Promotional Information

This book fills an important niche for the undergraduate by providing a well-organized, well-written introduction to a subject usually addressed in books for graduate students. Its problem-based approach to programming in Maple and Java, using common physics problems in a multitude of areas such as mechanisms, electromagnetism, and relativity, is very effective method of instruction. -- Gregory Moses, University of Wisconsin-Madison This easy-to-follow book is novel in being a hands-on workbook rather than a standard textbook. Importantly, it integrates scientific examples with a discussion of

About the Author

Reviews

One of Choice's Outstanding Academic Titles for 2005 "Essential... Rubin Landau offers a practical introduction to the world of scientific computing or numerical analysis. He introduces not only the concepts of numerical analysis, but also more importantly the tools that can be used to perform scientific computing... The presentation is particularly useful because real-life examples with real code and results are included."--Choice "Not only is [this book] an invaluable learning text and an essential reference for students of mathematics, engineering, physics, and other sciences, but it is also a consummate model for future textbooks in computational science and engineering courses."--Mathematical Reviews "The contents can be taught in lab-based courses at the undergraduate level. Much of the material covered is usually addressed in separate books. Therefore, the book is also suitable for independent study by graduate students and professional who wish to learn one or more of the languages in a comprehensive way with the emphasis kept on problem-solving."--Frits Agterberg, Computers and Geosciences "The colloquial and tutorial approach might help alleviate the many practical problems associated with incorporating computational applications into a more traditional lecture environment. The text provides many concrete and programming examples in action and illustrates how much you can accomplish with a few well-chosen tools... [S]tudents impressed with the text's workbook style and reference book quality will add it to their bookshelves and return to it often."--Michael Jay Schillaci, IEEE Computing in Science and Engineering
