This book provides students with an introduction to Fortran 90, one of the most powerful and flexible programming languages for scientific computation available today. The author shows how using computers and Fortran 90 it is possible to tackle and solve a wide range of problems as they might be encountered in engineering or in the physical sciences. Following a brief introduction to computing in general, the author presents a thorough guide to problem-solving and algorithm design using pseudo-code to develop an understanding of the steps that need to be taken to solve a particular problem. Subsequent chapters introduce the main features of Fortran 90 motivated by particular ideas and tasks that are typically found in science and engineering

A thorough guide to problem-solving and algorithm design using pseudo-code * Each chapter includes at least two complete programming applications which become progressively more challenging * Students new to computing will find the wide range of problems both accessible and relevant to their other studies * Includes a brief introduction to computing in general
