vi. The intensities and resolutions at the diffraction focus of optical systems with rotationally symmetric minimum-variance aberration functions as well as functions with slight variations from this shape and a prescribed fixed maximum deviation value at the edge of the exit pupil are calculated for circular and annular exit pupils. The results for the intensity at the diffraction focus obtained either by numerical integration of the diffraction integral or by using the Maréchal formula show that the maxima of these intensities are achieved for optical systems with wave aberration functions of minimum variance, thus verifying the Maréchal criterion. The resolutions (first zeros of the intensities in the radial direction) at this diffraction focus are also presented.

Comparison of the replica Empire State Building in Las Vegas to original in New York City, from street level angle and side view (replica on the left of each pair). The replica is optimized to look like the original from the POV of foot traffic by forced foreshortening of the top floors.

xxii. The Great Unconformity is a geologic feature where two adjacent layers of rock were not formed one after another in the earth's development. The lower layer was always at a high point, undergoing erosion, and in this case for an extended time, even in geological terms. The Great Unconformity is visible in different places in the U.S.. It is one of many unconformities that exist around the world and one of the largest. At Frenchman Mountain in Nevada, there is a gap of about 1.2 billion years where the rock jumps from 500 million years old to 1.7 billion years old. In the Grand Canyon, the clearly visible discontinuity represents a time gap that varies from about 250 million years to 1.2 billion years. The Great Unconformity's missing 1.2 billion years represents about 25% of the earth's history. (Wikipedia)
