientific book whose central premise is that the universe is an algorithm is bound to be of great interest to anyone concerned with computational science and engineering, and many other people as well. This issue of CiSE contains two reviews of A New Kind of Science. My purpose here is to make a few remarks about the directions this new science might take.","PeriodicalId":100659,"journal":{"name":"IMPACT of Computing in Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87686901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A second group would certainly be astronomy students and educators who need a desktop tool for exploring the mysteries of the cosmos. Many moons ago,I taught an introduction to astronomy course and would have been overjoyed to have had any of these programs available as a teaching tool.

{"title":"Understanding Quantum Computing: Quantum Computation and Quantum Information","authors":"G. Cybenko","doi":"10.1109/MCISE.2002.1014988","DOIUrl":"https://doi.org/10.1109/MCISE.2002.1014988","url":null,"abstract":"mechanics describes our world, as it seems to do at a very basic level. Moreover, the leading physicists of the 20th century continue to debate the true meaning and interpretation of things quantum, so it appears that this requisite intuition is highly personal. Fortunately, understanding quantum computation is a different matter. You can begin with a quantum-mechanical formalism based on familiar mathematics and treat most of how it applies to computation in a formal, almost axiomatic, way. This is different than profoundly understanding quantum mechanics but is, in my opinion, achievable with less effort and by more people. Michael Nielsen and Isaac Chuang have written an excellent book. It is readable and comprehensive; its closeto-conversational tone is unusual in a book on this subject. The authors write as if they were talking with readers, rather than lecturing at them, resulting in a pleasing style. However, the material is dense and the reader must be dedicated, motivated, and alert at all times. Just shy of 700 pages, Quantum Computation and Quantum Information covers several important developments in the subject through 2000, which is more than enough for someone who wants to get a solid grounding in quantum computing and its implications. The authors do not provide references to original sources as they develop material, deferring citations to a section at the end of each chapter. This leads to unnecessary suspense about who did what, and when. I referred to this section every few pages, just to satisfy my curiosity; folding the history discussion in with the idea presentation would have been more effective and consistent with the writing style. Quantum Computation and Quantum Information consists of three parts: fundamental concepts, quantum computation, and quantum information. Appendices cover some of the required background material. Because quantum mechanics is largely understandable in terms of probabilities and unitary operators, the half page devoted to unitary operators and two pages of background on basic probability send a clear message that the reader must have a significant mathematical background before tackling even the first part of this book. Part One, “Fundamental Concepts,” covers the basic ideas underlying quantum computing. This section uses the traditional notation, which is highly compact and subject specific. The text could be presented in the notation and terms of Hilbert space analysis, with which mathematicians and engineers are more familiar. Because my background is in mathematics, I must map the notation and logic into the functional analysis and matrix theory with which I am comfortable. For example, the notation and use of “bra” and “ket” seems to be the norm in this field, which is dominated by researchers trained in physics. A development of quantum computing using von Neumann’s language and notation would appeal to many trained in those terms. Part Two, “Quantum Computation,” builds on Lov Grover and","PeriodicalId":100659,"journal":{"name":"IMPACT of Computing in Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89123162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
