"This category [science fiction] excludes rocket ships that make U-turns, serpent men of Neptune that lust after human maidens, and stories by authors who flunked their Boy Scout merit badge tests in descriptive astronomy."

| Stereoscopic Vernier and Cube | ||
| A means of photographing in depth. |
As far as I know, the moulage method of making a copy of tire tracks is still in use.
| “When did the police abandon the
moulage method of making casts?”
“Five years ago,” said Wohl. “We now photograph impressions with stereoscopic cameras. Impressions on fibrous surfaces are photographed in relief with the aid of the parallel light beam.” “I know all that,” Graham told him. “But why is that method now used?” “Because it’s handier, and absolutely accurate. It has been used ever since they found a way to measure stereoscopic depth by means of... heck!’’ — he risked a swift glance at his passenger, and concluded — “the Dakin stereoscopic vernier.” |

The picture was projected in three dimensions.
“Cute!” he murmured.
Finding the now-dead scientist’s
original and somewhat crude model of
his vernier, Wohl amused himself by
projecting its standard stereoscopic cube
upon a small screen. He twiddled the
micrometer focusing screw that controlled the cube’s perspective, made the
geometrical skeleton flat enough to appear almost two-dimensional, then deep
enough to resemble an apparently endless tunnel.
