ABSTRACT
This chapter focuses on how a star, a galaxy, and a cell relate to each other, and especially, how data measurements are transformed into visual representation and how they actively participate in the formation of theories. The development of different microscopic techniques has informed our knowledge of cells' structures and functions at all times. Super-resolution microscopy was developed to make visible intracellular structures that are increasingly smaller than the limits of optical resolution, that is., at this point in time structures that are below 10 nanometers small instead of 200 nanometers. However, localization microscopy is a drastic example for this insight. In order to obtain an image with the highest spatial resolution in localization microscopy, the cell has to be chemically fixed. Images in science are not only illustrations of work done by other means to communicate scientific results; they can also be regarded as tools for experimental discovery in their own right.
