I learned to respect friction, as a phenomenon with many nuances, when I was a graduate student. One day, while teaching a problem session in elementary mechanics, I unwisely invented a new problem to ...

This paper gives a review of mathematical results of existence and uniqueness of solutions to problems of linear elasticity involving friction. Static, steady sliding and quasi-static problems are ...

Static zaps when you climb out of a car are more than a minor annoyance; they are a tiny physics lesson delivered straight to your fingertips. With a few simple changes to how you exit, what you wear, ...
