Scope Rules!

I was reminded of the power of scope (in the topic map sense) when I saw John D. Cook’s Quaternions in Paradise Lost.


See John’s post for the details but in summary, Kuiper’s Quaternions and Rotation Sequences quoted a passage from Milton that used the term quarterion.

Your search appliance and most if not all of the public search engines will happily return all uses of quarterion without distinction. (Yes, I am implying there is more than one meaning for quarterion. See John’s post for the details.)

In addition to distinguishing between usages in Milton and Kuiper, scope can cleanly separate terms by agency, activity, government or other distinctions.

Or you can simply wade through search glut.

Your call.
