One example of a human-nonhuman process that Zylinska talks about is the search for dark matter. I had very recently attended a lecture describing the locating of possible dark matter, something that leaves a gravitational imprint but cannot be detected via any other known method. Scientist use advanced telescope and other advanced astronomical measurements, (that I unfortunately did not catch) to view an immensely detailed view of a snippet of the universe. By using the human eye, we can look at galaxy shapes and other patterns in galaxy formation to hypothesize the where about of dark matter. Then trading it back off to the computer for finer details in terms of the actual amount and the coordinates of the possible whereabouts. This process of non-human to human to non-human then back again to human filters through the visual information that is deemed unnecessary to hone in on the invisible.
