I don't know why this question comes up all the time or why it is so 
difficult to grasp, but just to put it to rest...

1) open image file (p1)
2) duplicate image (p2)
3) apply Levels adjustment to endpoints to p1 (input levels)
4) apply curve adjust to p2 with same input levels at the end points
5) Calculate -> Subtract p1 from p2
6) Check histogram and note that you have a mean of zero and a std. 
deviation of zero
7) Correctly conclude that Levels and Curve adjustments are identical 
in outcome.

Since they both have the same algorithm options it should have been 
obvious that they do the same thing.

now I think that should settle it...
