The origins of the Journal of Fluid Mechanics , of which the first volume was published in 1956, are discussed, with reference to editorial correspondence during the early years of the Journal . This paper is based on a lecture given at the colloquiu

The vortex ring is a fundamental phenomenon of fluid dynamics, recognized since the seminal investigations of Helmholtz ( 1 ) and Kelvin ( 2 ). Its familiar manifestation as a “smoke ring” in air derives from the fact that both smoke and vorticit

Recent work has shown that a M\"obius strip soap film rendered unstable by deforming its frame changes topology to that of a disk through a 'neck-pinching' boundary singularity. This behavior is unlike that of the catenoid, which transitions to two d

Turbulence remains one of the oldest and most challenging research problems in both pure and applied science; recognition of the phenomenon can be traced back to Leonardo da Vinci who introduced th...

A variety of physical and biological systems exhibit dynamical behaviour that has some explicit or implicit topological features. Here, the term ‘topological’ is meant to convey the idea of structures, e.g. physical knots, links or braids, that h

One of the simplest geometries in which to study fluid flow between two soap films connected by a Plateau border is provided by a catenoid with a secondary film at its narrowest point. Dynamic variations in the spacing between the two rings supportin

Helicity is, like energy, a quadratic invariant of the Euler equations of ideal fluid flow, although, unlike energy, it is not sign definite. In physical terms, it represents the degree of linkage of the vortex lines of a flow, conserved when conditi
