The noble court of Materials Science, where King Kelvin rules with an iron... coefficient. Engineers worship at this altar of physical properties, treating each material constant like royalty. Meanwhile, the rest of us peasants are just trying to remember which one means "how well it conducts heat" versus "how much it bends before snapping." Notice how "replies from crush" sits at the round table? That's because getting a text back has roughly the same probability as correctly calculating thermal conductivity on your first try. Zero.
