A question for all the Bitcoin dads out there in this digital space…
Tonight, my 3-year-old daughter suddenly said she misses her grandma and granddad.
The thing is she only saw my mom once. And she never met my dad.
He died when I was 17.
My mom passed away last year. She was too sick to meet her granddaughter.
A few weeks ago my daughter saw a photo of my dad and asked who it was. I said, “That’s my dad. Your granddad.”
She asked “Where is he?”
I told her, “He’s no longer on this planet. He died. He’s somewhere in this universe.”
And tonight… out of a sudden.
It hit her.
And then it hit me too.
We cried together. For a full hour.
She missed the people she never got to know. And I missed the people I can never see again.
We just hugged. And cried.
I honestly don’t know how to talk about death with a 3-year-old.
I just tried to be there. To feel it all with her.
Now we’re both exhausted. Going to bed.
Current block 893720.
If any of you dads out there have been through this, done that…
If you’ve got thoughts, words, or just a story idk I’d appreciate it.
GN Bitcoin fam 😴 Thanks for reading.

Ok, now I know what my new favorite mushroom is!
An awesome kid I met once told me that I talk like I swallowed Wikipedia, so I would love to actually find out what that tastes like 😂
鸡枞 is apparently Collybia albuminosa and it goes on my food bucket list 🍄🟫
I’m really sad that when I was in Yunnan I didn’t eat more wild mushrooms. I saw people gathering them, and posters about them, but never spotted opportunities to eat any 😢

Anyone that is not happy living in the US is welcome to leave. The fact that almost no one does and millions of people risk their lives to come here and millions more are waiting in line to come here legally tells you what you need to know. Not all nations can come out victorious in conflict, but only nations can.
How is it an oxymoron? Do families, clubs, companies not have governance?

I don't understand this entire debate. All computer logic is integer-based.
1224 satoshis is the same number as 0.00001224 Bitcoin. That's just two different formats for writing it, the same way that $10.25 is the same as 1025¢
And it's good to have a larger-number style and a smaller-number style, as humans struggle to read long numbers.

**Principais Problemas em Aberto na Física Clássica**
A física clássica, que inclui teorias não quânticas e, em alguns contextos, não relativísticas, ainda enfrenta desafios fundamentais. Abaixo, detalhamos os principais problemas em aberto, suas causas, impactos e possíveis soluções:
---
### 1. **Turbulência e as Equações de Navier-Stokes**
- **Causa**: A não linearidade das equações de Navier-Stokes leva a comportamentos caóticos e interações complexas em fluidos.
- **Impacto**: Dificuldades em modelar fluxos turbulentos afetam engenharia, previsão do tempo e aerodinâmica.
- **Possíveis Soluções**:
- Avanços em métodos numéricos (e.g., simulações de alta resolução).
- Investigação matemática da existência e suavidade de soluções (Problema do Milênio do Clay Institute).
- Modelos de turbulência baseados em teoria de campos ou aprendizado de máquina.
---
### 2. **Seta do Tempo e Irreversibilidade na Termodinâmica**
- **Causa**: A segunda lei da termodinâmica (entropia crescente) contrasta com a reversibilidade das leis microscópicas (Paradoxo de Loschmidt).
- **Impacto**: Questões filosóficas e físicas sobre a origem da direção do tempo.
- **Possíveis Soluções**:
- Condições iniciais do universo (e.g., estado de baixa entropia no Big Bang).
- Teorias de entropia em sistemas não equilibrados (e.g., teoremas de flutuação).
---
### 3. **Reação à Radiação em Eletrodinâmica Clássica**
- **Causa**: Partículas carregadas aceleradas emitem radiação, gerando forças de retroação (e.g., força de Abraham-Lorentz), que levam a soluções não físicas (e.g., pré-aceleração).
- **Impacto**: Limitações na modelagem de partículas em campos intensos (e.g., astrofísica).
- **Possíveis Soluções**:
- Reformulação das equações com métodos variacionais ou regularização de auto-força.
- Integração de efeitos relativísticos para estabilidade.
---
### 4. **Transição Laminar-Turbulento**
- **Causa**: Mecanismos subjacentes à formação de turbulência a partir de fluxos laminares (e.g., instabilidades não lineares).
- **Impacto**: Controle de fluxos em dutos e aerofólios.
- **Possíveis Soluções**:
- Análise de instabilidades secundárias e teoria de bifurcações.
- Modelagem de transições via simulações diretas.
---
### 5. **Caos e o Problema dos Três Corpos**
- **Causa**: Sensibilidade às condições iniciais em sistemas não lineares, como o movimento de três corpos gravitacionalmente ligados.
- **Impacto**: Limitações na previsão de órbitas celestes e sistemas dinâmicos.
- **Possíveis Soluções**:
- Métodos estatísticos para prever comportamento de longo prazo.
- Identificação de regiões de estabilidade (e.g., ressonâncias).
---
### 6. **Hipótese Ergódica e Fundamentos da Mecânica Estatística**
- **Causa**: Dificuldade em provar que sistemas clássicos exploram todos os microestados (ergodicidade).
- **Impacto**: Validação teórica da termodinâmica estatística.
- **Possíveis Soluções**:
- Estudos matemáticos rigorosos em sistemas específicos (e.g., gases diluídos).
- Uso de simulações para testar ergodicidade em modelos simplificados.
---
### 7. **Transição Vítrea e Sólidos Amorfos**
- **Causa**: Mecanismos dinâmicos da formação de vidros (desordem estrutural sem cristalização).
- **Impacto**: Desenvolvimento de novos materiais vítreos.
- **Possíveis Soluções**:
- Teorias de campo médio (e.g., Mode-Coupling Theory).
- Modelos de frustração geométrica e relaxação cooperativa.
---
### 8. **Dinâmica de Materiais Granulares**
- **Causa**: Comportamento complexo entre sólido, líquido e gasoso em sistemas granulares.
- **Impacto**: Otimização de processos industriais (e.g., transporte de grãos).
- **Possíveis Soluções**:
- Modelos contínuos com plasticidade e fricção.
- Simulações de elementos discretos (DEM) para capturar interações microscópicas.
---
### 9. **Mecânica da Fratura**
- **Causa**: Propagação de trincas em materiais sob tensão (concentração de tensões).
- **Impacto**: Segurança estrutural em engenharia.
- **Possíveis Soluções**:
- Teorias de peridinâmica para descontinuidades.
- Modelos multifísicos acoplados a efeitos térmicos e químicos.
---
### 10. **Acústica Não Linear e Ondas de Choque**
- **Causa**: Efeitos não lineares em ondas acústicas (e.g., solitons e choques).
- **Impacto**: Aplicações em medicina (litotripsia) e tecnologia de sensores.
- **Possíveis Soluções**:
- Métodos perturbativos e simulações numéricas de alta ordem.
- Estudo de dissipação e dispersão em meios não lineares.
---
### Conclusão
Esses problemas destacam a riqueza e complexidade da física clássica, mesmo em contextos não quânticos. Soluções exigirão avanços interdisciplinares, combinando matemática rigorosa, simulações computacionais e insights experimentais. A persistência desses desafios também motiva a busca por novas abordagens teóricas e tecnológicas.
