A corridor chat with Chris Smeenk, professor at @westernu.ca, about correcting common misunderstandings about the Big Bang and the early universe. Chris' research centres around the scientific method and the nature of our knowledge of physics.

And it happens again - original email 9:12 PM on Friday, harassing follow-up 9:12PM on Sunday. You won't believe how fast I declined that one. Journal editors: if you do this, you contribute to a culture of overwork and poor mental health, and I will NOT sacrifice that for you.

If you're an editor for a journal I've never heard of and you ask me to review a paper, don't send a pushy "reminder" less than 48 hours later. Doubly so if a good fraction of that time is outside of normal working hours (weekend). If you do, I'll almost certainly refuse to review for you.

I'm all in favour of not allowing LLM generated content. Given the central role that arXiv plays in modern physics communication they had better be sure that they are right, and have genunine transparency in their moderation process. A false positive could be devastating to a PhD student's career.

wow — the preprint host, arxiv, is banning authors for a year if they submit papers with hallucinated citations 🤖

Getting ready to teach: Lecture written PDF on flashdrive Double-checked it's available online to the students Got my notes Grabbed my laptop Jacket on, leave house, get in car Realize I'm still wearing slippers. It might be a rough one today.

Do you like general relativity but find the Einstein-Hilbert action just too conservative for your taste? Now on the arXiv: arxiv.org/abs/2605.05817 More excellent work by my PhD student, in which we show that the conformal factor can be removed in favour of friction.

Classical General Relativity as a Non-Conservative Action-Dependent Field Theory

Scaling symmetries have previously been examined for classical field theories described by singular Lagrangians; in this article, we apply these results to the first-order formulation of General Relat...

My institution insists on using Microsoft products. Within Microsoft Teams, there is a tab labelled "Teams". Within that tab, I have two sets of "Teams", one labelled "Classes" and the other "Teams". So to locate a particular discussion, I have to open Teams, go to Teams and expand Teams.

I spent a small fortune on travel to and taking the GRE, application fees, etc. I begged academics for reference letters and had no idea what the hell to write in a "Personal statement". Result: rejection letters from almost everywhere I applied. I got two offers and no clues on how to choose.

I got rejected by all program except my last choice and was waitlisted for my 1st choice. I put the acceptance letter to the former in an envelope, went on a 5 hour bus overnight busride planning to post it at the destination. Woke up to a phone msg from latter frantically asking me to call back.

Also your goal to "develop and validate scalable indicators that can identify novelty in research" looks like you want just another way to boil complex research down to a number which will be gamed like every other index (Citation count, h-index etc) and contribute yet more bullshit to research.

Not a great sign that your metascience project will be able to access expert assessment when you match me to a research area nowhere near my own, based on a paper I didn't write.

Email text reading: "To David Sloan,

The UK government's Metascience Unit and the University of Sussex are keen to receive your expert assessments on the novelty of selected publications within your expertise.

We have matched your work (Exploring pedagogical culture for accessibility education in computing science. (DOI: 10.1145/2899475.2899490)) as relevant to at least one publication in our project, which we would like you to assess."
