He didn’t know then that these same questions were being asked in numerous other

Gravity is such a pesky thing. It prevents us from doing all sorts of wonderful things. Such as floating through the air like a balloon, traveling into orbit without paying an ugly cost in delta V, and being morbidly obese but still light on your feet like Baron Vladimir Harkonnen. By the same token, it would also be incredibly useful to be able to create gravity on command.

Molecular Dynamics. A MD simulation generates a sequence of points in phase space connected in time The result is a trajectory of all particles in the system as a function of time Time averages and other properties can be calculated from this trajectory Motion of the system through phase space is governed by Hamiltonian equations of motion : r˙.
