SUMMARY:It's all About Matter\, Physics Department Colloquium\, Young-
 Kee Kim \, U Chicago
DESCRIPTION:Subatomic-particle research has made enormous progress in 
 the 20th Century by looking inside matter at deeper and deeper levels.
   It is as if we were peeling the layers of an onion in the hopes of f
 inding more basic rules for the structure of nature. Although the conc
 ept of the ultimate building blocks of matter has been modified in sev
 eral essential respects in the last century\, Democritus’s idea rema
 ins at the foundation of modern science. Great experiments of the 20th
  century have led to the discovery of ever-smaller entities that make 
 up what were once thought to be indivisible particles.  Moreover\, the
  theory of the very small has been shown to be intimately connected to
  the largest scales imaginable – cosmology and the beginnings of the
  Universe.  Despite these considerable successes\, the current theory 
 has within it the seeds of its own demise and is predicted to break do
 wn when probed at even smaller scales. One of such examples is the ori
 gin of mass of fundamental particles. We have achieved a beautiful and
  profound understanding of how fundamental particles acquire their mas
 s\, but the mass values remain deeply mysterious. In addition\, we lea
 rned that ordinary matter supplies only a small fraction of mass in th
 e Universe. We continue to peel away at the more hidden layers of trut
 h with the hope of discovering a more elegant and complete theory.  Bu
 t as is the case with the onion\, we must wonder whether there will ev
 er emerge an ultimate layer where the peeling must stop.
