Principal not Principle/Submissions for In Class Quiz

As many students have confounded the two words in the most recent blog posts, I thought I'd belabor  the meaning.  There are many possible definitions of principal.  For us, definition 6 is the most relevant one.

a person who takes a leading part in any activity, as a play; chief actor or doer.

In contrast, principle has really only one meaning, though they give three ways for providing that meaning.  A principle is an underlying rule or tenet.  In our class you have been exposed to the Efficiency principle, given in M&R.

It would be good to keep these straight in the future.
