I'm prepping for @fens.org Forum in Barcelona.
To improve my Spanish I'm reading Hola and watching Almodavar Films which covers a nice spectra.
As for the science I've a poster w Rebecca Brady on our mathematical model of Audio-Visual integration.
On the Comms side I've a poster about Funny Brains.

@stevenstrogatz.com I was showing my undergraduates your lovely 1988 Romeo & Juliet differential equations paper. Which is an excellent way of demonstrating novel and enjoyable applications of maths.
A possible popular update could changing it to the two protagonists of Heated Rivalry.

The @neuromatch.bsky.social compneuro summer school is excellent.
And I recommend it to anyone interested in maths, neuroscience, modelling and/or machine learning.

I’m a bit late to reading this article by @marcusghosh.bsky.social in the @thetransmitter.bsky.social
I really enjoyed it.
I’m definitely pro toy mathematical models, I believe they can be informative and push research forward.

There is definitely nothing weird about Musk repeating β€œI’m pro-human”. Some of my best friends are human and I would definitely want AI to keep them in a safe in a future human sanctuary.
Nothing weird at all.

Thanks James and feel free to use them.
I really enjoy the face recognition one.
All kids should learn how to do dot products and ICA.
I'll be adding accessible code of kids that will link with the leaving cert computer science course over the next while.

Each year, #mathsweek is a few weeks after the equinox. So, this year some mathematicians were given the job of studying time. They started out by counting seconds. However, they quickly got bored and after 24 hours they called it a day. @diasdunsink.bsky.social

Check out our new multisensory decision study!
We tackle a decades-old Q: does faster detection of bimodal targets come from a race or co-activation between modalities? And also a vital, orthogonal Q: is it one decision process or two?
A1: co-activation
A2: two!
