In my article there has  not been to many words which I was unsure of the meaning due to the fact that the article is fairly entry level.  The authors really explain everything as simple as they can, the most difficult thing may just be understanding when they talk about measurement or temperatures and I have nothing to compare those units to.  I am also still trying to decide who this article is intended for because it is almost a written purposed idea but very simple and made to almost be a teaching piece.
