three-body

Even with an easier non-living system, Newton thought the three-body problem deterministically intractable, and so it remains without special assumptions.

Even the generalized three-body system can only be predicted in the 'near term'. mynym: Although many seem to imagine that the theory of natural selection is the equivalent of the theory of gravity, it doesn't seem to predict much.

Introductory physics classes learn there is no solution to the three-body problem, and the atmosphere is a lot more complicated than just three asteroids cycling around each other in space.

On Thursday, the Legg report will be published along with... 2009

The time evolution of the three-body problem is still a subject of active research in celestial mechanics and that is practically the simplest system we can thinkof.

In the traditional three-body doctrine, however, it is the other two forms of embodiment that preach.

Euler also studied continuum mechanics, lunar theory with Clairaut, the three-body problem, elasticity, acoustics, the wave theory of light, hydraulics, and music.

Euler, Leonhard 2009

If we have a three-body system, we can conceptually divide it into three two-body systems, and knowing the forces that would operate in the two-body systems were they isolated, we can deduce what the forces are that are operating in the three-body system.

John Stuart Mill Wilson, Fred 2007

Henri Poincare was a favorite to win the prize, and he submitted an essay that demonstrated the stability of planetary motions in the three-body problem (actually the “restricted” problem, in which one test body moves in the gravitational field generated by two others).

What he ended up proving was the opposite of his original claim — three-body orbits were not stable at all.

In 1885, a mathematical competition was announced in honor of the 60th birthday of King Oscar II of Sweden, and the three-body problem was one of the questions.
