Just your regular reminder of where global CO2 emissions are tracking compared to scenarios that keep warming to below 1.5C in 2100, with "no or low overshoot" (maximum temperature around 1.6C). journals.sagepub.com/doi/full/10.... C1/

Amazing! Noether's theorems used to be a complete mystery to me: getting conservation laws from some quite basic symmetries? How?? Well, here's how:

Tohle je hodně podstatný pro urbanismus ve 21. století, které bude plné politických otřesů, nedostatků zdrojů, přírodních katastrof a útoků na sociální kohezi: Čas vyfintěných náměstíček z mramoru skončil. I velké změny mohou být rychlé a nízkonákladové, utvářené zdola, pružně reagující na situaci.

Obviously things have got dramatically worse in the US recently, and I don't want to diminish that, but I've been at *so many* conferences in the UK on topics like empire, humanitarianism and development where multiple speakers from the Global South have been denied visas or held at the border

When I say you don’t have to worry about microplastics in your brain I mean that there is much stronger evidence that you should be worrying about other things that you don’t ever think about, like the draining of peatlands for agriculture, and things that you think about all the time, like fascism.

1. LLM-generated code tries to run code from online software packages. Which is normal but 2. The packages don’t exist. Which would normally cause an error but 3. Nefarious people have made malware under the package names that LLMs make up most often. So 4. Now the LLM code points to malware.

Docela fascinující rezignace na (pokusy o) popisování reality výměnou za "názory osobností". Na tohle fakt veřejnoprávní média nepotřebujeme.

The design and build quality of this hospital in Barcelona is remarkable Even more so that it achieves this despite needing 2m thick concrete walls (to limit radiation) and 1m2 of mechanical floor area for every 2m2 of clinic

I have better lighting, so here are photos of the final cupcakes. I don’t do this professionally or often but for family birthdays I will bring out the decorator tips. It’s a fun art form to play with. These are vanilla cupcakes with raspberry curd filling and buttercream flowers for my sister.

This is insanely good...and terrifying. From now on "Sparta" sounds like "Hitler" to me.

I take back any mean thing I've ever said about cats. When you've gone through “the murder pathway of domestication,” you get to be a bit of a jerk. That story and more of the best in @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... 🧪 🐈

ThermoFisher tell us their CellTracker dyes are not transferred to neighbouring cells but we see significant transfer @24h when we mix stained with unstained cells. Any suggestions how to label cells reliably so that we can track distinct populations with no or minimal transfer? 🧪 #fluorescence

Sekyra Group se rozhodla ve své pražské čtvrti Rohan City pojmenovat ulice po filozofech. S argumentem, že chce do veřejného prostoru vnést ducha svobody a morálky. Vnesla však jen potvrzení, že komodifikovat lze i filozofii. @denikreferendum.cz denikreferendum.cz/clanek/23732...
