Not hugely into the modern custom of performative remembrance, but the ferry I’m on marking the hour of armistice with the foghorn was pretty cool.

A pilgrimage I have not made for many years – Hutton’s Unconformity at Lochranza, Arran. The site where Hutton could finally prove the earth was unimaginably ancient. A place of deep history in every way.

I am the only person staying in a closed-for-the-winter field centre, next to a graveyard, in the darkest village in Britain. And this is the book I have chosen for my evening entertainment. How delightfully gothic.

Excellent thread, from one of the main Countryside Guys.
1. In the wake on Mamdani’s win, we’ll see a lot more far right anti-urban sentiment. Here’s a thread on its roots and evolution.

The idea that the city is evil and corrupt, and the countryside innocent and pure, goes back a long way: to Theocritus in Alexandria, and to the Old Testament. 🧵

A blessed Samhain all. I have prepared sweets for around 50 kids. I am expecting maybe four.

I hate this factoid. If they "appear blue to the human eye", they're blue. That's what blue IS. How the hell else can you define a colour?

It's awesome that people are rediscovering the lost Samhain art of turnip carving, but I'm begging you all to realise that the one you keep seeing pictures of is a plaster model made by an artist. You can go see it in the National Museum of Ireland! www.museum.ie/en-IE/Collec...

In Ireland, at Halloween, we carved turnips to create scary-faced lanterns. The term, Jack o’ Lanterns, takes its name from the folktale about Jack, who was welcome neither in Heaven or Hell and was d...

Someone should make an edition of Moby Dick with a bunch of added chapters where Ishmael talks about all the whale facts we've learned since that book came out.

Being performatively helpful or polite is annoying and unhelpful. If three people are already tidying the kitchen after dinner, sit your ass down. If you have right of way, just sail on by.
Do you have any extremely niche, but serious, ethical stances?

It’s clear that the international community are going to count ‘background levels of murdering civilians’ as Israel adhering to the ceasefire.
BREAKING: A Palestinian was killed by Israeli fire east of Gaza’s Khan Younis amid the first phase of the ceasefire, according to sources at Nasser Medical Complex.

This is why increased electricity demand is the big problem here. All that technological progress doesn't matter one iota if we keep burning increasing amounts of coal.
The chart shows where we humans get our electricity from. Coal is still a significant part of the mix. Phasing coal out will take decades. A young environmentalist is probably well advised to become an engineer and push for cleaner alternatives by making them cheaper. Source: buff.ly/gjZpGsq

Was once told my late-submission request for a paper on dinosaur anatomy had been missed, and I could either write to the exam board pleading my case, or hand in by 4pm that day and eat the 5% late penalty. I spent that five hours knowing more about dinosaur anatomy than anyone on earth.
I wrote a 15 page report on heraldic symbolism in medieval armor and weapon design for my art history class the night before it was due (8am class). Made up 90% of it (only found one book for reference) and got an A. GenAI could fucking never.

This is great, BUT the year we burned the most coal was 2024 and it's still going up.

a computer-generated lifelike animation is not an "actor" and having to say that makes me feel like i'm the insane one

As someone who knows nothing about palaeontology, I'm utterly convinced we've got helicoprion totally wrong. No way that's a coiled tooth-magazine. Like when we thought anomalocaris jaws were headless prawns.

Got @volcanologist.bsky.social’s new book in the post. Can’t wait to read the whole thing, but will be starting with chapter 4 as a matter of urgency.

Spectacular concentric zoning and twinning of large titanaugite in essexite (nepheline monzogabbro) from Lennoxtown, Scotland. Plagioclase inclusions within the phenocryst align with zoning just as proximal groundmass plagioclase align with its edge. #ThinSectionThursday 🧪⚒️

One of my favourite bits of Moby Dick is this chapter where Melville basically says "a bunch of weird dorks keep telling everyone whales aren't actually fish but look at them... swimming around in the sea... of course they're fish".
To be short, then, a whale is a spouting fish with a horizontal tail. There you have him.

New series: guess the slightly silly mindat entry. @mindat.bsky.social

Ian Holm's delivery of this line was very fun and silly, and really showed you're dealing with an ACTOR actor.
‘I don't know half of you half as well as I should like, and I like less than half of you half as well as you deserve.’

Happy Hobbit Day!

Thought I already knew most of the very silly minerals, then along comes paddlewheelite. Ridiculous.
Atomic steamboats and crystal spider? It's not an art show, but it is a great display piece! You can vote for which one gets top billing at mineralcup.org today!
