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 114, and also, as a special case due to the exceptionally close posting times, chapter 115.
There is 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.)
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Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).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.
Yeah, this is one of those solutions that, had I been writing, I would have ruled as not actually workable. Takes too long, Voldemort or a Death Eater sees the threads and breaks them on general principles, nanotubes don't actually have enough tensile strength to reasonably slice up everybody at once consistently, and so forth. I pretty much filed any tactical violence plan under "not practical".
Still, not my story. It's not out of keeping with the rest of the stuff in HPMOR.
High odds that Voldemort escaped. He's been extraordinarily hammy this whole time, and he called all the Death Eaters together, killed or crippled a few, and then explained his evil scheme to the hero before giving him a countdown to his inevitable death, while leaving him armed. It seems very plausible that Tom Riddle was tired of Lord Voldemort, and decided to retire him via dramatic massacre. Why make his new body a snaky freak-show, after all?
On the pedantic nitpicker trivia side of things, you don't have a tank of "oxyacetelene". An oxy-acetylene rig uses a tank of oxygen, and a tank of acetylene. But Harry is probably not a welder, and neither are the Weasely twins, so nobody involved was equipped to notice the problem.
The volume of the transfiguration makes it negligibly quick; nanotubes have the highest tensile strength of any material and they were not lone tubes, but braided; I'm fairly sure spotting a braided nanowire in the dark is nearly impossible; and the tension transfiguration is what made the slicing consistent. How exactly is it not practical?
