It featured a unique solution for timing the drop, projecting a moving display onto a reflector sight that matched the apparent motion of the target at the right instant.
42.
When moving forward they still move relative to the constellations, which don't appear to move at all ( other than the apparent motion caused by the Earth's rotation ).
43.
Finally, there are sampling schemes that require real or apparent motion inside the camera ( scanning mirrors, rolling shutters ) that may result in incorrect rendering of image motion.
44.
Thus the event duration is determined by the time it takes the apparent motion of the lens in the sky to cover an angular distance \ theta _ E.
45.
These paradoxes are generally resolved by determining that the apparent motion of the circuit is actually deconstruction of the circuit followed by reconstruction of the circuit on a different path.
46.
After each image is captured, a computer measures the apparent motion of one or more stars within the imaged area and issues the appropriate corrections to the telescope's computerized mount.
47.
:By " flick book " do you mean a book with a slightly different illustration on each page, such that you see apparent motion when flipping through the pages rapidly?
48.
The apparent motion reverses because approximately four ( Earth ) days prior to perihelion, the angular speed of Mercury's orbit exactly equals its rotational velocity, so that the Sun's retrograde.
49.
The spacecraft body was spun at 2.2 rpm about a spin axis in the ecliptic plane and kept pointed about 12 degrees ahead of the Sun's apparent motion in celestial coordinates.
50.
This apparent motion or apparent movement is of great interest to researchers because the perceived movement does not derive strictly from the physical aspect of vision such as the stimulation caused by impingement on the retina.
