Description
When the original Pusztai & McGreevy RMC paper was published in 1988
we were at a turning point in the use of total scattering and pair
distribution functions (PDFs) in structural analysis. This talk examines
to what extent their paper was a watershed, transforming not just total
scattering analytical methods but also the way that we thought about
structure, and disordered structure in particular. I will first spend
some time explaining the time-line leading up to 1988 and will place the
Pusztai & McGreevy work in the context of what else was happening at the
time. This will set the scene for the second part of my talk where I
will discuss what followed, highlighting some of what has been achieved
since and providing a personal perspective as to what is still to be
attempted.
