Such a Morning plot
A mathematician suddenly and without explanation, at the height of his career, decides to withdraw from public life. The professor moves into an old, rusty train car, which is isolated in a hilly landscape. As he becomes further withdrawn into himself, his gaze seems to sharpen. Through the train windows he sees everything, down to the smallest detail: a shiny thread of a spider's web, every rustling leaf, every flower. He also sees the landscape passing by, as if he were sitting in a moving train, as if time were speeding up. Initially he tries to keep a grip on things by measuring them and by capturing them in mathematical formulas, but in the end nothing can be measured anymore.
