The Mindset of the Incoming College Freshmen 383

Beloit College has come out with its annual Mindset List of what the incoming class (of 2013) has always known and has never known. "For these students, ... the Green Giant has always been Shrek, not the big guy picking vegetables. They have never used a card catalog to find a book. ... Tattoos have always been very chic and highly visible. ... Rap music has always been mainstream. ... Except for the present incumbent, the President has never inhaled. ... Amateur radio operators have never needed to know Morse code."

I agree, redefine...but it seems easier to redefine it by fixing Avogadro's number and then saying that the mass of one mole of C12 divided by 12 equals one gram.

Maybe to a physicist/mathematician it seems inelegant to base the definition of mass on an arbitrary number (Avogadro's) rather than on a physical constant. But are we absolutely, positively sure that physical constants are constant throughout the space-time continuum and that we've got them exactly right?
