Review: The main result of this paper is the construction of a set P in the Euclidean space Ed with no less than (1.15)d elements, such that all angles determined by the triplets in P are acute, thus settling a long standing conjecture. For their elegant proof, the authors use a combination of geometry and probability theory. Some related results are established, and a number of interesting open questions is presented to the reader.
