I want to talk a little bit more about diffraction actually. And as a way of actually making a transition to our next topic, this may seem a little odd way – our next topic is sampling an interpolation. And going from diffraction to sampling interpolation may seem like a little odd of way going but it’s – there’s an interesting connection here that I want to exploit. The topic itself that I – the general areas of diffraction, and in particular what I want to talk about today, is interesting in itself and it does make actually for a nice link, so I want to talk about the problem of crystallography. ...
