Inside bird eyes is a strange and mysterious structure called the pecten oculi. It looks like a pancake flipper, or maybe a radiator. Some 350 years after anatomists first described it, biologists finally figured out its purpose. www.quantamagazine.org/how-the-bird...

The last panel of the tattoo work is finally done, and healed. Hannah is amazing. #tattoo #ursamajor #whirlpoolgalaxy #leo #gemini #auriga #taurus #orion #orion #sanfranciscoskyline #tattoosbyhannah

Hannah started the last main section of the #tattoo sleeve. That's the #whirlpoolgalaxy, #ursamajor done as a mammoth, #leo, #orion, #taurus, and the #pleiades. It is only five days in, so it's still healing and peeling. Much of the coloring and shading is also yet to be finished.

This a #poem I wrote between the years 2011 and 2025. It was not a continuous effort. There were entire years in that interval during which I wrote nothing at all. open.substack.com/pub/klintusf... #poetry #art #science #philosophy

A topic close to my heart. In fascinated with the fact the dog domestication predates the development of agriculture.

The color is clearer with the skin healed. #tattoo #saturn

What if the inside of black holes are a roiling sea of space and time stretching and compressing in multiple directions? www.quantamagazine.org/new-maps-of-...

www.quantamagazine.org/climate-phys... A good read both for how it covers the current state of uncertainty in climate modeling, as well as it's coverage of the new methods for dealing with the limitations that neural nets have made available.

The third section of the sleeve is done. #tattoo #saturn

In a moment of defeat, the brain undergoes a sudden shift. The neuroscientist Misha Ahrens (left) and his student Alex Chen showed that cells called astrocytes help to shift the brain state from hope to hopelessness. www.quantamagazine.org/once-thought...

This also appears directly related to the challenges discussed in my previous repost since LLMs are modelled after networks of neurons, and this article is about an important network in the brain that runs parallel to the networks of neurons for which an LLM has no analog.

The raw interactions quoted here with what the article calls a misaligned LLM are disturbing. But to see this behavior being studied at this level is encouraging.

My #tattoo is slowly progressing.

The “MaxCut” problem is a fundamental question about graphs with real-world applications, like efficient circuit design. Recently, work on MaxCut helped mathematicians solve a major problem in number theory. www.quantamagazine.org/networks-hol...

The brain is busy even when you’re just zoning out.

In quantum physics, even nothingness can be infinite. @georgemusser.com explains: www.quantamagazine.org/in-quantum-m...

I'm a few months behind, but is still worth a listen now. That sample container is prepped and ready to be picked up. It is expensive to do so, but it's also a sample that will aid our understanding of the origins of life if we could get it from there to here. open.spotify.com/episode/0xtK...

A rare in person session today (we usually play online). #dnd #dwarvenforge

I'm so new to this platform that I know no one here who cares, but nonetheless the first step of some tattoo work that's been in the planning stages for months was done this week. Hannah is amazing. #tattoo #seagullnebula #skullandcrossbonesnebula #m41 #m93 #sirius #canismajor

The math of infinity is now plugged into the math of computer networks www.quantamagazine.org/a-new-bridge... .

A random thought...it is maybe in some respects unfortunate humans have mostly settled on base 10 as our number system. For quick, intuitive do-it-in-your-head math, I suspect base 12 is better.
