    This is interesting in the context of the concept of "strength of
    materials". The Nobel Prize winning scientist who got the prize for
    his work on Bucky C said this was the strongest material in the
    universe. But there are varying definitions of strength. Strong at
    what temperature? Stength as in scratch-resistance in diamond? Yes,
    but where do diamonds rate if shatter-resistance is the measure of
    strength? (not a rhetorical question). Is jadeite more
    shatter-resistant than diamond?
