Author’s Note, Ch. 103

The final arc of HPMOR, chapters 104 through 120, will begin posting on February 15th, 2015, at 5PM Pacific Time, and finish on March 14th, 2015, at 9AM Pacific Time.  (The first draft of 104-120 is now complete at 88,310 words, most of it already edited, plus 2,300 words for Ch. 103.)


Oliver Habryka is coordinating wrap parties for HPMOR; please email him if you’re interested in having a wrap party in your city. There will at least be a major wrap party in Berkeley. Updates on this later.

If there is no specific wrap party in your city, then the fallback coordination point for meeting other HPMOR readers is any Pi Day celebration near you. (March 14th = 3.14 or Pi Day.  Yes, I know that Tau Day is cooler, but I’m not going to wait until June just for that.)  If a coordination time is required other than that of the Pi Day celebration, I declare it to be 6pm local time. I have no idea how well this will work, but it seems better than nothing.


I have some room for additional cameos. If you’ve created HPMOR fan art or music, and have not yet received a cameo, please email me at [email protected] with a description of which cameo names will work for you. Please make sure your email contains the word ‘cameo’, and include a link to the artwork or music for which you are to receive credit. Preference may be given to those whose allowable cameo names sound more like realistic Hogwarts students.


The Center for Applied Rationality is currently conducting their annual fundraising drive ending Jan 31st. As of now, people have donated $49,342 of the $120,000 CFAR needs to continue normal operations this year. Please consider donating to them! Without CFAR, there would be no organized attempts to actually develop, test, and teach the sorts of cognitive skills that I sometimes depict fictional characters as having.

For more on the latest developments at CFAR, please see their end-of-year update on CFAR in 2014.


Ch. 104 will post on February 15th, 2015, at 5pm Pacific Time.
