South Asia A Three-Body Problem

A Trilinear Three-Body Problem

In this paper we present a simplified model of a three-body problem. Place three parallel lines in the plane. Place one mass on each of the lines and let their positions evolve according to Newton’s inverse square law of gravitation. We prove the KAM theory applies to our model and simulations are presented. We argue that this model provides an ideal, accessible entry point into the beautiful m...

Cerebrovascular disease in South Asia – Part I: A burning problem

Stroke is a non-communicable disease of increasing socioeconomic importance in ageing populations. According to the World Health Organization, stroke was the second most common cause of worldwide mortality. In South Asian countries demographic changes, urbanization and increased exposure to major stroke risk factors will fuel the stroke burden in the future. The prevalence of stroke in India is...

Solution of a Relativistic Three Body Problem

Starting from a relativistic s-wave scattering length model for the two particle input we construct an unambiguous, unitary solution of the relativistic three body problem given only the masses ma,mb,mc and the masses of the two body bound states μbc, μca, μab.

A Simple Charged Three-Body Problem

Dedicated to Paul Blanchard on the occasion of his sixtieth birthday. Abstract: The dynamics of a simple model of three charged bodies interacting under an inverse square electrostatic force is presented. The model may be viewed as an alternative to the pendulum, the standard model of a periodically forced and damped nonlinear oscillator.
