. This diagram illustrates how the definition of a pixel depends on the users distance from the viewing surface (paper or screen). The image depicts the user looking at two planes, one 28 inches (71 cm) from the user, the second 140 inches (3.5 m) from the user. An expanding cone is projected from the user's eye onto each plane. Where the cone strikes the first plane, the projected pixel is .28 mm high. Where the cone strikes the second plane, the projected pixel is 1.4mm high. Return to image.

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...
