Due to the inaccuracy of eye judgment and/or the error from the digitalized user interface (UI) of the microscope software, to obtain the highest precision in quantifying spot spacings of crystals, we normally measure a distance between higher order spots, and then divide it by n+1 (here, n is the number of spots between the two higher order spots). However, this method can induce errors if the Ewald sphere cuts the spot at an angle, or if there is a slight distortion of the diffraction pattern caused by the projector lens of the microscope. Therefore, it is important to know the systematic errors of the TEM and software by measuring diffraction patterns of “ideal” crystals. Electron microscopy (EM) managers often make mistakes in their managements. In fact, not only do the managers of EM labs need to master the relevant techniques and the knowledge of microscopes and materials, but also they should at least have some basic management skills, e.g. understand the organization and tips for running effective meetings as shown in Figure 3078a. Furthermore, the managers may also be interested in the comments given by Steve jobs in Figure 3078b.
