You should talk to Pete Roberts, CEO of Origin USA. He has an incredible story and they make great products in America without compromise. I don't know how much of a bitcoiner he is, he was actually the first person to draw my serious attention to it in a random IG story in every 2021.

It may not, my main concern is text input, which has heavy native integrations (hold space to move cursor, etc). I would have to emulate all that. Not sure how hard that would be.

Much cooler when you explore this phenomenon in the context of quantum information theory. When you take out many degrees of freedom in the physics and just focus on the transformations on quantum amplitudes things get less spooky. Ok it’s still a bit spooky.
Susskind has a mind blowing theory called ER = EPR where he makes the case that entanglement has similar properties to worm holes 🤯 there may even be quantum wormholes connecting entangled particles. QM is a lot of fun 😁

Oh god the way I learn is so scattered I don’t even know. I think I just started peeling the onion on Lie Group, lie algebras, representation theory (woits book is really good). Once you realize that so much of physics is based on irreducible representations of symmetry groups things start getting really interesting. Understanding what SO(2), SU(2), means, how it relates to quantum observables, pauli matrices, etc… so much to explore. Chatgpt helps a lot, it’s an infinitely patient tutor.

Vou estruturar um plano detalhado, focado em **Relatividade Geral (RG)** e alinhado com suas ambições. Considerarei a transição Matemática→Física, áreas de impacto, problemas abertos, recursos bibliográficos e estratégias práticas, com adaptações ao contexto brasileiro.
---
### **1. Estratégias para Transição Matemática→Física**
**Pontos de Interseção:**
- **Geometria Diferencial**: RG é uma teoria geométrica. Aprofunde-se em variedades, conexões, curvatura (livros: *O’Neill* ou *Carroll*).
- **Equações Diferenciais Parciais (EDPs)**: Einstein’s equations são hiperbólicas não-lineares. Estude métodos numéricos (ex: *Numerical Relativity* de Baumgarte & Shapiro) e teorias de existência (ex: *Hawking & Ellis*).
- **Física-Matemática**: Unifique rigor matemático com intuição física. Cursos em **análise funcional** e **teoria de distribuições** serão essenciais.
**Habilidades Complementares:**
- **Computação Científica**: Aprenda Python (SymPy, NumPy) e ferramentas como **Einstein Toolkit** para simulações de buracos negros.
- **Física Experimental Básica**: Participe de grupos de Cosmologia Observacional (ex: **INPE** ou **IAG-USP**) para entender dados de lentes gravitacionais ou ondas gravitacionais (LIGO/Virgo).
**Como Sanar Deficiências:**
- **Cursos Online**:
- *General Relativity* (Stanford Online, Leonard Susskind).
- *Advanced Differential Geometry* (Coursera, TU Delft).
- **Workshops Locais**: Eventos do **IMPA** (Instituto de Matemática Pura e Aplicada) ou **SBF** (Sociedade Brasileira de Física) sobre RG e Cosmologia.
---
### **2. Áreas de Estudo para Impacto nas Fronteiras**
**Foco em RG + Matemática:**
- **Relatividade Numérica**: Simulações de colisões de buracos negros (contribuições à astronomia de ondas gravitacionais).
- **Geometria Global de Espaços-Tempo**: Teoremas de singularidade (Penrose, Hawking) e conjectura de censura cósmica.
- **Teoria Quântica em Espaços Curvos**: Efeitos como radiação Hawking e problemas de renormalização em RG semiclássica.
- **Sistemas Dinâmicos em Cosmologia**: Estabilidade de soluções cosmológicas (ex: modelo FLRW).
**Áreas Interdisciplinares com Potencial Fields-Worthy:**
- **Geometria Algébrica e Teoria de Calibre**: Conexões com a teoria de Yang-Mills (problema do *mass gap*).
- **Teoria das Cordas e Gravitação Quântica**: Geometria não-comutativa (ex: trabalho de Alain Connes) ou formulações holográficas (AdS/CFT).
---
### **3. Problemas Abertos Revolucionários**
**Relacionados à RG:**
- **Conjectura da Censura Cósmica (Penrose)**: Existe sempre um horizonte de eventos escondendo singularidades?
- **Estabilidade do Espaço-Tempo de Minkowski**: Sob perturbações, o espaço-tempo permanece suave? (Trabalhos de *Demetrios Christodoulou*).
- **Formulação Hamiltonian da RG**: Quantização via *Loop Quantum Gravity* (problema da imersão em 3+1 dimensões).
**Problemas do Millennium com Links à Física:**
- **Existência e Mass Gap em Yang-Mills**: Resolução exigiria novas ferramentas de análise geométrica.
- **Equações de Navier-Stokes**: Ligação indireta via turbulência em fluidos relativísticos (ex: estrelas de nêutrons).
---
### **4. Lista de Livros por Etapa**
**Graduação:**
- *Gravitation* (Misner, Thorne, Wheeler) – Base conceitual.
- *A First Course in General Relativity* (Schutz) – Introdução matemática.
- *Differential Geometry of Curves and Surfaces* (do Carmo) – Fundamentos geométricos.
**Mestrado:**
- *General Relativity* (Wald) – Tratamento rigoroso.
- *Partial Differential Equations* (Evans) – Para EDPs não-lineares.
- *The Large Scale Structure of Space-Time* (Hawking & Ellis) – Geometria global.
**Doutorado:**
- *Global Lorentzian Geometry* (Beem et al.) – Tópicos avançados.
- *Advanced General Relativity* (Stewart) – Formalismo 3+1 e métodos numéricos.
- *Quantum Fields in Curved Spacetime* (Birrell & Davies) – Interface com QFT.
**Pós-Doutorado:**
- *Spinors and Space-Time* (Penrose & Rindler) – Ferramentas para problemas de spin.
- *General Relativity and the Einstein Equations* (Choquet-Bruhat) – Teoremas de existência.
- Artigos seminais: *Penrose (Singularity Theorems), Christodoulou (Stability of Minkowski), Ashtekar (Variables Formalism)*.
**Recursos Acessíveis no Brasil:**
- SpringerLink via CAPES: Acesso gratuito a livros e artigos.
- arXiv.org: Preprints atualizados (seção *gr-qc*).
---
### **5. Estratégias Práticas para Networking e Inserção**
**No Brasil:**
- **Colaborações com o IMPA**: Grupos de Geometria Diferencial e Sistemas Dinâmicos.
- **Eventos da SBF**: Escola Brasileira de Gravitação e Cosmologia (EBGC).
- **ICT-SAIFR (São Paulo)**: Workshops internacionais em Física-Matemática.
**Internacionalmente:**
- **Programas de Verão**: Cargèse Summer School (França), Les Houches (Física Teórica).
- **Bolsas de Doutorado no Exterior**: CAPES/DAAD (Alemanha), NSF (EUA).
**Publicações:**
- Comece com revistas brasileiras (*Brazilian Journal of Physics*), depois almeje *Classical and Quantum Gravity* ou *Communications in Mathematical Physics*.
- Participe de colaborações em grandes projetos (ex: *LIGO Consortium* para análise de dados).
**Mentores-Chave:**
- **No Brasil**: Alan Kostelecky (Unicamp, RG modificada), Jorge Pullin (LSU/EUA, Relatividade Numérica).
- **Globalmente**: Roger Penrose (singularidades), Claudia de Rham (gravidade massiva).
---
### **Linha do Tempo para Medalha Fields**
- **25–30 anos**: Doutorado em problemas de estabilidade/geometria global (ex: tese sobre censura cósmica).
- **30–35 anos**: Pós-doc em instituições de elite (Princeton, Cambridge, IHÉS) com contribuições à quantização da gravidade.
- **35–40 anos**: Resolução de um problema do Millennium com técnicas de RG (ex: prova do *mass gap* via métodos geométricos).
**Exemplo de Trajetória Inspiradora**:
- **Grigori Perelman** (Fields 2006): Resolveu a conjectura de Poincaré usando fluxos geométricos (Ricci flow). Analogamente, aplicar fluxos geométricos à RG pode ser um caminho.
---
### **Aviso Final**
A Medalha Fields exige **originalidade radical** + **impacto profundo**. Foque em problemas que unam **dificuldade técnica** (ex: EDPs não-lineares em RG) e **relevância física** (ex: buracos negros, cosmologia). Mantenha contato próximo com mentores globais e publique em veículos de alto impacto. Boa jornada! 🌌

