In 1932, during a talk at the International Congress of Mathematicians, Borsuk made a conjecture that every bounded set X in an n-dimensional Euclidean space can be divided into n+1 parts such that the diameter of each part is strictly smaller than the diameter of X.
Many partial results supported this conjecture. However, in 1993 counterexamples were discovered by Kahn and Kalai. In this talk we will introduce this well-known conjecture.
