Cut by a line the union of given disjoint disks in the plane so that both sides of the line contain many intact disks. At least how many intact disks can we leave in either side? It is proved that there is a family of infinitely many disjoint disks in the plane for which every line has a side that c
Let F n denote a family of disjoint n balls in R d (d 2), and let \*=\*(F n ) denote the ratio (maximum radius)Γ(minimum radius) among the balls in F n . We prove that (1) there is a unit vector uΓ such that every line parallel to uΓ intersects at most O(-(1+log \*) n log n) balls of F n , and (2) t
