Posts: 848 Thanks: 0 All you have to do is set up a mirror a decent distance away from you, and you can see half the sphere by alternately looking directly at the sphere and looking through the mirror at it :P ! Using two mirrors, and placing them behind and two each side of the sphere, you can see all of it at once :P :P !

I'm not so sure. I think you need 3 mirrors to be able to see the whole sphere.

Also, yay! Somebody agrees with my answer to the original problem.
