Title: The Illumination Problem
OM 215
ABSTRACT: A search light is a right angle in the plane.
Four search lights are situated at four arbitrary points
in the plane. Is it always possible to turn the
search lights about their vertices so that the whole
plane will be illuminated entirely?. Some
generalizations of this problem will be considered at
the colloquium talk. Students are encouraged to attend.
