the article about the ultrasound scent research: writetobrain.com/olfactory
We Induced Smells With Ultrasound
We decided to try to stimulate the olfactory bulb with focused ultrasound. As far as we know, no one seems to have done this kind of stimulation before - even in animals.

Theorem of the day: Löb's theorem!

Löb proved that in Peano arithmetic, if you can prove that the proof of a proposition implies the proposition itself, then you can prove the proposition 🤪

So when I have a statement P, if I can prove the provability of P implies the truth of P, then I can prove P
The Gödel-Löb formula box bracket box p implies p close bracket implies box p

IKARUGA: Poster for IKARUGA. A top-down view of a graceful, birdlike aircraft against a soft gradient background. Geometry in the background assembles a vague HUD display, and text can be found throughout in several directions- “developed by TREASURE” “directed by HIROSHI IUCHI” “I WILL NOT DIE UNTIL I ACHIEVE SOMETHING. EVEN THOUGH THE IDEAL IS HIGH, I NEVER GIVE IN. THEREFORE, I NEVER DIE WITH REGRETS_” “I MAKE YOU ALIVE SO THAT YOU CAN WALK ALONG THE RIGHT WAY. BUT CAN’T YOU UNDERSTAND IT?” “IKARUGA” (in both Japanese and English)

I like to post Western artists influenced by Japanese woodblock to show how far-ranging this art form reached. Many artists tried to use painting techniques that looked like woodblock. UK artist Hilda Hechle (1886-1939) was one of these artists. Instead of yokai, she chose fairies and spirits.

Richard Lewontin was born OTD in 1929.

In scientific research we devote “exquisite attention … to methodological problems that can be solved, while the pretense is made that the ones that cannot be solved are really nothing to worry about."

Tired but happy to say this is out w @andreaeyleen.bsky.social: Are Neurocognitive Representations 'Small Cakes'? philsci-archive.pitt.edu/24834/

We analyse cog neuro theories showing how vicious regress, e.g. the homunculus fallacy, is (sadly) alive and well — and importantly how to avoid it. 1/
In order to understand cognition, we often recruit analogies as building blocks of theories to aid us in this quest. One such attempt, originating in folklore and alchemy, is the homunculus: a miniature human who resides in the skull and performs cognition. Perhaps surprisingly, this appears indistinguishable from the implicit proposal of many neurocognitive theories, including that of the 'cognitive map,' which proposes a representational substrate for episodic memories and navigational capacities. In such 'small cakes' cases, neurocognitive representations are assumed to be meaningful and about the world, though it is wholly unclear who is reading them, how they are interpreted, and how they come to mean what they do. We analyze the 'small cakes' problem in neurocognitive theories (including, but not limited to, the cognitive map) and find that such an approach a) causes infinite regress in the explanatory chain, requiring a human-in-the-loop to resolve, and b) results in a computationally inert account of representation, providing neither a function nor a mechanism. We caution against a 'small cakes' theoretical practice across computational cognitive modelling, neuroscience, and artificial intelligence, wherein the scientist inserts their (or other humans') cognition into models because otherwise the models neither perform as advertised, nor mean what they are purported to, without said 'cake insertion.' We argue that the solution is to tease apart explanandum and explanans for a given scientific investigation, with an eye towards avoiding van Rooij's (formal) or Ryle's (informal) infinite regresses.

"Cognitively speaking, we metabolize mistakes."

I've been reading William Wimsatt and he expresses a core component of my teaching philosophy better than I ever managed.
We are error-prone and error-tolerant—errors are unavoidable in the fabric of our lives, so we are well adapted to living with and learning from them. We learn more when things break down than when they work right. Cognitively speaking, we metabolize mistakes!
