The book is "Improving almost anything - Ideas and essays" and can be found on Amazon, but I think the Wiley description [0] does it more justice. His writing is accessible and full of witticisms such as "When Murphy speaks, listen" (referring to Murphy or Sod's Law). His works are good building blocks for all kinds of research.
