I use this blog to gather information and thoughts about invention and innovation, the subjects I've been teaching at Stanford University Continuing Studies Program since 2005.
The current course is The Greatest Innovations of Silicon Valley (Fall '14).
Our book "Scalable Innovation" is now available on Amazon http://www.amazon.com/Scalable-Innovation-Inventors-Entrepreneurs-Professionals/dp/1466590971/

marital stability = frequency of lovemaking - frequency of quarrels
