Explanation:

The science fiction short story "Exhalation" by Ted Chiang based on the Second law of thermodynamics. This scientific short story is epistolary, meaning that it is written in the form of documents.

And in it, the narrator was seen to dissect his own brain, to find out that it is functions from the movement of air in between the gold leaves. The rate at which the air passes depends on the atmospheric pressure, thus the different  computing manners of different people. He also discovers that the same air pressure below and above ground will lead to the cessation of time itself.

The excerpt from the text shows the scene where he decided to dissect on his own brain. But this description is nowhere near emotional or personal. Instead, it is more businesslike. He acted as if this is a normal business procedure and not something that is personally close to you.
