A thoughtful and readable treatise on the process of innovative breakthroughs. Told in the case study method, the arguments are revealed and the points illustrated by concise retellings of several innovative breakthroughs such as Watson and Crick's identification of DNA and it's structure. Barbie's revolutionary re-make toy dolls, Frank Ghery's architecture, Guttenburg's printing press and Picasso's cubism are also held up to illustrate the theories. The myth of the lone genius illustrated by Edison's claim that genius is 10% inspiration and 90% perspiration is taken to task by this author. Rather, his vignettes illustrate that those who can make connections between idea spaces only loosely related by weak ties are the ones making the big breakthroughs. There's nothing really new under the sun it seems, just new ways to connect and combine ideas and processes. Several other contributing forces are described like the "law" of fitness, the law of the fit get rich, and so on. Maybe it's because I don't have a Harvard education but, I found some of the authors " laws" a bit complicated and confusing. I did however, love the vignettes and the overall description of the author's theory of the processes of innovative breakthroughs. His discussion of the the innovative necessity of connecting loose ties really got me thinking and was my favorite thread throughout the book. While I loved the book and it's ideas have stirred up my thought processes, I'm a bit skeptical that all of this represents a "new science of ideas". At the end of the day, if you are interested in innovation and how innovative leaps occur, this book should be well worth your time.
