kind of tangential, but would an arbitrary wizard even know what bleach is?

If transfiguration can only result in non-magical substances, then science would help to transfigure to CBW agents - ending up too close for comfort. Wards cast in transfiguration classrooms and dormitories to detect intent to violate transfiguration rules would catch those, a wise expansive interpretation would catch the worst I can think of (critical mass of fissile material => will generate gas). The Hogwarts House system should force conformity and channel risk-taking into known paths. If failing to attempt homework would lose points, depression and... (read more)

1wedrifid8yI suppose the question would be "Is the typical magical cleaning potion harmful when dispersed in small amounts throughout the body?"
0pedanterrific8yThis question occurred to me partway through writing the great-grandparent, hence the 'or some other poison' clause. I'd expect naturally unpleasant chemicals to have lower lethal dosage requirements than, say, argon. (Although maybe the mapping involved interacts with molecules such that you'd be better off with mercury. Who knows?)

Harry Potter and the Methods of Rationality discussion thread, part 9

by Oscar_Cunningham 1 min read9th Sep 2011725 comments


(The HPMOR discussion thread after this one is here.)

The previous thread is over the 500-comment threshold, so let's start a new Harry Potter and the Methods of Rationality discussion thread.  This is the place to discuss Eliezer Yudkowsky's Harry Potter fanfic and anything related to it. The latest chapter as of 09/09/2011 is Ch. 77.

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: one, two, three, four, five, six, seven, eight.  The author page is the central location for information about updates and links to HPMOR-related goodies, and AdeleneDawner has kept an archive of Author's Notes.

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.
