Lighthill agreed to give an invited lecture on'Biofluiddynamics of Balistiform Locomotion or "What triggers the trigger fishes?" However, 'the very sudden and drastic recent changes in China, leading to the disastrous deterioration in the state of the universities there, as well as to a serious destabilization of the position of Hong Kong (coupled with a worsening of its relations with Britain), have forced us to conclude that we must withdraw our formally given undertaking to attend the Congress'. |
