Newton's Laws of Graduation

1. First Law: A grad student in procastination tends to stay in procastination unless an external force is applied to it.
2. Second Law: The age, a, of a doctoral process is directly proportional to the flexibility, f, given by the advisor and inversely proportional to the student’s motivation m.
3. Third Law: For every action towards graduation there is an equal and opposite distraction.
