Do we understand (powder) X-ray diffraction?

X-ray diffraction is an extremely successful technique for determining the atomic-scale structure of matter and has been used for more than a century. Not all appears to be well, however. Based upon the observation that surprisingly complete powder diffraction patterns can be obtained using samples with very few crystallites, Dr. Paul Fewster has challenged the conventional interpretation of X-ray diffraction and has recently published "A new theory for X-ray diffraction” [Acta Cryst. A70 (2014) 257].
The goal of this mini-symposium is to understand and discuss this new theory. Dr Paul Fewster will explain his ideas, while several other speakers will present closely related topics. There will be ample time for discussion.
