New postdoc position advertised in geometric analysis (and/or math-GR) with me in the frozen wastelands of the north (Luleå, Sweden) web103.reachmee.com/ext/I003/583...

Okay, now I’ve found their “Bagpipe Practice Room” I think Scotrail might just be having us on!

Anyone in the math GR / geometric analysis communiy know anyone who's in need of a postdoc around 1 year from now and would be interested in coming to the frozen wastelands of the north? (And has/will have a non-Euro PhD)

I asked ChatGPT if it knew who I am based off of our chats. The answer was (obviously) yes 😅

If kids’ schools trained them for work based on what everyone thought the hot new technology was going to be, both my kids would have spent the past several years learning about the blockchain. This is why schools don’t attempt to do workplace training: life is pretty long.

A last little bit of swedish summer yesterday Guitar and some beers, spotted some berries, and then made a little spiky friend

New paper day! 🥳 arxiv.org/abs/2506.11841

I'm told that when I was really little, I was running into the motion sensor to open the door of a store before arriving customers triggered it When I was visibly upset for being too slow, a group stepped back and let the door close again so I could "open it" for them -- it was the band Wet Wet Wet

Seems arXiv now uses AI to try to convince you that you're misclassifying your own paper's subject area 🙃

The amusing thing is that there *is* an etymological connection here... And of course some variation of calling townspeople "burgers" exists in almost all European languages. It's where "bourgeois" comes from even. And connected to place names like Hamburg, Edinburgh, Strasbourg, etc. (I think)

Can any physicist explain this idea of boundedness of the Euclidean Einstein-Hilbert action in the context of this paper? (Purely from a GR/geometric perspective, no path integrals) arxiv.org/abs/2505.13600

Not only is this true, there are 33 whole-ass mentions of this in the script and each one is freaking hilarious whills.nu/4/sw4.html#h...

Just got some art done by Alexandr Elichev for my latest homebrew Frosthaven class and wanted to share it somewhere :)

How normal is it to write words correctly, but write the letters in the wrong order? Sometimes when I write fast, I fill in the letters the wrong way. Eg. When writing "Letter" in the middle of a sentence I might write the "ett" then the "L" in front of them and then the "er" ... it feels weird

Well this can fuck right off www.theregister.com/2025/04/27/d...

I said my main goal of this trip was to meet with Kilmar. Tonight I had that chance. I have called his wife, Jennifer, to pass along his message of love. I look forward to providing a full update upon my return.

On the anniversary of the sinking of the Titanic, we thought we'd answer a question that's often asked, "If they raised the Mary Rose, why not raise the Titanic?" Allow our scaled diagram to explain...

Someone should make a collage of all the posts where people predicted this the moment he pivoted to weird religious zealot

Huh, weird

I apologise for nothing

The other day in a lecture I was using an outstretched arm like a traffic cop to indicate vectors in different directions and then after something like i+2j+k I ended up saying "whoops, nearly did an Elon Musk impersonation" moment 🙃

I received a heartbreaking email today: A paper in a special issue I’m editing is being retracted because one of its authors is afraid of losing their job and their legal status in the U.S. if they publish a scientific study on evolution. Yes, on evolution, nature's engine of diversity.

Brutal.

How do you response to AI generated emails? Especially those where it's clear that the LLM that wrote it wasn't given full information... Like, how is this a thing

oh man now another of his videos is recommended to me, and he's unsufferable... www.facebook.com/reel/1189366...

And there it is! First article of 2025 is published :) link.springer.com/article/10.1...

Victory! They folded and have properly credited people in the latest proof :D

Happy to announce our upcoming conference on Causal Fermion Systems in Regensburg in October. This is the first time that we gather the growing international community. Come join us! causal-fermion-system.com/wp-content/u... Also please share far and wide.

Academic at Duke Uni filming himself and his students while he hangs shit on his colleague for using whiteboards and teaching a technical course, and recommends nobody take that course... Teachers, never do this. www.facebook.com/reel/5846219...

Cosmologists, I have questions about comoving observers that I can't quite figure out how to formulate... But I'm gonna try here in the hopes someone can help me understand a little better... I'm thinking about the Milne model because it's something geometric and familiar. (1/N)

Has anyone ever had an accepted article "un-accepted" after disagreeing with "style" changes introduced in the proof stage? I'm once again in a back-and-forth where I won't allow a journal to reference work of 2-3 alphabetically listed authors as "Aaronson et al."

Got the ad out! Share with anyone who might be interested :) Two year postdoc in geometric analysis and/or mathematical general relativity: web103.reachmee.com/ext/I003/583...

It's about time the world stops being so reliant on US technologies...

Paper accepted 🥳

Found an American recipe for mac and cheese, but used västerbotten cheese that a local craft brewery put through their meat smoker for me. This was my best ever idea.

There definitely are some things that this new AI stuff is valuable for...

I spoke to a talented junior scientist who just got a good faculty job offer in the US and they told me “well I wouldn’t move to 1930s Germany either” so that’s how that’s going

Course evaluation report day 🥳 I was a little anxious about this one, because I've completely overhauled a course and was running on fumes getting things together. So it really made my morning to read all the very positive comments 😊

Trump is gonna do something like threaten to leave NATO if Denmark doesn't give the USA Greenland and I bet you his ploy will fucking work. -_-

"Next week I'll be less busy" I lie to myself, as I spend all of Saturday morning grading

The entire nation of Australia gets it. Media in that country are having to blur what Elon Musk did twice in public today because of laws there regarding the Nazi salute.

He was karate-chopping the neck of a transgender ghost. Calm down everyone.

Sharing this for anyone who might be interested. Some great speakers on the geometric/mathematical side of general relativity, aimed at students and young researchers. math.ku.dk/conferences/mathematical-relativity
