DESCRIPTION:Title: Blue skies in the four body problem\n\nSuppose that a 2 
 freedom Hamiltonian system has a saddle focus equilibrium solution. Moreov
 er\, assume that the attached stable/unstable manifolds intersect transver
 sally in the energy level. In this case classic theorems of Henrard and De
 vaney describe the rich dynamics near the intersection. I'll recall the hi
 story of these homoclinic phenomena going back to the numerical work of Da
 rwin\, Moulton\, and Stromgren in the early Twentieth Century. Then I'll d
 iscuss some more recent work on the equilateral restricted four body probl
 em.\n
