New Books in Science, Technology, and Society Jennifer Vail, "Friction: A Biography" (Harvard UP, 2026)
Feb 3, 2026
Jennifer Vail, a tribologist who studies friction across scales, explains why this everyday force shaped technology and culture. She traces ancient lubricants to modern nanoscale solutions. Short segments cover friction in fluids, space, the body, and climate impacts. There’s fun physics about curling and why bridging macro and nano laws remains unsolved.

How Tribology Got Its Name
- The term "tribology" was coined in the 1960s to name a new interdisciplinary science about rubbing and wear.
- Peter Jost and the OED editor chose a Greek root (tribos) to give the field scientific legitimacy.
Da Vinci As Founding Tribologist
- Leonardo da Vinci experimentally quantified friction and sketched tribometers centuries before formal publication.
- His unpublished work was later rediscovered and paralleled by Guillaume Amontons' published experiments.
Classical Laws And Their Limits
- Classical laws: friction ∝ normal force and is independent of apparent contact area.
- The velocity-independence 'law' often breaks at high speeds or with fluids, so it is not absolute.
