"Heredamos este legado del terror de lo que se nos ha quedado en el cuerpo de lo que fue esa España y es necesario recuperar también el legado de resistencia". La Ruta al Exilio es un recorrido de jóvenes por los rincones de nuestra memoria. Han estado en Andalucía en lugares cargados de historia y de dolor, pero también de dignidad y hemos hecho un diario de viaje con ellos. Un programa especial para celebrar el 95 aniversario de nuestro #14ABRIL: youtu.be/TwzNwTi6O1c

¿Qué efectos tuvo la regularización de 600.000 inmigrantes en España en 2004? 1⃣No tuvo efecto atracción. 2⃣Aumentó empleo formal de inmigrantes. 3⃣No afectó empleo nativos. 4⃣Aumentaron ingresos públicos en 4.000€ por inmigrante, sin aumentos de gasto público significativo.

MIT researchers have been digging into the "brains" of 60 different scientific AI models, and have stumbled upon something wild. It turns out, whether an AI is reading text or looking at 3D atoms, they are all starting to agree on the same hidden truth about our universe. Here is the pattern you can't unsee. 🧵 1/ First, the premise. We have AI models for everything now. • Some read protein sequences (like text). • Some look at 3D crystal structures (like vision). • Some predict forces in materials. They are built differently. They are trained differently. They should think differently. 2/ But a new paper from MIT just asked a massive question: "Are these models actually learning the same physics?" The answer is yes. And it’s kind of spooky. 3/ The researchers took nearly 60 models—from LLMs reading SMILES strings to complex 3D potentials—and peered inside their latent spaces (their internal "thoughts"). They found that as models get smarter, their internal representations of matter start to look identical. 4/ Think of it like this: If you ask a poet and a physicist to describe a sunset, they use different languages. But if they are both experts, they are describing the exact same reality. The AI models are converging on a "Universal Representation of Matter." 5/ This chart in the paper is the smoking gun. It shows that an LLM (trained on text) and a 3D Atomistic Model (trained on geometry) align almost perfectly when looking at molecules. The text model "hallucinated" the 3D structure implicitly. It learned the physics just by reading the chemistry. 6/ But that's not even the most interesting part. This convergence gives us a new way to spot "fake" intelligence. The researchers found that high-performing models all cluster together in this "truth" space. But the weak models? They scatter. 7/ It’s the Anna Karenina principle of AI: "All happy (smart) models resemble one another; every unhappy (dumb) model is unhappy in its own way." If a model diverges from the pack on standard data, it hasn't learned a new trick. It’s just lost in a local sub-optimum. 8/ However, there is a catch. When the researchers threw "out-of-distribution" data at the weak models (stuff they hadn't seen before), the behavior flipped. Instead of scattering, the weak models collapsed. They all started making the same low-information mistakes. 9/ This reveals a massive problem in Materials Science AI specifically. The study shows these models are currently "data-governed." They are memorizing their specific training sets rather than learning universal laws. They aren't "foundational" yet. They are just really good parrots. 10/ So, what does this mean for the future of Science? Efficiency: We don't need massive, expensive, symmetry-enforcing architectures. We can "distill" the knowledge from big models into simple, fast ones. Truth: We can use "alignment" to fact-check AI. If a model disagrees with the consensus of other top models, it's likely wrong. 11/ The most profound takeaway? pattern-matching And the fact that different AIs are independently deriving the same laws suggests that these models aren't just pattern matching. They are uncovering reality. 12/ If this research holds up, in 5 years we won't distinguish between "protein models" and "materials models." We will just have "Matter Models." One foundation to simulate it all. 13/ This paper is a dense but rewarding read. It fundamentally changes how I think about "generality" in AI.

My passport is being detained at the Netherlands 🇳🇱 Embassy in Kampala 🇺🇬. Last month I applied again for the Netherlands visa because I am supposed to give a keynote speech at the International Fundraising Congress even after refusing my first visa request for the same event. But even after applying again, the embassy has refused to respond to my calls and emails since I submitted my new application and the event is happening next. The embassy of the Netherlands rejected my first visa request because they did not believe I had enough ties to Uganda to ensure my return after the event. They also believed that I would stay in their country because of the current political situation in Uganda 🇺🇬 However, I have a UK 🇬🇧 visa activating on November 4th, and I am scheduled to speak at another event in London. And my USA visa is still valid till mid 2024. When I contacted the embassy in Kampala, they informed me that they are not the ones who make visa decisions and that all decisions are made in Hague, Netherlands. They suggested that I could appeal by shipping my passport to the address listed in the refusal letter. However, there was also an option of applying again, so I decided to do so. To my surprise, VFS Global sent me an email stating that my passport had been sent to the Netherlands embassy in Kampala which contradicted what the embassy had said that the decisions are not made by them. (Lies) It has been over 15 working days, and I am still waiting for my passport. I need it to attend the conference next week, but no one is responding to me. This situation is unfair since the embassy is trying to delay my passport and try to deny me a visa without any clear reason. As an activist, I feel silenced without any clear reason. This was my second time applying for this visa, and I made sure to provide everything they needed. It is not fair that we have to spend a lot of money applying for a Schengen visa only to be denied because the consular is not motivated as my role is to motivate unmotivated people. I have already lost money twice in two different months. I would greatly appreciate any assistance from the people on this platform. I have also tagged everyone who works at the Netherlands 🇳🇱embassy including the ambassador. at least let them be open and explain why am not being allowed to go and speak at this conference. @NLinUganda @Karin_Boven @JantienZ #netherlands #visa #embassy

So very true Have you ever thought about this? In 100 years like in 2123 we will all be buried with our relatives and friends. Strangers will live in our homes we fought so hard to build, and they will own everything we have today. All our possessions will be unknown and unborn, including the car we spent a fortune on, and will probably be scrap, preferably in the hands of an unknown collector. Our descendants will hardly or hardly know who we were, nor will they remember us. How many of us know our grandfather's father? After we die, we will be remembered for a few more years, then we are just a portrait on someone's bookshelf, and a few years later our history, photos and deeds disappear in history's oblivion. We won't even be memories. If we paused one day to analyse these questions, perhaps we would understand how ignorant and weak the dream to achieve it all was. If we could only think about this, surely our approaches, our thoughts would change, we would be different people. Always having more, no time for what's really valuable in this life. I'd change all this to live and enjoy the walks I've never taken, these hugs I didn't give, these kisses for our children and our loved ones, these jokes we didn't have time for. Those would certainly be the most beautiful moments to remember, after all they would fill our lives with joy. And some of us waste it day after day with greed, selfishness and intolerance. Every minute of life is priceless and will never be repeated, so take time to enjoy, be grateful for, and celebrate your existence.
