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 Principles of Invention and Innovation (Summer '17).
Our book "Scalable Innovation" is now available on Amazon http://www.amazon.com/Scalable-Innovation-Inventors-Entrepreneurs-Professionals/dp/1466590971/
In a 2001 story, the New York Times reported that there were 23,068 reported pickpocketing incidents in the city in 1990, amounting to nearly $10 million in losses. Five years later, the number of reported incidents had fallen by half, and by the turn of the millennium, there were less than 5,000. Today, the NYPD doesn't even maintain individual numbers on pickpocketing. "It's hardly a problem anymore," says a department spokesperson.
