Once the data was added we realized that many of these data types were probably unkown or misunderstood by our visitors.

Consequently a new :definitions” section was added. We took this project further and added 28 subject areas. The subject areas were intended for three general user types or experience levels, Student, Beginner, Intermediate. Datatables , puictures, and illustrations were added to support these subjects. The subjects were loosely intended to hit the high points of a 4-year program of study in Chemistry.
