Yes. Exactly — the infinite loops weren’t fun.

People write their horror stories about accidentally clicking “reply all.” But I once set up an ‘out of office’ message that somehow went out in response *to every email I’d ever received*.

Sunday night reading: why the Second Law of Thermodynamics is not quite what you probably learned. With quantum systems there's an extra bit that can mess with and even reverse heat flow. And we can use that to detect "quantumness".

“Anomalous” heat flow, which at first appears to violate the second law of thermodynamics, gives physicists a way to detect quantum entanglement without destroying it.

#OnThisDay 100 years ago, plans for a new University Library in Cambridge were gaining traction.

By 2 October 1925, a site had been acquired and architect Sir Giles Gilbert Scott RA had begun his sketches and costings.

As this picture shows, by 1933, construction was underway!
(Cam.a.934.2)
Photograph showing the construction of Cambridge University Library in 1933. We see the partially completed front elevation of the building. Some of the metal girders of the building are still visible.

I like the idea of coffee at the hairdressers, but invariably it ends up hair-infused. #thoughtfortheday

Here's a reminder on #InternationalCoffeeDay: It's OK to take a (coffee) break. ☕

"It’s ... helpful to have a venue to share the day-to-day ups and downs of life as a grad student," a #PhD student wrote in this 2019 #ScienceWorkingLife. https://scim.ag/4nvLTBb
People arm in arm while drinking coffee and holding papers, with text: Why scientists should take more coffee breaks.

Happy 120th birthday, special relativity!

Albert Einstein introduced special relativity in the paper "On The Electrodynamics Of Moving Bodies," published in Annalen der Physik #OTD in 1905. 🧪 ⚛️ 🔭

Manuscript: onlinelibrary.wiley.com/doi/abs/10.1...
English: www.fourmilab.ch/etexts/einst...
A black and white photo of Albert Einstein, around age 25, sitting at a desk. He is a wearing a flannel suit and resting his right arm on the desk. Einstein is looking to the left of the photographer in this posed photo. The first paragraph of the paper, in German. Translated to English is reads:

It is known that Maxwell's electrodynamics—as usually understood at the present time—when applied to moving bodies, leads to asymmetries which do not appear to be inherent in the phenomena. Take, for example, the reciprocal electrodynamic action of a magnet and a conductor. The observable phenomenon here depends only on the relative motion of the conductor and the magnet, whereas the customary view draws a sharp distinction between the two cases in which either the one or the other of these bodies is in motion. For if the magnet is in motion and the conductor at rest, there arises in the neighbourhood of the magnet an electric field with a certain definite energy, producing a current at the places where parts of the conductor are situated. But if the magnet is stationary and the conductor in motion, no electric field arises in the neighbourhood of the magnet...

Turns out the ‘magic’ coffee in the coffee shop just has an extra shot of espresso. And now my hand is trembling somewhat. 😵‍💫

This makes it look like I’m objecting to your joke.

Amazing run by Cambridge alumnus Amy Hunt for a silver medal in the 200m at the World Athletics Championships.

Google's "AI mode" is basically a means for paraphrasing without assigning credit to the source. In niche areas (e.g. philosophy of science) the sources used are so narrow that it as good as guarantees that people who use it in the writing process will end up plagiarising the work of others.

The Marathon at the World Athletics Championships had both a false start and a photo finish.

It was a smart move for Radiohead to wait for all the Oasis fans to spend their annual gig money before announcing their shows.
