I've been very careful in how I approach pixelfed development in regards to Instagram and their ToS/trademarks.
This is why you can't crosspost, or otherwise access IG apis via Pixelfed.
They are grasping at straws at this point, along with banning Pixelfed urls, this behavior is desperate.
We must be doing something right 😉
Climate startup Make Sunsets releases toxic chemicals into the atmosphere to block the sun, alarming scientists

> #injecting large amounts of #particles into the #atmosphere would not undo the effects of increasing carbon dioxide levels, but rather create #another #climate scenario. It might bring down temperatures but would not, eg, reduce ocean acidification. The #consequences for precipitation and wind patterns are #unknown.
> There are currently #nolaws or treaties that #regulate weather #modification or #climate #engineering and I’m afraid we will in the future see more companies doing this.

Compiling my yearly top-papers list and "MaxViT: Multi-axis Vision Transformer" should probably make the cut.
MaxViT is a vision transformer with local-global interaction between visual tokens within a single block.
The so-called multi-axis attention scales linearly (vs quadratic complexity in the original ViT).
You can use it for
- classification
- object detection
- instance segmentation
and generative modeling.

A common or harbour seal pup, admiring its reflection in the calm waters of the sea loch.
Actually it was waiting for high tide before swimming off, but the image suggests otherwise.
The birth of these seals is helpful for the white-tailed eagles here on Mull, as the eagles make a meal of the afterbirth, and because they're messy to eat often makes their white tails, red.

> One of the central problems in fluid dynamics is to figure out if the [Euler] equations ever fail, outputting nonsensical values that render them unable to predict a fluid’s future states.
> Mathematicians have long suspected that there exist initial conditions that cause the equations to break down. But they haven’t been able to prove it.
> In a preprint posted online last month, a pair of mathematicians has shown that a particular version of the Euler equations does indeed sometimes fail.
...
> Perhaps in some situations, the equations will proceed as expected, producing precise values for the state of the fluid at any given moment, only for one of those values to suddenly skyrocket to infinity. At that point, the Euler equations are said to give rise to a “singularity” — or, more dramatically, to “blow up.”
> Once they hit that singularity, the equations will no longer be able to compute the fluid’s flow.

Very important and interesting work, if you're a mathematician, a physicist or an engineer that has ever 'crashed' with Euler/Navier-Stokes equations.

For freely available online textbooks on a variety of courses, LibreTexts is a great resource, especially to begin exploring a subject.
They're mostly accessible to non-specialists and have many advanced features: https://libretexts.org/advanced.html

Astronomy and Cosmology: https://phys.libretexts.org/Bookshelves/Astronomy__Cosmology
Physics: https://phys.libretexts.org/Bookshelves
Math: https://math.libretexts.org/Bookshelves

How #things #change .
No one asks who is John Galt any more.
The question now is: Who is John Mastodon?
#johngalt #johnmastodon
(Yes, I just created a tag for the new mysterious John.)

> The Consolation of Haldane depends, though, on what kind of universe we live in, and maybe on such arcana as whether there's enough matter eventually to reverse the expansion of the universe, and the character of vacuum fluctuations. Those with a deep longing for life after death might, it seems, devote themselves to cosmology, quantum gravity, elementary particle physics, and, especially, transfinite arithmetic.
-- Carl Sagan, Demon Haunted World
Sagan does not agree with Haldane, but I think "why not?"

New book day! After a couple of intense year's my partner's book is now out in the wild, UK & US publications.
'Escape From Model Land, how mathematical models can lead us astray and what we can do about it'
With models (financial, environmental, public heath etc) so influential in our lives this entertainingly written book is really important for modellers themselves and decision makers increasingly reliant on models.

What are the biggest mysteries in fundamental physics? And what, exactly, is fundamental physics? How important is it? I gave a talk about all that, and here's the video:
Plus, I give a quick intro to the Standard Model of general relativity. Instead of just waving my hands about curved spacetime, I explain Einstein's equation.
Slides are here:
