Goldberg, no longer Professor Zapp (a figment of J. Edgar Hoover's imagination), who constructed microdot know-how.

Buckland firmly but engagingly offers credits the place credits is due, within the strategy laying off mild at the conditions that ended in Goldberg's obscurity. the result's an illuminating tribute to a superb brain, and a desirable research of a very important interval within the heritage of data technology and know-how.

Where they overlap completely, the area of visible ink is minimal, the area of one dot. Where two dots overlap partially, the area of visible ink is larger and so that area will appear darker to the eye. When two dots are adjacent, not overlapping, the area of visible ink is maximal, the area of two dots, and so that small region will appear even darker. In this way, the rows of dots interact with each other in an unintended way determined by an accidental relationship in the alignment of the two sets of rows and, so, a second order periodic pattern emerges.

Goldberg, who was fond of hiking, was puzzled because photography did not seem to follow this law. He had noted that the exposure could be the same at the top of a mountain, where it was freezing, as it was for a meadow, below, where it was hot, if the light was bright in both places. The nineteenyear-old student suggested to Ostwald that the effects of heat and of light on chemical processes—thermochemical effects and photochemical effects, respectively—were in principle different. Ostwald thought that increased light merely enhanced the effects of increased temperature but expressed interest in Goldberg’s perception.
