to borrow an acronym from computer science: RTFM!!! (Read the F****cking Manuscript)

Catching up on the arXiv discourse:

@Kaju_Nut What is the reasoning for Planck length being the limit till where our physics works? I have seen this argument many times but didn't find any proper reasoning.

We don't expect our picture of space/time to hold below Planck length. Maybe space and time are emergent. Maybe there is a discrete structure even, like in causal sets. But whatever it is, it has to get around special relativity. That has not been so easy! n/n

But we haven't seen any violations. The lesson here is that measurements being discrete does not imply space/time is not continuous. Relativity shows that's a bad argument. So are they continuous? We don't know because we don't know quantum gravity

Hmmmmm

@entanglednomad Thanks❤️

@eviciium woww congratulations 🎉

Submitted my master's thesis🥳. Need a big break now😭

Yvonne Choquet-Bruhat (1923-2025) Lydia Bieri, Jean-Pierre Bourguignon, David Garfinkle, James Isenberg arxiv.org/abs/2605.01956

Hell yeah😤

@fynmaaandu Special special relativity?

What the heck is this doubly special relativity? Does anyone have any idea?

@bcubeddd He was an engineer with epic skills and epic gear🙃 youtu.be/rp8hvyjZWHs?si…

go see a doctor. A medical doctor!

@xiNietzsche I feel in a similar way. I don't have any affection towards math. My only goal was to understand physics in detail and depth (which basically lead me to learn lot of new math). Now I see all the people I want to work with are in math dept and it scares the shit out of me😭

俺は数学ばっかやって物理に戻ってこれないとか思われるかもだけど、実際のところ、腰据えて数学やるのは怖すぎて無理だし、やっぱり物理の中で数学がいることを発見するのが好きみたいなところはあるし、hep-thの話題はマジでカッコいいので結局物理。今はかなり数学やってるようだけど。

I watched the movie Perfect Days(2023) recently and idk how to explain but the tracks of this movie make me feel really calm. On top of that I listened to the tracks while playing Alto's Odyssey and it has been my favourite digital experience so far😌.

What if arxiv mails were delivered like this😆

@nomoneyforfilm Congrats🥳

I got a PhD offer!!

How long do you think prime Planck could hold a plank? My guess is 1 min.

@subarusatosi @star_stufff Thanks❤️

@eviciium @star_stufff The author is Ryoyu Utiyama(内山龍雄). He is famous for "Invariant Theoretical Interpretation of Interaction", Phys. Rev. 101, 1597 (1956). journals.aps.org/pr/abstract/10… The text book is shokabo.co.jp/mybooks/ISBN97…

重力場のラグランジアン密度の一意性と、重力場の方程式の一意性についての重要な定理(内山『一般相対性理論』pp.91-92)。 この定理や証明が載っている本は意外に少ない(定理9の証明は『一般相対性および重力の理論』にある)。

Is it weird that my mood for the day depends on ArXiv submissions?😭

@vrundasays_ That band member from Queen who did PhD in astrophysics. Idk his name tho

I need more examples of people in academia who haven't had a linear path at all and missed years on the way to PhD and still did their PhD. I don't wanna feel all isolated here 🫩

@four_form Thanks ❤️

@eviciium Totally reasonable question! Some answers: 1. Flex 2. It's a way to measure gas pressures at levels that are currently so low that existing sensors just measure 0 (arxiv.org/abs/2303.09922) 3. Characterizing backgrounds for fundamental physics measurements we want to do

2024: proposal to make a gas pressure measurement by literally counting every collision with a sensor 2026: measurement. Could not be happier to see this work exactly like we drew it up arxiv.org/abs/2604.18371
