But beyond that, this movie was great!
In engineering, fiction, or thought experiments, unobtainium is a humorous concept for any extremely rare, costly, or physically impossible material needed to fulfill a given design for a given application. The properties of any particular unobtainium depend on the intended use. For example, a pulley made of unobtainium might be massless and frictionless. However, if used in a nuclear rocket, unobtainium would be light, strong at high temperatures, and resistant to radiation damage.
The word unobtainium is derived from unobtainable + -ium (the suffix for a number of metal elements).
I too laughed at the ridiculous name they gave it but then heard it mentioned in other places.
Unless of course you knew this and just thought it was lame that Cameron wrote that in there heh.
