All I need is George Takei.
“The advantage is it’s so much tougher, stronger, harder than glass. It provides better protection in more hostile environments—so it can withstand sand and rain erosion.”Either he's using words wrong for media points, or something in physics changed where hardness is no longer positively correlated with brittleness.

Hardness is a material's resistance to indentation and brittleness is breaking without significant plastic deformation. Something could be hard and brittle, or soft and brittle, or hard and not brittle, or soft and not brittle. Just depends on the material.

What materials are soft and brittle, or hard and elastic? I've never heard of any acting like that.

Haven't taken a materials class in a long time, but off the top of my head (and Googling to double check)Quote from: Essessen on November 22, 2015, 07:10:52 PMWhat materials are soft and brittleMost metals at extremely high temperatures (the Twin Towers demonstrated this viscoelasticity when their support structures failed due to high stress and temperature). Most woods are also fairly soft and brittle. Quoteor hard and elastic? I've never heard of any acting like that.Vulcanized rubber.

Even though hardness and brittleness aren't related, I mean.
