Edit: Directed to mathematicians ,I think this is a suitable time to open this question to know more about the creative mathematician Vaughan Jones Probably his students are ready for getting answers from them right now .
From Terry Tao's Blog, Vaughan Jones, who made fundamental contributions in operator algebras and knot theory (in particular developing a surprising connection between the two), died this week, aged 67.
Vaughan Jones was a very creative mathematician and he was arguably an extreme point in the convex hull of all mathematicians. He will very much be missed. And as a scientific family from MO we extend our sincere condolences to his family, friends and students.
And here is my big list/simple question to know more about this creative mathematician is:
Question: What do you like in the mathematics of Vaughan Jones? and how Vaughan Jones liked mathematics to be ?
Addendum: This part is directed to his students and his colleagues. As Jon Bannon suggested and pointed out in the comments, since Vaughan Jones was a very creative mathematician we may get from Vaughan Jones' students or by his colleagues the state of the art of his vision? And how Vaughan Jones saw what the applications of planar algebra in Quantum theory should be? The best example is the reformulation of Riemann hypothesis using planar algebra. More than that, how Vaughan Jones saw the connection between planar algebra and number theory should be used to solve biggest open problems in pure mathematics like Riemann hypothesis and irrationality measure of pi? Also from the point of view of Vaughan Jones does the expedition growth of mathematics need more development of knot theory and its connection with other area of mathematics and physics?