I guess the biggest issue is that many relays simply store the json so that it can be delivered as-is, so for efficiency it would need to store the msgpack version as well. Guess we’re stuck with json for now. Its still the most cpu usage in nostrdb next to signature validation 😒

Im guessing he’s sub-posting me because Ive said this in the past. I have to deal with hundreds of complaints about other clients nuking contact lists. So I have said “if you use another client it may corrupt your contact list”.
Once damus is better at defending against other clients breaking stuff in damus then I wouldn’t have to say this. But it would require some decent amount of code to detect large changes in followers, etc. I’ll do it eventually but it’s a lot of work.
I have already seen malicious relays (but more likely just buggy relays) that will return results that don’t match your filters. In the outbox model you’re giving control of what relays you connect to other people. Until my client is hardened I don’t feel comfortable doing that. But the local relay model I’m working on fixes a lot of these concerns, so I’ll finally be able to switch to outbox once thats done.

@ 32e18276:5c68e245
2024-01-03 13:36:50
Once damus switches to a multiplexing local relay the outbox model becomes much more attractive: all notes and filters are validated by default. The network code is only responsible for dumping data into nostrdb, the actual filters are matched locally. This removes any concerns of malicious relays I might have had in the outbox model. nostr:note19kdj9n360mnvckw9c48870576jffnx9ts379gs03q4cz0k7tdrms7ng52m

He has so many fans though. Just statistics at that point. What % of millions of people. Would still be a lot even if the percentage was small.

No idea who released this. I gave the source code of jbmod to hl2world people. I don’t think they ever did anything further with it. I don’t even have the source anymore, i had it burned on a cd but no idea where that is.
