Esse é o fogo-fátuo (também conhecido como Mãe do Ouro), um fenômeno luminoso natural observado na Paraíba e em outras regiões do Brasil.

• Características: Aparece como uma esfera dourada ou chamas coloridas (azuladas/esverdeadas) que flutuam silenciosamente, mudam de tamanho e desaparecem de repente.
• Locais comuns: Pântanos, cemitérios, mangues, áreas úmidas com matéria orgânica em decomposição, minas abandonadas e matas.
• Explicação científica: Resulta da combustão espontânea de gases (principalmente metano e compostos de fósforo) liberados pela decomposição orgânica.
• Folclore e crenças populares: Muitos o interpretam como algo sobrenatural — almas perdidas, espíritos, guardiã de tesouros ou aviso de perigo. Há relatos em Goiás, Minas Gerais e interior do Brasil.
• História: Fenômeno conhecido há séculos tanto no folclore brasileiro quanto europeu.

É um clássico exemplo de como um evento natural ganhou forte conotação mística na cultura popular.

MIT just built an AI that can control your body.
It can move your fingers, make you play piano, even if you don’t know the song!
AI decides the hand movement. Wrist pads send signals to your muscles, so your fingers move even if you don’t know how

We built an interactive 3D module to teach kids about what temperature does to water.

- You adjust the temperature in real time
- You see the impact on the state of water and what's changing at a molecular level
- You can unlock two secret states in there if you pass a quick quizz

This is the first of a giant series. We're turning the open source @withmarbleapp curriculum into a full bank of these interactive lessons. One for each topic kids learn in primary school.

If you are a parent or primary school teacher, let us know in comments which module you want to see next.

「その待ち時間が学校の大部分だ。1年間の教室数学は約150時間の指導だが、大半がペース調整、復習、再指導に費��される。」😭

A third grader just scored a 5 on AP Calculus BC. The system that trained him contains no LLM. The core is a knowledge graph one man spent 250 hours encoding by hand, two minutes per edge.

The platform is Math Academy. Its "AI" is an expert system that routes each student through nearly 3,000 math topics, from 4th grade arithmetic to the math behind machine learning. Every node, every prerequisite link, every weight was placed manually by a team of mathematicians.

The weights alone took Justin Skycak a full month: 1,500 topics at the time, roughly 5 prerequisite links each, 2 minutes to estimate each one. 8 hours a day of pure encoding, done before ChatGPT existed to ease the load.

Why go through that? Because the graph unlocks mastery learning, the closest thing education research has to a cheat code. In 1984, Benjamin Bloom showed that students with one-on-one tutoring perform two standard deviations above a regular classroom. The average tutored kid beats 98% of the lecture hall.

Nobody could afford a tutor per child, so the finding sat in journals for 40 years. A prerequisite graph with a mastery gate is the workaround. The system always knows the exact next topic a specific kid is ready for, drills it until proven, then moves on. Zero time spent waiting for 29 classmates.

That waiting is most of school. A year of classroom math is roughly 150 hours of instruction, and the majority goes to pacing, review, and re-teaching. Strip it out and a motivated kid covers six grade levels in one calendar year.

The origin makes it better: this grew out of a math program at Pasadena High School where 8th graders were passing AP Calculus BC, back when the founders were still hand-grading the whole thing.

The most effective education AI running today is a graph a few humans built by hand, one edge at a time.

Following the amazing reaction to the Marble Curriculum yesterday, we've decided to make it open source 🛰️👇

Everything a child learns in primary school. 1,590 concepts. 3,221 connections across 8 subjects, from Math and Science to Computing and Life Skills. Anchored in the US and UK curriculums, standard by standard (NGSS, Common Core, DfE).

What you will find in the repo: every concept as structured JSON with its age band and the evidence a child must show to master it. Every prerequisite link marked hard or soft, with a written rationale. It's a true DAG you can compute learning paths on. Open license, you can build whatever you want with it.

Now is a unique time in history to be building in education. Getting AI and kids education right is likely one of the hardest and most important problems to crack over the next decade and we need as many smart and creative minds behind it.

We think a common solid basis, accessible to all and that can be built upon, is critical to move fast. That's why we're making this curriculum open source.

It's not perfect but we know it's a robust basis, and we believe that sharing it openly is the fastest way to progress in this field. If you're building in education, share this around you and tell us in comments if you find this useful and if you want to contribute.

We'll keep working and investing on it @withmarbleapp. Credit goes to @guillaume_boni for building this. I just made it look pretty.

Alpha School made a groundbreaking change to how we teach kids academics that every school should copy

They started A/B testing every piece of learning material to give kids the most effective materials for every topic

To accomplish this, they needed to divorce mastery tracking from curriculum. They needed to build a "routing" layer that has independent diagnostics/assessment in order to be able to run these A/B tests

We're taking this one step farther at Recess; our product has a recursive/self-improving loop similar to how tiktok works.

We're building an independent assessment and tracking layer, and then using classic ML-based-recommendation systems to show kids content for each node. This will automate the A/B tests and also allow different kids to get different types of content based on what will perform the best for them, vs. having one population-level curriculum that all kids follow.

It's a bit like the difference between a cable television network and Youtube. Cable television creates a "program schedule". There's a set playlist of shows coming up and you follow that. Alpha is a GREAT network cable show; think HBO.

Our approach looks more like HBO Max or Netflix or Youtube; we still syndicate all that amazing content, but every user is recommended slightly different content that makes sense for them. Not all users will see the same content; some will get content that no one else on the platform gets
