Wow. What a great man, and educational value of this obit concerning X-ray crystallography to determine molecular structure/position is very interesting to me. I had worked at a repair level on a system known as ESCA, That would use an x-ray source and then bounce this x-ray off a parabolically ‘shaped’ crystal (Cut, so that at a molecular level a lattice of molecules would align) Allowing them to reflect the x-rays and thereby focus them to a spot to be analyzed; the x-rays wOULD then liberate electrons from that mysterious spot and then they would be swept into an Energy analyzer and from there one could determine an unknown surface contamination, kind of reversed in the process to find out the shape of the RNA
