Pi in the Sky

Roger Jerome Phlutter, for whose absurd surname I offer no defense other than it is genuine, was, at the time of the events of this story, a hard-working clerk in the office of the Cole Observatory.
He was a young man of no particular brilliance, although he performed his daily tasks assiduously and efficiently, studied the calculus at home for one hour every evening, and hoped some day to become a chief astronomer of some important observatory.
Nevertheless, our narration of the events of late March in the year 1999 must begin with Roger Phlutter for the good and sufficient reason that he, of all men on earth, was the first observer of the stellar aberration.
Meet Roger Phlutter.
Tall, rather pale from spending too much time indoors, thickish, shell-rimmed glasses, dark hair close-cropped in the style of the nineteen nineties, dressed neither particularly well nor badly, smokes cigarettes rather excessively…
At a quarter to five that afternoon, Roger was engaged in two simultaneous operations. One was examining, in a blink-microscope, a photographic plate taken late the previous night of a section in Gemini. The other was considering whether or not, on the three dollars remaining of his pay from last week, he dared phone Elsie and ask her to go somewhere with him.
Every normal young man has undoubtedly, at some time or other, shared with Roger Phlutter his second occupation, but not everyone has operated or understands the operation of a blink-microscope. So let us raise our eyes from Elsie to Gemini.
A blink-mike provides accommodation for two photographic plates taken of the same section of sky hut at different times. These plates are carefully juxtaposed and the operator may alternately focus his vision, through the eyepiece, first upon one and then upon the other, by means of a shutter. If the plates arc identical, the operation of the shutter reveals nothing, but if one of the dots on the second plate differs from the position it occupied on the first, it will call attention to itself by seeming to jump back and forth as the shutter is manipulated.
