Physician who was no longer at the hospital but was on the email list had Otter ai installed and his bot “attended” the meeting, generated a transcript, and sent it to all 65 people on the email list, 12 of whom also no longer worked at the hospital.

🧵 With over 20 runs of the course & 21,000 learners, the Sustainable Futures course we made a few years ago is a runaway success.
Why does it matter?
It looks at local and international case studies covering the environmental, social, economic and cultural pillars of sustainable development.

I appreciate that this is technically a comprehensible sentence (and pretty benign in terms of how complex the concepts are), but the density of jargon did hit me with that vague feeling of "am I having a stroke".

Roughly speaking, the prompt to the discussion was "big things are happening elsewhere, how are we going to respond to this in our field?", and this speaker gave a very calm answer to the tune of "it is okay to still focus on existing challenges, it is not essential to respond to this other stuff".

The amount of work that goes into applying to these grants is insane -- the academics writing it, the academic colleagues commenting, the Professional Service teams finetuning and sorting out all the costings etc.
Surely that time could be used more efficiently *for actual research*?

After submitting a FOIA request UKRI, I obtained success rates by three grant call scheme and I can only say that I am disheartened by the results:
- AHRC Responsive Mode 2025: 2%

An interesting knock-on effect of various recent hype cycles at the intersection of LLMs and Maths is that I've found some motivation to care a bit more about what people really mean by "open problem".

Ever since I made a video about Fourier Transforms, one of the most requested topics on the channel has been its close cousin, the Laplace Transform.
I've been having a lot of fun animating a mini-series about this topic, and the main part is now out.

I'm looking for advice on LLM proof assessments on content related to neural networks. If I had more time with the students (I teach an intro to the topic across 3 hours, but they are masters level students), I would have them read a paper and replicate it in PyTorch.

Much of Euclid’s Elements is easily misunderstood. Some proofs seem to have logical gaps. Some constructions seem pointless, others seem needlessly convoluted.
Each of these provides a window into how the ancient Greeks thought about math and the philosophical role that geometry played.

Perhaps a bit orthogonally to the main point here, I have certainly had the experience of reading something out of { duty / necessity / etc. }, and found it remarkable how this context can amplify all sorts of frustrations about the style, even those which could otherwise be quite minor.
I skimmed a paper of an author I dislike and it's amazing how a certain style of writing --overly complicated explanations of trivial claims, new jargon that hides how vacuous it all is, an overemphasize on mathematization regardless of whether it actually maps onto the claims made-- just wrecks me.
