49 degrees Celsius (= 120 F) down in Victoria?
Tomorrow evening @meehancrist.bsky.social and I record episode 3 of "Nature in Crisis," a new podcast series with the @lrb.co.uk.
Episode 1 looked at Rachel Carson's "Silent Spring," and is available now (link in reply).

It's not AI or additive; just a matter telling the camera what to look for and what to dial back.
I am a 'natural light ideologue' - see this blog post.

A passage below in a (good) book I am reading.
I recommend against make the bet - your dollar may well be lost. One can photograph reds and oranges underwater without added light; just have to tell the camera to scour its input for the tiny amounts of red coming in, and ramp them up in the mix. 1/

A new podcast series through the London Review of Books (@lrb.co.uk): "Nature in Crisis." Close readings of books about nature, conservation, climate, & energy.
Once a month, with myself & Meehan Crist.
Episode 1, out now, is about Rachel Carson's "Silent Spring."

But now I don't think that the shell movement was incidental. The 'pause' before the release makes it unlikely. We saw that pause often with very clear gatherings-and-throws in our later data.
Here's an excerpt of the video, just with the 'throw.' 3/

At the time, I worried that this might have been a case where one octopus blew a water jet at another and happened to project some shells as well.
I discussed the case way back, on my blog.

(This case is not used in our 2022 paper on the topic.) 2/

Searching through old octopus files for something, I came across a video from 12 years ago. One of our first videos of possible projectile use by an octopus.
The other octo is definitely hit, but the aim was not great.
I put onto YT a better version of the video. 1/

... the tension between tenacity & innovation in science, and the relation between individual & group-level properties. Not Polanyian themes so much.
Thanks to Macario Mina for a nice review of TR2, which he calls "a guide for navigating stormy seas." 3/3

Others have also suggested Polanyi, thinking that Kuhn gets more credit than he should – and should have cited P in 'Structure.' Tsung-Yun Tzeng wrote to me in detail about this, & sent work by Struan Jacobs. I did have a look. To me, the most valuable Kuhnian ideas concern... 2/

A review of the second edition of 'Theory and Reality,' in Spanish, by Macario Ofilada Mina.
I don't read Spanish, and used a translate site.
Mina suggests that both Polanyi and Whitehead might have been included..

Each year round this time, Rainbow Lorikeets come in and make a huge fuss round some high tree hollows (where some Galahs raised a family in 'Living On Earth'). They make a stack of noise, rip things up, check it all out... and then leave again.

A favorite encounter of 2025 – bobcat, Point Reyes (California).
Bobcat not lioness, but the image brings to mind the Iranian protestors right now.

Here I used an old (abandoned) paper by Tim Scanlon (1972). This part is just me; Ben shouldn't be assumed to agree (or disagree). Freedom of expression can be justified through its link to autonomy in belief formation. This is a basis for broad 1st-order tolerance & some 2nd-order intolerance. 5/

"Toleration of the intolerant" is not paradoxical when it's 2nd-order intolerance of those who are 1st-order intolerant. A complicated framework, but it helps. In the lecture I also defended broad 1st-order tolerance in the case of speech. 5/

This was the Karl Popper Memorial Lecture at LSE.
I'm applying to speech a framework developed with Ben Kerr for understanding tolerance in general, especially in relation to "toleration of the intolerant."

Preprint: petergodfreysmith.com/wp-content/u... 4/

In the case of speech and elsewhere, we should understand tolerance using different levels: 1st-order tolerance (or intolerance) is directed at 'ordinary' behaviors; 2nd-order tolerance is tolerance of 1st-order policies, and so on. Different questions arise at each level. 3/

Free speech thread: In the aftermath of the Bondi murders, the state govt here is moving, unfortunately, in the direction of suppressing protest and proscribing specific phrases.
I gave talks in 2025 about tolerance & free speech. Wrote up the main one:

What a dishevelled beauty. Does look nudi-esque. Or maybe a sea hare. (There is a 'shaggy sea hare,' but does not look too similar.)

In relation to the blog post about lights and camera gear: this is from a recent dive trip. Mine is the diminutive rig at the end (red arrow). (Blog post: Metazoan.net)

Thank you. Glad to hear it.

A natural light photo from the post:

A blog post obsessing about Phyllodesmium poindimiei, the nudibranch in the previous post.
Obsessing also about some photographic ethics – suddenly adding light to the world of these tiny creatures. Is it aversive? How could we tell? A scrap of data is included..

Thank you, from Beth's family (including Felix).

Neruda is wonderful.
Thank you for this.

A Great Horned Owl, seen in Point Reyes during my recent California trip. Spotted (while quite a bit better hidden than he is here) by Daniel Dietrich. A young one, apparently. Flew off and then sat watching as I scrambled up the hill to get a photo.
