A splendid cold walk to Fiddlers Gill to see the fab but rusting Victorian #Braidwood Telescope! Once part of the now long-gone Lanark Observatory, its optics are safe at the Lanark Museum. Sadly I see no hope in restoring this beauty tho, that's been long-abandoned in this field ☹️ #histsci 🔭🏴󠁧󠁢󠁳󠁣󠁴󠁿

Happy belated birthday to JWST, which was launched on Christmas Day 2021. I hope it has many more years of transformative science ahead of it. 🧪

Face pareidolia is what AI suffers from.

In 1977, American physicist John H. Van Vleck won the Nobel prize for his work on magnetism. In his Nobel lecture, amid a discussion of rare earth elements, one sentence leaps out: "Miss Frank and I made the relevant calculations." Who was Amelia Frank? theconversation.com/who-was-amel...

who's oil? www.theguardian.com/us-news/2025...

Does anyone know on what legal grounds the US is blockading Venezuela? Maybe they can find a way to blockade tankers carrying Russian oil too.

This is such an astonishingly bad take I don’t even know where to start?? During my PhD and my time as a science journalist I have spoken to a LOT of scientists. Almost every single one has more ideas than they have the time or funding to pursue. Please do better @vox.com 🧪

TIL about a memorial ceremony in Iceland in 2019 to mark the end of a glacier, changing the place name from Okjökull to Ok (jökull = glacier). Uncompromising wording on the bronze plaque: "This is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it".

One step in the right direction from @cnrs.fr . Here’s hoping others will follow and we can get some more space for actual science. 🧪 www.cnrs.fr/en/update/cn...

1988 interview with physicist Victor Weisskopf. We overlapped at MIT when he was emeritus and I was a postdoc, but I never really chatted with him (because I'm an idiot). In 1934 he and Wolfgang Pauli wrote the first paper insisting that everything is quantum fields! www.youtube.com/watch?v=utZY...

Clip from the Tokmakia plateau (NE Lesvos): a mesophotic coralligenous reef with dense red gorgonians and complex bioconstructions. This is the kind of “animal forest” habitat our work focuses on documenting and conserving. #coralligenous #gorgonians #oceans @skatsanevakis.bsky.social

Same area, but now with the pressure visible: longlines, ropes and other fishing gear litter entangling gorgonians and covering the seabed. Chronic ghost fishing and structural damage that we urgently need to address. #marinelitter #ghostfishing #MPA #conservation @thanasisnikolaou.bsky.social

Amazing the way things develop sometimes. My idle displacement activity to put off assessing a pile of 🔭 applications for ESO (arxiv.org/abs/0906.1943) has led to a wholesale national shift in the way that 🧪 grant applications are assessed (www.gov.uk/government/n...)
