DESCRIPTION:These talks will limn twistor theory: &nbsp\;a theory that wil
 l work in curved spacetimes and in arbitrary dimensions\, even infinite\, 
 but stick to the basic principles.&nbsp\;\nTools to focus on will be the a
 nalysis of massless particles in the style of David Mumford and Roger Penr
 ose and the structure of null geodesics after Ted Newman and Ray Sachs\, u
 sing the language of the limits of Roger Penrose.
