The gravitational three-body problem is one of the oldest conundrums in astronomy and classical mechanics, and yet it is becoming central to explaining astrophysical phenomena. I will first focus on gravitational wave astrophysics, and show how hierarchical triples formed in stellar clusters can trigger the merger of black hole, black hole-neutron star, and black hole-white dwarf binaries. Then I will present a novel method to model common envelope evolution in population synthesis and N-body codes, which was based on a simple perturbed 2-body problem.
