After a discussion of what ought to be meant by a local conservation law in General Relativity, we show physically that the energy density of the gravity field of static spherical systems can be deduced from natural axioms that we state. The result d

The orbits in the potentials ψ = − C z R − 2 + ζ ( R ) , ( ζ arbitrary) have integrals E , R 2 ϕ = h and h z + C ϕ = I . Thus the z -velocity is proportional to the number of turns made around the axis! The Poisson Bracket [ h , I ] is not z

The methods of exact optics are here extended to cover the design of lens and mirror systems. Power series are given for the shapes of both Schmidt corrector plates and their complementary almost spherical mirrors. Their off-axis images are analysed.

The collimation of jets by magnetic fields is shown to need external pressure which, due to the stabilised pinch effect, may be considerably less than the magnetic pressure at the core of the jet, but must then operate over a much larger area. This a

Franz Daniel Kahn was born in Nüremberg, Germany, on 13 May 1926. He came of a quite well–to–do German–Jewish family. His parents were Siegfried and Grete Kahn (née Mann) and his father was a successful manufacturer of children's toys. (The i

Prof. Leon Mestel has been an inspiration to many to study the role of magnetism in the Cosmos. To mark the occasion of his retin'ment from the University of Sussex after 43 years in astrophysics, several of his friends and former students decided to

The visible universe is a small perturbation on the material universe. Zwicky and Sinclair Smith in the 1930s gave evidence of invisible mass in the Coma and Virgo Clusters of Galaxies. Better optical data has only served to confound their critics an

Slowly rotating collapsing spherical shells have flat spaces inside and the inertial frames there rotate at omega_s(t) relative to infinity. As first shown by Lindblom & Brill the inertial axes within the shell rotate rigidly without time delays from
