pre-writing a devastating obituary for your enemy is god-tier hating of a kind you don’t often see anymore. renaissance haterism. beautiful stuff.
A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

The secret that #BigMaths doesn't want you to know is that real numbers are vectors, complex numbers are vectors, matrices are vectors, and even tensors are vectors.
You might ask "is there anything that is not a vector?" and the answer is "spinors". But spinors are evil.

Come and listen to me blabber for a few hours about light scattering!
The first lecturer of #PLASMONICAschool2026 will be @jacopobertolotti.com from University of Exeter (UK). He is an expert of imaging through scattering media 👓 and optical computing 💻 and will teach us the fundamentals of optical wave scattering from single particles and in diffusive media 🥛.

obviously the real lesson here is that author lists are arbitrary anyway, defined by the field, and say nothing about quality of the research

Is the UK's immigration system easy to navigate?
No.
Is it inexpensive to apply to?
Also no.
Does it run efficiently and predictably?
Haha no.
But at least once you're in the country you'll not be arbitrarily kicked out of it, right?
I'm afraid we have some bad news about that.

The costs of the UK’s Global Talent Visa looks a trifle high in comparison to competitor countries - largely through the Immigration Health Surcharge (which critics say is a form of double taxation as they contribute to the NHS through normal tax on their earnings)

I've received an 'exclusive' invite to try Nature's new 'research assistant', which will burn down a forest to provide a 'summary of the paper' I'm reading and I have SUCH exciting news for them, that's called an 'abstract' and the actual authors already wrote it for me, no forest-burning required.

In its simplest form Monte-Carlo integration allows to estimate a area/volume with complicated boundaries by taking a number of samples and looking at which fraction fall inside the object of interest.

This would be the most sweeping internal reform of his pontificate — and a dramatic continuation of Pope Francis’s legacy.

If Pope Leo does indeed approves a plan that effectively dissolves Opus Dei’s structure, it would be the most significant internal action of his short pontificate to date.
