No, I think that was Architeuthis: even bigger, and orange.

We’re working on it! But we can’t trust America going forward, it has proved too fragile. With luck we will again find ourselves fighting on the same side, but we will never dare to rely on you again.

Slightly unfair to Gollum, who was not wholly evil at heart and became corrupted by forces that he could never have withstood.

Isn’t that the weirdest thing? Here we sit, unbelievers, and go “tick, tick, tick, yep, he’s the Antichrist so these must be the End Times.” This was not on my personal lifetime bingo card.

You couldn’t do the illuminations in June though, could you? They would only just about be visible between 11pm and 1am. So there’s that.

Rysk propaganda-bingo. Det enda som saknades var “krigshetsare”.

I can see that policy coming off the rails but generating substantial impact.

No, it was Puer Natus. I’ve not heard it before.

It is usually safe to assume that the top 🇪🇺 diplomat is not being naive. Every word will have been weighed carefully and uttered with purpose. Conversations behind closed doors are likely quite different.

Not that one, but we did get Mr Bucton his Galliard which one of my Dowland favourites. Also pieces by Van Eyck, Parsons, Holborne and Byrd. The soloist was Erik Bosgraaf.

To clarify: the specific Peace Prize troll could not have been planned, but the general focus on international cooperation for peace certainly was.

I do not imagine for a second that it was unintentional.

The animations are incredible. Here, a Hiroshima theme with a flock of origami cranes.

City Hall (Stadshuset), where the Nobel Prizes are presented, is lit up with Nobel-themed illuminations. This year the theme is the Peace Prize.

Stockholm City Hall, a monumental building with a tall tower on the left, lit up with projected images. At the top of the tower there’s an image of a Nobel Prize medal.

In Stockholm for a wonderful concert of English renaissance music performed by a recorder consort. Then on to the atmospheric Christmas market in the Old Town:

A market scene at night: crowds, lit-up stalls, ancient houses in the background.

Mar-a-Lago face is deeply bizarre. In “before” photos they all look human and sometimes quite pretty in an ordinary sort of way; “after” is monstrous, inhuman, mask-like, expressionless and coldly evil. It beggars belief that someone would consider that an improvement.

Per Ahlberg @perahlberg.bsky.social · 1d

Sorry, that's a major misunderstanding. The nations of the "Warsaw Pact", and the nations such as Latvia, Lithuania and Estonia that were directly incorporated into the USSR, were free countries between WWI and II but were captured + enslaved by the USSR at the end of WWII.

I don’t know that the likes of Ken Ham really do “learning” the way we understand it.

In essence, yes.

forth over time) you can get marine and terrestrial sediments In alternating layers, allowing you to tie together their fossil sequences. Some microfossils, notably land-plant pollen, also occur in both marine and terrestrial sediments.

Per Ahlberg @perahlberg.bsky.social · 2d

each layer of sediment contained its own characteristic fossils, which changed in an orderly manner. There could be gaps in the sequence, but it was never out of order. Of course marine and terrestrial fossil sequences will be different, but in some places (where a coastline has fluctuated back and

Sediments of the exact same age at Maastricht in the Netherlands are quite different, marine limestone containing the bones of mosasaurs. (The first one ever found was discovered there in the 18th century. Mosasaurus means “reptile from Maastricht”.) The key discovery, in the 19th century, was that

Per Ahlberg @perahlberg.bsky.social · 2d

The actual character of the sediment will vary from place to place, of course, just as it does today. For example, the latest Cretaceous rocks in North Dakota, about 66 million years old, belong to what’s called the Hell Creek Formation; river sediments containing fossils of T. rex and Triceratops.

Next you’ll see citizenship as a concept revoked and replaced with subjectship.

Per Ahlberg @perahlberg.bsky.social · 2d

Yes, there is. And it was worked out long ago, much of it in the 1820s due to the work of pioneers like William Smith.

You need a lot of coal to power a Newcomen steam engine. Which seems to be where you’re headed.

That's an anglerfish (or goosefish), Lophius piscatorius, not a wobbegong.

Very like ones at St. Brendan’s Well on Valentia Island. I have been there several times while doing fieldwork on the Devonian tetrapod tracks that occur in the coastal cliffs of the island.

No, not forgotten but remembered. That’s the whole point. Forgetting is dangerous. Witness the resurgence of fascism as the WWII generation dies out.
