We study spacecraft motion near a binary asteroid by means of theoretical and computational tools from geometric mechanics and dynamical systems. We model the system assuming that one of the asteroids is a rigid body (ellipsoid) and the other a sphere. In particular, we are interested in finding periodic and quasi-periodic orbits for the spacecraft near the asteroid pair that are suitable for o...

We investigate the spectrum of elementary particles and fields arising from the superposition of string configurations weighted according to their entropy in the string phase space. We find that this superposition describes a universe with a physical content phenomenologically compatible with the experimental observations and measurements. Masses and couplings are determined as functions of the...
