- tunap 10y agoEven better: https://en.wikipedia.org/wiki/Hardness https://en.wikipedia.org/wiki/Hardness I read an enlightening discussion on HN a few months back about "hardness". I was under the impression professional scientists/researchers do not use the generic terms "hard" or "hardness". Outside of marketing, I presume they would employ concise measurements like ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity.
