Seeing the World Through Breakage By Mark E. Eberhart, Published by Kawade Shobo, 2004, First Edition, ¥2200 The obi (sleeve) and cover have liquid stains and wrinkles (see photo 3). No stains are found on the main body of the book with the cover removed (photo 4). There's a reason things break. Just as Yotaro Hatanaka of Failure Engineering says, pursuing the reasons with "why, why" can step up technological science. This book is worth reading for development and design engineers.
