Reading posts by foreigners about Brazil, I get the impression that you're not aware of the full extent of the accusations against Sen. Flávio Bolsonaro, or of the available evidence of his corruption.
So I'd like to kindly invite you to really get to know Flávio. A thread 🧵🇧🇷

One of the single best essays written about Brazilian politics this year
This is very good

SOMEONE BUILT A WEBSITE WHERE THE SPEED OF LIGHT IS 5 KM/H AND YOU CAN WALK THROUGH IT.
it's called Relativity Park → rivendell.dmitrybrant.com/re…
open the tab. you are standing in a 3D park. WASD to walk. mouse to look.
nothing weird yet. just a park.
then you start walking faster.
and the faster you move, the more the park starts lying to your eyes.
because in this world, light does not move at 300,000 km per second. it moves at 5 km/h. a brisk walk.
so all the Einstein stuff that usually hides at impossible speeds suddenly happens while you press W.
the world ahead of you turns blue. the world behind you turns red. lengths in front of you start to squeeze. your watch and the world clock stop matching.
you can toggle each weird effect one by one:
> L for light-travel delay
> G for aberration and contraction
> C for Doppler color
> B for relativistic beaming
not a textbook. special relativity turned into a tiny walkable world.
built by Dmitry Brant, a lead Android engineer at Wikimedia Foundation. also the guy behind DiskDigger. open source. 607 upvotes on Hacker News last week.
open tab.
press W.
watch the universe bend.

Paper is out! 📑
"Transcranial magnetic vs intracranial electric stimulation: a direct comparison of their effects via scalp EEG recordings"
brainstimjrnl.com/article/S1…
Highlights:
• IES evokes higher signal-to-noise EEG responses than TMS.
• IES responses are larger, slower, and lead to cortical suppression.
• TMS elicits faster recurrent waves, with no suppression during wake.
• Both TMS and IES converge to similar patterns during sleep.

Finally published:
“Explosive neural networks via higher-order interactions in curved statistical manifolds”

Enhancing the capabilities of recurrent neural networks by deforming their geometry!
reply to the pseudo-science polemic is now out, identifying the clash between computational and structural paradigms underlying the whole matter, as well as intrinsic vs extrinsic accounts of consciousness
very happy and honored to have been a part of this!
Consciousness or pseudo-consciousness? A clash of two paradigms

Published in Nature Neuroscience today!

Our paper is finally out! Can we compare subjective experiences (qualia) between individuals? We propose that unsupervised alignment, the search for optimal mapping between similarity structures of qualia, is a key to this fundamental question.

[Deadline extended to Mar 14, 2025!] Recently, we noticed that the announcement of our summer school has not reached as widely as we hoped for. Not sure what's the best media... Anyways, if you could help us, please spread the words to any social media, email list, etc...
[Application Open!] 2025 Oct 5-17 in Italy. Summer school on Qualia Structure + Integrated Information Theory. Deadline 2025 Feb 28. Please see docs.google.com/document/d/1… for the financial support, program and application details! RT please!

New preprint out with @theBjornErik and Giulio Tononi. arxiv.org/abs/2412.21111
Some questions we address:
– What is the relationship between phenomenal experiences and stimuli that trigger them, i.e., how does perception fit in to IIT?
– What does IIT have to say about meaning, and what does this imply for the concepts of reference & representation in IIT?
– How does all of this connect to evolution, development, & learning?
– How does our account contrast with those that invoke the language of information processing / encoding to characterize perception?
Thanks to all the folks in the lab who contributed in countless discussions!

Hi, David. I am the Findlay you refer to. Thank you for your thoughts. There is a lot here, and X will not let me pay for the space to leave a full reply, since I am a new user (just here for this)! I'll send you a preprint or two. But here is some brief context, for others. 👇
thanks to @mttgrs @theBjornErik and @jemhendren unwavering work, an IIT wiki is now online! really great resource to learn about all its concepts and algorithms👇
For anyone interested in IIT, we developed iit.wiki to give a vanilla-to-technical overview of the whole framework (mostly thanks to the phenomenal work of @theBjornErik and @jemhendren). Please help us improve it by submitting questions and feedback.

Passando pra divulgar o lançamento desse livro que sintetiza a reflexão crítica de dissidentes do MST (e MTST) sobre sua experiência e o nosso tempo, no próximo sábado em São Paulo. Pra quem quer encarar o que é militar hoje, imperdível.
looking forward to reading this! 👇
Are theories of consciousness (ToCs) about the same thing?
Yes✅
To show this, we unify 6 ToCs, arguing that they each capture unique aspects of temporal phenomenology. Putting experience first, helps collective theorizing. Out now🧵:
