  3. Asperity, defined as "unevenness of surface, roughness, ruggedness" (OED, from the Latin asper — "rough"), has implications (for example) in physics and in seismology. Smooth surfaces, even those polished to a mirror finish, are not truly smooth on an atomic scale. ...
  4. Roughness as of stone or weather; Something that is harsh and hard to endure; Harshness, as of temper; A part of a geological fault line that does not move. Earthquakes begin and end at asperities
  5. (Asperities) Microscopic projections on metal surfaces resulting from normal surface-finishing processes. Opposing asperities in sliding or rolling applications create friction, and can lead to metal welding and scoring. ...
  6. (ASPERITIES) microscopic pores that develop on a shaft seal’s elastomeric sealing lip at the point of contact with the shaft as a result of wear; asperities can be beneficial in that they help hold lubrication for the lip and facilitate a micro-pumping action that prevents leakage; also known as ...
