An extremely useful reference for professional, engineer or student on many different areas. This handy handbook includes tables, illustrations, formulas, and when needed brief and concise description of fundamentals and examples.I used it as a student, and many years later I still use it as a quick reference in my job. I am an Electronics Engineer, but I work as an Instrumentation, Automation and Process Safety and Control for the Process Industries. As a result I have been involved with Chemical and Mechanical Engineering issues in a day to day basic. This handy reference has proven most useful and time saving when in need of an specific formula, table, or shortcut.Its size make it useful too when you travel for work.
