The next discussion thread is here.
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 chapter 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
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.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
How Magic Works, Some Facts, Inferences, Conclusions, and Speculations
The Facts:
The Speculations:
The source of magic has a certain limited number of permitted Spell to Effect associations on each power level. These associations are susceptible for expiration when no-one knows the spell anymore. High level associations were frozen in place by the Interdict of Merlin, but low level slots are still expiring, and whatever ritual the wizards use to create spells is merely triggering a garbage collect and conditional new spell insert.
Upon reception of the insert ritual, the Source of Magic scans the Wizard's mind, and performs an optimization algorithm on a set of existing spells to make a new spell which is close enough in some set of dimensions to what it thinks the Wizard wants, after which it associates the spell and effect. Therefore it would use thousands of years of existing infrastructure for making intelligent object effects.
In this scenario a wizard might be trying to create a spell for years, until a slot opens up that he will get to first, competing with everyone else trying to make spells.
Wizards, of course, not willing to accept the apparent randomness of this, have additional learned behaviors about creating spells, things they believe are required, most of which are not required and boil down to daydreaming about the effect you want and practice with the spell string and wand wave.
You don't distinguish your facts from your inferences well enough. Your list of "facts" seems to contains inferences like "Therefore time turners were limited after the invention of Equinoctal hours, in 127CE.", speculations like "Wizards seem to spend most of their time in pocket universes, otherwise you'd spot dragons and hogwarts trains on satellite imagery." and assumptions like "Children have unconscious magic, but not to the extent that OT Harry did."
