Taking a look at #LDPC codes again, and observing that it amounts to solving 3-SAT, but with soft decision inputs. This means no algorithm for decoding them will be fast and exact at the same time
@pettter has his thesis defense on order-preserving graph grammars today!
Today in the lab: measuring the instrument's moment of inertia along each cardinal axis using a trifilar pendulum. About 1% accuracy, and within theoretical bounds! #tothemoon2020
Entering day three of the vacuum test. All motors still spinning happily at 3600 RPM or so. Should be interesting to see how crusty the bearings are at the end of this..
Also transplanted the data logging to the raspberry pi to free up my laptop. Looks like we'll collect 50 MB of data in total over the week
The science #limericks are multiplying!
I don't know the lower left moon language, but I'll try to translate the Swedish one:
'An inventor living in some backwater
wrote to the patent bureau last quarter

made vacuum-dried H2O,
you only need to add water!"'
Scholar Social is a microblogging platform for researchers, grad students, librarians, archivists, undergrads, academically inclined high schoolers, educators of all levels, journal editors, research assistants, professors, administrators—anyone involved in academia who is willing to engage with others respectfully.
We strive to be a safe space for queer people and other minorities, recognizing that there can only be academic freedom where the existence and validity of interlocutors' identities is taken as axiomatic.
"An academic microblog that you can be proud to put on the last slide of a presentation at a conference"
(Participation is, of course, optional)
Scholar Social features a monthly "official" journal club, in which we try to read and comment on a paper of interest.
Any user of Scholar Social can suggest an article by sending the DOI by direct message to @email@example.com and one will be chosen by random lottery on the last day of the month. We ask that you only submit articles that are from *outside* your own field of study to try to ensure that the papers we read are accessible and interesting to non-experts.
