... of a star. From the positions of a star on two or more occasions we obtain its apparent motion, also called the proper motion of the star.

... they sought to account for the phenomena which they observed. When once the method was changed, when once it had occurred to Kepler that, as it seemed to be impossible to account for the apparent motion of Mars by any theory of circular orbits, it might be worth while to try to ascertain by observation what its orbit really was, a few years of patient labour ...

... some first-class pitcher until they had hit the ball just once. They would be surprised to see how differently it looks. At a distance of only fifty feet from a man who can throw a ball like a streak of lightning, or with the same apparent motion, send it so slowly that one will think it is never going to reach him, who can curve it in or out, up or down, the question of hitting the ball at all becomes one of some doubt, to say nothing of "base hits."
