- Reposted by Jacopo BertolottiMany people have wondered why the Chien-Shiung Wu never won the Nobel Prize for Physics. New findings from the Nobel archives, exclusively revealed in Physics World, show she was nominated 23 times by 18 different physicists - and yet was still left empty-handed. 🧪⚛️ physicsworld.com/a/twenty-thr...

- Reposted by Jacopo BertolottiIt's weird I was REPEATEDLY told that payment processors "had" to ban all nsfw to mitigate the risk of processing CSAM. So if that's true then why wasn't X immediately dumped by every one of those payment processors when Grok turned into an automated CSAM generator?

- Reposted by Jacopo BertolottiThis seems like a maliciously put headline to make people feel a certain way. Wikipedia is not partaking in generative AI. They are making AI companies and scrappers having to pay for training their modules off wikipedia texts. And having an AI (not that ai) tasked with updating dead links.

- Reposted by Jacopo BertolottiWe've got ISSUES. Literally. We scraped >100k special issues & over 1 million articles to bring you a PISS-poor paper. We quantify just how many excess papers are published by guest editors abusing special issues to boost their CVs. How bad is it & what can we do? arxiv.org/abs/2601.07563 A 🧵 1/n

- Students sometimes fail to appreciate that relativity did not emerge fully formed from Einstein's head. I for sure failed to appreciate how long before Einstein's 1915 general relativity paper people were already discussing the idea that mass might distort space-time. ⚛️🧪🎢

- Quantum mechanics is a wave theory, and once you look at it as a wave theory 99% of its weirdness completely disappears. (The "wavefunction collapse" is the only part that is not about waves, and also the only part that is genuinely weird.)
- Paper accepted! 🥳 "Explaining and exploiting the radial memory effect in multimode optical fibres" (A slightly older version is on ArXiv: arxiv.org/abs/2508.11389 ) 1/3 💡 ⚛️ 🧪 #OpticalFibers
- When (coherent) light propagates in a multimode fibre, each mode accumulates a slightly different phase, so the output looks like a random speckle patter. But it is NOT random! This non-randomness has a number of consequences. 2/3
- We show that a focused input will always result in a ring of excess intensity at the same radius of the input, we give a simple but rigorous explanation of why this happens, and suggest how this might be useful in practice. 3/3
