Informal Version of The Newton n-body Problem
The physical problem can be informally stated as:
- Given only the present positions and velocities of a group of celestial bodies, predict their motions for all future time and deduce them for all past time.
More precisely,
- Consider point masses, ..., in three-dimensional (physical) space. Suppose that the force of attraction experienced between each pair of particles is Newtonian. Then, if the initial positions in space and initial velocities are specified for every particle at some present instant, determine the position of each particle at every future (or past) moment of time.
In mathematical terms, this means to find a global solution of the initial value problem for the differential equations describing the -body problem.

Famous quotes containing the words informal, version, newton and/or problem:
“We as a nation need to be reeducated about the necessary and sufficient conditions for making human beings human. We need to be reeducated not as parentsbut as workers, neighbors, and friends; and as members of the organizations, committees, boardsand, especially, the informal networks that control our social institutions and thereby determine the conditions of life for our families and their children.”
—Urie Bronfenbrenner (b. 1917)
“Exercise is the yuppie version of bulimia.”
—Barbara Ehrenreich (b. 1941)
“I frame no hypotheses; for whatever is not deduced from the phenomena is to be called a hypothesis; and hypotheses, whether metaphysical or physical, whether of occult qualities or mechanical, have no place in experimental philosophy.”
—Isaac Newton (16421727)
“If we parents accept that problems are an essential part of lifes challenges, rather than reacting to every problem as if something has gone wrong with universe thats supposed to be perfect, we can demonstrate serenity and confidence in problem solving for our kids....By telling them that we know they have a problem and we know they can solve it, we can pass on a realistic attitude as well as empower our children with self-confidence and a sense of their own worth.”
—Barbara Coloroso (20th century)
