It's not entirely out of the question, after all,
how many of you have the
knowledge of metalurgy to make any metal tool from say... the Bronze age,
or
Iron, or make gun powder, sure you know what's in it, but can you obtain
the
raw materials, and build the contraption that they used to make it?
<raises hand>
That's a silly question to ask on this list, isn't it?
