Query: Yes, 60 years later we are still working hard on vortices   With the excitement generated by this year's Nobel Prize in physics, here I
give a brief critical review of current vortex dynamics research activity,
using a recent book as the background material. Two directions in which major
progresses can be expected are selected: the role of vortex-phonon interaction
in low temperature superfluid turbulence and the complete integration of
topological method into vortex dynamics. In addition, I would like to call
attention to 3 important experiments which have not been fully appreciated in
the past: 1) the measurement of vorticity quantization via Magnus force done in
Britain; 2) the extensive study of Josephson-Anderson relation carried out in
USA; and 3) the direct measurement of Magnus force in superconductors performed
in Sweden. They will play an important role in the further development of the
field.
