Friction Matters: Resistance Is a Feature, Not a Bug

On with Kara Swisher

Friction gets an bad rap, according Jennifer Vail. As a tribologist, she studies interacting surfaces in relative motion, and she’s worked on everything from aerospace materials to syringes to dog food. Her new book, Friction: A Biography, explores the science of rubbing surfaces, the history of lubrication, and why “frictionless” is a dangerous fantasy. 


Kara and Jennifer unpack everything from Roman chariot “pit stops” to ball bearings and how tiny tweaks in texture and lubricant chemistry can save massive amounts of energy. They end with a discussion of behavioral friction (the kind tech companies want to get rid of) and Kara makes the case for “good friction” in tech, work, and relationships.
