What is the cue for stereopsis, and how is it generated by points in space at different depths? be certain to define crossed and uncrossed binocular disparities for objects along the optical axis. why is it a relative measure of depth? the work of julesz with random dot stereograms shows that (1) form need not be present in the monocular stimulus for stereopsis to take place and (2) stereopsis is impossible on the basis of point-by-point comparisons. how can both of these statements be true? what is the “matching noise problem” encountered in deriving depth information from random dot stereograms? how do cooperative algorithms potentially solve this problem?

The star betelgeuse is about 600 light-years away. if it explodes tonight, a. we'll know because debris from the explosion will rain down on us from space.b. we'll know it immediately because it will be brighter than the full moon in the sky.c. we won't know about it until 600 years from now.d. none of the above.

Holes drilled several kilometers into earth’s crust provide direct evidence about earth’s interior in the form of

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
