A modern-day Trojan Horse.

En política, como en medicina, hay que intentar ante todo no hacer daño. Una serie de acciones desesperadas, erráticas, sin fundamento ni propósito claro, es más el daño que hacen que el bien que procuran.

Los venezolanos hemos sido víctimas de un régimen terrible, pero también de una dirigencia opositora que demasiadas veces ha apostado por atajos que terminaron fracasando.

"I present the case for total opposition to the use of artificial intelligence in mathematics."
= a view you don't often hear on X. But I am looking forward to reading it carefully, and if you care about math and AI, I encourage you to do the same. arxiv.org/pdf/2608.02859

What do polar coordinates, polar matrix factorization, & Helmholz decomposition of a vector field have in common?
All are implied by Brenier’s Thm: a cornerstone of Optimal Transport theory. It’s a fundamental decomposition result that’s not widely known

If you sandwich a ball between two parallel planes, it will roll perfectly. But surprisingly, smaller, pointier shapes can do this too.

Every angle of this triple play started by Zach Neto on a line drive from Shohei Ohtani 😮💨

The Helmholtz decomposition is one of the fundamental results of vector calculus.
It says any well-behaved vector field can be split into two parts, one capturing sources and sinks through divergence, and one capturing rotation through curl.

Bacteria move around using a molecular machine called the flagellar motor that rotates faster than the flywheel of a race car engine and switches directions in an instant. After 50 yrs, scientists have finally figured out how it works. “My lifelong quest is now fulfilled.” Link⤵️

The most f*cked up aspect of this is the "DoorDash grandma" t-shirt she's wearing, and the implications of this: I checked and this is a pre-organized PR stunt between DoorDash and the White House (they boast about it on their website: about.doordash.com/en-us/new…).
The lady - Sharon Simmons, "a grandmother of ten" who has "completed more than 14,000 deliveries" - isn't even from DC, they brought her over from Arkansas as a prop for this.
Think about just how uniquely rotten things need to be in order for this to happen.
She is literally a grandmother relying on gig work because she can't afford healthcare for her husband's stage-3 cancer. She doesn't even get paid a living wage and needs to rely on tips. And as an "independent contractor," she gets no benefits, no healthcare, no retirement.
Which means she is an almost perfect illustration of the failure of the American social contract on almost every level: healthcare, labor rights, retirement, wages, etc. Any decent human being looking at her story - let alone policymakers - should feel only one thing: shame.
Yet DoorDash and the White House looked at this woman and saw a photo op. They flew her from Arkansas, branded her "DoorDash grandma" and used her as a mascot for a tax tweak - no tax on tips - that wouldn't even begin to cover her husband's chemo sessions.
Watching the actual video of her "delivery" to Trump (pbs.org/newshour/politics/wa…) is almost unreal. Trump opens up by saying, smiling at the camera, "who says it looks staged? It doesn't." They immediately proceed to do a joint press conference to a bunch of journalists who were conveniently standing right there.
None of the questions that follow during the next 15 minutes are related to Simmons' situation who just stands there. Journalists, the President, and cameras all obsessing over culture wars and the actual war in Iran, while the walking embodiment of the country's deepest structural failures - healthcare, labor, retirement - stands silently in a corporate t-shirt, unmentioned and too uncomfortable to confront.

In the West, you see Israel through the prism of their unrelenting mendacious propaganda.
On the ground, you see it in its raw form: a vindictive, bitter, vicious, ungrateful, unreliable, perfidious, and, mainly, bloodthirsty terrorist state.
Enough, no?

Justo hoy, Netanyahu lanza su ataque más duro contra el Líbano desde que empezó la ofensiva.
Su desprecio por la vida y el derecho internacional es intolerable.
Toca hablar claro:
- Líbano debe formar parte del alto al fuego.
- La comunidad internacional debe condenar esta nueva violación del derecho internacional.
- La Unión Europea debe suspender su Acuerdo de Asociación con Israel.
- Y no debe haber impunidad ante estos actos criminales.

Is there anybody who does not see that Trump is mentally sick?

This picture is enough to draw the shape of the magnetic field lines of the planet. Can you do it?
We see our home planet as a whole, lit up in spectacular blues and browns. A green aurora even lights up the atmosphere. That's us, together, watching as our astronauts make their journey to the Moon.
ALT A full disk image of Earth, as seen from the Orion capsule. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. From about 8 to 9 o'clock, a large brown landmass is Africa, with the Iberian peninsula twinkling with lights just where the planet curves. At the 1 o'clock spot, aurora glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space. Credit: NASA/Reid Weisman

4 people are in there with hopes, dreams, risk and the unknown.
It makes me breathless, knowing how they're feeling and what they're facing.
So exciting to see what we're capable of when we work together in common purpose, deciding to push back the edges of our collective ignorance.
Have a great voyage, crew of @NASAArtemis!
