    Many of the fundamental limits on information processing, from thermodynamics, relativity, and quantum mechanics, are only a few decades away. Novel physically motivated computing paradigms, such as reversible computing and quantum computing, may help in certain ways, but even they remain subject to some basic limits. One can arrive at several firm conclusions regarding upper bounds on the limits ... View full abstract»

    Simulations work in practice because they exploit higher-level organizing principles in nature. Good code writing requires faithfulness to these principles and the discipline not to exceed their limits of validity. An important exception is the use of simulation to search for new kinds of emergence. View full abstract»

    Using a conformational distance measure based on the changes in intramolecular atom distances, the authors show that a planar map can help visualize molecular dynamics trajectories efficiently such that conformational ensembles appear as well-separated point sets. The cluster analysis can then be used to automatically identify conformations View full abstract»

    The authors have created an object-oriented scripting interface to a mature density functional theory code. The interface gives users a high-level, flexible handle on the code without rewriting the underlying number-crunching code. The authors also discuss the design issues and advantages of homogeneous interfaces View full abstract»

    Patterns are well understood methodology for object-oriented software architecture, especially for business applications. Scientific programmers have generally avoided object-oriented approaches because of their heavy computational overhead, but the benefits of using patterns for scientific problems can outweigh their costs. This article introduces the concept of object oriented software patterns ... View full abstract»

    Recently, the Web consortium released the XML Schema specification, which is an elegant and powerful way of expressing an XML data instance's general object structure. Schema essentially replace data-type definitions and uses an XML syntax to specify object structure. For those familiar with object-oriented languages such as Java, Schema plays a similar role to classes. The sophisticated data stru... View full abstract»

    Mark Kac (1966) first posed what is now a famous question in mathematical physics: "Can you hear the shape of a drum?" In this article, the author discusses a related question concerning vibrating strings. Many musical instruments, including the guitar, piano, and violin, employ vibrating strings. The string vibrational modes are well known: they are just the usual standing waves. This problem nic... View full abstract»
