Been away for a while, much depressing disease around me (on top of world climate in more than one sense)…
Now built a new (of sorts) angle #illusion, strifing for the simplest arrangement showing the illusion: https://michaelbach.de/ot/ang-obliqueSimple/

Academics' time:

“When asked about time off, Jordan replied: What do you mean? I work every weekend.”

This #ReceptioGate article is interesting because it considers wider issues for scholars, research, and academia: https://thecritic.co.uk/receptiogate-and-the-absolute-state-of-academia/

#phdchat does anyone have advice or resources on starting the introduction for the PhD? I'm doing it by publication, so I need a normal intro literatuatue review chapter & a second part to tie it all up. Feels like a mammoth task and my blank page is looking extremely daunting and empty 🤣. #academicchatter #phd #writing

DAGs, Golems, and Owls: Statistical Rethinking 2023 Lecture 1 (of 20). No hard work in this introductory lecture, just a conceptual outline and some dank memes. Lecture 2 later this week introduces Bayesian inference. https://www.youtube.com/watch?v=FdnMWdICdRs&list=PLDcUM9US4XdPz-KxHM4XHt7uUVGWWVSus&index=1

Another very interesting piece in this museum is the Mini-componium, a replica of the original Componium built by Diederich Nikolaus Winkel in 1821. This remarkable mechanical music instrument can vary the music it plays using a randomizing mechanism! In fact, the Componium creates endless variations on a theme by selecting randomly one of the 8 possible melodies every two measures.
In a sense, this is a very early example of

My periodic reminder that my book on the discrete Fourier transforms (incl. FFT, finite fields valued FT, representation theory, and more) is available for free. https://mathematical-tours.github.io/daft/

These music boxes were probably built at the end of the 19th century. An extra feature is the panorama of the horse race in the cabinet. By inserting a coin, the music is played and one can gamble on the winning horse. The machines were designed in such a way that the winning horse could not be predicted with any certainty.

I don't know how it works, but this is maybe one of the earliest random number generator! (2/2)

If you use frequentist statistics, you have to accept that 'no isolated experiment, however significant in itself, can suffice for the experimental demonstration of any natural phenomenon; for the "one chance in a million" will undoubtly occur, with no more or less than it's appropriate frequency, however surprised we may be that it should occur to us.' (Fisher). Replication is a core requirement of all frequentist statistics.

New paper provides a history of “voodoo science,” which discusses the controversy surrounding Vul et al.’s (2009) controversial article “Puzzlingly High Correlations in FMRI Studies of Emotion, Personality, and Social Cognition.”

There’s an absolutely astonishing story brewing in the medieval manuscripts world of a Potemkin Village scholarly institute built out of plagiarism and stock photos. I can scarcely do it justice except to link to Peter Kidd’s thorough deconstruction of #receptio #receptiogate

Ce sera bientôt les 10 ans de la disparition du regretté Aaron Swartz, le 11 janvier 2013 à l'âge de 26 ans.

Trop peu connu des élèves, étudiants et professeurs, je me suis permis d'y recopier ci-dessous le clip réalisée par France Culture en 2020 qui constitue une excellente entrée pour découvrir sa vie, son œuvre et ses luttes qui demeurent ô combien d'actualité.

Le 11 janvier prochain, parlons d'Aaron Swartz tout autour de nous !
