A talk about my new teaching book on Precision and Accuracy in Biological Crystallography, Diffraction, Scattering, Microscopies, and Spectroscopies.

The talk is based on the recent book, which provides the first comprehensive treatment of uncertainties in the structures determined by all relevant experimental methods; includes an improved set of database resources, governed by data deposition policies set by experts in the field; and highlights the need for new and improved methods which in turn will lead to important developments in research and equipment manufacturing.
