	I wonder if you're referring to recent essays (Nature and/or 
Physics Today) by Frank Wilczek?  He has recently been writing about the 
origin of mass, and seems to find it striking that matter (protons and 
other hadrons) are so heavy although their presumed constituents are 
massless gluons and nearly massless light quarks.  It is possible that 
such speculations will lead Wilczek to a calculation that will win him 
another Nobel, but until such time I shall decline to attempt to explain 
them (pick your own antecedent for "them").
