I read it on TikTok that every cat needs a Switch 2 to be truly happy.
I bought mine one and he didn’t even care. Don’t fall for this, guys!

Hi United Statesians Friends,
This is what’s happening in Brazil right now: the tyrant that tried to take power by force after losing the elections is being trialled.
This is how you deal with a coup attempt in a healthy democracy, not by reelecting the tyrant…
(My face of joy for reference)

With a Labour Party like this, who even needs the Tories?
Do not call labour a “left wing party” in front of me, it won’t end up well.

Hi Bsky friends!
I wrote another rant, I mean, article for Medium!
This time is about how we need more freedom in academia, but not in the "freedom of speech" sense.
We need more free time to think and develop bold new ideas
Please read and share it if you enjoy!

I sometimes wonder in how many FBI, Interpol, etc watchlists I am because of the Kilo Degree Survey.
At some point, writing so much about KiDS in github, overleaf, gdocs, etc must put you in a lot of unwanted lists for different governments. 😂

Google reminded me of this photo I took in 2015 in an event about science and art in London (something about light and dark matter, can’t remember).
I had just moved to the UK for my PhD and this event was super inspiring.
Just now I realised, of course @astroroyalscot.bsky.social was there!
