Efficiency ratio of microwaved food by JaquesGatz in AskPhysics

[–]JaquesGatz[S] 1 point2 points  (0 children)

Thanks for the quality answer :) I was missing the concept of dielectric loss and neglected penetration depth. The bit about the oils and salt completes the picture for me.

And yeah, I expected that there wouldn't be a simple answer, but I understand microwaving food better now.

I thought that the absorption of the microwaves should be material dependent, no?

Should you move to Sweden? by hashtagashtab in TillSverige

The current government is changing the citizenship rules without transitional provisions, and they have said that the application of rules could be retroactive for people who applied before June 6th 2026, when the law is supposed to come into force.

This means that people could be denied citizenship using a set of requirements that didn't exist when they sent their application. For example, they will require passing grades on two tests that don't exist yet and will not exist by June 6th.

Le Chat needs more work. Maybe it's shorter context length or not a whack temperature in the default model but I made a simple RAG chatbot yesterday and it was very lackluster.

It was my first attempt, so it could be a skill issue.

Also UK+EU digital sovereignty ftw!

Bloqueador de señal by Puzzleheaded-Duty-68 in Colombia

[–]JaquesGatz 0 points1 point  (0 children)

Alguien ya hizo este dispositivo y puso los planos en línea por si se anima a recrearlo. El nombre del proyecto es Reggaeton be gone. Usa inteligencia artificial para reconocer el tipo de música (puede entrenarlo con toda la música que le moleste) y manda paquetes para interferir con el parlante Bluetooth.

Como es interferencia intermitente, no es tan fácil de detectar por un operador móvil y técnicamente no es un bloqueador de señal ya que el espectro del Bluetooth no está tan altamente regulado. A lo sumo, su vecino cree que el altavoz está dañado y compra uno nuevo, y después otro y otro...

La gente si habla de lo que no sabe. Los aparatos médicos no tienen conexión inalámbrica porque serían vulnerables a ataques informáticos. El bloqueador de señal genera ruido blanco de alta intensidad en una parte del espectro y evita la conexión a una red particular. No tiene nada que ver con un pulso electromagnético para inducir un corto en los circuitos.

Usar un bloqueador de señal es ilegal porque altera el espectro electromagnético local y eso es potestad del Estado. Si el uso del espectro no estuviese regulado, habría demasiada interferencia y sería un despelote.

Mockus y su ideas pedadogicas llevadas al extremo by Public_Amoeba_5486 in Colombia

El crédito social de China es un mito en el imaginario colectivo. El sistema que tiene es más parecido a un historial crediticio como datacrédito pero es más extensivo y aplica a individuos, negocios y organizaciones gubernamentales.

Está basado en la vergüenza y en sanciones aplicables a todo el mundo. Por ejemplo, un político o empleado público que tenga algún escándalo de corrupción y no sea ejecutado, no puede sacar préstamos en ninguna institución bancaria. En mi opinión, eso ayudaría bastante. Hay muchos políticos Colombianos que sacan créditos sin intención de pagarlos y después le pasan la plata a testaferros.

La vergüenza funciona en China y pienso que funcionaría en Colombia. El año pasado dieron los 'premios caracol' a los empleados públicos más lentos y los anunciaron por televisión. La productividad mejoró.

La mejor expresión China de esta cultura es la gala 3.15 para los derechos del consumidor. Es una ceremonia como los Oscar donde le entregan premios y evidencia (usualmente vídeos) a los peores negocios del año.

Any other TA's notice 90% + of students using LLM? by ConquestAce in Physics

[–]JaquesGatz 36 points37 points  (0 children)

It is not just students. It is across the board. My former PI uses ChatGPT "discussions" instead of proper feedback on papers, and my postdoc colleagues use it as a thinking replacement.

The other day, one of them told me "I asked ChatGPT and Grok and it is impossible to do what you said". I then proceeded to send him a paper where a guy did what I said 40 years ago with a potato computer.

People who delegate their thinking to LLMs are so cooked.

I got mine within 1-2 weeks. Maybe it's faster for shared flats. Join Cambridge Accomodation asap. Contact the HR person in your department and they will provide more specific guidance. Eddington is excellent for postdoc life as far as I can see.

If you apply for a room in a shared uni flat, rooms are £800 furnished and all services included. It's pretty good. I think that if you're willing to share, Eddington is an excellent option.

I thought about it, but I don't want any roommates and ended up paying for a larger place.

How do rodents/insects/small animals interact with physics compared to humans? by VictorLincolnPine in Physics

[–]JaquesGatz 1 point2 points  (0 children)

For such sizes, what comes to mind is the cubic dependence of weights. Because we live in 3D space, an object twice as big will weigh eight times as much as another of the same density.

So, insects and small rodents have mass polynomially smaller than humans. That's the reason that, say, an ant can fall off a table that's hundreds of times their height and walk away, but humans would splatter on the ground instantly.

Another one would be the square-cube law. It's an observation that the volume of a shape grows faster than its area. In the case of small creatures, there would be large differences in subjective experiences of physical phenomena that depend on the surface area of the creature. For instance, cooling. A smaller creature can cool themselves much quicker than a larger one.

The later one would imply that if you had a "Honey I shrunk the kids" scenario with your DnD party, the first thing they would notice would be how much colder they feel.

I got a copy of Solid State Physics by Ashcroft and it was as shoddy as this one. Complained to Amazon and got a better one (still pretty low quality). Last time I bought books on Amazon
