I agree with Tim on this one. A "diffract-o-meter" is a device for
measuring diffraction. Yes, at one time a Geiger counter attached to a
4- or 5-circle rotation stage was the only kind of "diffractometer", but
that is no reason to make the term exclusive to the original device.
As for Gerard's follow up, I remind him of the immortal wisdom of Jack
Handey:
"Maybe in order to understand mankind, we have to look at the word
itself. Basically, it's made up of two separate words — "mank" and
"ind." What do these words mean? It's a mystery, and that's why so is
mankind."
