Time for a less serious matter.

In your textbooks you described some major benefits from seemingly minor innovations. For example, sticky notes or maybe the flat bottom on paper grocery bags.

What is your personal favorite "minor" innovation that has had a large impact on efficiency, and therefore, the economy?

• Some of your favorite books from your time away?

• I was anticipating your science fiction novel, any plans for that?

• How has your criticism, or taste, changed for the things you consume. Books, journalism, ice cream, alcohol, etc.?
