Feynman Diagrams (IMAGE)
Caption
Max Planck researchers have used Feynman diagrams to formulate what they need to do to create a complete picture from incomplete data. In the simplest case, known as the Wiener filter, you conclude point A from point B (left-hand image, a). It is more complex but also more reliable to reconstruct A if you consider information from points C and D in combination (b). The scientists use a loop to describe how the uncertainty surrounding point B affects point A (c). Depending on the conditions, the rules for reconstructing data can be very complex (right-hand image).
