Wandering Among Newton Wonders
Donald Lynden-Bell
In the electromagnetic fields t^2 B = b(r/t), E = r x B/t trajectories of non-relativistic charged particles conserve (r-vt)^2. The transformation r'=r/t t'=1/t maps such trajector…

The Newton Wonder in Mechanics
Donald Lynden-Bell
Application of Newton's ideas from "Principia" gives many new results in mechanics. Here we explore the question ``What form of extra force will maintain the magnitude of a vector…

Rotation, Statistical Dynamics and Kinematics of Globular Clusters
Donald Lynden-Bell
Evolution with mass segregation and the evolution of the rotation of cores are both discussed for self-similar core collapse. Evolution with angular velocity proportional to the sq…
