The theory of computing provides computer science with concepts, models, and formalisms for reasoning about both the resources needed to carry out computations and the efficiency of the computations that use these resources. It provides tools to measure the difficulty of combinatorial problems both absolutely and in comparison with other...

Progress in biology is dependent on the ability to observe, measure, and model the behavior of organisms at multiple levels of abstraction, from the microscopic to the macroscopic. There has been a tremendous growth recently in the techniques to probe the structure and workings of cellular and organ-level mechanisms. Significant advances have...

There are many anecdotes, articles, and books about optimizing in specific scenarios. Sometimes, these include hard numbers; if so, it’s usually for hardware that is several years old. Often, the discussion is very specific, such as optimizing memory copies for a specific chip, and the...

In the fall of 2004, at a popular software conference I realized how all major component vendors were advertising their ASP.NET products using a new word—Ajax. Only a few weeks later, a brand new module in my popular ASP.NET master class made its debut—using Ajax to improve the user experience. At its core, Ajax is a little...
