Structure & Interpretation of Computer Programs has had a dramatic impact on computer science curricula over the past decade This long-awaited revision contains changes throughout the text There are new implementations of most of the major programming systems in the book including the interpreters & compilers & the authors have incorporated many small changes that reflect their experience teaching the course at MIT since the first edition was published A new theme has been introduced that emphasizes the central role played by different approaches to dealing with time in computational models objects with state concurrent programming functional programming & lazy evaluation & nondeterministic programming There are new example sections on higher-order procedures in graphics & on applications of stream processing in numerical programming & many new exercises In addition all the programs have been reworked to run in any Scheme implementation that adheres to the IEEE standard
