Abstract

I plan to discuss some of the results and unsolved problems relating to: Steinhaus' lattice problem or simultaneous tiling problem: Is there a set in the plane which meets each isometric copy of Z^2 in exactly one point? and Sierpinski's 2 point problem: Is there a set in the plane which meet each straight line in exactly two points?
