Word Power

[Gregory Matthews]

Unobtainium:   Is an actual word used in American literature, but one that you have probably never used.  It has been in the language since the 1950s and it was featured in the 2009 movie Avatar.   In science, it is described as a material that would make space travel at a speed faster than the speed of light, possible.

For an interesting aspect of that word that I have not listed here, look it up.  It is on the Internet.  

NOTE:  Thanks to the December, 2017 issue of Scientific American (page 104) for a long paragraph on this word.
