The current theory of fundamental interactions among the quarks and leptons depends on eighteen parameters, which are a priori arbitrary. Were these parameters different, our world would be changed dramatically. By exploring the connection between these parameters and everyday phenomena we can better appreciate the challenges confronting contemporary particle physics. Until we can explain the origin of these parameters, we cannot say we truly understand why our everyda
