> #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.

Excuse my intrusion.
It's a rather interesting article, very challenging, as someone puts it.
However, I don't think any AI will ever be able to write code to solve a puzzle. 😉

> 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.

An idea taken from Jules Verne's From the Earth to the Moon.

You can do a poll here.
It's the second icon counting from the left, when you create the too. (When you hover it is shows "Add a poll"... just in case you're ambidextrous ;)

Cool. I see one of your 'friends' is Math Jax. 😎

@charlottekl
Still, some of my best friends are physicists. 😉
