They probably did give their instructors ulcers. I wonder if that is a pre-condition for wanting to get your Phd in Physics.

Alright folks, Here is a little modification:> 'Burp'....excuse me; I just took Alka-Seltzer!
A solid elastic rubber ball is a perfect sphere of radius r in free
space. A solid homogeneous spherical massive run away planet also in
free space has a spherical cavity formed at its center. The cavity is
much larger than the ball and has vacuum in it. The ball is now
transported to the center of the planet. Its radius now is
(A) > r
(B) < r
(C) = r
(now come on....don't ask me to define free space)
How did you guys ever take any exam without giving your instructor
ulcers?!
