{{Style P-Quote|“Several features in the Egyptian pyramids, especially the large one (that of Cheops), have long been a matter of surprise to scientific visitors; for instance, of having the sides of the square base exactly in the direction of the cardinal points of the compass — north, south, east, and west; of having the long tunnel leading from the side at the mouth obliquely down to the center of the pyramid, inclined under an angle exactly corresponding with the latitude under which the pyramid is placed, so that when looking from this center outward through this long hallway or tunnel, the polar star is always seen. This induced investigators to find more peculiarities having relation to astronomical data, and it was found that the pyramid abounded in these; for instance, the distance and size of the interior chambers, gangways, etc. At every step most curious relations were found, which certainly could not have been the result of accident. | {{Style P-Quote|“Several features in the Egyptian pyramids, especially the large one (that of Cheops), have long been a matter of surprise to scientific visitors; for instance, of having the sides of the square base exactly in the direction of the cardinal points of the compass — north, south, east, and west; of having the long tunnel leading from the side at the mouth obliquely down to the center of the pyramid, inclined under an angle exactly corresponding with the latitude under which the pyramid is placed, so that when looking from this center outward through this long hallway or tunnel, the polar star is always seen.

“The solar parallax means the angle under which the earth’s radius is seen from the sun. As we know the correct dimensions of our earth, it becomes a simple geometrical, or, rather, trigonometrical, question to find the distance: it is simply the problem to find the height of a very long triangle, of which the small base and opposite angle at the top are given. This angle at the top is the parallax-is, and if it be 8 seconds and 879 thousands, we have only to find the Sine of this angle, which will be to the Radius as the radius of the earth is to the distance of the sun. For very small angles the Sine is equal to the arc, and we have only to divide 8".879 (or, for simplicity sake, 8".88) into | “The solar parallax means the angle under which the earth’s radius is seen from the sun.
