Out in the forest again for more bilberries, and this time we chanced upon a stand of peach-leaved bellflower (stor blåklocka in Swedish), Campanula persicifolia. It was the favourite flower of my grandfather, Rudolf Forssell (born 1889), and always flowers around his birthday.

A stand of tall blue bellflowers, each stalk carrying 3-5 flowers, against a background of greenery and fallen tree trunks.

Having seen Nolan's Odyssey today, in its IMAX glory, I'm minded to share my thoughts about it. My qualifications for joining the furious hubbub are an interested-amateur knowledge of Greek mythology and Bronze Age archaeology, and...err...that's it. But lack of expertise hasn't stopped anyone else,

"Hence our dismal conclusion: rather than finding that LLMs free us to do a better job of what we were doing before they came along, they shift scientific incentives (and the playing field of academic competition) in ways that compel us to do more and more, faster and faster, less and less well."

1. We—@eduede.bsky.social, @mjcrockett.bsky.social, Kevin Gross, and I—have a new preprint on the arXiv today, based on ideas that emerged during an @sfiscience.bsky.social workshop in November 2024: The unintended consequences of large language models as a labor-augmenting technology in science.

The strangest thing happened today. We went to the uninhabited island of Lunga, west of Mull, to look at the puffins nesting there. I was just taking photos when I felt a thump as something landed quite heavily in my head. It was a puffin! It stayed for about a minute before flying off.

A man with his back to the camera, wearing a blue jacket and a grey woolen hat. A puffin is sitting on top of his head. On the left, an arm holding a mobile phone can be seen. In the background, a green slope and the sea beyond.In this photo the puffin is taking off.

Some roses, because it’s rose season. Rosa gallica var. Officinalis, the Apothecary’s Rose, also the Red Rose of Lancaster. Perhaps the oldest rose in cultivation. The camera struggles to capture its extraordinarily intense colour.

Two intensely coloured reddish-pink rose flowers against a background of green foliage.

High summer is here, hot and humid, as we get a lick (but thankfully no more than that) of the infernal heat wave that’s tormenting continental Europe. The pond looks like a documentary from the Pantanal. And the first water lily has opened! The lovely James Brydon. Golden lily in background.

A pond covered in water lily pads, with a single pink flower in the middle. In the background a pair of white garden chairs and a clump of lilies with small golden-orange flowers.

Only it doesn't. It doesn't upend anything, because NOBODY in the early tetrapods research community believed that all early tetrapods had a tadpole-like larval stage or that this was a key enabler of the transition to land. I have been at the heart of this community for 40 years and I KNOW.😡

Husaby Church, near Kinekulle. The place where king Olof Skötkonung converted to Christianity and was baptized in 1008. The tower is late 11th century, possibly the oldest stone building in Sweden (excluding Skåne, which was Danish then). And yes, it really looks like this! No filter.

A fairytale tower with three pinnacles, seemingly rising out of a sea of daisies and framed by verdant foliage.

On the road back home, stopped off in the town Lidköping for lunch in its lovely 17th century Old Town Hall. But what’s this? A plaque on the wall points to a nightmarish revenant from 20th century British horror fiction.

A multistory, almost pagoda-like, red wooden building with black shingle roofs. In front, an expanse of lawn edged by flower beds.

As a slight tweak on the theme, here are three perfect covers, all from the golden years of the late 60s: 1. Joe Cocker - “With a little help from my friends” 2. Janis Joplin - “Summertime” 3. Jimi Hendrix - “All along the watchtower”

Today we made an excursion to Store Mosse National Park, just a stone’s throw from Hädinge. The largest area of bog in southern Sweden. Absolutely vast, what you see in the photos is just a small part.

A dark grey signboard with the words “Store Mosse nationalpark” in white. Forest in the background.

Here’s where we spent Midsummer: Hädinge (near Värnamo in Småland) in the evening sunshine. Big family gathering, a whirlwind of children and dogs. A good time was had by all.

A cluster of wooden houses, some painted red with white window surrounds, nestled among trees beneath a cloudless evening sky. In the foreground, a green field of growing grain.

Timeline cleanser. Stjärnorp Ravine - somewhat surprisingly, owned by a branch of the Douglas family since the 17th century - offers flowing water, birdsong, and swathes of ostrich-feather fern.

The first roses are out! First out the gate, as usual, is this white Centifolia. Uncertain origin, probably Dutch 16th century. Delicate flowers, but the plant is a 2 metre tall cascade of living barbed wire that tried to snag me every time I pass.

A white rose with a pale pink centre, very double, surrounded by foliage.
