Will @OpenAI and @AnthropicAI ever crack this one?

Behind this beautiful turbulence cascade lies a Millennium Prize Problem:

For the 3D Navier-Stokes equations, nobody has proved whether every smooth flow remains smooth forever or whether a singularity can form in finite time.

Exciting news for #QGIS users! The "Google Earth Engine Plugin for QGIS" is now updated with new no-code tools that allow you to download and use #EarthEngine datasets in QGIS easily. Check out my newly contributed tutorials for the latest plugin (1/n) 👇

[Valerie Pasquarella @valpasq]

What a week! 🚀🛰️❤️

Very excited the #SatelliteEmbedding dataset is now available in the #EarthEngine Data Catalog 🌎👀 — ICYMI learn more here: https://t.co/SRY1eCBA4Y
(+ a small grants opportunity for researchers! 🧑‍💻)

Can’t wait to see how you use it! 🗺️⚙️

Google's new foundation model is a big leap in making earth observation data useful and enabling novel use cases. I collaborated with @GoogleDeepMind and @googleearth teams to develop use cases and official tutorials for satellite embedding dataset in #EarthEngine. A thread👇 1/n

If you use Leaflet/Folium, or one of Mapbox libraries developed by @mourner, appreciate how it's being developed and do what you can to stop this madness caused by Russia

This is how nearly every night sounds for me and my family — imagine getting used to that, living, working, raising kids. A lesson the world didn’t learn from WW2: when you tolerate and appease evil, it grows stronger, and you won’t notice until it reaches your home.

[Illia Ponomarenko 🇺🇦 @IAPonomarenko]

One day, our children will become journalists and historians, I hope, and they will look back on our era from the distance of time—and they will be shocked at how exceptionally weak, pitiful, and incompetent the leaders of what was still called the free world were in the face of an utterly brazen and unpunished evil that, night after night, was openly bombing Kyiv and killing people on a massive scale.

[Volodymyr Zelenskyy / Володимир Зеленський @ZelenskyyUa]

Tragically, three-year-old Tymofii died in the hospital today. Seven-year-old Radyslav. Arina, who will forever be seven as well. Nine-year-old Herman. Fifteen-year-old Danylo. Fifteen-year-old Mykyta. Fifteen-year-old Alina. Kostiantyn, who will forever be sixteen. Nikita – seventeen. These are the children killed by a Russian ballistic missile strike on Kryvyi Rih. There were only a few minutes after the missile was launched from the enemy’s Taganrog area. Unfortunately, nine adults were also killed. My condolences to all the families and loved ones.

The missile struck right at the ordinary street with residential buildings, a playground, shops, and a restaurant around. Sixty-two people were injured in the attack, including twelve children. Some of them are in critical condition, they are currently in the hospitals. Doctors are doing everything possible to save lives.

In addition to that ballistic missile, the Russians launched attack drones against Kryvyi Rih yesterday during the rescue operation – in time of such grief for people. The drone attack injured seven people. One person was killed. There is simply no deeper level of cynicism, vileness, or hatred toward people than what Russia embodies today.

It is critically important not to leave this Russian strike on civilians, on the city – every such strike – without a response from the world. Kryvyi Rih and all of Ukraine have already been supported by many yesterday and today. I am grateful for the principled stance of the foreign ministers of the Czech Republic, Finland, Lithuania, Latvia, Estonia, and Austria. I thank the High Representative of the European Union for Foreign Affairs and Security Policy for her position and support. We value the principled statements made by the Embassies of Japan, the United Kingdom, Switzerland, and Germany. Unfortunately, the response from the U.S. Embassy is surprisingly disappointing – such a strong country, such a strong people, and yet such a weak reaction. They are afraid to even say the word “Russian” when speaking about the missile that murdered children.

Yes, the war must end. But to end it, we must not be afraid to call things by their names. We must not be afraid to pressure the one who continues this war and ignores all the world’s proposals to end it. We must pressure Russia – the one choosing to kill children instead of choosing a ceasefire. There must be additional sanctions against those who cannot exist without ballistic strikes on their neighboring nation. We must do everything in our capacity to save lives.

And we have discussed this, in particular with the American side, the additional air defense systems supply to defend against precisely these types of missile attacks. We count on our agreements with the President of the United States, who promised to help find more Patriots. And we count on the strength of the world to overcome this evil – this war, this Russian aggression.

Only through strength and coordinated action with partners can we stop the killing, save the lives of children, and establish lasting peace. I thank everyone who stands with Ukraine – from the very beginning of this war, and especially on such tragic days.

Eternal memory to all our people whose lives were taken by Russian strikes.

@FT A flock of birds may not cause damages like this. What "early media sources", this FT article looks misleading. https://t.co/1Jq1lQwia5

@MykolaKozyr @Esri Thanks! Changed it to public, should be visible now.

[Gennadii Donchyts @gena_d]

It takes just a few lines of code to combine @ESRI ArcGIS Maps JavaScript code and Earth Engine. Can be used for example to query EE raster processing on-the-fly: https://t.co/Pjf4Zcnd8y. The animation code here is from ESRI docs, I only added a static S2 composite (not animated)

[Gennadii Donchyts @gena_d]

@Esri It would be good to make the composite images also time-dependent. Some new building footprints seems to be missing in the vector map.

The Google Earth Engine team has an opening for a Developer Relations Engineer, based either in NYC or Mountain View, CA! Please see https://t.co/PdGCjcsAkQ

Pass this opportunity to your network, especially to people who have experience working with Earth Engine and REDD+/MRV.
