DESCRIPTION:This series of webinars was planned in commemoration of George
  Batchelor's promotion of the field of fluid mechanics in all its varied a
 spects and applications. In rounding off the series\, I shall first commen
 t on how much George Batchelor himself would have enjoyed the 15 brilliant
  presentations that we have heard. It is good to know that our subject is 
 flourishing so vigorously with the young talent that has been so evident t
 hrough these presentations. I shall use the short time available to me to 
 discuss three questions that I touched on in my JFM Perspectives paper "So
 me topological aspects of fluid dynamics":\n(i) How are corner eddies affe
 cted by increasing the Reynolds number of the remote forcing?\n(ii) How do
 es a sheet of air enter through the free-surface cusp in a tightly control
 led situation?\n(iii) How can knotted or linked magnetic flux tubes most e
 fficiently jump from one minimum-energy state to another?
