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 next course is Principles of Invention and Innovation (Summer '14).
Our book "Scalable Innovation" is now available on Amazon http://www.amazon.com/Scalable-Innovation-Inventors-Entrepreneurs-Professionals/dp/1466590971/

According to Robyn Dawes*, as cited in Daniel Kahneman's book Thinking Fast and Slow,
marital stability = frequency of lovemaking - frequency of quarrels
