We give thirty-two diverse proofs of a small mathematical gem—the fundamental Euler sum identity ζ(2,1) = ζ(3) = 8 ζ(2,1). We also discuss various generalizations for multiple harmonic (Euler) sums and some of their many connections, thereby illustrating both the wide variety of techniques fruitfully used to study such sums and the attraction of their study.

Elliptical galaxies are modelled as homeoidally striated Jacobi ellipsoids (Caimmi & Marmo 2005) where the peculiar velocity distribution is anisotropic, or equivalently as their adjoints configurations i.e. classical Jacobi ellipsoids of equal mass and axes, in real or imaginary rotation (Caimmi 2006). Reasons for the coincidence of bifurcation points from axisymmetric to triaxial configuratio...

The features associated with 30 childhood deaths from asthma in the period 1962-83 are reviewed. There was an annual death rate of 0.47/100 000 population at risk in the later part of this period in Avon county. Asthma deaths occurred in chronic severe sufferers at night and, although there was usually time for effective treatment, inadequate management probably contributed to the deaths, with ...
