Discovery circumstances
Credit for the discovery of 886 Washingtonia has been given to George Peters of the US Naval Observatory, who was the first to report it. The object was, however, observed four days earlier by Margaret Harwood, who was advised not to report it as a new discovery because "it was inappropriate that a woman should be thrust into the limelight with such a claim".[2] The first woman to be credited with the discovery of a minor planet was Pelageya Fedorovna Shajn, eleven years later.

gollark: > First of all, we need to emphasize that the Pi Node software has not been released yet. So this section is offered more as an architectural design and as a request to solicit comments from the technical community. This software will be fully open source and it will also heavily depend on stellar-core which is also open source software, available here. This means that anyone in the community will be able to read, comment and propose improvements on it. Below are the Pi proposed changes to SCP to enable mining by individual devices. !!!
gollark: > Pioneer. A user of the Pi mobile app who is simply confirming that they are not a “robot” on a daily basis. This user validates their presence every time they sign in to the app. They can also open the app to request transactions (e.g. make a payment in Pi to another Pioneer)Hmm.
gollark: Presumably, if you run 1000000 emulators, they'll just exile you.
gollark: Ah, that makes sense then.
