Question -   What is the strongest material in the world?
-------------------------------------------------------------
The answer depends a bit upon what you mean be "strongest". In the 
usual sense of the term "strongest" is taken to mean "hardest", in 
which case, diamond is the strongest of natural occurring materials.

Hi Anne,

The word "Strongest" needs qualifying. If what you mean is
strongest in compression, then even ordinary concrete is high
on the list. I suspect, however, that you are wondering what
is the strongest material when subjected to tension. In that
case, carbon nanotubes are probably the strongest materials
yet discovered. Although not a practical material for
everyday use (yet), this material has been tested to be at
least 50 times stronger in tension than steel. Carbon
nanotubes are long tubular shaped molecules of carbon, far,
far smaller in diameter than a human hair, yet can be as long
as several millimeters in length. A concise explanation is
available here: http://en.wikipedia.org/wiki/Carbon_nanotube

Bob Wilson.
