Thanks to @rachelphysics.bsky.social I watched "Steve" on Netflix last night. Excellent film.

Synesthetes claim sensory experiences, such as seeing color when reading or hearing a (black) number. โ€จBut how genuine are these reports and sensations? We introduce a rather direct measure of synesthetic perception: Synesthetesโ€™ pupils respond to evoked color as if it was real color #vision! ๐Ÿ‘๏ธ๐ŸŽจ๐Ÿงช

Same with scientific writing. Get a complete first draft quick but rough. Then refine. I wish I'd learned quicker!

I think with a lot of creative tasks it's great to get a version down and then improve it; aiming to be perfect first time is the enemy of success. In recording music I made progress when I split tracking, editing, mixing, mastering - standard; but if you try to mix too soon, it's disruptive.

This is a great thread. Also reminds me of my breakthrough experience in programming where I realized I enjoyed debugging. Once I got into that frame of mind it helped so much. I would write some code and try to predict what would go wrong. Then I got a boost if I was right, fix and repeat.

I think this is a *super* important paper - if this result can be replicated with other regions or tasks then this may come to form our core understanding of credit assignment signals in the neocortex!

Not central to the issue of LLMs but I am surprised that some academics of whatever persuasion are arguing that academic writing is "not supposed to read well". But it would explain a lot!

A week ago, we had an open conversation amongst senior academics in leadership roles and their use of LLMs (in both their leadership capacities and individually). Small group, not representative, but it already taught me a great deal about the diversity of perspectives (& their consequences). 1/

I was there for about 12 years. Had fun, made friends, learned a lot. And whenever I go back there I feel like I am coming home. Happy birthday UCL.

โ€œSome might be tempted to dismiss the Epstein files as just evidence of the extreme behaviour of a prolific sex offender.

But strip away the lewd and crude content, and they also reveal much about how patriarchy works day to day.โ€

I am surprised there's not more discussion about the security services' role in this. A lot of what's revealed in the Epstein files looks like subversion. While the authorities and government focus on people protesting fossil fuels or the war in Gaza, they don't seem alert to the greater threats.
