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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
Some thoughts on "Hermiones brain will be transfigured and kept frozen by Harry":
We know from Harrys first transfiguration lesson that transfigured living things undergo changes with time, which will kill said things. Harry knows this, and is thus likely to thing of deep-freezing the Hermione-diamond. Only he also plans to retransfigurate his fathers rock, and we know that one sustained transfiguration is a serious drain on his magic. Add to that the magical drain from having to cool the H-diamond and its thermal buffer, I think it unlikely that he did something of that sorts.
One way to circumvent the drain of the transfigured H-diamond would be to make it microscopically small, but he still would have to touch it regularly; given that its temperature should be in the cryogenic range, only touches with his wand would be feasible.
The only way I can think of to circumvent these problems would be to have others partake in the task, but that brings with it other problems.
Any thoughts which theories Harry tested with
Alternately, he might want people to believe he has transfigured his father's rock again, but not be actually planning to keep it transfigured, because he wants to carry the Hermione diamond and let people think it is the rock.
