With intense lighting, the eye can constrict the pupil, yet allow enough light to reach the retina. The more the eye resembles a pinhole camera, the less it depends on focusing through the lens. [d] In other words, the degree of decoupling between focusing and convergence needed to visualize an autostereogram is reduced. This places less strain ...
The shapes of the miraged object are changing constantly and unpredictably. In order for a mock mirage to appear, the cooler air needs to be trapped below the inversion. Several inversion layers produce multiple pancake-like shapes. [3] It is possible that the solar anomaly mentioned in the Book of Joshua may have been an example of a mock ...

The fixed stars includes all the stars visible to the naked eye other than the Sun, as well as the faint band of the Milky Way.

Approximately 6,000 stars are visible to the naked ...
