Paul Cooper has done an outstanding job of detailing the diverse world of explosives engineering. Included is sufficient detail to get a researcher new to a topic started and enough background to help an 'old timer' teach. The last five chapters on Engineering Applications is an unequalled summary of the use and analysis of the practice of explosives engineering. I use this book as my 'carry along' reference for both R&D testing and systems analysis of explosive devices.
