The information about the difference is included in Mary's education. That is what was given.
Are you surprised all the time? If the change in Mary's mental state is what Mary expected it to be, then there is no surprise.
How do you know?
Isn't a mind that knows every fact about a process itself an analogous physical process?
This is how this question comes to resemble POAT. Some people read it as a logic puzzle, and say that Mary's knowing what it's like to see red was given in the premise. Others read it as an engineering problem, and think about how human brains actually work.
That treatment of the POAT is flawed. The question that matter is whether there is relative motion between the air and the plane. A horizontally tethered plane in a wind tunnel would rise. The treadmill is just a fancy tether.
What? That's the best treatment of the question I've seen yet, and seems to account for every possible angle. This makes no sense:
The plane in the thought experiment is not in a wind tunnel.
Treated realistically, the treadmill should not have any tethering ability, fancy or otherwise. Which interpretation of the problem were you going with?
A plane can move air over its own airfoils. Or why not make it a truck on a treadmill?
By the way, you may not agree with my analysis of qualia (and if so, tell me), but I hope that the way this thread derailed is at least some indication of why I think the question needed dissolving after all. As with several other topics, the answer may be obvious to many, but people tend to disagree about which is the obvious answer (or worse, have a difficult time even figuring out whether their answer agrees or disagrees with someone else's).
I definitely welcome the series, though I have not finished it yet, and will need more time to digest it in any case.
