We know that Carter is pretty damn smart. Like really damn smart.
And we've seen from Jacob that blending with one of the Tok'ra gives a lot of knowledge. And we know that Carter occasionally gets flashes of Jolinars memories.
Is it possible that some of Carters scientific accomplishments and leaps of logic weren't entirely her own? That some of Jolinars memories subtly surfaced when she was attempting to figure things out, connecting the dots to things that she likely would have figured out but just a lot faster?
Not trying to detract from her intelligence at all, and we know they didn't truly blend together. But still, if she could get flashes of other memories and feelings, why not a little scientific knowledge as well?
And IF that did occur, how smarmy do you think Rodney would be and claiming he's the smartest human in the galaxy due to that?
