Harry Potter and the Methods of Rationality discussion thread, part 21, chapters 91 & 92

NancyLebovitz

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapters 91 & 92 . The previous thread has passed 500 comments.

There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)

The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17,18,19,20.

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.

Figuring out the way the brain connects to the body and reconnecting all the individual nerve connections makes the challenge much harder.

I study neuroscience. You may know something I don't, but I think body transplants would be a lot easier than resurrecting the dead, as long as you save the first few sections of the spinal chord as well - repairing broken spinal chords, albeit imperfectly, is somewhat in the realm of current technology. If we're talking magic, I don't think spinal chord injuries would even be a big deal.

Edit: never mind everything written below about the freezing

I was quite disappointed when Harry just froze her like that. The rapidly expanding ice will destroy much of her data - in real cryonics you pump 'em full of antifreeze to prevent this. Even if he revives her, she might not quite be the same now. He should have transfigured her head into a small crystalline structure and later found some way to securely maintain the spell (and if no one knows he did it, the pesky authorities won't try to take off the spell).

Definitely. There's been some news around this: HEAVEN: The head anastomosis venture Project outline for the first human head transplantation with spinal linkage (GEMINI.

I don't think think I know anything you don't. It's possible I just have a dated conception of how hard it is to repair severed nerves.

Harry didn't freeze her. He cooled her to 5° Celsius, equivalent to 41° Fahrenheit and well above the freezing point.
